Dive Compass - Part #3 - New board...

After the first prototype I added the two hall effects sensors as a way of controlling the current active way points and a second RGB LED for showing extra information...

So it started out as this... You really have to prototype on a breadboard, its so much easier...

Then moving to Vero board...

Break in copper strips made down the middle...

Completed board..

Both RGB LEDs are on the underside because I was running out of space topside..

You can see them a bit better from this view..

And here.... you can also one of the hall effect devices, they are place at the edge of the board to sense the magnetic field outside the housing. The second one is at the other end of the board to make them more easily distinguished.

Back in the tube, with battery and mounted on a mask. This prototype needs to go quite forward for the diver to be able to see the LEDs. Its quite fiddly trying to mount a cylinder on a flimsy bit of rubber mask strap...But will do for now...
