Author Topic: Enclosure for tiny project  (Read 455 times)

I'm fixing to build a handlebar mounted PTT switch for my motorcycle. I've got the switch and the handlebar mount as well as the cable to connect the switch to my radio (Yaesu FTM-10R/E). Yaesu recommend a couple of 390k Ohm resistors in the circuit. I want to do this with a circuit board; I don't want to try and solder the resistors directly. Is there a tiny (because it's two resistors and a few wires) enclosure / circuit board you'd recommend? It should be waterproof as well.

AFAIK you can still order small circuit boards with holes from Radio Shack.  I still use them for projects.  Requires point to point wiring that I use #30 ga. Kynar wire wrap wire.

Find someone who does 3D printing.  They can produce an enclosure tailored to your needs.

What I did for my handlebar controls was to install the switches (up, down and PTT) inside the existing light/clutch housing.  What I'd do with your resistors is to either make a potted "blob" inline with the cable somewhere protected, or inside the plug that goes into the radio.

I'd probably put all my parts on a perf board, and then drown it in a large blob of silicon.
At least it's super cheap and you probably have all the materials in the garage right now.
