You Say Breadboad...
And the manufacturer, Elenco Electronics, says Bredblox, but what’s in a name? These are just nice little breadboards for electronic experiments. The Elenco Model 9830 measures 6-1/2" long x 2-1/8" wide x 5/16" thick with (2) power busses up both long edges and (63) double rows of more busses. The holes for components and jumper wires are approx .050" each and multiple boards can be interlocked via tabs and ports on the long edges. The Elenco Model 9418 is 6-1/2" x 1-3/8" x 5/16" and otherwise the same as the 9830, but without the power busses. Now go invent something and get rich.

Resistors
We have hundreds of thousands of 1/4 watt resistors which we will send an assortment of (100) 1/4 watt resistors of at least (10) different ohm ratings. All have two axial leads, and 5% tolerance. Don't miss out! This is to cheep to pass up.

Make Something Musical
It's a take-out sound module, we just don't know what it were took out of in the first place. Nifty, though. Happy, arcade-style video-game music plays through its 2" speaker, punctuated with BOING!s and cartoon-ish laughter. Includes (2) flashing lights, a snap-on black plastic grill, a power/mode switch, (1) momentary push-button switch, and (2) sets of break-out contacts. Apply 6VDC to the red and black wires and it plays its little heart out.

Rectifier
Great for fixing your power boo boos up to 4 amps @ 100 Volts. (Forgive the pun, it is late.) The full bridge rectifier is a 4-pin single in-line package (SIP) type with an oval hole for heat sink mounting. 7/8" x 3/4" x 1/4" it should be great in a power supply!

Mighty Photo Cells
Designed for a high power and rather hostile environment (like a street light) these photo cells have values from 1.36 Mohms to 40 Mohms in the dark and from 50 Ohms to about 1000 Ohms in outdoor daylight. We pick what you get (2 different) in this range. 0.55" dia, they need a clear lens protecting cover if used outside.

LCDs
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.

Slide Pot
Nice little slide pot of the sort used for e.g. speaker volume control. Which is to say it is low wattage, probably under a half, but we don't know for sure. It has a 3/8" x 1-3/8" x 1/4" body with a 1/2" long constant resistance between the inside contacts, short between the outside, and 0-200 ohms variable between any inside and any outside contact. Circuit board mount. CTS SA 1315 8914.

Music Buttons
Any teddy bear worth his stuffing plays music. Tuck your favorite tune inside a bear, baby doll, bride's garter.... The 7/16" thick x 1-3/8" dia button plays several bars, music-box style, powered by a replaceable AG-10 battery.

Capacitors-No PCB'S
We have a bunch of can capacitors of the type needed to start many motors and blowers - or do other things. Check the table and see if we have what you need.

Antique Tuners
Or at least pretty old. The circa '70s car-radio tuner from Philco-Ford has a 6-position rotary switch with spring-loaded gears. Scrounge lots of capacitors, resistors, chokes, diodes, etc., from this tuner, or display one next to your favorite buggy whip.

Speak Into The…
It's not for a beginner, but this generic electret microphone capsule is just made for an intermediate science project. The capsule, which probably came from a cell phone or similar device, is nominally rated at 2.2K ohms. It's 7/32" thick x 3/8" dia, with (2) 1 1/2" leads terminating in a polarized 2-pin connector. Circuitry diagrams are available online at several sites.
