Hi all,

The project still ongoing, having received my adapter G36/M4 last Friday, I finally got to work on it.

So it's pretty simple, I cut all the dead volume of the room, once adapted to piston charger, you get this:

I also ordered last month a prototyping PCB for Arduino Uno to put all the electronics:

I'm still missing the charger that is being delivered, I will have to receive Wednesday to Thursday.
So soon find it for shooting video with a real supply of ammunition!

Nice
keep us updated

have you considered programming an attiny chip and putting the entire circuit on a perfoboard (for the final version naturally)?
that way you could make it more compact and still have arduino for other stuff

It is true that it is a good idea!
But I do not know programming set "Attiny".

or if attiny wouldn't be up to the job you might as well use an atmega chip

Thank you very much for the video.
If I do not have enough room to put my Arduino Uno in the carcass, I réviserai my choice ;).

Oooooh very nice! Power is not extraordinary but I love the selectable rates of fire and reliable feeding, bravo!

Thank you!

There will surely other test later

Very nice! Love the design.

Well considering it's only being used at 3 and 4 bar, there is scope for quite a bit of extra power as long as the flow through the 3/2valve is good enough to fill the chamber in time at higher pressures.


Can you adjust the rate of fire of the 3 round burst separately from the full auto?
When I was experimenting with my code I found that the 3 round burst seemed a lot cooler when it was faster than the basic full auto :)

Thank you!

The rate remains the same for all, if I'm 8cp/s semi-automatic, when I pass in automatic or burst 3cps, I'll always be 8cp/s.

I really appreciate the steady progress on this project. Coming along nicely. And kudos to you for keeping to your original concepts. If keeping my boss happy (and wife and children and pets and etc) didn't take all of my time... oh the possibilities.

Hi all,

For two days, I could make a silencer for my pac.
It consists of a stainless steel tube 304L 1 "1/4" (Ø42mm). For noise reduction, I opted for the towel 5/6tours "professional" with behind wool insulation for tanks that are carried out in boiler.

It reduces a lot of noise, I was impressed, vacuum, I heard that the exhaust air out of the distributor.

Once everything is soldered, the more I machined around the poor:
