I'm just about ready to talk about my latest project - its pretty major. I got a wild hair up my butt awhile back to create a fully automated system which runs from a PC. I had another thread in a private forum about the interface for some time, but the hardware has finally caught up to the software.
Here is my setup before upgrading: http://www.homebrewtalk.com/f11/my-new-herms-setup-39422/
Most everything has been modified. The stand has been repainted; obviously the control panel has been replaced; and industrial touchscreen monitor was added; the mash tun and hlt have added insulation - including the bottoms; the heating element was upgraded to a 5500w 220v element; and a stir motor and float switch have been added to the HLT.
Here is a few shot of my new rig as it currently stands. I'm running it through a full cycle right now. There are several wiring tasks that still need to be cleaned up, such as the float switch cable which is just sort of hanging there. I will try to explain it all in followup posts...
Here is a close-up of the touchscreen and app. I'll post much more about it later.
The breakout box behind the touchscreen. The first two sets of plugs are individually controlled through the buttons on the right of the screen. The third plug is wired together and is controlled by the "Aux Pwr" button. The 220v plug on the right is controlled by the app to toggle the heating element. The red button turns the PC on. The antenna on the right is for the wifi. Those red wires on the right are the float switch wire that is just temporarily rigged...
