Thank you for the info. It's been a while since I looked at them and I wasn't aware of CO2 laser cutters.
Can I ask what laser cutter you have and where you bought it from? I'm really interested in buying one but the last time I looked at them, I wasn't confident that they'd live up to expectations. The cuts in your project are very clean and something I'd love to have a go at.

This reminded me of a childhood friend's play house and the countless hours spent playing there. That was also an A-frame but the floor was installed part way up the A, making it a little more like a tree house with empty space beneath and a short ladder up to the door. Great build, thank you for sharing.
Wow, fantastic project, thank you for the time you took to document and share it. The Eye of Providence was a nice touch.
Prototype to PCB by Using Autodesk Circuits
The experimentation is probably my favourite part (besides making sounds). I found another diagram for this circuit that has a 9v DC barrel and shows a diode, seemingly between the 220uF cap and the first 10k resistor. I'm struggling to limit myself to one project at a time but once I've finished I'll share my make.

On the list of components there is a 22uf cap but in the diagram it is 220uf. I'm relatively new to electronics so I could be wrong but it looks like the polarity is reversed and besides that I can't work out why it's there at all?
