In this video I show that this little engine can drive a 20" fan at 570 rpm while charging a 12-volt battery and running a 12-volt pump to provide its own cooling water, all at the same time. Note that it's charging the battery at about 1 watt. At the end I show the engine just charging the battery and putting out 4 watts of electrical power (13.25 volts x .304 amps = 4.028 watts). The engine drives an inkjet printer PM motor as a generator using the original toothed drive belt for higher efficiency. The little 12v pump is one I found online and runs off the generator. With the rheostat I can control the water flow from it, and also the current draw. It's pretty satisfying to see one's engine operating standalone and doing some useful work. The large Stirling engine in the background is another experiment.

TX4000 - T-shirt Printer
TX4000 - T-shirt Printer Tube. Duration : 2.97 Mins.
This is a dual four color (CMYK) digital flatbed printer. A dual 4-color ink printing mode enable fast printing with a stunningly beautiful color prints of exceptionally accurate reproduction and superior shadow details. TX4000 incorporates a unique 17inch wide print width, the length of printing platform is capable to hold two T-shirt trays, hence increasing the production speed. TX4000s unique engineering design offers you innovative concepts to be translated onto cotton based materials and related products. The TX4000 is capable to print high quality vibrant images on cotton based T-shirts in a matter of minutes due to its dual ink supply system. Our TX4000 is manufactured based on the standard piezo print head inkjet technology, therefore it accepts most of the commonly used graphic formats such as Adobe Illustrator, Adobe Photoshop, CorelDraw, Freehand, etc. TX4000 uses 4 color water based pigment ink printed directly onto cotton fabric without pre-treatment and fixing using a flatbed heat press, thus making it the simplest direct textile printing process available in the market.

The Typewriter That Wanted to be a Computer
The Typewriter That Wanted to be a Computer Video Clips. Duration : 12.45 Mins.
Remember these things? Electronic typewriters like this one were once a common sight wherever office equipment of any kind was sold. Eventually, even these things disappeared from store shelves. While there are some being produced today, the sun has basically set on devices of this kind. (However, a typewriter repairman that I once knew--and who still does a good business refurbishing both manual typewriters and IBM Selectric models--once told me that the typewriter is the one thing that nobody uses anymore, until it's broken. There is some truth to this.) I suppose that the idea behind marketing a model like this--which almost could have been a general purpose computer--was to provide a device to those who didn't really want the upkeep, maintenance and learning curve associated with an actual computer system. Something like this unit could almost be described as "Microsoft Works in a typewriter body".
