Hey, I would like to know where the PCB EAGLE files of the VFD clock are, as I'm going to build this project, but I don't find them. There's a pdf file with the explanation of the clock assembly, but it doesn't include the PCB files. Could someone help me with this? I'd appreciate your help

Hi mr_groll, Thanks for taking interest in my project. Yes I tested it for a small 25 KW project of our township roof top solar PV panel. The 30 nos. panels worked well without problem. I run 4 wires inside a shield. Two wires for 12Volt DC supply and two wires for the CAN signals. It worked well during the test periods of 1 week. In the next phase I'm going to do a bigger testing with a 50 KW solar pannels. There I'm going to use 8 wires [4 as stand by for future use] Bye bye. Bera

Good evening. There are good websites about DIY lava lamps, with various recipes to have 2 immiscible fluids. Some crazy people use water and some fuel (to be heated around 90°C, sic !), then the best solution is to use water and wax, but since the wax density is ~0.7, it must be mixed with some heavy solvent, like tetrachloroethylene... With also a drop of dishwashing liquid to adjust the size of the wax bubbles. To be done at established working temperature. I did it and it works fine. Maybe other solutions could be found that work at a lower temperature. There are sealed plastic deco objects with such a couple of fluids inside, but I don't know what it is. And would such fluids behave as lava, this is not sure. Then the goal could be to create new original lava lamps this way (the creative way), or to convert existing ones once the light bulbs they need have been banned, what should happen soon. This is the main goal of this project, and actually the most electronic part.

Dear Johannes, thank you for your comment. We have recruited 250 schools now and mushroom collecting will happen during the autumn. The samples will be analyzed until and beyond Xmas 2018 with hopefully first publishable results early 2019. They will be certainly announced on the project website My colleagues prepared a movie to illustrate the scope of the project, see the link to the Youtube video. Regarding extensions of the software mentioned in the text (the summer project), I will  place a pointer in the comments to the project.
