Final Video - And so my next projec starts...Its ALIVE!!!

Progress report

Breadboard will be used to test parts of my design. Microcontroller stepper board is off the shelf and completely assempled.

I have to create a board that will hold my voltage regulators and the TIP122 outputs for my solenoid valves.

I always test everything on the breadboard before I solder.
 
Only a little bit of progress today, wife made me exercise :runaway: The circuitry for controlling the 24VDC air solenoid valves.

Hodge podge of bits. Controller is 5vdc, motor is 12 vdc and valves are 24vdc

Cool design. Keep posting. Actually when your done you should put up an instructable. I have a design for a speed controller with on and off switching with a 2x16lcd built on an arduino. I was trying to get rpm to display from an optical encoder idea, but never finished that part. What are you using as a driver for the motor? I have mine designed around a fet, should have just used a driver from dx or pololu for mine as that would have been easier. Very interested in this project as my one project rifle is chambered in .338sinmag which requires making a false shoulder and then fire forming the casings and annealing them would like help out. That and there is some thing really cool about this type of machine.
 
from back in the day of learning microcontrollers I had a Picaxe 28 project board kicking around. It uses the Picaxe 28X2 and the L293D chip (quadruple high-current
half-H drivers).

its a neat little board but I am having a rough time wrapping my brain around how to structure the program since it has been a while since I have done something like this.

Good for the brain, better than watching the boob-tube. :)

I used to play with pic stuff back awhile ago now and switched to arduino, arduino has a lot more support and the stackable boards work better for me. I would consider myself to be just about beginner, even though I have been playing with micro's since the 90's, just that it is an on-off hobby for me. One of the things I like about arduino also is that you can get it down to an extremely small foot print.

One trick I use when writing programs for any thing is that I put a large amount of descriptions right in to the program, when I come back to a project then the program will have all the work I did, sitting inside to refresh my memory. Not just the beginning description I put notes in to the program so I can refresh why things need to be a certain way.

As far as structuring your program, have a look at some of the sites for picaxe. Most of the programming at this level is very similar for the modern micro controllers, if you want to get some of the arduino sketchs I have found around the web I can pm them to you.
 
Nice setup, its really starting to look cool, smc valves? With the picaxe are you trying control the speed of the stepper, then control the valves based on the switch input? The shaft for the stepper motor and wheel did you make these or repurpose?
