I love your videos and was wondering what type of diffuser did you use on top of the laser receivers? Are they a ping pong balls cut in half? Thanks

A vape coil/tank and small fan on a timer will give you a steady stream of low volume smoke, the vape coil/tank can be controlled via a MOSFET.

Could you not use an atomizer (water based), build it right in the box.

Yes, that would be a great way of having a completely safe way of visualising the laser beam! The only thing to worry about would be having some method of channelling the water droplets away from the electronics as it inevitably condensed on the inside surfaces of the box.

This is awesome. I need to gain some skills so I can build my own. I have never used arduino tech before...

And lovely to read your comment back! What strange times we are living in. I lived on Islay for 6 months and I regularly visit Edinburgh (not that I'll be doing so again for a while), and I could think of far worse places to be quarantined.... stay safe.

LOVE THIS PUZZLE!! Could you put a switch at bottom instead of the key? So the player has to turn on the switch without breaking the beams or the switch won't work.

Nice to see you again! As Matthew Hooks says, we are in quarantine up here in Barcelona (Catalonia). This is just the first week, but I think it's gonna be a long time isolated. Fortunately, I have a lot of arduino stuff and, thanks to your amazing videos, life is easier. I'll become an arduino master, hahaha... Thank you so much.

Thanks for your comment, and glad you're ok. It's been a crazy week, but I'm really trying to stay positive. I think keeping busy is really important, and learning new stuff is a great way of doing that (personally, I'm hoping to spend a bit of time practicing my woodworking skills!)

I remember 3 months ago you talked us about the ultrasonic mist creator. Do you think that can be useful here?
@PlayfulTechnology

Yes, absolutely - you could use a ultrasonic mister or any other method of creating fine water mist and that would be a totally safe medium to make the laser visible as it passed through - you just need some sort of particles in the air for it to reflect off. The only thing to be aware of is that water vapour will inevitably condense and make surfaces damp - you'd need to make sure these didn't interfere with the electronics.

"Lasers are inherently dangerous" No they absolutely aren't. That's some A-grade misinformation right there. There are MANY kinds of lasers, even visible enough for an escape room puzzle, which are less dangerous than safety scissors.

My dictionary defines dangerous as "able or likely to cause harm or injury". So both lasers and scissors are inherently dangerous. And, as I clearly stated in the video, the guidelines regarding laser usage differ from country to country. The UK guidelines are here: www.gov.uk/government/publications/laser-radiation-safety-advice/laser-radiation-safety-advice which state that even for a Class 2 laser (i.e.
