Wiring is 5V to red, ground to brown and timing pulses to orange. Use any 1-2ms pulses at 50Hz.

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.

Great little 12VDC oil-less diaphragm style air pump. For you techies out there it draws 40-300mA, 2.0 Litres/min, 350mm Hg max pressure. These are takeouts but in great condition. Outlet port is 5/32". Overall size 2-3/4" x 1-1/16".

From ET Tech, this series 23 liquid micro-pump draws less than 300mA at 4-6VDC (5VDC nominal) with a liter-per-minute flow rate and up to a 3-foot lift. Not submersible, but suitable for hot-water apps and continuous duty. Measures 1" x 1" dia with a barbed 1/4" right-angle outlet and a 3/8" OD inlet on top. Great for fountains!

Well, the pretty nice seven, anyway, in this 7-blade muffin fan, measuring 4-3/4" sq  x 7/8" and drawing 280mA at 12VDC. Spins approx 2000 rpm and pushes approx 74cfm. Comes with 8" leads and 3/16" mounting holes at the corners. Velleman® part #BLS 12/120.

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.

Nifty device that takes maxi air and squeezes it down into a mini condition. The device is roughly 6-1/2"" long x 6" tall x 4" wide. It has a 10 ft. cord that plugs into an auto lighter socket: i.e. it runs on 12VDC @ 10 amps. Air output is via a 12" hose with a variety of valve adapters for tires, soccer balls, rubber rafts, and just dusting off the environment. Complete with a 0-250 psi gauge. Which should be plenty of pressure to explode a weak bike tire or flimsy beach ball, so please be careful!

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 9-1/16". The motor measures 1-1/16"dia x 1-5/8" long and comes with 7" leads and a 2-pin Molex connector.

This 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.

Here are the ins and outs of submersible pumps for your DIY fountain.These small electric pumps run on 24 VAC (For low energy consumption.) from the included wall outlet adapter, are rated for continuous duty, have (3) suction-cup feet, an adjustable flow control and both a straight and 90° 5/16" tubing adapter. This little pump is roughly 2-5/8" x 1.5" x 2-1/4", has a 6-ft power cord with an in-line switch, and pumps 70 gal/hr @ 1 ft lift. Plug it in and go with the flow. Indoor use only.

Don’t get too excited--we don’t have Tesla parts. But we do have this honey of a reversible 12VDC gear motor from a kid’s ride-able toy car. Spins approx 75 rpm, draws 800mA no load and stalls at 11.5A via a 1/4” dia gear that runs through a multi-gear box to a 6-spoked, 2-1/2” dia hub. Will run with as little as 3VDC with plenty of torque. Unit measures 7-3/4" x 3-3/4" x 4-3/4" in a teardrop shape, with a pair of 3” leads and a Molex connector.

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.
