  • Project Files: Tachtastic – AVR Tachometer

    Project Files: Tachtastic – AVR Tachometer

    On demand of a site-visitor (Mohsen) I have uploaded all the relevant files that I had for the project Tachtastic: AVR Tachometer, you can download and view them. The files are more than a year old and show how I coded back then and were not meant for uploading – but now that I have […]

  • Phase and Integral Cycle AC Power Control with Arduino

    Phase and Integral Cycle AC Power Control with Arduino

    What you see above is a project made for my Power Electronics Course, last term, finally completed and submitted. It is an AVR based board having 2 optically-isolated TRIACs for AC Power Control and implements both Phase Control and Burst Fire Control on each of the TRIACs. Controllable by an NEC IR Remote, shows status […]
