Hahahah very cute how it loads itself step by step. :lol:

MrCrowley is right, I also (highly) recommend switching to a PC fan built inside the chamber, running it nonstop.
Also, propane metering would be an upgrade that will probably be even easier to build than your robotic spraynpray setup. However, it looks cool due to its complexness.

Maybe just build a second one with some upgrades?

I love the over engineered aspect of this.

Simply the best "spray and pray" on spudfiles. possibly the internet.

I love it. :twisted:

Velocity is about 96 m/s, I updated the page.
And I don't plan to build another one in the near future, it took a rather alot of time to build and tune.

Thanks for all the nice replies! :)
