No Mount Motor

Our motorman, CJ, called this reversible 12-24VDC motor strange, mostly because it has the power contacts mounted on the face, bracketing the 11/16" x 1/8" mostly striated shaft, and has no mounting brackets. But that shouldn't stop a clever person like you. (Hint: it was probably made to fit into a sleeve of some sort.) At 12VDC, draws 100mA no load, stalls 850mA and spins approx 900 rpm; at 24VDC, draws 150mA, stalls 2.2A and spins approx 1800 rpm.  Measures 2-1/4" x 1-13/32" dia.

Ten Roentgens & Counting…

If Madame Curie had owned this, she'd be alive today. (She'd be more than 140 years old, of course, but still….) Our Radex RD1503 digital radiation meter evaluates the ambient level of gamma radiation, and can detect objects polluted by beta active radioactive nuclides. It uses a Geiger counter to detect the amount of gamma radiation within 40 seconds. It indicates the ambient dose equivalent in µSv/hr (0.05 to 9.99) and the µRem/hr exposure dose rate on a scale of 0.1 to1.25. The values are displayed on a 1-3/4" x 1-1/8" LCD screen. The presence of each particle is indicated by a clicking sound, for quick identification of affected areas, and it has an audio alarm with 3 adjustable ranges. The unit measures 4" x 2-1/4" x 1" and comes with a detailed manual and technical certificate. Requires (2) "AAA" batteries. Made in Russia. CE.

Our 4-1/2" long x 2" wide x 1" deep cell phones fit nicely in this black-leather carrying case. The front is a 2-1/2" x 1-5/8" window of clear plastic through which you can press the buttons. The case is open on the bottom so you can access the ports, and comes with a 6" wrist strap and a plastic belt/pocket clip. A small strap snaps over the phone antenna to keep it from slipping out. Unfortunately, if your phone doesn't have an external antenna, there is nothing to keep it in except a snug fit, an extraordinarily rigid posture, and a determination to never bend over.
