1 READ this manual Read it carefully. Questions? E-mail: info@unitunlikely.com 2 Unpack note Check whether you have got all the parts as pictured below. If not Contact us at: info@unitunlikely.com. in case your printed circuit board is not white you might have a different version of the lunchbox. This manual can be found at: www.unitunlikely.com/manualblackedition.pdf 3 note the pcb amount: 1 This board is called a printed circuit board (PCB for short). The side pictured below will be refered to as the top side. The legs of the components will be sticking out from the down side. North side west Side east Side south side 4 resistor 1k amount: 5 location: R1, R2, R3, R4, R5 note It does not matter in which direction you solder the resistors. Components that have this feature are called non-polarized. The resistors have color codes to indicate their resistance. Super convenient! Find the 5 resistors with the color code Brown-Black-Red-Gold and solder them on locations R1, R2, r3, r4, r5. 5 Resistor 10K amount: 2 location: r6, r7 note These resistors are color coded with Brown-Black-Orange-Gold stripes.s 6 Diode amount: 1 location: D1 note The diode is a component that functions like a “oneway-street”. It lets current go one way, but not the other and will protect the more sensitive components of the Lunchbox if you connect the battery on the wrong way. The diode is a polarized component. This means that the direction it is soldered matters. Make sure to check you solder it as indicated on the PCB. The grey band indicates the negative side of the diode. The grey band of the component should be on the left. 7 IC sockets amount: 2 location: ic1, ic2 note Solder the Sockets on the places indicated by IC1 and IC2. Mind the visual indication on the PCB and try to match it with the sockets. In case you didn’t, don’t worry it is more a convention in electronics than a crucial thing to safegaurd the Lunchbox from working. Furthermore, make sure that each leg is properly soldered and that no legs are connected to another. 8 note capacitor 10nf amount: 1 location: c1 103 there are three similar looking capacitor but only one has the digits 103 printed onto it and it should be slightly smaller than the other two. This is the capacitor you need to solder. The component is non-polarized. 9 capacitor 100nf amount: 2 location: c2, c3 104 note these capacitors are slightly bigger than the previous one. The digit 104 is printed onto them. 10 LED amount: 1 location: LED1 note A LED is polarized. if you look closely, has one flat side which indicates the negative side (-). Match the flat side of the LED to the flat side of the print on the PCB. Another tip: The long leg within electronics often indicates the positive side (+). Make sure that the flat side (with the short leg) is on the south side of the print. 11 LDR amount: 1 location: LDR note The LDR is a resistor that varies in resistance when it catches light. The LDR is non-polarized so it can be soldered in either direction. Please make sure that you do not solder the LDR to tight on the PCB but make sure that a small part of its legs still stick out so that you can eventually bend it in the direction of the LED. 12 potmeter 1m amount: 3 location: pot1, pot2, pot3 note Note that you have four similar looking components, however only 3 are 1M, the other one is 100K. The values are recognizable by the white print on the top. The text on top of this compenent should start with 1m. 13 potmeter 100k amount: 1 location: pot4 note This is the other potmeter. its text on top should start with 100k. 14 battery clip amount: 1 location: vcc + GND note Solder the Battery Clip’s red wire to the VCC and the black wire to the GND. The battery that matches this connection is a 9V. 15 headphone amount: 1 location: right side of the pcb note Solder the headphone connector onto the location marked on the east side of the pcb. Now give the PCB some time to cool down! The following components are sensetive to heat. A PCB stays hot a short while after you soldered a component. This excesive heat can damage the components in the next steps. Just take it slowly from here on and you’ll be fine~. 16 elco 1uF amount: 1 location: c4 note The negative side of the capacitor is distinguished by the grey stripe that has been printed on the side of its casing. Another tip: make sure that the longer leg of the component goes in the hole marked with a plus. Note that you have two similar looking capacitors look on the writings on the side for the right one. It is crucial that you solder this components on correctly in order for the circuit to work. The capacitor for the C4 location is black. Give the component time to cool down before progressing to the next step. the grey stripe shoud be facing the LED. 17 elco 22uf amount: 1 location: c5 note It is crucial that you solder this components on correctly in order for the circuit to work. Give the component time to cool down before progressing to the next step. This component should be dark blue (/purple) with a light blue stripe on its negative side like the elco from step 16. Solder it in such way that the light blue stripe faces de diode (on location d1). 18 ne556 amount: 1 location: IC1 note Put the NE556N IC in the socket soldered at location IC1. Make sure that the small gap of the NE556N IC is on the left side and matches the gap of the drawing on the PCB. Tip: if the legs are too wide, gently bend them inwards before pushing it in its socket. 19 ne555n amount: 1 location: ic2 note Put the NE555N IC in the socket soldered on location IC2. Make sure that the small gap of the NE555N IC is on the left side and matches the drawing on the PCB. 20 knobs amount: 4 location: pot1, pot2, pot3, pot4 note Click the knobs into the potentiometer. Push till they make a clicking sound and they are nice and secure. 21 punch out note The casing of the lunchbox is also its casing. To transform this cardboard box in the most awesome casing simply punch out the circles. They are partly pre-cut so a simple push of a pencil should suffice. Once you punched out all the holes slip the pcb into the casing ét voilá~! 22 note admire length: 20 seconds Optional but deserved. Wow, look at that awesome musical instrument you just soldered. Simply plug in a 9v battery and you are good to go!
