The power part has been finalyzed with a 317T regulator from the solar panel to the supercaps. Since it seems to work I will make a small copper board to make it look a little neater.

I tried two supercaps i series, 10 and 15 F. They could keep a 20 mA 3 volts load going for 6 minutes. I will probably try to arrange it so that a small amount of sun will keep the duck awake for at least 30 minutes.

The tiny engine is now epoxi glued onto the main bracket. I will try to find a suitable cylinder to protect it from water.

I'm not very experient (understatment) with mecanics, today I beleive I made some huge progress by bending a small piece of aluminium. I still have to glue the solar panel and make some kind of waterproof arrangement for the duck engine.

I programmed one of my old msp430f2013 and had quite some problems with the output levels.
The low level did not reach below 0.8 volts.

I discovered the cure was not to enable pullups on the outputs.
I have been living with this error for 3-4 years.
