Buzzing Transducer
This little (12mm dia x 8mm thick) transducer makes that ultra-annoying buzzing modem sound, because it's made for a modem. Apply a square wave signal in the 2200Hz range at approx 6V and it will buzzerate for you. Well, who wouldn't? Sound pressure level is about 85dB, 80 Ohm impedance. Housing is marked for polarity. Printed on the top is RDI-DMT-1206. Application notes are at www.microchip.com, reference AN655.

Diskette Cases
Individual cases for 3–1/2” computer discs. The nice thing about these is that they are stiff enough to protect the disc but just flexible enough not to be brittle and break the way most “jewel” cases do. Red, blue, purple or gold, all are translucent enough to read interior labels. We pick your color.
