A LEGO Turing machine for [Alan]‘s centennial

2012 is the 100-year anniversary of [Alan Turing]‘s birth, and to celebrate the centennial, [Jeroen] and [Davy] over at Centrum Wiskunde & Informatica in The Netherlands built a Turing machine out of LEGO.

A Turing machine is an extremely simple device, but is still able to compute everything your desktop can. The machine is generally described as an infinite … Read the rest

Fast and easy solder paste stencils

If you’re making your own boards with SMD parts, you might want to get a solder paste stencil. Usually made of laser-cut mylar or extremely thin steel, these stencils allow you to squeegee solder paste onto your board’s pads and make assembly a whole lot easier. [Rochey] needed a stencil for a board he was working on, and lacking a … Read the rest

Putting scores of Arduinos on the Internet with one router

Like many hackers of late, [Rick] has been experimenting with connecting Arduinos to the Internet with a disused WiFi router and an installation of OpenWRT. Unlike his fellow makers, [Rick] thought it would be wasteful to dedicate a single router to one Arduino project, so he used a small, low power wireless module to connect up to 30 Arduinos to Read the rest

Emulating Mac System 7 on an Android device

Over on the 68kmla forums, a website dedicated to old Macs built before 1994, [zydeco] released his Android port of Mini vMac, a Macintosh Plus emulator that puts the power of a Motorola MC68000 processor and System 7 on any computer.

Unlike the original Macintosh, or the subsequent revision that bumped the RAM up to 512 kilobytes, the … Read the rest

Lucid dreaming mask marries economy with comfort

The mask itself is sewn from a child’s fleece blanket. Inside is a … Read the rest
