Using Archaic Technology!

Since my nephew turned one this year I wanted to build him a simple boost circuit for his birthday. As I've done in the past, for a few friends, I build the circuit on the actual day of their birth so they and the circuit share the same birthday. Typically it's just a simple LPB-1 or a treble boost, nothing too complicated as I'm simply building these mostly for non-musician friends as keepsakes. For little Erik I decided to build him a LPB-1. Maybe someday he'll want me to custom build him something a bit more complex. Heck, maybe by then I'll be building guitar amps too. Who knows!

The LPB-1 being as simple as it is, I didn't want to break out my soldering station and make a big mess, as today was a rainy day, making getting outside a fool's errand. Instead I dug through a little toolbox under my bed and pulled out an old RadioShack 15 watt soldering iron I had barely used before. I found it at the outlet years ago and figured it may come in handy someday. Little did either of us know it would be about ten years before it came in handy, but come in handy it did!

This thing takes forever to warm up, but once it's ready it put plenty of heat into the board and the component to make pretty decent joints. I can't say they're perfect, and sometimes the solder creeped through the hole and onto the actual component being soldered to the board below, but all in all this was a fairly good experience. The tip is conical, which I'm not really familiar with as I prefer a more angled, chisel type, like on my soldering station. Even so, I still have to say this little blast from the past did a decent job.

The joints are a little blobby, but they seem solid. I have to say building the circuit for my nephew, and using the old RadioShack soldering iron made this one of the more enjoyable builds I've done in a while. I probably wouldn't want to use it for anything wildly complex, or high component count, but at least now I know for smaller builds, or maybe even troubleshooting, modifying, or repairs this soldering iron is wholly capable. Now if I could find the chisel tip I like somewhere I think this soldering iron would get a lot more use than it currently is.
