SpudFiles

Hahahah very cute how it loads itself step by step.

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.

wonder if he will ever post on this forum again.. hopefully hes not another one of those awesome cannon builder one-time posters...

Velocity?

thats awesome looks complex, but you should have gone with a meter set up

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!

nice... 211 joules assuming you are using the The United States Golf Association regulation weight golf ball...
