OneOfSix | Hacking the Tassimo single-serve coffee machine | Digital Electronics & DIY | Scoop.it

Like many techno-geeks, one of my favourite kitchen appliances is the coffee machine.  Mine happens to be a Braun Tassimo T1200, which is by far and away thecoolest coffee machine because it is actually a programmable beverage dispensing system.  With it I can make anything from a run-of-the-mill cup of Maxwell House to espresso, latte, cappucino, hot chocolate and everything inbetween.  And with almost zero cleanup.

Pushing Pixels - cliffle.com | Digital Electronics & DIY | Scoop.it

This post is the second in a series looking at the design and implementation of my Glitch demo and the m4vgalib code that powers it.

For the first technical part in the series, I’d like to start from the very end: getting the finished pixels out of the microprocessor and off to a display.

Why start from the end? Because it’s where I started in my initial experiments, and because my decisions here had significant effects on the shape of the rest of the system.

Learn FPGAs in your Browser

Learn FPGAs in your Browser | Digital Electronics & DIY | Scoop.it
PGAs aren’t really programmed, they are configured. Most designers use Verilog or VHDL to describe the desired circuit configuration. Developers typically simulate these configurations before committing them to silicon (a good habit, especially if you ever graduate from FPGAs to ASICs where changes are very expensive). That simulation takes a lot of software you have to install and learn, right?

Crazyradio for Cheapskates | Digital Electronics & DIY | Scoop.it
The Bitcraze Crazyflie 2.0 quadcopter can be controlled by a PC with the Crazyradio USB radio dongle. Unlike the first-gen Crazyflie, this isn't required since the 2.0 works out-of-the-box with Android or iOS as a controller over Bluetooth. However the Crazyradio opens up some fun features like servo absolute position control using Kinect or telemetry from hacked-on sensors. Bitcraze is kind enough to open source their products, giving source, tools, and documentation for the firmware running

Creating a USA Non-XL *New* 3DS Hardware Variant | noodlevisions

Creating a USA Non-XL *New* 3DS Hardware Variant | noodlevisions | Digital Electronics & DIY | Scoop.it

Back in February, Nintendo of America decided to release the *New* Nintendo 3DS following its earlier releases in Europe and Japan. The *New* 3DS is a refresh of the 3DS system, with upgrades such as a quad-core processor, C-stick nub, dual rear triggers (on each side), and face tracking 3D. As with the original 3DS, there are two variants of this system: a pocketable version and a slightly-less pocketable version with larger screens. The smaller model also provides new opportunities in terms of customizability, with removable front and back cover plates that make it possible to change the top and bottom appearance of the console in seconds. There are 59 official cover plates as of writing, and they are pretty neat. The *New* XL, unfortunately, is the same as the old consoles in terms of personalization– there is not much you can do non-destructively besides putting on decals.
