The components, oscilloscopes, prototyping boards, etc are kept in cabinets in the hallway outside Picardsaal. The key is normally kept by Roland Horisberger and is loaned to Tobi Delbruck for the spring semester.

The USB oscilloscope used for demonstrations is the Hantek DSO-2090 at http://www.hantek.com.cn/en/ProductDetail_44.html which can be purchased on ebay for about $160.
