Tiny Puffer
Our diaphragm-type air pump draws 80mA at 3VDC and has a 1/8" OD outlet. It's small and mounted on a small PC board (1-3/8" x 11/16" x 7/16" OA). Yours may or may not have 4" leads. If not, the positive wire goes to the longer of the motor leads. Comes with a self-adhesive strip on the side opposite the PC board. Originally designed to activate an equally small air-pressure switch.

Aluminum, On A Roll
Mega-useful aluminum tape. A 2" wide x 50-yard roll of .004" thick aluminum on a 3" core. Has a paper backing and is conductive on the non-adhesive side. Reflects heat and light, useful for seaming riveted aluminum sheets, particularly good for cold weather and metal repairs. Our fisherman friends love to wrap wooden lures with it and work it with a piece of soft wood for metal-finish effects.

Little Giant
Call it the Stephen A. Douglas of gear motors-small, but more than able to go up against the big guys. From Pittman Mfg (part # GM8224), this permanent magnet, reversible, 328 RPM, 24VDC motor runs anywhere from 6-24VDC with exceptional torque throughout the range. No load current draw of 180mA. Stalls at 5.54A. Torque rating of 3.09 oz-in. Overall size is 3-3/8" long x 1-3/8" dia with a 3/16" dia x 11/16" flattened, hardened shaft. Leads are 5" long terminating in a 2-prong plug. Pittman says "self-aligning, sintered bronze bearings and diamond-turned commutators."

Clip Lead Set
Ten electrical leads with an alligator clip on each end. Each lead is about 20" long, not counting the 'gators. Vinyl coated 20-22 ga. wire with a vinyl cover over each clip. They come in an assortment of five colors with two leads in each color. The manufacturer calls them heavy duty but we would restrict them to the light currents and low voltages you will be using in your home experiments. Our each is a set of (10).

AIRCRAFT CABLE
Stop picturing a fat cable you can use to tie down an airplane. This is great 20–strand twisted cable from the aircraft industry, but at 1/16” dia, it’s sized more for a Chicago Cub than a Piper Cub. The cable is high–quality stainless steel, unjacketed and very strong. Use it to hang extremely heavy mirrors, make repairs, create bendable metal sculptures! Order in 15–foot or 100–foot hanks. Enjoy!

You Say Breadboad...
And the manufacturer, Elenco Electronics, says Bredblox, but what’s in a name? These are just nice little breadboards 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. The Elenco Model 9418 is 6-1/2" x 1-3/8" x 5/16" and otherwise the same as the 9830, but without the power busses. Now go invent something and get rich.
