Hey Guys,
So the helmet is now finished and it was time to work on the range finder. Here is how I did it.
I bought a $8 2 Flasher LED kit from Jaycar Electronics, swapped out the 2nd green LED for a red one I had spare and started on building the circuit board.
I then took it for a test drive running from a 9V battery to make sure it was working.
Next stop Dremmel City population me as I had to chop off the sides of the board carefully so It could fit inside the housing of the RF.
2x LEDs are then zap a gapped into their respective holes.
I then made some room for the wires from the hollow stalk to move freely into the helmet where the power supply will live. i also drilled some small holes for the momentary switch that I picked up for $1.50. That is resting on a piece of plastic from a 3.5mm stereo jack plastic cover (not shown in pictures).
I then soldered and heat shrinked the leads from the LED's to the leads from the 9v Battery / Momentary switch.
I hollowed out the clear part of the RF topper where I am going to insert a white LED later on once I get one. It currently attaches with small magnets to the RF housing.
This is what it looks like from the inside. The battery is held by double sided velcro nicely and does not budge. Fits nicely when I am wearing the helmet.
A video of it working
Hope you all enjoyed this post
Cheers
