A few days ago I visited my parents. The main purpose was to ‘deposit’ my new Lecroy WaveAce224 DSO. I bought it as a gift for myself, but I haven’t fulfilled all criteria to receive the gift yet. Therefore my parents are ‘guarding’ it for me until I’m allowed to have it. As Lecroy were [...]

I was having problems with the “led ring” boards. Their internal oscillators were not ticking with the same speed and required constant re-syncing. I tried to improve the situation by recalibrating by adjusting the OSCCAL registers. Recalibration can be done quite easily with an oscilloscope. Either assuming that the _delay_ms() routine is reasonably correct for [...]

Well… sort of.
I finally got the PCBs from sparkfun! Almost 6 weeks, 9 days only for the “air mail” letter to get to me. Maybe my “dear friends” at the customs office were “busy” again.
Unfortunately my request to change the design I had ordered with an updated one seems to have gone unheard. Even [...]

For quite some time I have 19 SMD RGB LEDs sitting in one of my electronics boxes. It used to be 20, but I’ve ruined one while trying to solder it to perfboard. They are 3 single LEDs put into one package, no common anything. The board contains an ATmega168 chip, a few resistors, capacitors [...]

Not having the right tools is such a pain.
The modification I’m planning to do requires cutting 72 round 35mm holes into the white plastic foil that forms the Ikea SAMTID’s “head”. I tried to do that with a scalpel, but failed miserably. Getting holes in there is not a problem, but getting them to be [...]
