These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.
These single-digit displays with (8) LED segments in a DIP draws approx 150mA between 1.5 and 2.5 VDC. This is numeric because some segments' pins are internally shorted. Common cathode ground. Yellow segments. Measures 28mm x 17.5mm with 13 pins.
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.
