The Computer Without A CPU

[Jeff Laughton] was contacted by a customer that was interested in adding some automated functions to a printing press. Before eventually settling on a microcontroller for the job, [Jeff] went old school and started looking at logic gates, counters, and flip-flops. This lead him to the Motorola 14500 industrial control unit, a minimal processor with only 16 instructions. After a few ˜back of the napkin™ sketches, he came up with an extremely minimal computer that doesn™t use a microprocessor. It™s an interesting design notable not only for its electronic brevity, but also because it only uses one instruction.

Blinky LED Necklace That Actually Looks Chic

[Agy] a fabric hacker in Singapore has made a chic light sensitive LED necklace, and written up the tutorial on her blog  Green Issues by Agy. The lovely thing about this hack is that it doesn™t look like a breadboard round her neck, and most of the non-electronic components have been upcycled. [Agy] even used Swarovski crystals as LED diffusers for extra bling.

Using a LilyPad Arduino with a light sensor and a few LEDs, [Agy's] circuit is not complicated. She seems to be just branching out in to wearable tech, so it is nice that she learnt to ¦ Read the rest



Sci-Fi Contest Roundup: Stargate

The 90s were a remarkable time for Sci-Fi movies, in that there actually were sci-fi movies, and not sequels to a reboot of yet another comic book movie. One of the breakout hits from this era was Stargate, the film and three syndicated television series. With a corpus this large, a few Stargate builds made it into our Sci Fi contest, and from the looks of things, they™re pretty cool.

The Edinburgh Tool Library at the Edinburgh mini Maker Faire

You can't own every tool, and even if you're lucky enough to be a member of a hackspace or makerspace, you can't take them home if they do. Which is where the Edinburgh Tool Library comes in, it's a new charity that not only wants to lend you tools, but teach you how to use them.

Flexible Arduino Sure to Be A Hit

 

Wearable, lightweight hacks have long been dominated by the Lilypad. This will probably change with the introduction of the Printoo. Using printable circuit technology, the Printoo takes a modular approach to enable hackers, makers, and engineers alike to construct flexible circuits that can be put on almost anything, including paper!

Powered by the all too familiar ATmega328, the Printoo core module is fully compatible with the Ardunio IDE. The modular design enables functionality with several other printed devices including displays, batteries, sensors and even LED strips to make many different projects possible. One of the most interesting modules ¦ Read the rest



Filament Extruder Pumps Out 1kg/hour!

3D printers are awesome, and while the plastic filament may not be as much as a rip off as printer ink (yet), it™s still marked up at least 500%! If you really want to break free, you™re going to need your own filament extruder.

ABS, a typical printing material, will run you about $30 USD per kilogram. Don™t get us wrong, that will go a long way ” but did you know ABS pellets (technically processed MORE than filament) can be as cheap as $3-4/kg?

What if you could buy the pellets, and make your own filament with them? If ¦ Read the rest



Make a 3D Scanner for 60€ Using Old Hardware

[Till Handel] just put the finishing touches on a paper he wrote about how to build a cheap 3D scanner ” mostly out of spare parts.

Using parts from old printers and notebooks, he™s cobbled together this rather rough-looking laser scanner. But don™t be fooled by its looks! It™s capable of scanning 360° around itself at distances from 0.3 “ 5m, making it an excellent candidate for scanning rooms.

It uses a line laser and a webcam mounted on an arm driven by a stepper motor, which looks like it™s out of an old optical drive. An Arduino Uno and ¦ Read the rest



The Invention of the Aerobie & the AeroPress #makerbusiness

The Invention of the AeroPress. Among coffee aficionados, the AeroPress is a revelation. A small, $30 plastic device that resembles a plunger makes what many consider to be the best cup of coffee in the world. Proponents of the device claim that drinks made with the AeroPress are more delicious than those made with thousand-dollar [¦]


Genetically Engineered Trees Make Paper and Biofuel More Easily

Researchers at UBC have created a tree with a modified polymer that allows for easier paper making and biofuel production. This achievement means reduced chemical use, fewer environmental impacts, and less energy needed when these trees are used for the purposes of paper and biofuel production. From UBC News: œOne of the largest impediments for [¦]
