So this project has been a mental exercise for a few years now, but I have finally decided to make it happen.
I have decided to make an electric mashing system for brewing but have been make decisions with the assumption that I will likely be graduating to a 220v system in the future.
For a chassis / structure I am using a wire shelving system from Home Depot (the stainless $100 variety) - these are the same shelves that every restaurant I have seen uses for storage in the freezer/refrigerator and their dry storage.
Most electrical components will be housed in a box I found on Amazon for cheap : http://www.amazon.com/gp/product/B005T94MQU/ref=oh_details_o06_s00_i00
AC will be provided to the heating elements, which according to math, should consume about 13 amps. Considering that most of the breakers in my house are 15 amp rated, I will need to watch usage closely.
Providing power to all over components will be a standard ATX computer power supply. Things such as the solenoids, pump (likely will be ordering a Chugger after I burn this little US Solar pump out) and any other power requirements will be provided by the ATX P/S and power control provided by a NPN transistor, though I have been tossing the idea of a darlington type array of NPN's to safely and with some stability provide power to all components. Thoughts?
