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 less. Measures 5" x 3" x 2-1/4" tall, with a 6-foot cord that plugs into the wall and a grounded female plug for your sewing machine, rotary tool, scroll saw, or, if you really make a lot of banana Daiquiris, blender.
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.
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?
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?
These black aluminum alloy heat sinks have flared fins at 1-3/8" x 1-1/2" x 1/2" with (2) pins out one short side and (3) 1/8" mounting holes in the center. Wethinks these are PCB mounts for TO series chips.
Our black anodized channel-style heat sink measures 1-1/4" x 1-1/2" x 7/16" with folded back fins and a pair of 1/8" mounting holes in the flat center. Come on, you've got some heat to sink. Who doesn't?
When in the course of human surplus events you cannot get something to work, it becomes necessary to sell it for parts. This remote control outlet is such a case. The good news is, it has a 1-1/2" x 5-1/2" 10-button transmitter for entering a 4-digit code and a 2" x 5-1/2" single-outlet receiver. From the Newstar company, it includes instructions, which a clever person like yourself may be able to use to actually make it work.
semi-firmly believe this doohickey is an infrared encoder made to mate with a
¾” dia. motor shaft to sense position. 32 steps per revolution, it measures 2”
x 1-3/4” x 5/8” with (3) mounting wings and 4-lead 7-1/2” long wiring harness
and an Amphenol connector. No specs, but it was made right here in the US of A.
It’s labeled QUESTEK RD 9U010.
