Usually when an alchemist shows up promising to turn rocks into gold, you should run the other way. Sure, rocket fuel isn’t gold, but on the moon it’s worth more than its weight in the yellow stuff. So there would be reason to be skeptical if this “Blue Alchemist” was actually an alchemist, and not […]
Generally, a digital TV tuner is something you buy rather than something you make yourself. However, [Johann] has always been quite passionate about the various DVB transmission standards, and decided he wanted to build his own receiver just for the fun of it.

In fact, it’s perhaps a task better automated, as [skulkami3000] demonstrates with this robotic build. The heart of the build is a flat platform fitted with a resistive touchscreen panel on top.

For a while, our phones were all getting smaller, then they started getting bigger again as screens expanded to show us ever more content and advertising. The iPhone air is going back the other way, with a design that aims to sell […]
Repairing vintage computers is bread-and-butter for many of us around here. The machines themselves tend to be fairly fixable, assuming spare parts are available and there hasn’t been too much physical damage. Peripherals can be another matter, though. Since they interface with the real world they can have more esoteric problems that aren’t always solvable. […]
Often, we face tedious tasks with no way around them. Sometimes, you just have to grit your teeth and push through. But small tweaks can make the onerous task a bit easier to handle. [James Bowman] sent in his latest quick project that helps him fold small boxes more efficiently. To fulfill orders on his […]
