Introduction
1.1. Preamble
Montaña de Luz (MdL), which is Spanish for Mountain of Light, is a non-profit
organization in Honduras that houses children affected by HIV/AIDS. Many of
the children are orphans, and Montaña de Luz is the only family they know. The
Ohio State University began sending service teams to MdL in 2005 through a club
called Engineers for Community Service. The program has been a major success,
and their quality of life has continued to improve. This year, the Computer Team
will be completely updating the technology in the lab including new tables,
computers, and an a/c unit. The renovated computer lab will have the technology
required to enhance the education for all children at MdL.

2. Background
The preceding computer teams have made significant progress in improving the
technology at MdL. In 2005, the first computer team helped turn the on-site
morgue into a computer lab. In 2006, a concrete pad was installed to support a
satellite dish, but the project was not implemented due to permit issues. In 2008, a
smaller satellite that did not require a permit was installed. In 2011, the most
recent computer team updated the Internet system and software, repaired
hardware issues, and installed a protective storage cabinet. Ohio State University
teams have consistently played an important role in maintaining the Internet
communication technology at MdL. Our team plans to build from the work of
previous teams and give the MdL kids access to the best technology possible.
3. Problem Statement
The computer teams kept in contact with both Kristen Mallory, the in-country
director, as well as James Bettis, a long term volunteer currently helping out at
Montaña de Luz. After exchanging several emails, the team had a solid idea of the
technical conflicts they are facing and how to go about solving them.
3.1 Heat Issue in Computer Lab
The team has been informed the computer lab can get very hot at times. Room
temperature is typically 70 degrees Fahrenheit. The computer lab could be
estimated to be 82 degrees Fahrenheit on average and even greater during March,
the hottest and driest month of the year. Besides being uncomfortable, this could
also potentially cause damage to computer and electronic equipment. The 2011
Computer Team recommended installing a drop ceiling in the lab.
3.2 Hardware
Most of the computers at MdL are getting old and need to be repaired or replaced.
The three office computers for the director, administrator, and psychologist are
outdated. There are six laptops and one desktop in the computer lab. Previously,
there was only one printer in all of MdL, but they have recently received a
donation of a laser printer.
3.3 Software
The software currently installed on the computers at MdL is limited. The team has
been informed that new educational software, parental control software, and
Microsoft Office would be very useful.
3.4 Wireless Network
The Internet service at MdL has been improved since 2011. There has been a
more consistent connection but the speed has not improved. MdL is currently
paying roughly $110 per month with the HughesNet E-Consulting Plan, receiving
a symbol rate of 33 Msps and a speed of 54 Mbps (Betty J. Interview).

Post-Trip Documentation
3.5 Data Storage
Currently, the kids at MdL have no way to store their individual work. If they use
different computers on different days, there is no way for them to save and
continue their work.
3.6 Electric Grid
The distribution feeder serving MdL fails occasionally. The power is unreliable
and there are constantly outages due to reasons including but not limited to the
distribution feeder. MdL needs to have access to electric power during these
times.
4. Scope of Work/Objectives
Prior to departure, the following objectives were developed to solve the issues
that have been described in the problem statement above.
4.1 Heat Issue in Computer Lab
The team will not have sufficient time or resources to install a drop ceiling in the
lab but the idea will be recommended to future teams. To resolve the high
temperature issue in the computer lab during the summer, a portable cooling unit
will be installed.
First, the team researched different types of cooling units and consulted the usage
and power required with the instructors. The team decided to purchase a portable
evaporative cooling unit because it uses less energy and is still effective within a
small room like the computer lab.
Preliminary testing will be conducted to make sure the proper usage and
efficiency of the cooling unit. If preliminary tests results are satisfactory, the
cooling unit can be installed upon the first day of arrival. In the case that the
cooling unit does not meet our temperature requirements of decreasing the room
temperature to below 74 degrees Fahrenheit or is not energy efficient, it will be
returned and back-up plan of purchasing window air condition in Honduras will
be considered. The computer lab is 22’8” long and 12’9” wide. The cooling unit is
9,000 BTU and should sufficiently lower the temperature in the room.
4.2 Hardware
4.2.1 Computers and Rearrangement
The team has requested a donation of ten desktop computers from surplus
equipment at The Ohio State University. Due to transportation complications,
only eight of the computers will be brought down to Honduras. Three of them will
be installed in the offices and five will be installed in the computer lab. The
remaining two computers will be left with Dr. Merrill for future computer teams.
A webcam will be installed on the administrator’s computer.

