This is just awesome. Really impressed with the whole project and I can't wait to see the finished product.

However, I'm happy to say it's almost game ready! For those of you that could care less about electronics stop reading now.. It gets complicated from here on out.

Admittedly I'm a bit of a noob when it comes to circuits, the issue I was having was that the solenoid was freewheeling on trigger input. I determined that simply replacing the board's stock hall effect (touchless magnetic switch - 1816L) with a micro switch causes the programmable intergrated circuit (PIC16F168) to read a crap ton of signal noise, making it reset the solenoid intermittently (half-cycles, no dwell=bad mojo). Soo with much reading and a few headaches I've figured out how to "debounce" the trigger input to produce a clean, squarewave output that makes the PIC happy.

Here's a diagram illustrating signal noise and squarewave output.
http://i1297.photobucket.com/albums/...ps5f3b65d7.png

The light in my head turned on while looking at the 1816L (hall-effect) switch, it shows a sxhmitt trigger and a npn transistor..long story short the Schmitt turns on the transistor producing clean output signals.
http://i1297.photobucket.com/albums/...ps6b1b1e84.png

So I recreated the Schmitt trigger circuit using a 200K ohm resistor, a 220 nanofarad capacitor, and 2 lines of an inverting Schmitt trigger (SN74LS14). It requires 2 lines of the inverting Schmitt to produce the low output when trigger is pressed. The capacitor and resistor are selected at specific values because the capacitor charging time determines the frequency of the signal into the Schmitt, too low of a frequency and the debounce effect is diminished. I chose a capacitor charge time of .05 of a second meaning a trigger input any greater than 20 times per second would still result in only 20 cycles.

Simple circuit before the Schmitt..

Heres my test rig

So yeah, this will work on any TM series or invert mini with hall effect switch.. There are other ways using logic gates IC's or 555 timers, but I wont go into that.. This works lol.

Just need to get my velocity up a bit now, its hovering around 200 at the moment.
hi, what are the resistor and cap values?

I used a 200k ohm resister and 220nF capacitor (.22uF)

Calculation I used was:

Q(time)=CV(1-e^(-t/RC))

It yields .044s
1/.044= 22.7hz

Feel free to correct any of this, like I said I'm a noob when it comes to electronics.

noob?
who are you trying to fool?


I feel like we should keep groveling at your glory because good ****ing god, Dukie might have some competition in the small shop milsim guns market.

If this is easy to work on for the end user, I really can't see how you can't get less than... $800 per?

Dash that, I only have $420 in paypal.

I really can't see how you can't get less than $420 per :P

Long way to go before I can claim I know electronics. Thanks for the compliment, high praise I hope to be worthy of with time.
I'm considering a small production run (5 units) on an ION based conversion, TX2 if you will. I owe my buddy one, so it is already in the works.. No idea on pricing, but it'd be along the lines of kit pricing (build it yourself) vs marker pricing..

Still waiting on machine time unfortunately, I'll have an update soon.

Just wanted to say... Very cool.

Really dig the build - looking fw to seeing the next gen!

Well, if you do an Ion, consider making the bodies more small SMG-esque. The ion assembly can allow for that and since it's naturally going to be quiet (and hopefully B.O.B + hardlined.) and smooth, you can throw fake suppressors on there and the cosmetics will fit with the sound signature very well. (because we all know putting an apex2 or some fake suppressor on a tippmann or ATS looks corny when it still sounds like gun shots.

Def an Ion application is hot. Price dependent count me as very interested.
