Hello gun.jpg Just finished my ak6 semi-auto and then i stumbled on some decent 12v valves:p So i have dissemble my gun to fit the new valves for more power! valve.jpg The valves can handle 75b@ 1100psi. I will use 50bar because my fridge compressor cant handle more and a soda stream tank. my old th...

You should put in a mpu and a solenoid :p but the dubble feed is a classic issue, i made a ball dent. A 4.5 mm stell ball and a spring :p it works great. But i have a spring loaded magazine.

I see, not easy to explain some Times, The first you describe is how my gun works now :) Have tried your config but a solenoid istead of the pop-off valve. Maybe a the pilot volume was to big and the solenoid to weak to seal again, need to experiment again, BTW i have contacted a valve company and t...

I just connected a regulator solenoid on the exhaust and a spring on the QEV piston. And the sodastream attached to port A . I can make a diagram later today

thanks its awsome to just plug in the gun to the pc and tweak the valves:P

Hehe have not tried them! think i will stick to the atmel chips:P

Thank you, yes they are nice to have, they do the things you tell them and nothing more:P haha Thinking to ad a third switch so the gun stops when the mag are empty! no dry fire. Yes thats the steel ball att 20 bars, going to test 25 later on. The valve are rated to 20 bars, if i remember correctly ...

I see. Sounds good. Think you will get some power out of solenoid at your PSI ratings:P Have tried my 3way solenoid up to 50bars and 10mm steel balls! It was rely hard to get it to open:( i can just say holy fuc# ! Got 100 jouls of energy! The recoil was insane! Dumped a hole soda stream true the qe...

Locking good:) are you going for single shoot? In my AK6 i need to go over 20volts to make it trigger at 20bar and 25bar i use 30v. My is rated for 12v and 20bars:P So boost the voltage and it should go faster! Ad a capacitor. btw do you have a link on the solenoid valve?

And a video, Just a crappy one, the microphone got overwhelmed by the gun:P

Hello guys, Have made a 6mm semi-auto bb gun:) It uses a QEV and a 3way NO solenoid for firing and a second solenoid for reloading. Everything is driven by a arduino nano and two transistors for firing control. Have also a fire select switch so i can have : safety, single, burst and full auto :P The...

Sweet! Just ordered both the QEV and the solenoid valve :) Hope they arrive soon! Just need to find a 24vdc power supply... You could use a dc step up converter from 12v etc. https://m.ebay.com/itm/DC-DC-Adjustable-Voltage-Booster-Power-Supply-Step-Up-1-5V-35V-XL6009-/141797927809?nav=SEARCH I use ...

Thank you, yea just a bit of prof of concept right now, going to ad rifle stock later.

Hello Building a gun that shoots 9.5mm steel balls :P Gun spec: 40BAR @ 171m/s = 73j. Trying to hit 100+ Joules. Ammo: 9.5mm 5g 10mm@49cm barrel QEV: qe-03 CO2 tank 605ml 12v solenoid Arduino controlling the pilot. Removable bolt. To do: Longer barrel, 75cm Buy 10mm steel balls. Round the bolt for b...

It depends on the pilot valve! IF you switch place with the soda and the trigger you will have a single shoot gun! You need to put a spring behind the gev piston to be able to fill the gun. If you need multishoot you will ned a hammer valve to pilot or a solenoid! Or just putt a 3 way valve to pilot...