Post-Trip Documentation
The wires in the lab will also be rerouted to prevent dust. The team has designed
the 3D view of the room before and after the rearrangement. Kids and staff at
MdL will be involved in this project. In the case that the plastic tables are kept,
the following arrangement will be used.
Figure 1: Current Computer Lab Setup
Figure 2: The Planned Computer Lab Setup after Renovation
4.2.2 Wooden Tables
The team decided that it would also be a great idea to switch from using plastic
tables to wooden tables, and is still considering this option. The teenagers living
at MdL will be encouraged to assist in the building process. The tables were made
of eight sheets of ¾” 2’ x 8’ plywood, sixteen 2” x 4” x 8’s and eight 2” x 2” x
8’s. The wooden tables were planned to encircle the room as shown in Figure 3
on the next page. The tables are designed to be durable and can encounter rough
treatment. Figure 4 on the next page shows the supports for the table.

4.3 Software
Software in the computer lab has been outdated. To address this issue, new
software was installed on every desktop system.
Due to the limited bandwidth at Montaña de Luz, the computer team downloaded
or obtained all software here on campus. The team obtained a donation of ten
copies of Windows 7 Ultimate from a member of last year’s computer team, eight
of which will be installed on the surplus computers we are bringing, and two of
which will be left in the cabinet for spares.

Firefox was the Internet browser used on all computers due to its reliability
and speed. Fox Filter, an extension for Firefox, was used on the lab computers
to block children from inappropriate content on the Internet.

RapidTyping, a free typing tutor, was installed on all computers to help to
kids learn to type on the computers. Typing games within the program allow
for enjoyable learning.

Byki Express is a language-learning program that will be also be installed. It
uses audio and visuals to teach kids the basics of English. Headphones will be
supplied to use in conjunction with this program.

Open Office is a great alternative to Microsoft Office and was installed on
each computer. It contains an imitation of Microsoft Word, Excel &
PowerPoint, and runs very similar to these programs.

Skype was installed on the administrator’s computer to use with the webcam.
This will allow for easier communication between MdL staff and
volunteer/service teams.

A variety of educational games, including Big Brainz, Sebran, and Seterra.
These games teach math, memory, ABC’s, geography, and more.
The operating systems and software was installed on all donated computers prior
to departure, and a USB drive containing software installation files was brought
for existing computers at MdL. The team will teach the staff and the kids in MdL
about the new software.
4.4 Wireless Network
The team decided to install a switchbox and two new bridges that will essentially
improve the connection. The Internet bandwidth will be assessed and a new plan
and provider will be researched and recommended.

4.5 Data Storage
To help the kids keep track and store their data, the team will hand out flash
drives ranging from 4-16 Gigabytes that have adequate storage for each kid and
staff member.
4.6 Electric Grid
Electricity has been a major issue in MdL. A weather station will be installed in
order to gather wind speed data throughout the year. This will provide future
teams with wind speed data that can be used to decide whether the installation of
a wind turbine generator is a reasonable solution to an unreliable electric grid.
Power surge protectors will be provided in the lab due to the large amount of
power usage.

8. Objectives Achieved
The actual schedule in section 7 summarizes the projects that were implemented
during the trip to Honduras. The implementation is different than originally anticipated.
The team faced many difficulties and issues but still succeeded in the following tasks:
(1) Addressing heat issue in Computer Lab.
(2) Setting up hardware.
(3) Installing updated software.
(4) Updating the Internet system.
(5) Addressing data storage issue.
(6) Installing weather station for electric grid.
Each of these areas is described in detail in the following sections:
8.1 Heat Issue in Computer Lab
A few days before departure, the team learned that the air conditioner purchased
online in the U.S. was too large to bring on the airplane. It would require an additional
cost of about $200 and one less computer could be transported. The team decided not to
transport this air conditioner and return it for a refund. Instead, the team would explore
other air conditioning options in Honduras.
Once in country, the team purchased an air conditioner in Tegucigalpa. The air
conditioner consisted of an indoor unit and an outdoor unit with two insulated pipes
carrying cold air between them. The old window a/c unit was taken out and the window
was sealed with bricks and four 1” PVC pipes in the corner for Ethernet, drainage hose,
and two copper tubes as shown in Figure 8. The units required a vacuum pump and
coolant that was not readily available. Due to these unplanned difficulties, the team was
not able to install the a/c during the week and instead hired a technician to finish the
installation. The unit was installed weeks after the team has left Honduras.

