This is a list and explanation of all the parts for your PID. You can google search all of these or purchase some locally at your Lowes or Home Depot. I use the MYPIN TA4 SSR controller. You will need a box - the one in the video was ordered through MCM electronics. You will also need the following: A Fotek 25DA Solid State Relay (SSR) A heat sink for the SSR K-type Thermo couple (probe with 2 wires to sense temperature) 20 Amp 120Volt switch (Lowes or Home Depot) 20 Amp 120Volt receptacle (Lowes or Home Depot) Some 14AWG wire to wire the circuit Optional 16 AWG wire for signaling and power for the PID A means to cutout holes in your project box (dremmel tool is great) Some basic tools like screw driver, needle-nose pliers, wire stripper, some electrical connectors (forked type). A little patience and the review of these videos. Good luck and have fun.
