Solether

Check the website:

http://solether.mkvd.net

check the node Edison code at the bottom of the website!

Check the schematics (the missing part on the top should ve a voltage controller)

Also here's a message I sent to somebody asking via email how I forsee the automated project

Making Solether autonomous:

From a message I sent via email:

The autonomous part as I thought about it a bit, can work like this:

• Solether earns money by giving electricity for people to charge phone / stuff
• you, new user (NEW_USER), add more additional solar panels to Solether, you get paid
• if you connect a new solar panel/power source that gives Solether enough power for a week, you get paid

on the hardware side:

• you have an additional usb port that goes directly to the battery with a wire
• you have a current sensor (detects current) on the wire that detects if and how much current passes from the wire

arduino/r-pi code:

- in the loop:
  - if sensor receives current for a week (during day hours)
    - web3.sendTransaction NEW_USER_ADDRESS (send the funds)

webapp:

(or other app, this is not present, is how I imagine it atm)

• you build a webapp, one screen, that accepts an address as input
• lets you input an ethereum address (NEW_USER_ADDRESS) as payout address
• you have to connect a power source while you register, otherwise the registration will get canceled
• you write a file in the local Arduino/R-PI filesystem, the arduino/r-pi code in the loop reads it and gets the NEW_USER_ADDRESS variable

Schematics:
