maserCycle.py – Cycle through lasers on servos and draw lines

1254 0

This is the third of five articles on my 2017 laser science project “Rock, Paper, Lasers.”

WEAR GOGGLES.

To use this code you should have read part one, for servo control, and part two for laser control.

DO NOT DELETE THE PART OF THE CODE THAT REMINDS YOU TO WEAR GOGGLES.

After the project was completed, I used this to make lines and squares. I want to go back and make stars and circles too.

DID I MENTION THE RIGHT COLOR GOGGLES ARE REALLY IMPORTANT?

I started playing with different ways to make the lasers visible too, I got a lot of advice from people, and some of it worked out well. In the end, only a real fog machine was able to do the work.

DON’T FORGET THE GOGGLES.

The little fog machines for science kits and projects didn’t make enough fog, my dad broke my “fog gun,” and other methods were less than successful, although some of them made my new makerspace smell really funny. Big fog machines are fun to play with. 

WATCH THE FUN VIDEOS.  IF YOU DO THIS IN PERSON WEAR GOGGLES. USE VIDEO TO VIEW IT IN FULL LATER.

This one is a view of the lasers firing with the fog machine running for a few seconds at the beginning and then again at the end of the video.

 

This one is a view from the pi-camera inside the fire box :
