Fixing a dying power supply…
Sid on the Hacks site writes up a good simple how to/tip – “My LCD display wouldn’t come on, it would just flicker. The LED on its external power supply was steady on when it wasn’t plugged into the monitor. When I did plug it in, the LED blinked at the rate of 2x per second. Measuring the power coming out of this supply using my multimeter, I saw that the power level wasn’t steady — it was pulsing slightly (about 2x per second). This was while unplugged from the monitor. Found a new power supply on eBay, and now everything’s fine.” Link. On a related note, the RSS feed on hacks site is awesome.

Zerocool60544 in the AutoIT forums writes about a PC control project using a browser or cell phone “I use lego mindstorms’ motors, they don’t a lot of torque but I geared them down to be a little slower but stronger. The water bottles are the counter weights so their is always tension on the line. There are two motors on either side. (one near the closed position and one near the open position).” [

Weber decided to start construction of his house by building a homemade solar water heater… “It took a lot of time and sifting, but I was finally able to devise a simple and inexpensive water warmer that I knew “us regular folks” would be able to build. In fact, my design involves only three steps: First, build a glass-covered wood “hot box” to catch the sun’s heat. Second, install a manifold of copper water pipes–inside this collector box–so the gathered warmth will heat water. Third, hook the outlets from the manifold to a storage tank (this container should be set above the heat collector) so the thermosiphon principle will move water from the collector to the tank.” Thanks Star! 
Surj writes “Today I presented the Tux-Phone idea at the O’Reilly Emerging Telephony Conference in SFO. An open cell phone platform named tux-phone. Three important disclaimers: It is not a novel idea. People have thought and written about similar equipment. We just started building it. The engineering process is fairly straightforward except for finding the right parts and putting them together while keeping it small.” 
Using some plastic and a toaster you can make your own PSP stand, JavaMoose writes “I decided to make a simple little stand for the PSP. Handy when watching videos, and it lets me have it connected to external speakers and the charger – while on the stand. It is very simple to make, and only cost me about 20 minutes and 25 cents worth of plastic.” [
