Have you seen the Phidgets USB-based IO boards? They have boards that support many different
type of sensors including simple discrete IO, motors, etc. RTDs you can use their Bridge input
module but ...

haha. I put a waterproof housing on mine. I made it a big red switch :)Case in point

Why not a 30A 240V DPST switch? It's what I did. It's not a big red button, but serves the same
purpose. I bought it at Home Depot....because people like big red buttons. :)

The resistor returns a small amount of current from one of the phases (Red or Black) to ground
through the 'system grounding conductor'....It is certainly not what a professional designer
would come u...

It's forcing the GFCI to trip by shorting the hot to ground. THIS IS A TERRIBLE DESIGN. Don't
do it! I'm resisting the urge to get on my soapbox about this virus of a design that has
infected this for...

You won't have a problem. If you're really concerned you could use a transformer to isolate
power to the PID or use a line reactor on your heater, but that is entirely unnecessary for a

I used a standard set of wire crimpers/cutters that had a crimper for insulated terminals. I
did not use the tool that is for sale on the electric brewery website.Is it advisable to use
some needle no...

There are PID algorithms written in C/C++ out there. There is probably already a version
written specifically for Arduino as well.

I wouldn't go to the trouble of changing what you already have. If they become a problem remove
them. They can be a point of failure, and really aren't necessary in most cases. They will
probably be o...

10AWG should be fine for 30A. hunter306 is probably correct--it's probably a poor connection.
Consider leaving the connector out. Maybe you aren't getting a good crimp. Connectors generally
