Nice build! +1 rep

Why thanks cube!
By the way, when exactly do reps start building up? I have 3 green blocks, but not any levels. Do you need to obtain a certain post count? I read the info on reps but am a little confused on this.

I've made a few modifications such as adding a fan to the heatsink and a few general improvements, will post pictures and more soon :)

I'm keen to see them! I was actually just going to suggest some ventilation in your makeshift project box! Great work!

I attached a fan to the heatsink of the laser housing, it was actually getting rather warm after a few hours' use. It is attached straight to the 12V power input jack, and is always on irrelevant if the laser power switch is on or off.
The fan now keeps it very cool, so cool that the heatsink is much cooler than the ambient temperature :cool:
Here are the images:

I did not add a fan to the regulators inside the project box, as after running the project for 24 hours they were a little warm, but not nearly hot.
Their heatsink was still cold other than the areas directly next to the regulators.

This was a great little addition to the project :)
