Fresh hacks every day
How many of you have started playing Jenga, and thought, "If only I had a pistol that would punch the blocks out violently for me, that would be much more fun?" Your presumed request has been answered with the [Jenga Pistol 2]! There is also the [Jenga Pistol 1], which would be impressive if the second one wasn't already made and functioning! There's a great video of the second one working after … [Read more...]
Here at Hackaday, we’re all about repurposing old items you no longer use. Reader [Liquider] wrote in to share his latest creation, a coil gun built from an old Airsoft pistol. He removed a handful of components from the pistol and installed a 800 uF/300V capacitor inside the grip.

[Greg] took an old garage door opening fingerprint scanner and wired it into a half broken keypad based pistol safe. While he did have some issues finding a signal that only … [Read more...]

A wall was built down range to use as a projection screen. Accelerometers mounted on the drywall report vibration data from the bullet strike which is used to triangulate its location.

[Daniel] had to have runaway in his mind when he built this coil gun. It's hand held, holds 14 42 gram rounds and can propel them at speeds of 110km/h. Of course when it is battery powered, you have a 90 second warm up time between shots. It can also be used while plugged into a wall socket, which reduces the charge time to roughly 3 seconds. Great job [Daniel]. [via engadget] … [Read more...]
