US gov. to hacker: STFU

Feds aim to take out the Bunnie, "father" of xbox hacking. Read more about it on TG daily. Why do several states want to silence chineese men theese days?

Raving Robot urges all hackers to procreate like bunnies to eaven out the field.

Pic related. It's a bunny.

Unconventional gears

I've allways had a feeling my gears wasn't like they were supposed to. This video I stumbled upon tells me there are more ways of making gears than I had imagined. Take a look.

Done some extensive testing of the door opener the last couple of days. And it works fine. Here is an action photo of it, all covered in snow but still doing its duty.

The hardware is my own take on the arduino, witch I dubbed the sketchyduino in an older post. The firmware is loosely based on Robert Carlsens work.

I'll happily write more details of this work, or other projects of this sort if you want me to. Just shout out in the comments!

On the list

Google might have to track those who don't want to be tracked. Er... Make a list of those who don't want to be listed -errr.. How should I put this. According to insidegoogle, google needs a database of the people that do not want to be in the database. Read more about it here.

Hardware debuging

Ran in to some problems with the garage door opener project. I swapped the four button epoxy keypad with a "real" one with 0-9 , "*" and "#". I took precautions for voltage drop over the longer lead, but it still didn't work every time. The relay doesn't connect for 1000 millisecs like the code says, WTF? I think it must be an issue with the power supply, so I beefed it up a bit, and I am testing it now. Hope it works tomorrow morning, after a cold night.

Weatherproofing

Making a keypad to mount on the outer wall of the garage requires some weatherproofing. First I had to add a capacitor to overcome the voltage drop over the 2 meter long lead, and add quite large pull-downs (15KΩ). Now I need to make the whole shebang work in -20˙c, and even in blizzards. This has prooven to be harder than I thought. The relay won't work when it's cold, even though it rated to work just fine down to -40˙c. I'll try to solve it with more power, regulated from a transistor on the out-pin of my controller.

Any tips on outdoor electronics are welcome in the comments!

A few days away

I've been haveing fun with barcode fuzzing lately. The setup is as easy as blinking an LED, so if you play with Arduino, BasicStamp, PICs, mbeds or the like -this is something to try! This post on irongeek is what gor me going.

I'll be away till the 15th, but please stay tuned!
