Check here first! ECE Shop Parts Inventory Large inventory of discrete parts, list of parts on website: http://www.ece.illinois.edu/eshop/parts/ There will be a self serivce area where you can pick up your parts you want during business hours. (They are still unpacking, and will be ready soon.) ECE Shop Parts Inventory Ask Staff for Help • We are no longer required to fill out the part request form. • If you are unsure what part to use, do some research online. • If you are still unsure, ask the staff for help. They are all very experienced in varisou aspects of ECE. ECE Storeroom 1031 ECEB ECE Storeroom • Located in 1031 ECEB • A catalog of commonly used parts and items are kept in stock, list of stock parts is available on the website. – http://www.ece.illinois.edu/ecestores/ – Inventory includes hand tools, project enclosures, mechanical hardware, soldering supplies, and cables • Parts can also be ordered from link through the my.ECE website The link will appear soon! Order parts Ordering Through my.ECE • • • Ordering parts using the ≈$50 available for groups from the department. A greater dollar amount may be approved if the item is understood to be course property.
