After lots of success with my first home made immersion circulator, I found myself in need of a rebuild. I had repeated trouble using the internal relays on both the JLD612 and CD100 PID controllers. They would last between 50-200 hours, and then no longer switch the current.
Mark II was to be bigger and better, so here are the changes I made:
- Solid State relay (controlled by JLD612) switching the AC circuit.
- More compact immersion element with fixed temperature probe mounting.
- 1500w heating element from a home water heater.
- More rugged case design.
Basically, the new version is faster and stronger…maybe just a little bit bigger.
My Mark II supply list:
*Ony 1 probe is needed for Sous Vide, but I recommend buying two of these so you can use one for your smoker.
(1) Water Pump
(1) GFCI Outlet
(1) 1" Plumbing nut
(1) Nut fitting PT100 probe (they come in different sizes)
(2-3) Washers fitting probe
(1) 5-10A switch
(2) stereo male 1/4’" plug (TRSS)
(1) stereo female 1/4" plug (TRSS)
(~15) Blue Spade connectors
Angle Grinder or rotozip fitted with cutting wheel
Drill + Bits.
Layout the components in the box, making sure they’ll fit on the inside. (I used post-it notes for this)
Cut the holes.
Drill holes in the bottom of the Ikea silverware container and mount the heating element and temp probe.
There’s been a lot of duscussion around settings on the JLD612, here are mine:
