PID Controlled And Insulated Toaster Oven | DIY

Made another PID controlled oven to use in my upcoming projects.
Here in the new workshop I don't have access to a kitchen oven so I really needed something big enough to temper some of my longer blades. This will come in handy also to dry out stuff like wood for stabilization and to cook and cure well plaster molds for metal casting projects!
A real handy tool to have overall I think.
It's also pretty easy to build, even without metalworking tool, the eletronics can be left outside in any kind of box and it would make this project way easier! Of course be carefull with mais voltage if you try this, eletricity is sneaky!
And before you ask, the main reason why I don't use my high temperature oven to also temper blades is that I have to wait for it to cool down to tempering temperatures and that can take a really long time from, let's say, 1080°c.
So, the core of this oven is, well... A toaster oven! I found this one at my local thrift store for only 10€ because it was missing all the knobs. But it was otherwise new. So absolutely perfect for me!
Other components are the insulating ceramic wool and the PID controller kit that comes with K-type thermocouple, ssd relay and nice aluminum heat sink. Here are a couple links of similar item (yes, affiliate links, buy wherever you like)
amzn.to/2Y3Nce6
amzn.to/2XTpg1Q
Off camera I had to istall a 12v power supply for the PID as the one I got was not rated to work with 220v (unlike the other one I have on my high temp oven) and I also ended up doubling the insulating wool near the controller as it was still getting pretty hot near the heating elements.
List of producst and operations:
0:40 Remove unnecessary components, left only heating elements and fan
1:26 Cut opening for new control panel with angle grinder and cut off disk using masking tape as straight line reference
2:07 Cut metal sheet stock for the new control panel with metal cutting band saw (funny enough this metal comes from another oven, a microwave oven I took apart a while back)
2:30 Adapt a home switch for the control panel. I have some laying around with no better use.
2:43 Mark position for holes
3:00 Cut those holes with dremel tool
4:30 Drill holes for rivets to hold the new panel in place
5:27 3.5mm rivets, so easy to pop!
6:00 Black spray paint... Why not.
6:40 Install thermocouple
7:05 Ssd replay installed with thermal paste between back and heat sink
7:40 Stuff connected following PID instruction manual. Very easy for real, just 6 wires or so
8:17 Ceramic wool
8:40 Tried to use some in every side of the toaster chamber, except the front glass door of course
That's all! Make one if you need one, it's easy!
Thanks a lot for watching, I hope you liked the video!

Great project, enjoyed that one. Thanks for sharing.

[@imajeenyus42]

Great job! Been meaning to do that for a while on my cheap oven, currently got the controller attached with lots of loose wires 😁 I found that running the fan constantly and just using the controller to switch the heater resulted in better temperature control, since the air can settle out if the fan is switched off.

[@MemoGGG16]

Using the recently restored sensitive drill! Neat!!

[@BlazeOGlory]

That's pretty awesome. That will come in real handy in future projects.

[@theoneandonlyowl3764]

Black Beard, you're making me miss my trade, and working too, after watching videos like this of yours. Process control work in a factory or rewiring/upgrading complicated machinery with new nice components can be so much fun... or was for me. Very nice upgrade on the oven. Thanks.

Great

[@savageoutdoors474]

What would be a max operating temperature for this?

[@BlackBeardProjects]

The original oven went up to 250°c. I think it can go up to 300°c easily now with insulation!

[@walte99]

Great job man! I wish I knew how to alter the internal wiring of the oven like you. I just wired a female plug to the PID and then plug the oven in when ready to use. It creates a small problem or two, but nothing I cannot work around.

Very Cool project. Many uses for this.

[@RedBeardOps]

You did a WAYYYYY better job than I did! Major props!

[@RedBeardOps]

Hey man, Watching this got me to work on my toaster... I think I have my PID system tuned up better than it was before! Thanks for the inspiration and wherewithal

[@RedBeardOps]

So I moved my PID system from a dedicated "plug and play" box to integrated into my toaster side compartment. I must say it didn't workout. First tempering cycle my SSR blew up / melted down due to the heat. I had it insulated but... it probably could have been better. I'd suggest to most people that building a stand along PID box, then plugging your toaster into that box may be an easier and safer option (less heat to the SSR). To be fair my toaster is older... and my insulating job likely wasn't as good as yours. Just and idea for people looking to do this. Cheers

[@dcocz3908]

Inspiring; looking around the house for things to undo. I got a sneaky suspicion anything I touch won't go back together though

Depending on what you're using it for a couple bricks for thermal mass could help you maintain and even more constant temperature. Longer to heat up however.

[@jerryjohnsonii4181]

Very impressive stuff Sir !!!!!!!!!!

