Fresh hacks every day
[Jerry] has been wanting to put together a whiteboard plotter for some time and just recently got around to building one. The plotter draws pretty much about anything he can imagine on a white board measuring just shy of 2' x 3'. The design first started off with a Basic Stamp board at the helm, which he sourced from another project he no longer had any use for. The Stamp worked for awhile, but … [Read more...]
Oven parts scrounging In response to last week's post about parts scrounging with a heat gun, Hackaday forum member [BiOzZ] decided to try doing the same thing in his oven. It seems to work quite well, but we're wondering if there should be any concerns over the lead content of the solder. Anyone care to chime in? Spill-proof parts holder Have you ever been in the midst of … [Read more...]
The world can be a pretty difficult place to navigate when you lack the ability to see it.

Until now, he has been recording his muscle movements as acoustic waveforms for real-time playback in the bodies of his research partners. This usually requires him to sit beside the subject, … [Read more...]
[EmcySquare] is delving into some hobby-blacksmithing by making his own knives. He needs a furnace to heat the metal, and after trying out a few different forge designs he decided to attempt an electric kiln build. The final project seen above is a box within a box. The outer shell is reclaimed using old computer cases and metal shelving brackets. Inside you'll find a box made from fire brick, … [Read more...]
[Csshop] is setting a new bar for building an inexpensive CNC mill. Not only did he complete his build at a very low cost, but it seems to work quite well too. Check out the video after the break to see the device cut out thin wood parts for a toy plane. The majority of the build uses scrap wood for the body of the mill. The business end of the device is a flexible rotary attachment for a … [Read more...]
SecurID is a two-factor hardware-based authentication system. It requires you to enter the number displayed on a hardware fob like the one seen above, along with the rest of your login information. It's regarded to be a very secure method of protecting information when users are logging into a company's secure system remotely. But as with everything else, there's always a way to break the … [Read more...]
