Last bits

The last bits are coming together, piece by piece.

Not being able to extent the meter long lead from the thermocouples I used a plastic food-container as cheap box to mount the TC boards on the backside of the testfurnace.

Last step in the software development get a graphic user interface. The furnace has a micro-controller that preforms the measurements and controls the heaters. The micro controller is connected to the mirco-computer that gives the commands and logs the operation.

After trail and error it seems the furnace will finally get a real KWh meter. From Maxim we got two 78M6613 IC’s for free and Faber Electronics mounted them on the Adafruit breakout boards. It’s a real RMS single phase wattmeter where with a single command you get the used watt’s, precisely!

After the big Arduino one board and the mess that gave in the connection to the UEXT connector on the Olimex boards I ordered a Olimexino-nano

About Egidius Kuhlmann

Reading about peak-oil, overpopulation, “Terra Preta” and biochar in 2009 and after making batches biochar for soil improvement from garden residue, I thought, why not make biochar from corpses. Deeply worried about the unsustainable path 'we' as humanity have taken, I see a future where fossil fuels are scarce, the western economic growth model in tatters, the global temperature rises due to the CO2 concentration in the atmosphere with an growing population reaching billions more humans than is sustainable? Thinking along those paths, the question “how can we dispose so efficiently and with the least amount of energy of human remains” became the starting point.
