Buehler 4 to 12 VDC gear motor complete with encoder and lead screw assembly that converts rotary to linear motion. Attached to the lead screw is a plastic anti-backlash friction nut and a metal L-bracket that moves forward or
reverse depending on the polarity of the voltage applied to the motor. The assembly is attached to a 9 1/4" x 6" metal platform. The assembly was removed from new equipment. The Buehler gear motor runs at 90 RPM on 6VDC/180MA or 180 RPM on 12VDC/180MA
(no-load). The encoder requires 5VDC input. The TTL output signal is 50 pulses per revolution. Motor, gearhead and encoder are 4.25" long x 1.8" diameter. The lead screw is 4.45" long x 0.38" diameter. The L-bracket travels 2.25" per revolution.

These are thin-film Copper Indium Diselenide (CIS) solar cells. Recent production, first quality, made by a major solar manufacturer. 60mm x 60mm x 2mm thick (2.4" x 2.4" x .08") The active semiconductor material is deposited on
the front of the glass, tinned ribbons are bonded to the edges, then the whole cell is covered with clear tough plastic to protect the cell and ribbon. They are environmentally protected and ready to use. You just solder to the ribbon and mount them in
your project. The cells put out about 4.5VDC open circuit and about 100MA short circuit. Maximum power of the ones tested is about .25 watt (80MA at 3.2VDC). CIS is the most stable and rugged of the thin film solar technologies and is about twice as
efficient as amorphous silicon. It is more efficient under cloudy or partial shade conditions than crystalline silicon. CIS is also radiation resistant, and therefore often used in spacecraft applications. You can connect them in series for more voltage
and in parallel for more current. These should be good for walkway lights, battery charging, remote instrumentation or data loggers, educational projects and other DC electrical applications. Unlike amorphous silicon panels, CIS panels do not degrade due
to sunlight exposure. In fact after at least 2 hours of exposure to sunlight of at least 1/2 standard intensity, the output will increase by about 10%. With the first exposure, the semiconductor material is annealed and the output is then stable at the
higher level. (This is called light soaking). We have a very large quantity for immediate sale. Large quantity orders invited. Subject to prior sale. Special prices for exporters, resellers and large quantity users. Call Ted 514-739-8723

A GREAT EDUCATIONAL GIFT!

The H-racer is a micro-version of what engineers and scientists have been dreaming about for real cars: combining hydrogen with oxygen to generate a DC current to power an electric motor. Unlike a gas-powered car engine, the only
byproducts of this electrochemical process are electricity, heat and pure water. Recently named as one of the Best Inventions of 2006 by Time Magazine, the H...racer is now the best selling fuel cell product in the world. First step in bringing the world
a tangible vision for a viable hydrogen economy. With the H...racer, you can witness the power of new energy technology in the palm of a child? hand. Unique, patented miniature fuel-cell car and hydrogen refueling station. The Refueling Station creates
hydrogen by electrolysis using water, and once the car's hydrogen tank is full, the car can run on its own hydrogen fuel-cell system, with the simple flip of a switch.
