Homemade Power Supply Update

I decided to add a power switch to my homemade power supply when I  found a really interesting light switch at the Habitat for Humanity store in Round Rock. The switch has two buttons, on and off, unlike the single lever of most light switches.

 I also upgraded the FULL BRIDGE RECTIFIER from 800V 8A TO 50V 25A, added more voltage rails, and more smoothing capacitors on the unregulated rail.

  1. I grew up in a house that had those pushbutton light switches in every room! At night you could sometimes see the spark behind the buttons when contact was made or broken.

    Hope to see you Saturday at the Maker Faire in Austin!

    1. Griffin enjoyed talking to you about electronics. Since we didn't have your email, your custom fractals are in the next blog post.
