We decided it was high time to do some tinkering again today.
That took the form of a trip to our Radio Shack (I know, I know… but they’re the only thing around). We got a “Getting Started with Electronics” book, K got her own soldering iron, and we got a PCB for R’s light alarm. I started through the book with the kids, and oddly enough, it didn’t hold a certain 8-yr old’s attention. The other two got into it. We only covered basic electricity and resistance for now.
Going from a breadboarded circuit to a PCB is kind of difficult, we are learning. Especially when you neglected to note some of the capacitor substitutions made when building the circuit — the schematic has the ideal values, not what we ended up with. (oops). We have a few things put onto the PCB with their leads bent to hold them in place, but nothing soldered yet.
Oh, I forgot the most important purchase. A pair of “Helping Hands”
