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.)

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?

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.

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.

This remote VGA receiver measures 3-1/4" x 3-1/2" x 1-3/16" and is made to use with the NTI CAT5 VGA remote system which allows VGA and sound info to be transferred up to 600 feet on a CAT5 cable. Don't have the system? Pop the rivets on the bottom and you've got a dandy project case, a PCB-mount 5.5mm barrel plug and 1/8" audio jack plus whatever you can strip from the PCB board.

The USB is here to stay. Admit it and lose the adapters. Take out one of your standard wall plugs and wire in this double USB outlet with a regular, 3-prong grounded outlet below. The USBs are 2.1 amp chargers. Measures 2-1/2” tall x 1-3/8” and fits standard single-socket wall outlets. This is the future. From GE.

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.
