ROBOT PARTZ

These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change. They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A. Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew. Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft. If you're looking for a power supply, we've got one. Just snip the plug of this regulated switching power supply and wire it up. 

Works on all of them except the ones stuck to your eyeballs. Corrosion-Be-Gone is a gel made to remove the schmutz from all types of battery terminals, circuit boards and contacts, on everything from cars to computer boards. Our each is a 0.3 oz jar.

Our each is a package of (2) steel tech rulers. One is 6” x 1/32” for the first 2-1/2” then 1/64” for the next 1/2” then 1/16” for the last 3”. The other is 150mm x 0.5mm. Both have sliding markers/pocket clips, and both have mm:inch tables on the reverse side. You’ll need excellent eyesight.

So you like Nickel-Metal Hydride rechargeable battery bargains? You choose a 4-pack of "AA" 2600 MAH or "AAA" 1000 MAH NiMH batteries, the recommended choice for electronics, cameras, games, cordless phones and toys.

No self-respecting number cruncher can afford to be seen without one of these fashion classics. We'll send you (3) classic white vinyl pocket protectors in the traditional 5-1/2" x 3-1/2" size. The front flap is blank so you can add your own name, business or drawing of your favorite Star Trek character. Order quickly; It's only a question of time before these are seen on the runways in Milan.

The correct answer is "I don't know; I've never toggled." If, however, you just want to turn something on and off, here's a choice of toggles for your switching delectation. The DPDT toggle is rated for up to 20A at 125VAC and has screw terminals below. Measures 1-1/4" x 1-3/4". No center-off position. The first DPST toggle is rated for 20A at 125VAC or 15A at 250VAC. Screw terminals on the bottom. Measures 1-5/16" x 3/4". The smaller DPST toggle is rated for up to 4A at 125VAC or 2A at 250VAC. Has 3/16" spade terminals on the bottom and measures 1" X 9/16". All the toggles come with switch-plates and mounting nuts.

Our each is a pack of (10) common cathode 5mm dia red/green/blue LEDs. Clear lens, 20mA rated for 100K hour life. 3V supply will work for all. You also get 100 Ohm and 510 Ohm resistors to step down 5 and 12VDC respectively. Luminous intensity is 4,000 mcd.

This little 1.5-3VDC motor draws just 15mA no load, which means it's just the ticket for solar-cell applications. At 3VDC it spins approx 600 rpm and stalls at 125mA. Measures 1-1/8" long x 15/16" dia with a 5/16" long x 1/16" dia shaft and 3-1/2" leads.

The manufacturer, Elenco Electronics, says Bredblox, but what's in a name? This is just a nice little breadboard 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. Now go invent something and get rich.

It’s magnet wire because it has a thin enamel coating so you can make an electromagnet, motor, speaker or whatever out of it. But it’s also just nice 26AWG copper wire for craft or other uses. You’ll get (100) feet of it on a spool to do with it what you will.

This nicely made 13-piece file set has a dozen diamond-encrusted files at 2, 4 and 6mm wide x 1-3/16” long with 120, 180, 300, and 400 grit surfaces. Includes a colleted 4-3/4” long aluminum handle, Go rub something the right way.

Like blue jeans, but for wires. So you can color-code those wires instead of getting all confused. You get a 10-pack of 12" long x 9/32" pieces of heat-shrink tubing, (3) each of white and red, (4) of black. Rated for up to 600V 125°C. UL.

This torquey take-out 6-24VDC (12VDC nominal) motor draws approx 250mA no load, stalls at 7.2A and spins approx 5700 rpm. Measures 2" x 1-13/32" with a 3/4" x 1/8" flattened shaft and may have a setscrew-mounted coupler that resembles a router bit. Has prewired leads. Mabuchi part no. RS-545SH.

Attention robotics boffins: Here's a nice, powerful 12-24VDC Mabuchi brush motor with a gearbox and pulley attached. At its nominal 24DC, it spins 45rpm, draws 280mA no load, and stalls a 750mA. 7.5 in-lbs of torque and is rated for continuous duty. Has a 3/4" long x 5/16" flattened shaft with a 4-5/8" dia x 5/16" wide (3/16" ID) single-sheave pulley attached, with a matching O-ring. The gearbox measures 2-3/4" x 3" x 9/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

This 3-5/16” dia double-sided wire gauge wheel measures from 0-36 AWG on one face and from .005" to .325" on the other. Not sure how to use this gauge? Just strip a bit of wire and slide it through the gauge slots, not the holes, until you find the smallest one it'll fit through. It’s for non-ferrous metals, which is pretty much all of what you run across anyway, unless you’re Ferrous Bueller.

You get a 10ml syringe of white silicone heat sink compound for use as a thermal coupling for electronics. High conductivity, low bleed and stable at high temperatures. Perfect for you electronic tinkerers out there with a sinking feeling.

Nice little pulley unit kit includes (1) pulley each at 50, 30, 25 and 20mm and (3) pulleys at 11mm, plus myriad bushings, a 3VDC motor, (2) belts and a belt guide, base, mounts and assorted hardware. Includes graphic assembly instructions, plus a couple of rudimentary drawings with suggested projects. It's a mechanical science project waiting for a home.

Don't wait or it'll all be gone. You get (4) pieces, 11 feet each, of 18-2 wire, polarized, black with a white stripe and eminently discardable spade-push terminals on both ends. (That's under a nickel a foot, cowboy.) Lamp cord, speaker wire, pretty much anything you run juice to.
