**Capacitance meter with a current source to measure C from 1 pF to 400+ mF range**
At the beginning of a huge thank to you for the Dillon from EasyEDA Team for helping to make this documentation. Without him, t...

**Open Solar Energy Diverter**
This project have the aim to divert not comsumed electricity produced by photovoltaic panel to water heater to keep energy produced in the area of usage.
This project is base on idea from [http://energie-autrement.blogspot.com/p/plans-eolienne.html]...

Using 555 as a multivibrator we can measure the capacity of the connected capacitor.
At all times, the 555 charges to 2/3 VCC and discharges to 1/3 VCC the connected capacitor, supplying a rectangular signal at the output in accordance with the capacitor charging and discharging cycle....