8.2 Hardware
8.2.1 Computers and Rearrangement
The rearrangement of the room was implemented to take into consideration the
room being used as a computer lab and a school room. The room was arranged with two
tables against the North wall and two tables back-to-back against the West wall as shown
in Figure 10.
Eight new HP XW6400 Workstation computers were installed at the orphanage,
three for staff and volunteers in the office and five in the computer lab. Every computer
was equipped with a keyboard & mouse, Ethernet cord, and a monitor. Due to the
inability to transport two computers, two extra monitors were used to set up dual monitor
computers for Kristen and Ana. A webcam was also installed on the volunteer computer
in the office.

8.2.2 Wooden Tables
The team decided to construct wooden tables as opposed to rearranging the plastic
tables. Four tables, each 8’ long and 2’ wide, were built and placed inside of the
computer lab. The tables were built out of wood with four legs each, 2¾” sidings, and
supports in the middle. Each table is durable enough to last through rough treatment and
support the weight of several computers. Wood is also much more resistant to heat than
plastic, eliminating the problem of deformation. The tables were sanded and painted with
two coats each (two tables purple and two tables light blue) with the children as an
interaction activity as shown in Figure 12.

8.3 Software
Each computer installed by the team was equipped with software prior to the trip.
The software installed consists of Windows 7 Ultimate OS, Open Office, Rapidtyping,
Byki Express, Firefox, and various educational games. Skype was also installed on the
one office computer with the webcam.

Technology Integration
Post-Trip Documentation

8.4 Wireless Network
The team was not able to accomplish a reconfiguration of the wireless network
due to insufficient knowledge of the current network. The Netgear switchbox was
installed on the wall in the computer lab and replaced the old black switchbox. The old
black switchbox was placed in the office to allow for the extra computer to be plugged in
to the network as well. The old EnGenius bridges were replaced with a newer model of
the same bridge. One of the bridges was infested with ants. After making these changes,
the team soon learned that the bridges were not involved in the wireless network at all.
The team attempted to plug in and configure the new bridges as access points so a
stronger wireless network would be available. However, there was much difficulty and
the bridges were not able to be successfully configured. They were left plugged in a way
in hopes that they would somehow strengthen the network. Upon returning to Columbus,
the team learned that the Wi-Fi was not working at MdL. After a few emails and phone
calls to troubleshoot, the wireless was restored after both of the EnGenius bridges were
unplugged. The team began researching and realized the bridges were interfering with the
router and existing access point, causing them to malfunction. The only change made to
the network was the addition of a switchbox. Although the Internet could not be
improved, the team gathered valuable information to provide to future teams. A clear
outline of the current network setup and precise instructions on the resources and changes
that could enhance the wireless network is included in this documentation.

8.5 Data Storage
To help kids and staff store their data, the team gave 41 flash drives ranging from
4-16 Gigabytes to the staff to be handed out to the kids. This is sufficient storage for
each kid to hold their personal data. They will not have to worry about which computer
they use as data can be carried with them and accessed on any computer.
8.6 Electric Grid
The team installed two power surges in the computer lab and a weather station.
The weather station was installed on top of the agriculture water tanks behind the
schoolhouse as seen in Figure 17. The weather station provides data year-round and can
be stored on the staff’s computer to be emailed to Ohio State or other service teams for
future development of wind energy. Wind Speed data from March 15th to April 16th is
shown in Figure 18, and the average wind speed was calculated to be 2.5 m/s. A 1 kW
wind turbine is within reach of building with the cost of materials totaling less than $200.
A link has been included in the references on how to construct one of these wind
turbines. During one particular month at the orphanage, 3268 kWh was consumed,
18 | P a g e
Technology Integration
Post-Trip Documentation
costing 18,013.81 LPS or about $900.70. This is equal to about $0.28 per kWh. The
wind speed would need to slightly increase for the wind turbine to be optimal, but we
have only gathered one month of data and it is possible that other months of the year
bring higher wind speeds. If one of these wind turbines can be successfully constructed
and connected to the electric grid and the average wind speed can reach 5 m/s, the 1 kW
turbines could produce around 1,000 kWh annually. This would equate to $280 in yearly
savings, and possibly allow MdL to have access to some power even when the main
power is down. Multiple wind turbines could greatly increase these savings, provided that
the first prototype is successful. Future teams can use recorded data to find accurate
savings.
Power is calculated using the following equation:
1
𝑃 = ( ) ∗ 𝜌 ∗ 𝐴 ∗ 𝑣3
2
The variable 𝜌 is the density of air, therefore a constant and not a variable. The two
variables are A, the area swept by the turbine blades, and v, the speed of the wind.
Therefore future teams should note that in addition to larger wind speeds generating more
power, using longer turbine blades are also be beneficial to wind energy production.

