Almost done with this l-match #hamradio antenna tuner. I tried to put it into a case since it was a known circuit, which went predictably poorly. After I splayed it out onto a blank copper board (like I should've done in the first place), it became much easier to find the problems.
The final version is in a different case, using a different coil setup, but, most importantly: using copper tape as "bus bars" worked really well. Would recommend as a technique, if you're low power enough.
Attachments:
- A photograph of a disaster of a desk, covered in a pile of mess, with a bit of useful work cleared in. There is a trusdx connected to a bunch of components randomly soldered to a blank piece of copperclad board, going off to some banana jacks on the other side of the photograph. (remote)
- A photograph of the final version, which is nestled into a 3d printed case, with things much more neatly packaged. There are two "bus bars" made out of copper tape that's been stuck to the inside of the case. (remote)
