Step 2Parts
Depending on your access to materials, this can cost very little, bordering on nothing at all.
In the image, the parts used are laid out. Don't worry if you can't see the scrawled biro, I'll go through everything as we go along.
First, you'll see a rather dead looking watch, this cost AU$10 new and has been sitting in my junk box for years. We'll only use the straps and the little sprung rods down in the bottom right.
The transparent plastic dome is-was a scoop from a protein shake (yuck) with the handle cut off and filed smooth. The closer to round this is, the more accuracy you can get in your dial.
The white circular piece of plastic is exactly that. This one is acrylic cut with a hack saw and a rasp (call it a workout or find a laser cutter). This will become the base plate.
The pen-scratchings are plans for a mount to attach the straps to, that comes later too.
