Fresh hacks every day
Another broken LCD TV came [Steve DiRaddo's] way. This one had a broken backlight that he wanted to fix. He scrapped his LCD light table in order use the inverter. The two televisions were not the same size, nor made by the main manufacturer, but backlights all operate under the same principles. Using an inverter from a bit larger model meant it would have enough power to illuminate the lamps but … [Read more...]
Want to do quick and accurate focus change with your DSLR? Here's a discussion thread covering dirt-cheap solutions. It starts with a broccoli rubber-band and a couple of zip ties. That being a bit chintzy, the more popular build seen above uses a hose clamp, rubber band for padding, a drawer pull, a nut, and some threaded rod.

Some are just propped up against things, some have had box hinges glued to them and some are just waiting to die slowly from non use. [Jakob] has a nice neat conversion where he basically made a tablet. We've seen that … [Read more...]
Wow, that title is flamebait... but give us a chance to explain. [George] wrote some code for the Arduino that allows it to program another Arduino. You may be thinking to yourself "this has already been done". In a way it has, with the AVR ISP programming shield. But once the code has been uploaded to the Arduino, you don't need a computer to program the next chip. This concept turns an Arduino … [Read more...]