9. Sustainability Statement
To address sustainability, the team worked on keeping the computer lab in
working order. Although the deliverables are mostly inside, the team utilized outdoor
grade material wherever possible to extend the lifespan of the equipment and prevent
damage and corrosion over time. A variety of spare equipment was left in the cabinet in
the computer lab. The equipment includes a few keyboards & mice, as well as several
spare Ethernet cords, power cords, and DVI cords. The old bridge that was not infested
with ants is also in the cabinet, along with an old D-Link router that was not in use. The
instruction manual for the new bridges is on a CD in the cabinet, and the CDs and
instruction manuals for the weather station and webcam are in the top desk drawer under
the volunteer computer with the webcam. The cabinet is pictured in Figure 19, Appendix
16.1.
The computers brought down were preloaded with software that will educate the
kids, and the programs will not require any necessary updating. Fox Filter, an add-on for
Firefox installed on each computer in the lab, will prevent children from accessing any
inappropriate content as well as block all harmful malware. When an administrator logs
on one of the computers, they will automatically be notified of any updates for Fox Filter
and can then update every computer. Updates to Fox Filter will make sure the computers
are not vulnerable to the newest malware. Windows is set to automatically download and
install critical updates overnight when the bandwidth is not limited.
The weather station that the team installed at MdL provides valuable wind speed
information at the orphanage to future service teams. This will allow future teams to
research and consider providing more sustainable energy solutions to the orphanage.
The heat in the computer lab is considerably lower with the new air conditioner.
The unit will ensure that the lab stays at a reasonable temperature and maximizes the
20 | P a g e
Technology Integration
Post-Trip Documentation
lifespan of the computers, prevent the plastic tables from deformation if they are kept in
the room for schoolwork, and provides a more comfortable setting for the kids that will
encourage learning. The four new wooden tables are durable and sturdy enough to last a
long time and support the weight of many computers. They will also not deform like the
plastic tables did.
To help each kid have adequate storage, flash drives with enough memory for all
the needs of a child were given to staff. This allows each kid to have enough data for
their educational needs and also for non-educational uses such as music.
10. Recommendations for Future Teams
(1) MdL is located on the top of a mountain with a good source of wind. The team
experienced an extended power outage during the short time there, and the power grid is
clearly expensive and unreliable. An alternative sustainable and independent energy
source is recommended and needed. The primary purpose of the team setting up the
weather station data collector is in hope that future teams could implement and replicate
the alternative energy wind generator project that Choluteca team 2012 has completed
(See reference for link). Keep in mind that the wind generator implemented by Choluteca
team is designed to supply energy only for lighting, a battery charger, and a box fan.
The computer team has been in contact with long term volunteer James Bettis for
wind data throughout the year. Future teams can email Kyle Sherman at
sherman.1344@osu.edu for an invitation to the wind data dropbox.com account, and a
further look into research and a study regarding wind turbines is necessary.
(2) Ask the staff for feedback on the Open Office word processing software that
was installed on all of the computers. If available at little to no cost, the switch can be
made to Microsoft Office.
(3) Keep in mind that MdL internet bandwidth is strictly limited, any large
download or upgrade could cause the entire internet system to slow down and terminate
as the team has experienced. The bandwidth is limited to 400Mb per day and is unlimited
from 1 am to 5 am Honduras time.
(4) Update all software and use extract parts for extra computers to replace
hardware if necessary. Software updates should be done and tested in U.S. before
departure.
(5) Keyboards need to be changed to Spanish version if they haven’t done so.
Easiest way would be purchasing Spanish keyboard layout stickers and switching the
keyboard layout on the computer to Spanish.
(6)MdL website hasn’t been updated in a while. It needs to be professionally
redesigned and updated.

