Archives For circuits

Last month I attended Maker Faire Atlanta with other Atlanta Hams where I helped teach kids how to build a very basic circuit with an attention-getting LED.  I blogged about that here.

I wanted to salvage that mini breadboard and I had some Adafruit Perma-Proto PCBs that were looking lonely, so I moved all everything over and soldered it into place.  It turned out pretty well, but I wasn’t so sure by the time I had arrived to the end.

I started by placing the 555 timer directly in the center of the board instead of counting out my spacing to ensure I’d h ave enough room the way everything was laid out.  As it turns out, I did, but I was right on the edge of the board when I soldered the capacitor on.  Had I started one space closer to the edge of the board, I wouldn’t have had enough room.

Maker Faire Atlanta

October 7, 2014 — Leave a comment

In between everything else I had going on this past weekend, I managed a few hours to drop in on Maker Faire Atlanta in Decatur on Saturday to help the Atlanta Hams group teach kids how to build a basic circuit.  The weather was perfect for it and there was quite a crowd of enthusiastic Makers hawking their projects.  I figured I helped at least two-dozen kids (and a few adults) build their very first circuit.

It wasn’t all kids, though.  At one point, I had three very enthralled moms diligently working to build their own blinky while their disinterested kids begged to move on to the next exhibit. 🙂

We selected the Light Sensing Mini Breadboard Blinky which are cheap and easy to build.  At the end of the build, the kids got to take their newly created circuit home with them.  I don’t recall the final number, but I believe we helped around 250 future Makers build this circuit.  I hope many of these kids went home excited about electronics!
