Would anyone want a "dumb" electro?

If you want a couple local guys to test'em out for ya, I know a few lol

Is a capacitor alone really enough?

Don't you need some form of comparator and transistor?

Just a cap and a resistor will do the job. RC debounce. It swamps out the switch for r x c. Would have to do some math, but in theory this could be used to limit bps to tourney legal.

I'm not real big on electric guns. My ancient RT still hums. That said. I have an old trigger frame I'm not afraid to hack up. My wife's minimag that she wouldn't care if I played with. I'm drawing cad schematics now at work. And I play with wires. I'm interested to play with the idea. Use a big battery in the hopper and feed it in the trigger frame. It would just look like a old switch assisted hopper.

Have at it. I thought about a pressure switch as well but dropped the idea because paintballs are so light. I hadn't considered the effect of a force feed. Might run into trouble an the last few balls and/or when the marker is tilted.

My mental model of this has produced a number of funny results including full auto if the debounce isn't set up properly. Then again, that could be considered a feature. I can set it up with a trigger, debounce, eye's, and noid, no problem. There are mechanical variables that I won't be able to work out until I get it mounted on a marker.

Please keep us updated about your build. I'll start a thread for my own once I have something to show.

I've got a project and I'm right down the road... Let's say it's a sort of modified FASOR. Lemme know if it hits prototype stage.

There is no such thing as "drop in" for a mag platform that would be 100% reliable without various means to make adjustments and tuning. Ask Coolhand how he made out with those UEMF frames.

EM setups are right on the edge of what will trip the sear and what will fit in the frame. Devil mags and the UMEF are both good indicators of that.

Spider had a nice lil build like this..here is a thread he made awhile back:

This EP I did had a similar rationale (simplicity of operation). I still play with it. The only problems I've had are the quad o-rings getting old and the lack of a firing rate limit. Since it is uncapped and even I can hit 14bps with it, I can't say it is really limited to 13bps. It has no eyes either. You could set the firing rate to max out at 13bps, but without any code you have to throw away any trigger pulls outside of that speed. If I'm willing to shoot 10 or 11 bps, I'm probably willing to settle for 8 and go mechanical.

Wow, four years. I still think of that one as a newer mag. At least it got on the field faster than any of the EM designs, start to finish. I was actually wanting to make it EM originally, but I didn't like the margin of operation with the ULT and the tiny solenoids or the electronics with the larger solenoids.

I really do like the simple operation. I use a B2 (and level 10) and it feeds flawless, as fast as I can go. I leave it on all day, probably aired up too. It's like shooting a classic mag with a turbocharger that will kick in when you push it.

The lowest voltages I generally play with at work are 24 and 32 volts. I do a lot of customs control wiring with PLC. And high voltage cabling. I'm more than interested to play with your idea. But you would have to shoot me a pm with a basic electronics wire diagram and what rating and part for me to get the stuff together and solder it up. A basic diagram without any eyes or switches other than a trigger would be great. Other than that I'm useless. I haven't played with this small scale of electronics since college.

Idk how much logic them little chips hold. But couldn't it be done to where when you pull the trigger it will open the gate to pass current to the noir for x milliseconds for fire. Then times out and won't reset till the trigger is released? The time out could be set up and used as a cap for bps as well.

You may need a dead zone (read: hysteresis) to get things to debounce reliably.

That's just on the debounce end. There are going to be some issues on the solenoid end as well I think.

I'm sure you'll figure it out.

In a word: lots. These are the boards I typically work with:

And you can do some very sophisticated stuff with them. My idea here however is to create a hardware only solution that does not use an IC (i.e cheaterproof). As far as the diagram goes, I'm still learning myself. My original concept (as the electro-literate here probably already figured out) does not work. Setting up the eyes inline produces automatic full auto. Every new ball completes the circuit. I'm testing the concept using LED's as stand ins for the outputs and break beam eyes (from arcade redemption games) as stand ins for the switches.

I have three concepts that work in my mental model but I'll have to mock them up. I'm sure there will be some unexpected results that seem obvious in retrospect. What I've learned so far is that the results being produced by modern electro's are likely impossible to achieve without some combination of ramping/queuing. In testing one I found something that (IMO) is disturbing. That is for another thread.

Hmmmmm. I'm gonna talk to our small scale electronics guy at work about what I / we are talking about here minus the eyes. See what pops in his head. Doing the system itself would be easy. A whole working system popped in my head quick. But I'm thinking with larger scale items. If I'm gonna mess with this I want everything in the grip frame except maybe the batteries. I will pull our smale scale guy in to this and see what parts we can get together that are smaller than general din rail mount relays and timers.

Maybe tonight I will throw the basic system I'm thinking of in print. If I get that together I'd be more than willing to email you the cad file if you want. You might be able to look at my system and know what smaller scale parts are needed to pull this off.
