Ausgehend von den Erfahrungen im eigenen Garten und angetrieben durch unseren Wunsch, einen tieferen Einblick in die Vorgänge der Kompostierung und Humusbildung zu bekommen, sollen die folgenden Seiten das Thema Kompostierung näher beleuchten, zu eigenen Kompost-Projekten anregen und Anleitungen sammeln.

The electronics and software detailed here measures quantities related to DC electrical energy production from micro-renewables. Including: Voltage, Current and Power.
Do-It-Yourself Book Scanning is using cheap, compact cameras* and Free software to scan books quickly and efficiently. DIY Book Scanners can be as simple as a camera and a piece of glass [PDF] or as involved as the Instructable that brought our community together [PDF / Vimeo]. We've come a long way since then. We have GPL-licensed laser cut designs, aluminum designs, and detailed instructions for beginners. We have built hundreds of scanners and freely shared thousands of design improvements.
The EnerJar is an easy-to-build device that accurately measures the power draw of electrical appliances.
schematic may look complicated, but the EnerJar's electronics are actually quite simple. Power is voltage times current, so we must take these values and provide them to the PIC as inputs, so that it can perform the calculation.
