Here’s something you don’t see everywhere. We have very, very, very assorted (new) blank circuit boards ranging from 6" x 6" down to 1" x 1", and we’ll send you (10) of them with our greatest intentions of giving you at least (5) different kinds. In assorted colors but mostely classic circuit-board-green-and-metallic, they were originally intended for kids’ robotic toys and games. Now you can use this dream assortment for soldering practice, one-of-a-kind art pieces, home décor (if science is your thing as much as it is ours), and probably about a hundred other things we’re not thinking of. Oooh—jewelry!

Perfect for hands-on hobbyists. Foot-pedal speed controls free up your paws to do the real work. This one's for 120VAC devices, and ideal for machines using approx 200W or 1.6A or less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a 2-foot grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.

You into vintage TV vacuum tubes in their original boxes? Us, too. We’ve got so many of them, in so many types and sizes, we’ll send you (5) different per order. It's a crap shoot of a deal though. Normally special orders don't upset us, but this time we’re not BK. Sorry, no special requests. We’ll close our eyes, reach into the bin and pull out the first (5) assorted we can get our hands around. We’ve got an eclectic mix of electronic and radionic tubes from brands like RCA, Slyvania, Raytheon, Standard Brand, Philco, Westinghouse, GE, Tung-Sol and Lindal. And they all look super-cool. Some are super expensive and some are run of the mill. These are new old stock. Great Ebay items! (Multiple orders in a short time may result in same assortment.)

Hey, DIYers—put a little light on the subject! With our assorted 12VDC infrared LED panels, you can light up, well, too many things to mention. Panels (and naturally their corresponding LED light grids), each assembly is approx 3” x 2” to 2” x 1”. Some have leads, others don’t. Some need soldering, others don’t. Some lights are white, others are amber. You’ll get what you get without throwing a fit—and then you’ll turn it into something excellent like you always do. Send us pics.

Okay, they’re just strips of metal, but CJ says one of each and a grapefruit will get you at least a “C” at the science fair. The copper electrode is 100mm long x 18mm wide  x .8mm thick (3.94" x .7" x .041”). The zinc electrode is 4” long x 3/4” wide x .027” thick and stamped “ZN”. And both of them are awfully useful for crafters and jewelry makers, too.

Rated for 10A at 250VAC, these normally closed thermal fuses will pop at 128ºC or 262ºF. The fuses themselves are 1/2" long but yours will be wired into leads of assorted lengths, because they were betooken out of coffeemakers of some sort. Never been popped, though, because then they would be useless and who'd buy 'em?

Elenco resistor and capacitor combo kit. Resistors come in 73 values and (5) of each value. Capacitors total 100 pieces in 21 different values. This is a great kit to have around as the components are in zipseal bags, and in a nice storage box, with all the values on the box. Another great Elenco item.

It’d be a siren, if you had this handy device, which is, coincidentally, a 12VDC electronic siren from Orevox. Measures 4" x 4" x 2" in white plastic with (1) red wire, (1) yellow wire, and (1) black wire, each 9” long. Part # R-35WS. Why do you need a siren? Hey, that’s up to you. If people didn’t need them, they wouldn’t make them.

Ok, we have to come clean here. We do not know a lot about these circuit boards. They have an 8-Segment LED displays and switches, ribbon cable and assorted components. What we do know is they are takeouts from AC units and may very slightly from the photo. So look at the photo, order some, and go make something.

This 4" x 3-3/4" x 1-3/4" medical take-out air sensor has (3) ports coming off the main 3-1/8" x 3/4" ID chamber, (2) leading to one sensor and the other leading to a second one, then through circuitry on a mounted PC  board leading to a 10-pin output connector. Also has a PCB-mounted 3V coin cell battery. The sensors have input, output and trigger voltage and a voltage output, but we have no specs. Nice parts and pieces, though.
