Fresh hacks every day
[Shahriar] devoted the lastest episode of The Signal Path to looking at energy harvesting chips. These parts are designed to gather energy from non-traditional sources as efficiently as possible. The full episode, which is embedded after the break, is about one hour long. It starts with a bit of background about the nature of these parts, and a brief overview of the wide-range of chips … [Read more...]
Here's a 30 round magazine for an AR15, made just in time to add to the national conversation over things that look scary. This magazine is the product of Defense Distributed who have previously graced the front page of Hackaday with their 3D printed scary bang bang machine. While continuing to work on their WikiWeapon - a gun printable on a home-built 3D printer - the team decided they could … [Read more...]
Any video that starts off with two minutes of motorcycle formation riding has got to be good. If the grainy black and white video didn't tip you off that this was made in a different time the helmetless riders standing on the seats of moving motorcycles certainly would have.

After all, you need to reserve some room to put your feet up when you're not gaming. [Manny Flores] started the project with a … [Read more...]
[Keith] got his hands on a few grandfather clocks. Apparently the price tag is greatly reduced if you are able to get them second-hand. The mechanical timepieces require weekly winding, which is a good thing since you'll also need to correct the time at least that often. But this drift got [Keith] thinking about improving the accuracy of these clocks. He figured out a high-tech way to adjust the … [Read more...]
[Ian Lee, Sr.] made something special for his daughter's birthday party. It's pretty common for girls of this age (this was her 5th birthday) to be enthralled with stories of princesses so he made a blinky princess wand for each party guest. The motivation came when she asked what special thing he was going to do for her celebration. You may remember seeing the LED badge kits that were featured at … [Read more...]