[@jgabler4433]

Awesome!! I found an old kitchenaid toaster oven in someones trash that looks brand new but wont heat up. I'm going to try this and see if I can get it going! If not I'll toss it and go thrift store shopping lol

[@bradyrose]

You could add some thermal mass with a baking stone, this should also help the PID stabilize the temperature, like a physical capacitor of sorts.

[@TheRedhawke]

That is an awesome build. Do you have a wiring diagram for it ?

[@rjperkins365]

Nice, never thought of that. Just wondering if that insulation is still in place after you flipped it around.

I made a similar oven for annealing polymax pc 3d printed parts. Even though their glass transition temp is 113 degrees, and I set my oven to 100c, it still melts the parts.

[@johnfrank3372]

Following your instructions, I got my own toaster oven/PID working with exception to the issue where the temperature fluctuates inside a 30C window. were you able to program the pid to keep a tighter control over the temperature?

[@uski]

Very very late response. But it may help someone in a similar boat. This type of issue can be caused by uneven temperature distribution within the oven (for instance if you use a solid sheet metal tray), a delay in the temperature sensor (only use a bare sensor not one encased into a metal rod), delay in the heat release from the heating element, or a badly tuned PID controlled loop. Or any combination thereof. So: 1) Get a convection oven, and hardwire the fan to run at all times 2) Make some holes in the tray, if you use the solid one, to ensure air and heat can circulate 3) Only use a bare temperature sensor, no metal tube 4) Follow internet tutorials to tune your PID loop, and be especially careful about the I parameter as it can create a lot of fluctuations if set too high. Hope this helps someone. I got the temperature right within a ~3 degrees band with a Walmart oven (non convection), but please get a convection one, it will make your life much easier

[@aperahamlincoln6168]

I’m trying to do this with a electric smoker. Is this the same way? Just bypass everything and hook to the heating element? Thanks

[@15nanoseconds]

Great vid!! So I've got this tiny toaster oven bought for clay jewelry projects. The problem is that it has only 1 temp. 450°. I need a range between 225° and 275°. Is it possible to modify?

[@quoctho2105]

Whoa! What's the little adjustable wrench you used?

[@JamesUKE92]

How hot can you take an oven like this?

[@kittikajorns1811]

Are the last installed insulator in the oven fiberglass? Does it safe to use like that?

[@idefyu23]

Was that Noctua thermal paste i see...

[@tomaszski9818]

Great project, Can I build something like that for PCB drying? I have problem when reballing some IC chips with "popcorn" effects. The best way I think is build oven like yours and get moisture out from electronics board and chips by sticking them inside the chamber for few hours. What do you think?

[@matthewdancik5515]

Since this oven is now PID controlled will that allow the oven to heat to higher temp than what it would typically? I don't really know much about this sort of thing, but I imagine there is a certain threshold for how hot the elements in said appliance can reach, and if so, what would that max temp be???

[@joesam8113]

Hi your video is very good,may i know the name of the white insulator like sponge . Tq

[@kuljeetsinghbedi6920]

hi, how to wire the heating element to the PID? pl show in video format, thanks

[@phatcap976]

where did you installed the temp sensor?

[@Hank254]

Very nice build. Can I ask... what PID values did you use? I did the same thing using an Arduino but I am having a hell of a time getting the tuning right, it always overshoots by ~20° before settling down to the set point. I think it is due to the extended time between when the heating elements are turned on/off until that change is registered by the thermocouple. Not sure if there is a way around that without the oven taking 20 minutes to hit the SP. Anyway, thanks for the video!

[@damionlowther78]

Check out barley and hops brewing they have videos on everything you would ever want to know about PID controllers. They cover over shoots in a video about setting parameters. Sorry cant remember exactly which one.

[@Hank254]

@@damionlowther78 Thanks... I ran across them in my searching; brought back memories of when I used to brew :) I think the problem was with the responsiveness of my system rather than the tuning itself. I ended up modifying the algorithm slightly and it works fine now.

What about the door, is it possible to double-glaze it or something similar, or would that not be much of a improvement?

Could you share your PID settings? I've built something similar, also with an InkBird PID. But it's not hitting the set point very well. It overshoots by 25F and then drops below by 25F.

[@matthewdancik5515]

Not sure if you did this, but supposedly there's a self calibrating function that should be performed which will help in a more accurate temp setting...

How much would you charge to make one of these 50 liters and send it to Brazil? The voltage here is 110 or 220 volts

[@darengnjatovic9358]

I'm probably missing something but why did you use a PID controller? It's used to adjust output power to make the heating up process shorter but these small ovens usually use only full power or nothing. If it was just about holding the temperature, you could have hard patched the temperature sensor to the main switch (you would need a voltage controlled switch, but they cost nothing) and it would hold the temperature.

[@USA__2023]

I used to feel the same way about a lot of PID projects that I've seen. In most of them the PID is not needed. But they are very cheap and programmable. So cheap that I've used them for AUX temp displays.
