Here is the list of projects and related documents for projects that are completed. These may not be the latest version, as there are many revisions going on all of the projects. But you can definitely build these projects and get a working model. All project files are provided in their respective project page so that anyone (yeah! you) can build them themselves. Also you can purchase the materials for the projects from us. We’re not a dedicated seller, but if you purchase from us, or you like a project and donate some funds, those will help us continuing experiments and doing new, and better open-source projects.
For the loyal donors: If you’ve donated for purpose of development or update of any specific project you were interested, you can avail 25% discount on product price for the project, if you buy from us after the project completes.
Atmel Atmega8 based Voltage-Ampere meter. It’s a handy one to put in your own power supply unit. This will show the voltages and current passing through the output in amperes on the attached LCD.
Here the energy coming from a solar panel is monitored. This project senses the solar voltage, battery voltage and determines whether to charge the battery or not. It also records each data like voltage, current, temperature to an attached SD card for future diagnostics.
