Prototype Laser housing

This forms part of a now abandoned project of mine.
I had planned to use this as part of a laser fence system, complete with adjustable mounting etc.

I had intended to run this from a variety of power sources, most notably a 12v battery.

I have since discovered cheaper and more effective options.
To make this component of the system you will need:

1 X Laser module from Jaycar Cat No: XC4490 AUD $5
1 X 5V regulator board AMS1117 5V (Aliexpress) AUD $0.25
4 X 1N4004 Diodes (Jaycar)

Assemble the diodes (optional) into a bridge rectifier arrangement for polarity protection.
Connect these between the input wires and the 5V regulator.

Connect the output of the 5V regulator to the GND and S pins of the laser
GND to Negative, S to positive.

Insert into case, and glue in.

WARNING: if like me, you plan to pot the laser for waterproofing, be careful, as you may screw up the collimator.

Hot glue is a bad idea, Two part epoxy is much better, but keep it clear of the r
