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.)

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've seen cords on lights—pull the cord, turn on the ceiling light—right? Well, this is the reverse. Tie the cord onto something on the ceiling, pull the bulb on the bottom and it lights up. Seems backwards, because it is, but it somehow makes sense when you want the light on the end of the rope, not on the ceiling, and don't you think you've been doing things right-side-up for long enough? Bulb is 40 lumens, cool white for indoors, and runs on (3) “AAA” batteries that the manufacturer didn't include.

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.

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.

With this 1.2K OHM 10% tolerance power resistor. Rated 3 to 5 watts, it has a ceramic block body 3/8" sq x 1-1/2" long with wire leads on ends, one of which is 1/2" long and the other 1-1/2". Any questions?

If so, you might understand this circuit board originally from an HVAC controller. Maybe better to have an artistic brainstorm and repurpose this pretty little thing. Might be fun to use as a part on a faux robot. (Fauxbot!) Measures 2" x 5-3/4" with a 2-digit alphanumeric display, (14) green LEDs, (9) push-button switches, a 12-pin connector with multicolor leads, and, because it is true surplus, no wiring diagram.

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.

Our inline filter helps rid your AC line of EMI and spikes. Rated for up to 16A at 250VAC. Has quick-disconnect terminals for the line and lead sides. Schematic is on the 1-1/2" x 1-3/8" x 1-5/8" housing.

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?
