RFID Candy Box + Twitter



Christmas is coming. The pre-christmas season has started. Sweets everywhere. It doesn't matter, if it's classic chocolate, marzipan potatoes, baked goods or gingerbread: Everything, everywhere! Everything is within easy reach, waiting to be eagerly devoured.
Every year i swear myself, to not eat this much. But every time i lose. Every time I lie on the couch, nearly sick, swearing to do better next year. Not this time. This year i will build some prevention:
A crate, which I have to open with a RFID Token, just three times a day. Haha! Take this! Future me!

Let's do some art. Lightpainting



Writing and painting with light. This idea is not a new one:
You just take a camera, switch it to longtime exposure and paint with a flashlight, or LED, some characters in front of it. This works properly, if you are able to draw. I'm not.
So I just stood by admiring those people, but knew I will never be able to do this. Two years ago, while I visited the 30c3 (Chaos Computer Congress), there were some guys from Blinkinlabs. They sold some bags full LED stripes. I bought on e myself anf found out, that you are able to blink own images with it. But unfortunately mine broke after some days of testing. They are not (very) waterproof...

Arduino: Atmel-Flash-Station



Finally not always using Arduinos:
Every time i nearly finished a project, I'm annoyed about using an arduino again, which uses a lot of space and isn't really necessary. A small stand-alone-controller would totally be enough. While prototyping the Arduino-PCB is a cool thing, but afterwards, when everything is finally assambled, the arduino needs a lot of space, which could be used for other things, like less case.

EMF Detector: Let's hunt some ghosts!



The idea to build an EMF-Detector came while i fucked up my last project partially. While i was soldering the pcb i did a mistake while connecting a wire. This gave me a broken signal of a buttonstate (switching from 0 to 1) switching back and forth. I fixed that, but wanted to know exactly why this happens.

Result: When you don't connect the input of the controller to ground, you are not able to set a solid state and the ┬ÁController starts to interpret everything what he gets. In this case it reads electromagnetic fields. So why not digging further into this and build a gauge to have a look on which devices are having a nice electromagnetic party?
