The ball is quite dirty / oxidized. I'd like to see the debouncing code to make this one work properly ;-)

I couldn't get hold of a precision shunt resistor, so I had to do with this 10% 5W one here. It didn't turn out too bad at all. This one doesn't affect the current displayed on the power supply's display (the display measures the current itself), but the current set-point in the opamp feedback loop. I have a schematic, but it is not quite matching the PCB revision I have, so I couldn't instantly figure out which pot to tweak to compensate for small deviations. Reverse engineering a schematic from a given PCB sucks. I compared the current set on the power supply (via a keypad) and the current measured by a good multimeter and it wasn't off by more than 5% worst case. That's good enough for me right now.

Can they be stopped, or will we have to die miserably ? A scene from the movie Downfall has been updated with soccer related subtitles. Although the original content was not funny at all, this definitely is hilarious. Who would have thought a mentally challenged vegetarian hobby painter would make such a good comedian. www.youtube.com/watch?v=z-Ln_rqPpPk

Something I don't want to see again - EVER.

At last! I've been waiting for this quite a while. Now I need to see if it sticks to PCBs well enough for my purpose.

I didn't eat it. It hat unwisely chosen to glue itself to a concrete wall in direct sunlight. I removed it and another one of its species and administered a few drops of water just in case. This one was moving happily, the other one, well... did not. They both were placed in a shady place underneath shrubs.

The image was processed with The Gimp. I applied a 'selective gaussian blur' with a radius of 15 and max-delta of 16

Unfortunately most of the time you just don't look up.

Amazingly low-tech.

I can't count anymore how often I've left this one on and killed my car's battery. It is the ONLY light that doesn't come with a warning buzzer ;-(

The green LED was just too weak.

NE555, R,C. 50% duty cycle. The one shown here was blinking at 2.9kHz. As it turned out the capacitor was 220pF, a factor of 1000 too small. It was replaced with 1µF. Now it blinks at about 1Hz.

Now with a much brighter red LED.

Arrrrr...
