i got some 3pack co2 cannisters for my beetleweight robot Ronnie O'Speedable (the robot is based on a snooker play who got 147 break 5mins 20secs) 2 other beetleweight are also based on famous snooker players. Ronnie O'Speedable will have a flipper, so wanted to if there hints 'n' tips, even diagrams on pneumatics for beetleweights.
I'm up for a challenge incuding build beetleweight pneumatic systems.
The diagram would be the same as for a raptor or featherweight, but with smaller parts. Here you have a Full Pressure setup with comments.
Here is a full pressure beetleweight built a while ago:

I think you have to go full pressure as there isn't much weight for a regulator but it could be possible.
The main challenge is finding a small enough solenoid valve, I would look into finding a very small hydraulic ball valve then open it with a servo.
Mario, you have turned down the 12oz Co2 bottle (the buffer) by 1/16"? I was thinking of doing the same but hesitated...now that I'm seeing it used as a FP buffer I'm less concerned... The tank's wall thickness is 3.4mm min so taking 2mm away the tank should still be able to hold 12bar no?Quote:

But for low pressure, 1.5mm should be enough.
On the other hand, with such a thin wall, any hickup or shatter when turning will give you less safety marge.
Do the hydrostatic pressure test please.
Thanks for the advice, I'll make sure the bottle is properly supported during turning and it should be fine...as for hydrotesting, it can be done but I doubt they'll issue a certificate for it
