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.

WE CALL IT BY DIFFERENT NAMES... Earthquake Machine, Grand-Daddy Vibrator, and more... This is a unique product from Surplus Traders. Basic motor is 1.4 inches in diameter and runs on voltages from as low as 4 volts to as high as 14 volts. Low current consumption: 200ma@5VDC, 1000ma @ 7VDC, 2.0A @ 10VDC and 2.2A @ 12VDC. Maximum speed is approx 5000 RPM, but operation at this speed, with this weight, is not recommended. Can be used to vibrate: containers, fluids, wall, beds, chairs, deer feeders, etc. Ideal as a signalling device for the hard of hearing, as well, when attached to furniture, doors or walls. We have had many, many requests for a motor of this size and power and now have it available. Order being taken now for future delivery. NOTE: due to the vibration magnitude, this motor is NOT recommended for "personal" devices unless the motor and weight are fully and securely encased. Contact Ted Duskes at 1 800 341 6468 or Ted to reserve your stock now and negotiate large quantity pricing! Are your prototyping a new product? 3 sample units - $100 shipping included (to new product developers only! Click the "more info" icon for a different view. NOTE: it is recommended that this motor always be used in an enclosed (preferably ventilated) housing to prevent injury as the rotating weight has high destructive force capability.
