Valve Time Controller

[Panzerbot]

Hey Guys
I have maked a program for a Valve time Controller
How does it works:
Most of you who have a Pneumatic flipant use a On/off switch to open/close the Valve.
The Problem is that the Valve is as long open as you turn the switch on.

My Controller makes that the Valve is only for x sec. (when you want one you must me say the opening time you need)
open regardless of how long you turn the switch on.


You can count the opening time the valve needs with this formula: volume of the piston / GasFlow of the Valve <------these things you can look in their instructions
When you maked the Valve and Piston by yourself than say me the sizes of the piston and i count the volume (but then is the opening time not a accurate time)

When some of you want one i will make some Controllers.
They will cost ~10€
Specifications:
4 ampere
1-3S Lipo (when you want one for 3S you must say me)
It will weight not more than 4g(I think it will weight 1g)
And the sice will be under 1,5cm x 1,5cm

I hope you understand what i write, you know, i´m a German ;D

can you make them to run at 24v+?

I think this will be not a Problem.
But because it looked to me like nobody needs one i hadn't make sinkers, so when you want one controller it would take some time...
It takes at least 2weeks, because i must desing/make the sinkers and i must order the electronics.