(7) Internet recommendation: Replace the current ASUS router with a new
300Mbps router. Replace the access point in the dining hall with a new 300Mbps access
point. Plug in the EnGenius wireless bridges above the office and above the computer
lab. When installing, unplug everything and begin with the router. Access the router
configuration through 192.168.1.1 in an Internet browser on a computer plugged into the
new router. Enable DHCP on the router and change the IP address to 192.168.0.1,
because all devices have a default IP address as 192.168.1.1 and they will interfere if you
plug in multiple with that address. Create a secured network and enter an SSID and
passphrase. Then, plug in the switchbox in the office, which should be connected to the
switchbox in the computer lab. Replace the access point in the dining hall with the new
access point. Using a computer in the lab, type in 192.168.1.1 to configure this access
point. Set up the wireless network with all the same settings as the network on the router.
This means same SSID, same security, and same passphrase. Change the IP address of
the access point to 192.168.1.2 and disable DHCP. DHCP is what assigns IP addresses to
all computers on the network, and only one device on the network can have it enabled or
else they will interfere. Then, plug in the bridge from the network side of the power
adapter to the switchbox. Type in 192.168.1.1 in the browser on a computer in the lab,
and set the operation mode of the bridge to access point. Then, edit the wireless network
settings to once again have the same security, same SSID, and same passphrase as the
previous two. Set the IP address of this EnGenius access point to 192.168.1.3 and disable
DHCP. Finally, plug in the EnGenius Bridge in the office from the network side of the
power adapter to the switchbox. Type in 192.168.1.1 from a computer in the office and
change the operation mode to access point and enter the same wireless SSID, security,
and passphrase one more time. The IP address on this one does not need to be changed
because it is the only one left with the default address, but DHCP does need to be
disabled.
11. Lessons Learned
The group learned many valuable lessons while in country including the
following:




Make sure all software is updated in the U.S. The internet bandwidth is very
limited and cannot be used for updates while in Honduras. It is very inconvenient
to work during the night hours where the bandwidth is unlimited.
The group should have considered all possible problems that could be
encountered while in Honduras. There were many unexpected problems that we
occurred such as internet being unavailable, not having proper equipment for a/c
unit installation, and not enough tools for wood working. Many problems could
have been foreseen if more information was given so the group provided
information for future group projects.
Research on the network bridges should have been performed while in the U.S.
The real problem with the Internet connections can be resolved with a new router
and new access points with faster speed limits.
The group learned to be careful with all equipment used. While painting the
tables, the group used an oil based paint that would not come out of clothes or
22 | P a g e

skin without paint thinner that was not readily available. The kids should not be
involved with equipment that can make a mess or can be hazardous.
The team encountered a problem with the luggage weight on the airplane. While
the group is preparing to buy equipment, a running tab of the weight and
dimensions of objects could be kept. The group was not able to take 2 computers
and an a/c unit on the airplane.
12. Cultural Experience
Honduras is a country full of amazement and traditions. The team has experienced
many traditions while adventuring around the cities and locals. This includes an everyday
5-9 schedule for most of the Hondurans. The majority of their buildings, houses, and
roads are built on and around the mountains. The military also has a clear presence
throughout the country, and they can be seen in the middle of many of the streets holding
large guns, which one would never see in the United States. It was memorable to
experience the fun tradition of celebrating birthday Honduran style with the kids at the
orphanage.
13. Intersection of Engineering and Culture in a Developing Country
Engineering in a developing country of a completely different culture can be very
difficult, even with extensive preparation. Development of projects needs to be prepared
to the best of the group’s ability before departure to the developing country. The group
needs to keep in mind that the resources available to them may not be available to them
in the developing country. A successful project in a developing country will use
resources that can be obtained easily at the project’s location. There are many obstacles
that can set back a project, and no project ever goes perfectly as planned. Culture shock
is also something experienced when traveling to a new country, as the daily life and
culture of people in Honduras is completely different than that of Americans. A language
barrier can be time consuming and restricting when communication is needed. The lack
of consistent electricity should be expected and the group should have to tasks ready to
perform if the electricity is not available. A group must also not to expect for an exact
product to be readily available in a developing country.

