Make an RFID tag with an AtTiny and a coil

When I stumbled across this blog post, I was sure I have to try this at home. I had some interest in RFID for a while, but the Proxmark was too pricy for me just to play with. So this experiment came just right.

The attiny85’s were difficult to get in Switzerland, so I ordered them from Germany along with an ISP programmer. I think it would also work with other AtTiny’s for example the 45 is available from Conrad. The hex file is just 1.7 kB, so the AtTiny45 should suffice.

It looked similar from the inside as well. So, it is probably really a bifferboard. The pins for the serial console matched, which was even more proof…

The boot messages with the stock firmware look like this:  $ minicom -b 115200 -D /dev/ttyUSB0

Refurbishing our VW Bus camper van

Refurbishing our beloved VW Bus camper van that served us so well on our great adventure in south america was long over due. After lots of offers and some setbacks, it’s finally going to happen before the rust wins.

Last week, I spent two days tearing everything appart.Removing bumpers, windows, lights, mirrors, trims, bike and kayak carrier, fridge… Scratching on every bit of rust I could spot.

Now the pro’s will handle the rust and give it a new paint. And in two weekt, I will put everything back together. Here are some Pics of how it looks at the moment:
