When the floor of my workshop was littered with metal chips , for the thousands time over, I decided to build a Arduino Digital Air Pressure Regulator.
Simple is often better. So I grab an old blowgun and used this a valve. The Arduino Digital Air Pressure Regulator uses a Nema 17 Steppermotor to press the leaver of the blowgun. A micro end switch was placed against the leaver. When the Arduino Nano goes through the setup the stepper hits the end switch, now the program knows the exact position of the stepper.
Because I never worked with Arduino before the programming of the Arduino Digital Air Pressure Regulator turned out to be quite difficult. After many hours studying I was able to write a program. The ArduinoForum.cc community helped me big time with debugging and improving the sketch. So thanks a lot for that!
After putting all the parts together it was time to test the Arduino Digital Air Pressure Regulator. I assumed there would be some thinks that had to be improved, but to my surprise It worked just like I had designed it. No bad for a first project right?

I hate to nit pick, but this is a FLOW/Volume regulator, not a PRESSURE regulator. Still cool build, I enjoyed watching, but the static/stopped pressure would be the same. thats why when you first pull the trigger you get a big rush, then it reduces. Anyways, thanks for the video, nice to see cool DIY projects like this. Thanks again
exactly!
Michael, Would you be able to regulate pressure with this Arduino unit in the following manner, I am new to this and would require the input pressure (100 psi / 7 bar max) to be regulated to output pressures of 5 different settings from 72.5 psi (5bar) to 0 psi
@@adrianking3633 I mean you are kind of on the right track already. You would need to design and 3d print a gearbox to adjust the regulator that you showed in the video. those use a diaphragm and a spring regulated bypass to actually adjust the pressure required to allow FLOW. it is really the only way to regulate pressure.
What I am trying to say if that you have the right parts, but you are controlling the wrong piece.
That's so cool! I wish I had friends that build stuff like this!
This is incredible thanks and keep making stuff.
Why not just use the Nano to PWM a solenoid? Put a pressure sensor at the output and use closed loop to regulate the PWM duty. Rube Goldberging it with a stepper is cool but unnecessarily complicated. :-)
Good point! A solenoid would have been much easier. The reason for this setup is that i had all this stuff laying around from a canceled project. So I asked myself: what kind of gadget can I build with this? And it turned out to be this Rube Goldberg style pressure regulator XD
Yeah, that's what I was looking for.. I got 140psi going to a AIRTAC GFR300 Regulator which is then going to a Baomain 4V410-15 Pneumatic Solenoid.. At the moment I am trying to control the AIRTEC Regulator flow to have control of the Pressure being sent through the open Solenoid.. The idea of just putting a servo on the Regulator is kinda crappy.. I figured there has to be some sort of regulator I can hook up between the two for var control.
Excellent
well worth its money
PARABÉNS !!!
Exelente!!
A very creative and interesting/inspiring Arduino application ! Well done !
Thanks Philip! I’m glad you like my video.
Should have just made the stepper motor control the regulator you already had.
exactly....
Stepper motor might not have enough torque to turn a regulator..
@@AndreDing11 If it didn't, it would be fairly simple to print a gear reduction of some sort. Probably a worm drive would be necessary to turn it, since regulator's tend to be pretty stiff at the top end of the scale.
What's the application name, the one you were using?
This is awesome. I want to get my 14 year old son interested in practical application of arduino and other microprocessors..its one thing to do simple tasks like lighting up LEDs
This may help me on a project as well.
I want to put air bags on my square baler to control bale tension. I'll need to have the ability to change the pressure setting, as well as have the air bags automatically adjust based on changes in the pressure exerted on the bags by the crop.
We measured weight of axles on our big air ride tricks by placing a gauge on the bags. 30 psi was roughly 6,000 lbs over 4 bags (2 axles) and 60 psi would indicate near 34,000 lbs.
I envision a digital display for presets of various pressures for the different crops to end up with consistent bale weights.
The baler was made in the 60's and it takes forever to get the bale size right, by then crop conditions change and the bales get too heavy or too light and the tension springs have to be adjusted.
Modern balers use hydraulic tension with gauges to monitor, so when the gauge pressure changes, the hydraulic input can be adjusted to maintain consistency across changing crop conditions.
I can't afford a modern baler, yet. But if I can make this old baler perform like a new one, I won't have to.
Except I will use solenoids and orifice valves and pwm to control the air pressure regulation.
Thanks Travis! That sounds like an awesome project you have planned.
Nice job I am looking at something similar to continually fill a gas bottle converted to air, I want it to turn on the compressor when the level of air decreases, might look at pwm in one of the comments.
well done ... turn the music off though and we can hear the air :-)
Nice looking lathe!
Also, how are you getting your close up shots? really well done.
Thanks Jeremy,
The footage of the lathe is made by positioning the camera tripod a couple of meters away. Put the focus on manual and search for the shot where the workpiece is in focus and the cross-slide/toolholder out of focus. that's all :)
I’m really impressed by your ClearWalker Strandbeest. The transparency of the polycarbonaat just gives it that extra magic effect.. Great job!
Thanks so much! Was a fun project.
Nice. I tend to record what I'm doing with a GoPro, then see what I get later - probably a good idea to give it more thought during the shooting process.
Great stuff, really well done. Any plans to stick the code up on Github?
Thanks! Code is coming up soon.
would be grateful the stl too

Cool, thanks.
Well done, But technically its an digital airflow regulator and not at pressure regulator. you should use de stepper motor to turn the knob of te pressure regulator you showed in the beginning of te video.
greets from a fellow Dutchman, and If i'm hearing correct even fellow Frysian!
Thanks Eddy, Yes on the Dutch no on the Frysian.

INTERESTING, LOL
Horrible soldering there, man! Your wires will easily come off and become disconnected with the way you soldered them!
That's some terrible soldering work.
Get rid of that awful music.
Worthless
