I really enjoyed how to showed your thinking process follow each failure.
Frankly, closed loop toasters did kind of exist back in the 60s! Technology Connections had a video on that
Just checked it out! Very cool, we need to go back to that system
oh man i had a bunch of nitinol growing up in the 90's, including these piston/actuator things that were super fun to play with
You can use the non stretching wire as well by winding it into springs yourself and setting it's shape. Makes it easier to create designs with long travel.
I love this style of content! Take my sub and keep up the great work!
@Someone_Should_Make_That Interesting test! Take my like and keep up the great work!
Nice! Im also looking into nitinol for control surface actuators on a miniature glider for returning a sensor package a weather balloon. I was wondering just how controllable nitinol is, and found your channel.
I've never worked with NiTiNOL, so, sorry if it makes no sense. But...
Could you try driving it with a PWM fed MOSFET? Maybe the thermal inertia of the wire is enough to for you to have a stable control within reasonable frequencies.
Any linear power control will have big losses and need big dissipation.
Sounds like it could be worth the attempt! It’s already running with a pwm controlled mosfet so a test run to see if it overheats may be worthwhile, currently the current is limited by the extra resistance
@@Someone_Should_Make_That if that fails, you should consider a DC-DC converter. Won't be hard to integrate it to your PID. Keep us posted!
Kudos for the project!
The ADC isn't that noisy and really all of the MCU's are about the same. The problem is the circuit. Or more specifically a breadboard is terrible for anything sensitive to noise. You also need to make sure the AVCC power supply has proper decoupling and you can decouple the ADC input as well. It's pretty much mandatory to average a bunch of samples together to get one "sample" if you're not already doing that. MCU's have low impedance ADC inputs so make sure the ADC is getting enough current or boost with an op-amp.
it would be nice to see the schematic and put the link of the paper.
sweet old tektronix scope!
Thank you! I find there’s something so much cooler about the old analog scopes! Even if on paper they are much less capable haha
Batter cells are 1.8volts with a bigger resistor then balance the resistor load and ohms so u can set your volt amp. No need for the constant.
This comment gave me a stroke
You could just use 4 normal 1/4W resisters in series/parallel instead of your massive babies first one.
Not necessarily 'better' but you dont have to special order the big one at least.

👍👍👍
really looking forward to additional content about nitinol
Glad you enjoyed! I have some rough ideas in mind so hopefully they will turn into videos!
Wait you have friends? Real ones?
I wish I had friends who didn't message me back.
Everybody knows what Nitinol is?!
If by everyone you mean us nerds... yeah
