Thanks! I wanted to keep it under 5 minutes since it's not a complete project, just an intro / explanation video, but maybe that wasn't necessary ¯\_(ツ)_/¯

@@itstriggy4814 it was a perfect video and straight to the point.

@@itstriggy4814 Stay Fast!!!! Ive been looking everywhere for someone like this. Can't state how refreshing the rapid fire content was.

And yet we all know why his girlfriend made him make this

@@itstriggy4814 no it's awesome, means it's easy to repeat it as I need to. Only thing I'd add is having the model number of the transistor in the description was easy to find anyway but may be difficult for those a bit hard of hearing or without strong English knowledge.

Glad to hear it!

Nice catch! I've included it in the circuit diagram in the description.

@@itstriggy4814 I want to know what or which diode can be used. Can you give a suggestion ?

@@antoniohernandez8367 1N4007 should do the trick

​@@itstriggy4814 Thanks for the info !

Thanks Jakob! You do in fact want to connect the grounds. Ground defines the point where there is zero voltage, so connecting the grounds ensures that the 5V and 12V have the save reference point.

Thanks Jeff!

I put some links in the description!

@@itstriggy4814 thank you! Its wonderful to watch learn, and DOING is the best way to master material. Ty again

it would require more parts like a proportional pneumatic valve and a position sensor on the cylinder to have that kind of control.

Sorry for the late reply! they're called tamiya connectors

Dc 12v

hmm that's definitely more tricky. I'm not sure how that would be done, let me know if you find anything!

For position control? From what I've seen, it's notoriously challenging without buying a $300+ sensor. I'm not familiar with capacitive proximity sensors specifically, though my intuition is that they might have trouble measuring accurately over the whole range of the stroke (in my case 175mm). Let me know if you find any good solutions!

@@itstriggy4814 I was actually thinking about a sensor that would simply activate an air cylinder when you place a bottle in a set position. It would be a substitute for pressing a button or a pedal.

@@macwol Oh, that should be pretty easy! Just check for a signal from your sensor in the loop of your Arduino code, and if the signal is high (and the piston isn't already activated), activate the piston. www.seeedstudio.com/Grove-PIR-Motion-Sensor.html

@9YearsLater It might be easier to have him press a button if his hands allow, but if you're keen on the voice idea, check out my JARVIS video! It covers basically exactly that.

Yep, look up pressure regulator :)

Yes - I'd want it too.

@@itstriggy4814 I get a blank screen at that link.... I have purchased all the parts for this I just need the diagram... thanks.

Me too, can you perhaps post it a different way?

Very kind of you!

It looks like it comes with the pneumatic cylinder

Princess Auto has everything you need in this video, except the Arduino.

I would also really like to know if a pneumatic actuator length of stroke can be controlled please.

110 PSI should be fine

I'm not 100% sure but the arduino he's using is an arduino Mega, and as for your second question, you should be able to use a different kind of piston, however be sure to check it's compatibility with the rest of your components, especially the pneumatic fittings.

"pneumatic tubing and fittings" should get you there

You should be good with just one valve and some Y connect fittings from amazon

Hi Sorin, the resistors for the LEDs? LEDs run at around 20mA, so those resistors are just to limit current flow. Using ~500ohms should be fine for all of them. resistor = voltage / 0.02 amps

Notice how the video only uses a single Arduino digital pin. That means you can duplicate the set-up and just attach it to another digital pin! :) You will probably want to hook up both valves to the same battery, no need to get two. Just make sure they're attached in parallel!

the Arduino has like 14 digital output pins so you can control up to 14 valves with one controller. A relay could take the place of the MOSFET that was used in this demo.

@@itstriggy4814 Awesome. Thanks so much! I was able to get things working (and diagnose that I'd blown several MOSFETs due to insufficient resistance). I also built a simulation in TinkerCad, and added a photoresistor circuit to make it light (i.e., motion) activated for props www.tinkercad.com/embed/1rdzFZYw81P

@@itstriggy4814 Hey man this link is no good... still got the wiring diagram? Thanks for the video, super helpful!

i think you’d do that by reducing the air pressure. pneumatics are usually used for snappy responses like this

Nope :) ukposts.info/have/v-deo/mZ6IjYarlq2H0Gg.html

Hm yeah for some reason the "share post" link seems to be linking to my patron account, not my creator account... Have any ideas where else to host the image?

Absolutely, just connect the positive lead of each valve to the transistor terminal instead of just one. And of course negative to ground for both as well.

I noticed the model is visible at 1:27, a Tailonz 4V210-08, and found it here: www.amazon.com/Tailonz-Pneumatic-Solenoid-4V210-08-Pilot-Operated/dp/B07SJFV7S3/

I've put links in the description! :)

Yes

It depends entirely on what you want to do with the cylinder. The cylinder will move with as little as like 10 PSI, but won't be able to really move anything. The smaller the compressor, the more often you have to fill it up, or keep it running during operation. If you only need the cylinder to actuate once or twice between refills, you could get away with a very small tank.

The compressor I use here is one of the cheaper and smaller ones. I think it was $99. That'll be tough to beat.
