Fresh hacks every day
[lucassiglo21] let us know about his finished 3 axis CNC (Translation via Google). While home CNCs are nothing new, we really liked this masterpiece. The CNC is entirely custom, from the electronic control boards (connected to a PC via parallel port) to the physical mill (with an end result of 30x30x15cm workable area). Our favorite part is the use … Read the rest
We’ve seen a glut of time-keeping projects lately. We guess time was the original motivator for technology so we’re okay with it (but we’re not calling ourselves Clockaday quite yet). This clock, or more appropriately this timer, is a homemade hourglass that [Andrei] put together. The finished look is simple but he put some real time into its production.

Drilling precise grids without a CNC machine can be tough to pull off. [Ookseer] has come up with a nifty method for dilling aligned holes with a drill press. He uses a right-angle jig on a Dremel drill press with stacks of business cards as spacers. The same number of cards is added between the substrate and the jig … Read the rest
[Contraptionmaker] ran into a problem when putting plastic insulation over his windows during the winter. When you cover the windows from the inside to prevent drafts, your access to the stick that opens the blinds is cut off. His solution was to build an automatic blind opener from a cordless drill. He started with some motors he had around the … Read the rest
A decent drill press is a crucial tool for an electronics lab. We use our drill press to make holes in our own circuit boards, and tap or break traces on existing circuit boards. We’ve used a lot of tools to drill circuit boards — power drills, power drills in “drill press stands”, and high-speed rotary tools — but when … Read the rest
[Alexander.m] shows us how to do a major overhaul on a cordless drill, replacing pretty much everything but the case. He needed some more power, but found the price tag of the bigger drills to be prohibitive. He opted for a more hacked together approach and used a 24 volt 1.4 hp hobby motor as a drive. He had … Read the rest
[yellowduck] took some fantastic initiative with this home made PCB drill press. Many people have a rotary tool already. Just add some scrap wood and four hinges. The drill press isn’t perfect; it pivots a little as it lowers. This shouldn’t be a problem for drilling printed circuit boards though. The PCB should be thin enough for the pivot … Read the rest
