I needed a way to somewhat accurately control the etching solution for the titanium parts I anodize and a hotplate with a simple PID temperature controller seemed the best/cheapest way to do that. I already had the parts laying around so why not give it a try! - Věda a technologie
What do you guys think of the longer format? It may be a bit much but it's at least comprehensive, lol.
People might say that it's too long, but it's easy to tap the Right Arrow on the laptop or double tap the Right side of the phone screen to jump 5 10 seconds ahead.
It saves you they video editing time I guess?
I'd rather skip through parts of a longer video than not have that information available : ) It's valuable to see the continuous process, and I find the commentary/reasoning useful. Finally, I like seeing problems, errors, and on-the-spot troubleshooting included.
That said, there is a Goldilocks balance - shorter videos can be of equal value.
Keep up the good work!
Great job
Yep, the thermostat is just a bi-metallic strip. one metal expands more than the other so that it bends with temperature. The knob is just a screw to move the strip, and move when it trips.
"But I've got work to do and I'll fix it later"
- famous last words.
Yes, it takes the temperature of inside the body. It's a bimetal strip. It twists with heat. Pre-load can adjust how much heat you need it to click over, hence, it's a thermostat.
We already built and have a titanium anodizing process station we use with heat and distilled water agitator, so we will not watch this video however we love your channel and enjoy your use of support products we like and use as well. we really like your product the titanium key covers over on your website. Thank you Chris.
i am just doing this myself thanks for the guide those connectors are nice✌
@23:30 were you just casually grabbing that relay circuit board with exposed, live contacts at the bottom?
So what percentage of the Populus would you say see through your obfuscating ruse in the attempt to gain verbal elucidation anyway man? or is it just a cigar?
Temp control looks like a bi-metalic strip?
It does, which means it is just controlled by the temperature inside the box by the switch... I guess it works well enough to make raman noodles without burning your house down.
@@OwenAWilliams Apparently!
The large current flowing through the bimetallic strip generates its own heat, so tripping itself. Just like the old mechanical vehicle indicator flasher units (tic tic tic tic)
@@SimoWill75 intriguing... I took apart a toaster oven the other day and it had the same setup but they also had it connected to the wall of the oven with an aluminum angle bracket and thermal paste.
You can "properly" restore the fuses. Use a hot lighter (like a jet one) to heat a cap of the fuse to take off a cap. Save the sand. Take the other cap too; put a wire across, put one cap back, re-heat it on, pour sand back in, other cap on; and it's a restored fuse C:
Sounds like a lot of work for doing the same thing
You could have save yourself some time by measuring the resistance of the the element and calculated with I=E/R. Cheers
This is how I made my Sous vide cooker
Sorry the idea to built a PID controled stove is realy nice! I build one a few months ago for my self BUT
this video shows people how to DIE on a complicated way. To Wire fix fuses is one of the stupid things you can do because if it work again you don't care about it anymore... and there is a reason why there are fuses. Touching the unisolated relay while mains are connected.... a cable mess and more... there is no reason to hack into the internal of the el.heating.plate you can simply built a pox with a mains connector and plug the stove in.... sorry but this video shows how not to do such things....
