Do It Yourself 

Here is the first version  but with this list you just attach the cables of the items and close them with the heat-shrink and you're good to go (you no longer need to weld or add a switch as it is integrated into the battery holder).

It is very important for us top be transparent. So please know that all of the links beneath are associates links with us, which means that we make commission if you buy these items through these sellers. We are using this money to fuel the project and research. So if you’re interested supporting our efforts, you should feel pretty good about buying through these sellers. However, if you just want to run the experiment and would like to source the parts yourself, please do so. Just make sure that the laser is never above 5mW. This is so you protect your eyes while exploring. 

Thank you for your interest in our project. Let’s discover new worlds together. 

These are the parts that you can order and assemble together to get the laser with the right characteristics.

1. Laser with Diffractor

2. Battery Holder with on/off switch

3. Tripod (feel free to mount it any other way)

4. Heat Shrink

5. Electric Tape

6. Wire Stripper
