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 [...]

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 [...]

So I started testing how low [...]

I’ve waited for 5 weeks for the 2nd batch of the 64-pixel RGB matrix controller boards. This time I ordered from MakePCB as I wanted to test another PCB manufacturer. Also I couldn’t get gold plated pads from GoldPhoenix for a reasonable price. As far as I can see right now, the boards are of [...]
