I like microcontrollers. Often it’s more fun and easier to me to solve some hardware-problem in software, rather than using dedicated hardware.
The problem is it’s usually really a hassle to get a microcontroller for a project running. You have to solder yourself some board, care about power supply, some ISP header, and hope your programmer still works. I’m tired of that, and it seems at least for smaller projects I’ve found a solution now: The Adafruit Trinket.
