In the shackspace the legacy 433mhz PIR Motion Sensors got finally replaced with PIR sensors directly on the existing esp8266 temperature sensors.
Than also means that the 433 is now free from local interferences and our Funkamateure should not have loud interferences on the band anymore.
The temperature and motion infrastructure is now completely integrated into G.L.A.D.O.S. and can be used for your crazy automations.

Reclaiming Copper from Sodium Persulfate #4: 6B Pencil Lead Anode
As previously noted I've decided to give softer sketch pencil leads a try.
It looks like the electrodes are more efficient and a bit more stable. I've also noticed that the solution seemed to have taken on a lighter blue color and the copper cathode seems to have gotten thicker. In principle it seems to work! However, the thicker anode too started to disintegrate after a few hours at 2 to 2.1 V.
It's time to go back to the drawing board and see if it would make sense to get either a properly manufactured graphite or coal electrode or even go all out and get a platinum one.
Reclaiming Copper from Sodium Persulfate #3: Bigger Graphite Anode
I tried scaling up the graphite anode by connecting several sketch pencil leads together.
I've done this using single strands of stranded copper wire to weave and knot the individual pencil leads together. Once tightly woven into place I've finalized everything by adding generous amounts of solder.
With regards to being able to use higher voltages this was no help (of course) and the pencil leads still disintegrated.
What I've learned:
Fellow hacker reloc pointed out that the softer a pencil lead, the more graphite it contains. I've picked 2H leads for my tests so far and will switch to 6B leads (the softest I could find at short notice).
What is going into solution depends on the voltage applied (potential) and which materials of lower potential are still there (if available, the lowest energy bond breaks first, even with high voltages).
Documented potentials (see: Pauling electronegativity) are usually defined for platinum electrodes. If you're using something else, you have to apply a correction value. Also thanks to reloc for helping out with all the theoretical science behind the experiment!
