You all know the Blinken Button Kit (aka Space Invaders Button). One of the biggest flaws of this kit is that it is not really a beginners kit. But with the help of Jeff (really big thanks for that) I was able to convert it to a perfect SMT beginners kit. The design was drastically [...]

In my ongoing series about cool sensors Interactive Matter presents the AD7746 capacity sensor: What is a capacity sensor good for? You can of course make a device to identify small capacitance (up to 4pF) but that’s boring. Much more interesting is how it reacts to touching. Read on how to connect it to the [...]

Ages ago I bought an LIS302DL from Sparkfun. One of the old (little bit) messed up ones, but still 3 axis accelerometer with I2C output. No external parts. No pain. Fine! Before I go in any further investigation. I need to get it up & running with my arduino (actually an boarduino – but who [...]
