Open Source Paintball Board (OSPB) - Stress test

Well, after making a successful board with new components I was able to do some stress testing to see if the new MOSFETS I chose would hold up to repeated use.. The first test was to hook up the parts NewRaceOwner sent me to a old cocker I had sitting around.

Now I remember why people don't shoot mech cockers anymore.. They are a PAIN to get setup if nothing has been done before.. On this one I had to set it up from scratch and wow what a pain!

Anyways, after hooking it up to my SCUBA tank I shot it for a few minutes without any electronic failures.. I did however run out of air before my auto stop of 2000 shots was met.. SCUBA must have been low since I have been testing with it for a week or so without filling!

Rough Stats
CPS - 7 shots per second
Runtime - 5min 53 seconds
Shot Count - 2471
Electronic failures - 0

Well, at this point I'm trying to decide if I need to order a professional circuit board so I can get the sizign down better, or do more testing before I commit to a board design..... Choices choices!

I will probably hold off and try and get the CPS down lower (Timing) and do another stress test but with the gun doing something like 15CPS..  Then once I have that done, I will go for a professionally fabbed board so that I can start sizing components.

Open Source Paintball Board

Well, I know its been some time since my last update and Im sorry for the long delay in updates..

While I was making my first prototypes I made some mistakes in parts ordering and ended up wasting a lot of time (8-10hrs) and that really bummed me out on the project since I was on a roll. So with life creeping up I had to take a break from it. On the flip side, ive slowly been working away, and made some progress.

Ive made 3 printed circuit boards (with MISTAKES!) as well as ordered the wrong transistors and that set me back alot.. What I have made is one good prototype board, with the button pad interfaced, both solenoids interfaced. Im currently working on getting the eyes interfaced, but I made a mistake on the board (eyes are on ALL THE TIME) and thats a waste of battery. I have to re-work the board to change the connections and make them switchable.

As well, I think I am going to change the board type from the Arduino Pro, to the Teensyduino. Why you ask? SIZE! The Teensy is only .7 wide, and 1.2 long, while the Pro is .7wide and 1.6 long. Inside a frame every inch counts and this will help with some wiggle room!

Not much progress has been made on the programming front, but being completely honest, the programming is the easy part for me!

I included a video as well if you want to see what progress I have made with the board.
