Arduino-Powered Laser Clock

Arduino-Powered Laser Clock

Here’s a fun and stylish project you can make from discarded RC car parts and dollar store laser pointers: an Arduino-powered laser clock. Using easily sourced parts, including a Blanda Blank stainless steel salad bowl from IKEA, over-blogger @ Zouliv wired up a couple of lasers to an Arduino to tell time. The left hand tells time by the hour and the hand on the right by the minute. Schematic and suggested hour/minute decal placement are available here.

Now That’s an Enclosure

Now That’s an Enclosure

I imagine Instructables user hellboy started out looking for a subtle, understated case design to show off his single-digit Nixie tube clock called CYCLOPS. Something well-crafted but minimal, and very modern, that would highlight the function of the device while tastefully eschewing decoration for its own sake. And then he thought: Screw that. You only […]

Sketch and Print in 3D from Android

Sketch and Print in 3D from Android

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.

Breadboarding the ATTiny2313

Breadboarding the ATTiny2313

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 […]

Tool Review: iSesamo Opening Tool

Tool Review: iSesamo Opening Tool

“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 […]
