I want to build a PID controller but being slightly anal about things I will not slap it into an old ice-cream tub.
So, what would be your ideal PID setup?
I will laser cut the box and bend into a nice little unit.
Some thoughts to start with:
Face plate - cutout for the PID, illuminated on/off rocker switch, maybe a fuse (or a resettable fuse).
Rear - In and out kettle plug, out for a PT100 temperature sensor.
Sides - holes / slots for heat to escape / alternatively in the bottom with feet to raise box off the surface.
I think I might make standoffs for the heatsink of the SSR so as not to transfer heat to the box.
Everything comes at a premium so this setup could be pricey.
I will probable not go the Banggood route as it appears as if their "specials" only come with type J or Type K thermocouplers.
Would one want 2 temperature probes? This would make the PID more expensive but not by much.
The PT100 probes come in various lengths - would I be correct I assuming that a 5mm x 50mm would fit into most thermowells?
Would one want to add a CT to monitor current - then a VA meter will be required unless the CT just triggers the PID alarm. A matching PID / VA meter will really push up the price though.
Ideas?
Wish list?
Bad idea, Home brewers are poor people!

- I have access to laser cutting so drilling holes into plastic AND spacing properly (and square) would drive me insane.
