Folks over at House4Hack in Johannesburg are developing an app, called Paint3D, that will allow you to sketch and print directly to a 3D printer from your Android device. Their app allows you to create an extruded polygon mesh that’s then converted to GCode, stored on an SD card, and fed to the printer. Their goal is to create an easy to use 3D tool that does everything from the Android device.
John “johngineer” De Cristofaro wrote a great tutorial on building an ATTiny2313 prototyping board. I created it because I use the Tiny2313 a lot, and I was tired of wiring up all of the above each time I wanted to work on a new circuit. Some things, like ISP headers and ceramic resonators, are not […]
“Spudger” is a word well on its way into the limelight. Originally, “spudger” seems to have referred to a particular, fairly specialized implement described by Wikipedia as “a wiring tool used for poking or adjusting small wires or components, generally in the electronics and telecommunications industries.” But these days, “spudger” seems to be more commonly […]
Rick asks: I race homing pigeons for a hobby. Motivating them to come home quickly is very important. I want to simulate the random chipping (clicking / egg movement) associated with a hatching egg. I already have plastic pigeon eggs that separate in half like a plastic Easter egg to put this device into, but I don’t know where to get the device. Any help would be appreciated.
Developed during the heydey of the telegraph, the Lineman’s splice is designed for connections that will be under tension. It is commonly claimed that, properly made, a Lineman’s splice is stronger than the wires of which it is composed. In any case, it is a time-proven method, and, coolest of all, one of NASA’s Required Workmanship Standards. To wit…
Fourteen-year-old Lego hacker Leon Overweel built this impressive Lego Mindstorms NXT printer, AKA PriNXT. PriNXT has three motors: two control the X and Y motion, and the third lifts the pen. The first motor, the one in the middle, is very straight forward – it has two long axes coming out of it that connect […]
The Z1 isn’t even supposed to ship until April, so it’s all just hype right now. But it’s working on me. Will be curious to hear what the early adopters report. [Thanks, Phil!] HP Z1 Workstation
