Portable Gaming

Posted on March 4, 2014 by e8johan

The Arduboy platform is heading for kickstarter. It is a creditcard shaped gaming platform featuring capacitive buttons, a small OLED screen, speakers, battery and a barebone Arduino (atmega).

I think that this looks great for gaming, but can think of a gazillion more applications. Just having access to a really low cost, customizable interface like this can revolutionize user interfaces to many low end embedded projects.

Schematics On-line

Posted on February 27, 2014 by e8johan

Schematics-Logo-Horizontal-Light_GreyOver at schematics.com you can find designs and share your designs in an online community. This can be a handy resource for finding reference designs. An interesting detail is the contribution from semi-conductor manufacturers. For instance, NXP are contributing designs to the site.

Retro Flapping

Posted on February 25, 2014 by e8johan

I guess very few have missed the Internet phenomena Flappy Bird. It is a rare occasion when a game is retracted for being addictive.

There are a number of clones out there. According to arstechnica you can run it on your Pebble watch, Nintendo 3DS, basically and conceivable smartphone out there, and more.

More interestingly, according to boingboing, you can also have a go on your Atari 2600, ZX81, TI calculator or C64. This really shows that the gaming experience that you can get from a multicore gigahertz smartphone packing gigabytes of RAM and FLASH can be achieved using a few thousand bytes of ram, a couple of megaherts and an 8 bit CPU.

Of course you can play it on the Raspberry Pi as well!

Open Source Knitting

Posted on February 21, 2014 by e8johan

Being married to a dress maker, this project really resonates with me.

openknitThe people over at OpenKnit have created an open source knitting machine. This takes home production to a new level.

I get the impression that open source support for making garments really is growing these days. For instance, Valentina is an open source pattern making program.

To complete the picture, do pay a visit to doKNityourself, a site aiming to be the Thingiverse of open source garments.

We’re back!

Posted on February 21, 2014 by e8johan

CC-BY http://www.flickr.com/photos/jenorton/2229437427/So, it has been a while since the last update on this site. There have been loads of reasons for this – lots to do at work, having a second kid, trying to write a book, etc. All positive problems in my world resulting in fewer posts here.

Recently I’ve missed this site, so now it is time to start pushing again. I hope that you will enjoy the ride!

Arduino Pong

Posted on July 1, 2013 by e8johan

componentsWhat is the first thing to do when you have video out on your microcontroller? Some say Tetris, other say Pong.

I won’t lie – it’s unlikely your daughter will be giving up her Nintendo DS, and this isn’t going to provide hours of fun for the whole family – but it is an awesome and easy project to improve your Arduino coding.

We’ll make two basic controllers, and the video will output to your TV through a standard composite video cable.

Facial Recognition using RPi

Posted on June 19, 2013 by e8johan

The Raspberry Pi blog just mentioned Pierre Raufast‘s experiments with OpenCV and the RPi camera module. He achieves facial recognition with multiple targets at ~8fps, which is kind of impressive given the limited processing power of the Raspberry Pi. All the steps needed are described in his seven parts tutorial.
