Fresh hacks every day
Want to take back control of how your digital audio files become sound? One thing you can do is to build your own digital to analog converter. This one is made from discrete components, centered around a resistive ladder. Yes, there are a couple of integrated circuits in there which are used for demultiplexing the incoming signal but the … Read the rest
The video above is the final working DIY Segway from [sb-scooter]. The website and build log don’t have a lot of information at the moment, but you can still gawk at several pictures of the construction (and a picture is worth 1000 German words).
For those looking for the nitty gritty, with some quick math we figure its two 500 … Read the rest
[James] has been refining a method of negatively etching metal with a laser. He had been using a product called Thermark which is designed for this process, but it’s quite expensive. He found that paint designed for wood stoves works just as well. To prepare the surface he bead blasted it and then cleaned of the residue and finger … Read the rest
[Bart] managed to get his hands on a Macbook Air for free. The catch was that the monitor hinge was broken and the laptop wasn’t in too great of a condition. Rather than scrapping it or using it as a cake cutter, he decided to turn it into a keyboard PC. By removing the internals he was able … Read the rest
[Jim] was the happy recipient of 11 non working Itona VXL thin clients. The units he received were 800Mhz CPUs with 256 MB of Ram and 256MB of storage. None would power up. Upon internal inspection, he found a common theme. Leaky bulging capacitors in the power supplies. Since these came with custom 50W power supplies, he opted to simply … Read the rest
An Arduino with 40 lines of code, a temperature resistor, and servo are all that’s truly needed to save some dough with this thermostat by [Peter Hamilton]. LEDs and a potentiometer are added as well to help set and read the desired temperature. With or without said additional parts, the hack is still ridiculously simple and we’re wondering why we … Read the rest
