Looking for a super geeky card to make for that special someone? You could always buy a Hallmark card but let’s be honest, that’s just being lazy. In this post I’ll show you how I made my own for my partner’s 24th birthday.

Hit past the break to for a video of the card.

Stream music to your car with a USB powered Airport Express

Stream music to your car with a USB powered Airport Express

Posted by on Oct 6, 2012 in Hacks | 0 comments

The newer Airport Express’ are a quick 20 minute hack away from being able to be powered by anything giving out 3.3V or higher. So if you feel the need for a USB powered Airport Express in your car that you can Airplay music to, read on.

Why would you want to ever Airplay music to a car? Well not all cars have A2DP, which is a total car making scam. Maybe you’d like to play music from your laptop, or just plain hate auxillary cables all over the car. In any case, its quite easy to swap out the standard power supply form an AE with something more car friendly. Sure you could hook up the AE to an inverter, but apparently the alternator gives you a hiss on the sound quite often from poor grounding. Ok. Enough with the why. A simple “Because I can” would have been good enough.

ATTINY85 – Good things do come in small packages

ATTINY85 – Good things do come in small packages

Posted by on Sep 27, 2012 in Hacks, Reviews | 0 comments

The ATTINY85 is a gem of a microcontroller. Its the “Nifty Fifty” of chips: cheap, small and versatile. This 8pin package is not the most powerful thing on the block but for good enough for most hobbyists and there are a million and one tiny projects that this is fully capable of running. And at $1-$2 a pop, its really hard to beat. Its almost disposable if you order a bunch for all your random little projects. It does take a bit more setup than an Arduino to get it running, but there are lots of easy to follow tutorials on the internets for people to follow. If you have an Arduino sitting around, its quite easy to use it to program the chip as well.

Most of my hobbies don’t get along with my bank account so its nice to find the little things that can be so interesting. So pick up a few and whether you make something useful or just plain silly, rest assured, it’ll be fun!
