  • sniffing i2c with the BusPirate

    I received my BusPirate v4 a while ago, but didn’t really use it so far. That’s a cool analysis/debug tool for serial buses such as uart, spi, i2c and the like. For me i2c is the most interesting. From time to time, the communication doesn’t work as it should, and so far, I worked it […]

  • AtTiny Advent Wreath

    An advent wreath in late spring, you ask? Yes, the timing is a bit off, and that’s not just because the coldest spring in ages has not finished yet. While browsing for the topic of my last post, I discovered a nice little one-evening-project: Geeky advent from tinkerlog. I had all the required parts here, […]

  • AtMega breadboard header

    A while ago, I ordered some AtTiny breadboard headers from tinkerlog.com. Unfortunately, they didn’t have any boards for AtMega’s left. The ones for the AtTiny’s are very handy, and I used them whenever prototyping something with an AtTiny. In fact, I used it almost whenever flashing an AtTiny. Many times I wished I had one […]

  • switching the christmas tree online

    The first time I got interested in home automation, was when browsing the arduino libraries. That was all about X10, which communicates over power lines. There are switches that can replace the regular light switches and are pretty cheap in the US. If you want such switches here in Switzerland, you’ll be surprised how expensive […]

  • LED debugging the stereowrap hardware

    I found out earlier that 5V is not enough to drive the shutter glasses. With my breadboard setup for stereowrap, I fed 12V to the op amps from an external source. Now that I moved the thing to a strip board, I added a step up converter that generates 12V from the 5V available on […]

  • 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 […]
