Wow, Thanks for the reply's ,
I'll try to answer as much as I can, I don't get on the net very often, as i'm in the sticks and can only use dial up.
"Obviously you plagiarised Bonj's design Jonathon " Not sure who that is but I will check out his rig.
edit: Checked it out! where were you when i needed insperation Bonj! awesome!!
This has totally been designed around a drawing of a brewery I saw on a black board, I took a photo and with the parts I could source I made somthing similar.
To start with, I would say the whole rig has cost me no more than $1500.
The Motorized valves are Honeywell VC6012 240v valve actuators. They were purchased for around $20 each surplus from www.oatleyelectronics.com they are good because they slowly (6 seconds ) actuate.
The USB controller is from HYTEK controls

around $100 for 16 digital IO and 8 analog inputs, software and drivers for Visual Basic ,Absolute gem.
Totally relies on a PC, so if your PC locks up, could make an interesting beer..
Every bit of work was done by myself, I tried to get mates to come around and help but they seem to laugh at me alot and drink, while i do all the geeky stuff.
Funny thing is, now its producing beer, they are alot more interested...
I am an industrial electrician with a decent workshop, Mills lathes and so forth and no missus.
"But it looks like you've spent too much time inventing and not enough brewing." Very true .. The cahllenge now is to brew some great beers..
The capper is as simple as it looks..
A SS frame, with a 50mm bore pneumatic cylinder with around 200mm stroke so it covers long necks and stubbies. The bell is out of one of those $3 hammer bottle cappers, its been drilled out so i can screw it to the cylinder shaft that i machined a 6mm thread into, a DCV (directional control valve) a push button (foot) and your done.. around 30 psi is plenty but 50psi is nice.
This is what my brother picked up for me yesterday at an auction, a 1150 litre jacketed mash tun (Milk vat)
For $220,, one day!!!