17.2 Appendix: Communication
The following three pages contain emails sent by the team and the staff at MdL.
Plain text corresponds to the team’s words and any red or italicized text was written by
the staff at MdL.
Has the staff of MdL seen any improvement in Internet speed since 2011? HughesNet,
your Internet provider, has supposedly gotten better worldwide. I think we talked about
this but we think there has been a more consistent connection but not better speed.
Are all the computers in the lab connected via Ethernet cables? How many extra Ethernet
cables are located in the box on top of the cabinet? (One box should be marked internal
27 | P a g e
Technology Integration
Post-Trip Documentation
and the other marked external) All six laptops and one desktop have Ethernet available
for their connections. I only can find one box that says "extra computer parts" and it had
27 ethernet cables including two very small ones. (As long as none of those are old dialup cables)
What software/product keys for software is on the labeled DVDs in the cabinet? I only
found an open MS Office in Spanish CD and Windows 7 without keys. I know that we also
have MS 2010 with keys, that are currently installed on the laptops.
How much does MdL currently pay per month for Internet services? Are they willing to
pay a higher monthly fee for more bandwidth? 2,200 Lps roughly $110 The plan is
called E-Consulting and from what I can tell in the system info it says we have a receive
symbol rate of 33 Msps. On my computer it says 54 Mbps is the speed.
Is there any way to recycle/sell broken or old computers in Honduras? Still working
computers we have given to staff or community members or maybe sold, I'm not sure. To
recycle computers we do not yet know of any program.
Can you send us a picture of the computer lab? What are the dimensions of the computer
lab? 272" by 153" are the dimensions of the lab.
As we learn from the 2011 computer team's report, MdL is currently operating on
Windows 7, we were wondering if they need any more copies of Windows 7. Do you
need any more copies of Microsoft 2010? We do have some copies of Windows 7 but I am
not sure if they all work. Additional copies would be appreciated but maybe only one or
two. We do need Microsoft 2010 and Windows 7 for two of the office computers.
Office Computers: The two office computers for the director and administrator are in
need of being updated or maybe replaced. If they can be replaced then the computers
could be cleaned and used in the volunteer office as we are currently using our personal
computers. Here are the specifics on the office computers. Ana's computer has Windows
XP Pro Office 2002 and 2.54 GB free and 37.2 GB used. Kristen's computer has XP Pro
as well and Office 2002 and 34.5 GB free with 74 GB of total space.
We were wondering if the office needs a webcam for future conferences.(would you like
a copy of Skype?) They thought a webcam would be a great idea and so would a copy of
Skype.
Whether or not more computers are needed for both the lab and the offices, or replaced
with new ones.(laptops or desktops) Sounds like the administrative office prefers desktops.
I think the volunteers would be better off with laptops but if we inherit the old desktops
from the admin office that would be fine.
Also the computer lab does have locks on the wall that leave room for three additional
computers. We have two laptops available but one was going to be used for volunteers.
The second has an admin log-in that is unknown to anyone at MdL.

