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!

Great
What would be a max operating temperature for this?
The original oven went up to 250°c. I think it can go up to 300°c easily now with insulation!
@@BlackBeardProjects you can use it to dry welding electrodes
What kind of welder do you use?
Transformer or inverter based?
There's a very small chance you may have voided the warranty. 😈😈😈
What warranty?
@Nathan Yusuf Is she still your gf?
Damn. I'm still cackling to myself about your comment minutes later. Loved it, thanks for the laugh.
Nah dude at the counter said it covers anything
I have to admit that is going to be an awesome upgrade to that oven and nice job on that also
Its cool watching the Dremel cutting disks shrink in fast forward
Ikr so satisfying
I thought it looks about how it feels. When using them i swear you can see dollar signs in the sparks and dust
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.
This is definitely on my list of things to build my toaster oven doesn't get hot enough or hold temp well.
Using the recently restored sensitive drill! Neat!!
I give you a thumbs up before the videos is over, youre just that cool.
Much appreciated!
With not much refinement, you get an excellent incubator. Thanks for the idea!
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.
Great project, enjoyed that one.
Thanks for sharing.
Как всегда, смотреть одно удовольствие!
I agree! Blackbeard is the coolest!
You did a WAYYYYY better job than I did! Major props!
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
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
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.
I never do this myself. Well done man
I love you... :)... I'm addicted to your channel.. I would love to learn how to make things out of nothing...me and husband are planning to live off the grid... and these skills will totally come in handy😊😊.. You're a true inspiration
Awesome job! I've been meaning to do this for a couple years!
Lovely....wanting to do this for a long time exactly like this
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.
You are really a GREAT Handworker 👏👏👏💪
Very Cool project. Many uses for this.
oh yes going to give this a go.
love that bench drill
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.
Nice job on the insulation and PID controller something Also considered doing. regarding the insulation for back and bottom think I would put on the outside for those two areas so food does not splatter on it.
Good!
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
drilling holes in the corners before grinding makes it easier to finish the cut. Ask me how I know.
Happy to oblige. How do you know?
@@pekkasaarinen2902 1/4 century of sheet metal work. Thanks for asking!
Could I also suggest drilling holes for rivets before doing the cut to keep the rigidity and avoid some metal bending ? 🤔
Great upgrade/reuse Gader!
Inspiring; looking around the house for things to undo. I got a sneaky suspicion anything I touch won't go back together though
That's pretty awesome. That will come in real handy in future projects.
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.
That is an awesome build. Do you have a wiring diagram for it ?
Very impressive stuff Sir !!!!!!!!!!
Great video and oven build, thank you!
Very cool idea i need to try to make a similar
Молодца!
нужная штука.
Nice job
NICE one! Well done!

Nice job , i am gona work on my 56 liter oven
Badass!!
Enjoyed your video and gave it a Thumbs Up
Well done 👍👍👍
Good job 👍
Why mess with the kaowool for just tempering temps? I guess it keeps the controls/wiring cooler, but I hate that stuff . . .
Nice, never thought of that. Just wondering if that insulation is still in place after you flipped it around.
Nice work man, should be a great addition to the shop :)
I'd like to watch more videos of making a sword... but this video was really cool, great job🔥👌🏽
Use it for powder coating too...👍🇬🇧
Better than the original.
Your so creative. 😁
Hello big like 396 thanks for this good presentation
Author you are best!
Nice work. I need one like that but I doubt I will built it.
If you do the template cutouts with dremel often enough, do yourself a favor and buy the diamond cutoff wheel, it will save you a ton of time, and probably money in the long run.
saudações do Brasil a todos. oficina nova??? muito bom. será um ``aparato´´ realmente útil. sucesso.
I plan on insulationg my toaster oven in like this. I have doubts though because it has ventilation grilles and surley they are there for a reason.
Know this is an older post but I'm curious what's the upper end of the hear spectrum this can withstand
Nice job, but I couldn't help notice how noisy your beautifully restored drill press is. Why?
he has problems with the motor
Thanks!! Noisy? It sounds good to me, maybe it's different from when I used it on the workbench because the table I have it on now is less stable? Maybe just audio pitch difference? Not sure! It does sounds the same in real life anyway :) Thanks again
VFD and motor problem are now solved. Made a community post about that earlier this week!
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
it's still food safe if i dont put insulation inside?
How hot can you take an oven like this?
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!
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.
@@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.
After modifications, can that toaster use with food? I mean the insulator inside oven safe for food?
My kit didn’t not have a on/off switch what kind should I get?
What about the door, is it possible to double-glaze it or something similar, or would that not be much of a improvement?
That is use magnetron for microwave source?
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???
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.
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.
What temperature would it get to and hold with out burning up
Been looking to build a baking oven for paints and I think you just saved my butt. I assume I could do the same with any size oven?
Avoid microwave oven - I think you could be disappointed. :P
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
Ah! PIDs, no one knows how they work, but just follow the circuit scheme and plug into anything and watch the magic!
Never reverse engineer'd one, but the temperature prob is sense, and the relay output is just that. It changes the on time depending on the temperature setting + whatever temperature it's sensing.
So if it was sensing the room temperature, let's say 24.6C, but the target temperature was 670C, it would keep it running if no fail-safe was present. Tho it probably has one or two.
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?

Ciao devo adattare una resistenza ma ho paura che tocca il polo al telaio del forno cosa posso mettere come guarnizione hai una idea ?
hi y did you connect a relay
Hi your video is very good,may i know the name of the white insulator like sponge . Tq
SUPER!
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?
Done it!
Belo video abraço 🇧🇷
Nice work. Always wondered how much does it take you to make this? And how long? Can you put that in your videos? Thanks for sharing with us!!!
Very nice! I assume it's also capable of holding temps between 30-40°C? Like for careful food/herb drying purposes?
Whoa! What's the little adjustable wrench you used?
Good man
O meu TOC não deixou me ver esse vídeo tranquilho kkkk dava pra arrumar mais
How much insulation did you buy and use?
I can’t understand why do you insert the fiberglass inside the oven?
Do you have schematic somewhere?
Nice, what made you to make this? How much,how long?
Thank you.
hi, how to wire the heating element to the PID? pl show in video format, thanks
Can you show us the proper way to sharpen a knife? Everyone suggests different ways, I'm confused.
Are the last installed insulator in the oven fiberglass? Does it safe to use like that?
Is it ok to insulate inside the oven cavity with ceramic wool?, Isn't that health hazard?...
Good work by the way! I enjoyed the video...
Was that Noctua thermal paste i see...
No user serviceable parts inside
Hey are you selling this or where can I buy or get the cad? Thank you!
