Texas Instruments is now sampling to its third-party developer network the 0.47-in. TRP Full-HD 1080p chipset—the smallest TI chipset capable of generating brighter, more efficient full high-definition projection displays from small form-factor electronics. The chipset is based on DLP Cinema technology and employs the DLP4710 digital micromirror device to deliver sharp, clear images in a […]

A while back I built a simple constant current electronic load using an aluminum HDD cooler case as the heatsink. While it was sufficient for a few amps’ load under low voltages, it could not handle load much higher than a few dozen watts at least not for a prolonged period of time. So this time around,
