Science Fare
Slightly larger than some of our hobby motors, this Mabuchi RS-365SH double-shaft motor is a good choice for science-fair projects. Its range is 6 VDC, 50 mA, 550 rpm to 24 VDC, 80 mA, 2,000 rpm. The 3/32" dia shaft extends 5/8" from the terminal end of the 1-1/2" x 1-1/16" dia motor, and 3/8" from the other end. It has (2) 5" leads.

ALL Things To ALL People
This deluxe ABS storage case is called a Store-It-ALL, and it does. But it could be called a Carry-It-ALL, for the sturdy handle and locking clasp, or it could be called a See-It-ALL, for its translucent lid. Or a Fits-It-ALL, for the removable dividers that let you configure it with any number of compartments from 5 to 26. But the 12" x 18" x 3" OA case should really be called ALL-I-Ever-Needed- To-Get-Organized!

What A Deal!
We don't know exactly what this doohickey is for, but we're sure that if we were selling it to the government, it would cost at least a couple of hundred dollars. Labeled an ASM Cable Sensor (JKM Part #QMPD9700-3493-01), it has (2) 32" leads and a 1/8" dia eye in a 17/32" x 13/32" x 3/8" casing. It has a nominal impedance of approx 120,000 ohms in normal ambient light, and will go down to 750 ohms in bright light. If you want a bulk price so you can peddle this to Uncle Sam, just call. We can talk.

Treat With Heat
Start with one naked wire or a number of them, and a piece of our clever tubing, and end up with nice, tightly covered wire. For the specific diameters below, our each is a package of (10) 12" pieces of heat-shrink tubing. For an assortment of sizes, our each is a dozen pieces of 4" long tubing. You'll get (4) pieces each in 1/8", 1/4" and 1/2" diameters. All sizes are black. All will shrink to trim diameters half their current size when heated to 125°C/257°F. If only it worked on waistlines.
