Amazon Temp control deal

I couldn't help myself and bought a few. Don't have any need for them as already made 3 but at the price couldn't resist.
Will probably swap one of the short probes for the long one in my toaster oven and maybe put a couple together for shooting buddies.
 
Just starting to do some research on building my own pidd. Any type of electrician I certainly am not. I’ve started to watch the linked video but am only part way through it. I see somewhere else someone has used a plastic ammo box which is likely what I would use.

Couple questions. Would the same pidd work for my toaster oven that is used for my PC bullets? And would that make things any better? Where would I find a link to schematics (it’s possible I missed it on here).

Any other suggestions for a newbie? Thank you for your time.
 
Still researching but getting closer to ordering.

To answer my own question( I think). Yes I can use the pid for both my Lee 4-20 pot and powder coating toaster oven but it wil have to be reprogrammed. I have no idea how hard this will be or if it’s feasible as I have never built or used a pid to this point.

I will need to replace the thermocouple with a longer one. The one that comes with is rated for 400 C and some advise this is suffix. But should replace it with one that is rated to 1200 C?

Is anyone using Thermocouple Miniature Socket and Plug set on their pid or just hard wiring?

Are the wiring schematics the same for all pids or specific to each make. Will the ones I have found on various sites work.

Sorry for all the questions buy I’m hoping to do this correctly and order the right stuff the first go around.

I am just back from a bit of a vacation and am looking at ordering some parts for this build - and I wondered about the 400 degree C issue as well.

Thanks you once again Yomomma for all the help, tips and vids. Thanks to Helka for the PM (I will take you up on offer). You guys have been great. I will order the parts today. It will be a while before I’m mobile enough to complete things as I broke my ankle (did a good job if is do say so) last week. I won’t be too mobile for a while.

As luck would have it I had save a bunch of computer parts for a few years but decided to recycle them last winter when I was on a purge. I guess same can be said about crutches I donated ��.

Anyway thanks again all for all the help. ����
 
Wanted to give a shout out to Yomama for his help and guidance in both powder coating and building a PID controller for bullet casting. Not only did he mail me some 45-70 PC bullets to try for no charge he helped trouble shoot my PID build. Only said to pay it forward. I’ve done so by helping out a few older locals in similar situations (not that I’m a spring chicken).

So thanks to Yomama.

Question: Probe is short but would it work to drill a hole in the base of the pot and screw in the probe ?

The probe just has to be held against the side of the internal pot.
The older melting pots had a by-metal coil to control temperature that was a couple of cm away from the pot.
The P.I.D. units are overkill. I use the Rex C100 P.I.D. controller in on/off mode It keeps the pot + or - 2C I have a long probe that goes in the lead. but the short probe fastened to the Inner lining of the pot at the bottom works just as well.

In the past a Rex C100, SSR, and a K thermocouple cost about $18 CDN shipped direct from China.
I have built a couple dozen of these, put them salvaged computer power supply cases, they work really well
I used one on my powder coating toaster oven - works really well.

I even used a deep fryer with a Rex C100 to make a Sous vide to slow cook steaks and roasts.
 
Here it is!

I actually just posted this because I think I finally figured out how to post pics! I was reading the why no posting pictures rant and figured I would try once again. By the way nothing to do with being lazy. Anyway here’s my pid with a picture and all. I’m pretty tecky now.