How is the condition of the internet? Wireless or Ethernet? Does it need to be improved
or replaced? The internet is wireless but as you may know it has limited bandwidth and it
appears to be affected by weather. It really does need to be improved. I'm not sure if the
routers are the problem or the internet service provider or bandwidth. If you want more
information about those things let me know and I can look into it.
Do you need help moving the internet modem to the new office? I'm not sure what you
mean by this, please clarify.
If anything is needed with the internet, can we have the router brand and model
number? Also any current security systems? We heard that you guys might want to
implement a parental control for the internet. Supposedly we have a firewall but I have no
details about it. Here are the routers and information about them.
The office has two routers: a Hughes HN7000S IP.S and ASUS WL-500G Premium v2
In the computer lab there are other routers that are not being used: Another ASUS WL500G PV2, A Wired Router D-Link DIR-100, and 4 EnGenius Broadband Bridges (I
think) model numbers EOC2611P (2) and EOC-2610 Long Range (2) One bridge
appears to be in use above the lab but I am not sure if it is actually working.
In an office near the back of the compound there are also these routers and other
equipment: Linksys WRT54GS Broadband Router, TP Link 54 Mbps extended range
wireless access point and an ASUS GX100SB Desktop Switch. All of these things were in
the psychologists office but are now available to be moved. The only reason they would
remain there would be to provide internet to the back buildings where groups and staff
stay.
Also we would like to reactive or implement a parental control to protect the kids from
inappropriate content.
We heard that you guys might want separate accounts for each kid on each computer. Do
you want kids to be assigned computers? Or would you like the students to be able to log
onto any computer and access their account(which would require a server, I believe)? We
think it would be great to have separate accounts for kids who are age 12 or older right
now. Would that be possible? If we need a server we could possibly use one of
the unused laptops as a server, or there is also one that has a cracked screen. It would be
best given our setup to use a server, not to assign kids to specific computers because of
only having six that work routinely.
Would you like a bridge in the computer lab for students?(a router that connects to the
modem to increase signal strength.) If you think that a bridge would help that would be
great. At least we could test the bridge that is above the lab right now to see if it works. If
you need to know I can check to see if the three remaining bridges we have work. (As
long as someone could explain how to connect them to the network).
Are there any educational software programs that you would be interested in us
getting? We are interested but the Tia in charge does not have any specific ideas. One
29 | P a g e
Technology Integration
Post-Trip Documentation
that I can think of would be a typing program in Spanish. That would be very helpful. Any
other ideas you have would be welcomed.
Is heat still an issue in the computer lab? We had an idea to grow some plants (vines or
vegetable of some sort) on the sides of the building. Is this reasonable?(other ideas) The
Tia said that heat is an issue during the hotter times of the year. We do have some
chicken wire on one side of the lab but the plants need to be cultivated a bit more.
Would you like us to bring laminated flyers or instruction sheets for common problems
related to the computers? (If the kids have common problems that persist, like accessing
the internet.) Yes, that would be great. How to save a file in Microsoft Word would be
great, or how to transfer files from the computer to a USB memory (if you can bring
those). Other ideas are: how to copy and paste information, and any other common
problems you can think of.
Any needs for a printer? Yes we have the need for at least one in the office or in the
computer lab. We currently have one HP Deskjet F4480 that will be put into one of those
places.
Would you like us to bring a bunch of flash drives for the children and staff? We think
we can gather a large amount from lost-and-founds throughout the school. Definitely!
Most of the big kids have flash drives but they are constantly full of music so it would be
nice to give them one that is used only for school. If you can we could use 30 flash drives
for kids and 10 for staff. Any combination of that would be great, thanks!
Are there any other issues or suggestions? One idea that I have is to bring compressed air
cans to be able to clean the machines and even printers. Or if you have any other ideas
on cleaning maintenance a time to teach that to some staff members would be great!

17.3 Appendix: Internet Documentation
The following document was emailed James Bettis:
Internet Documentation
To configure either EnGenius ENH500 Bridge:
1. Make sure only one of the bridges is plugged in and type 192.168.1.1 in a browser
on a computer connected to the same switchbox as the bridge.
 Sometimes you have to refresh it a couple times.
2. Type in the username and password, which are both admin.
3. On the left hand column under wireless network or SSID, there is probably one
network or SSID that has enabled checked.
4. Click edit on that one, then you can change the SSID which is the name of the
network when you connect to it if you want.
5. In the wireless security part you can change that to WPA2-PSK then enter a
passphrase for the network.
6. You then need to click save then save/reload at the top of the left column.
7. In order to configure the other, go back to 192.168.1.1 on the bridge already
configured and change that IP address to something different, such as 192.168.1.2
 You can then access the other bridge at the default IP address without the
other interfering.
If Internet goes down:



Check bandwidth
1. Type in 192.168.0.1 in the browser of any computer connected to the
Internet.
2. Click usage and see if the bandwidth for the day has run out. If so, the
Internet will be back up the next day.
Restart Router
1. Unplug the power cord to the ASUS router in the office.
2. Wait one minute then plug it back in.
Reboot Modem
1. Type in 192.168.0.1 in the browser of any computer connected to the
Internet.
2. Find the reboot option and press it. Wait for the modem to reboot.
