Introducing the shacklogger
makefu wants to establish a new process to show off what is happening in the shackspace more easily.
By utilizing log.shackspace.de tumblr account, a spare Nexus4 phone and a QI charger everyone in the shackspace will be able to make a quick snapshot of his finished/WIP project without much hassle and show it to the world.
Just take the phone, make a photo and post it!
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.
