I have added a project detailing my design for an optoisolated relay controller.  I was looking for a simple way of switching high current DC and AC loads without the added expense of SCRs.  I can use this board to switch on/off lamps, a spindle motor for a CNC machine, or the heating elements on the toaster oven I am using for my re-flow oven project (more on this later).  Excited?  No? Well, go and check out the project anyway as you might learn something or, in the very least, find something that I screwed up on.  If you find the later, please let me know.

Check out the project here or the gallery here.

I have added the first project!  It is called the Hobbyduino Mini or Hobbyduino for short.  The Hobbyduino is my implementation of a minimal Arduino clone using the ATMega328 processor with the Arduino bootloader.  The Hobbyduino board contains a 5V @ 1A voltage regulator.  It also contains a USB-to-Serial device (FTDI) pin header for uploading sketches using the Arduino Ide.  I’ll be adding some projects and tutorials using the Hobbyduino so, stay tuned.  In the meantime, go here and check out the project or go here to check out the gallery.
