Wow that's a clever modification! And the idea of putting a duct would help create a more laminar flow for better cooling indeed. I was actually considering replacing the solenoid with a sturdier valve capable of accepting higher pressures. Paired with a stronger DC motor I believe I could achieve t...

Thank you for the rehost! The compressor is from a small 2 gallons air compressor system. I picked it up at the local scrap yard, the motor had a blown fuse that I just replaced. It's surprisingly powerful for its size; It takes about 30seconds to pressurize everything at 100psi. The fan is really g...

I thought my project would be interesting for you. https://www.youtube.com/watch?v=OmfDpCNS-oQ&t=8s I built it for a school project. It's intended to shoot tennis ball (at 100psi = 70meters), but anything that fits in the barrel is potentially a projectile. I tried with a coke can and it fits perfec...
