One thing we’ve encountered in Weekend Projects, our weekly beginning electronics series is that there are several ways to fabricate the same circuit. Working from a schematic, some may choose to quickly test a circuit on breadboard, while others may opt for a more-permanent perfboard solution. And some will want to etch their own PCBs – a very rewarding experience. Since we’ve now worked with every type of through-hole circuit board, I thought it would be fun to issue another challenge. It’s quite simple: build any of our board-based Weekend Projects on a different type of circuit board than the one originally demonstrated in the project. For example, build a perfboard project on stripboard, transfer an etched circuit design to breadboard, and so forth.

The first dozen challengers to write in with pictures of their circuit board mods will receive a coveted Maker’s Notebook. Applicable projects include the Whack-a-Mole Game, Wearable Light Organ, 555 Timer Ball Whacker, Light Theremin, Treasure Finder, and the self-synthesizing Luna Mod Looper. This challenge will run through the end of the year, or until we run out of notebooks, whichever comes first. So get making and send us your story!

  1. Here’s my version of the light theremin on a perfboard (it was originally assembled on a breadboard):

      hi Kendrick,
      Super! I just sent you an email earlier – will await your reply.

  3. Here is my perfboard version of the 555 Light Theremin.

    I liked the solar theremin in the makershed, so I squeezed my light theremin into an Altoids Smalls tin.
