Thanks Bro. I have made one or two Halloween animatronics using motors before but these give slow motions so I want to make one with pneumatics so it can be quicker and more like a jumpscare. This video helped me out a ton.
I’m looking to make a prop electric chair and need something to make the dummy shake. how would I make the cylinder automatically open and close without having to press a button
Sure. This is fairly easy to do with a microcontroller like Arduino. Just search YT for the keywords Arduino and Pneumatics to find many. James Bruton is one of my favorites th-cam.com/video/d7ErG5ecO2s/w-d-xo.html but check some others as well that go more into the details? One thing: many of the examples I found are using Relays. Keep in mind that mechanical relays don't like being turned on/off very fast, so it's often better to use an SSR instead?
I always get confused because i always think if i want the rod end to come out slower i need to adjust the flow control on the closed end and if i want the rod end to go in slower i neer to adjust the flow control on the rod end i must be lookint at it as air coming in instead of air exhausting out

Stupid Question but at 12:50 the cylinder is permanently extended until you press the button. If you swap A & B, would the cylinder be permanently retracted until you press the button? I want to build a horror animatronic that jumps out from behind a gravestone, for example, so I need it the other way round.
Not so loud that it scares me? The most important is to have a pressure chamber so the compressor does not have to run all the time. Beyond that, you pretty much pay per decibel of reduced noise so it really depends on your budget. Any cheap compressor will be loud basically.
How did your ball launcher turn out? I wanted to make something similar that would be able to shoot a basketball ball up to 20-25 feet. Would everything just need to be sized up to handle that?
It actually ended up beeing opposite of what I thought. If you try to blow something inside a tube, it'll fail at some point. The ball will stop inside the tube. What I had to do was to use under-pressure. Turned out great and have been running all year for 4 years at the museeum by now. They're very happy with the installation.
Very nice demonstration. Question , the double acting actuator was in the extended position can it be started in the retracted position? What is the advantage of the double vers the single with the spring to retract?
Hi Steve. With a Double Acting cylinder, you can start at either position as long as you maintain pressure. If you release pressure, gravity takes over. The primary advantage is however to control the speed. If you want a Single Acting cylinder that starts in the expanded position, you can find this also but it's more common to find the opposite. Google words like "single acting spring extend air cylinder" and you'll find it.
@@JensChrBrynildsen Thank you. Will go for the double action. I need the action to start in the retracted position, (pressurized) nice to have the option to control speed.
Hey so I got some Tailonz pneumatic fittings, solenoid valves and such the 1/4 NPT. I have no idea how to connect that to a compressor. Part wise I can't seem to find anything. Is there any recommendations?
Heya. I have no idea where in the world you are, so it's hard to offer specific advice. But - if you go to a proper hardware store that sells pneumatic tools & fittings, they can give you advice. Bring a valve to explain? (And no - Harbour Freight is not the kind of hardware store I think about here. You'll need somewhere that knows more than selling cheap stuff)
I would need more info on expected cutting speed, the size of the setup and much more to advice on that, but just start with something that has a tank? If that runs out of air, you'll know that you need something bigger.
I love the idea! Please build one! I'd use a "boiler" a kettle of pressure like on a steam train. You'll have to constantly adjust pressure and have emergency valves in case pressure gets too high.
You could totally do, but it seems a little wasteful? Will be expensive in the long run :) This guy has a good explanation of his setup th-cam.com/video/wCxJ12s1-cI/w-d-xo.html and CO2 makes much more sense than air.
@@JensChrBrynildsen yup. I find that there is very little choice in Ireland and it's usually twice the price. Your video is brilliant tho.

Eddie Quinn That was quite expensive. What I have is a mix of parts that I used in a customer project and things I found on Banggood & Aliexpress.

Heya. Just check the description for links. So many asked me for this, so I added them. This isn't hydraulics though as that would require a fluid in the lines. Same, same, but different?
Hi! This is something you will need to calculate based on the size of the piston, the area and pressure. Try searching "Pneumatic Cylinder Force Calculator" to find a tool that can make this easier?
Hi Chris. I have not done that myself, but I would think that would work in general? I'd look at the specification of each item in your setup to see if it is doable as especially valves would need to support it. I had a look and the ones I have do all require positive pressure to work as intended. I'd look at the Festo homepage to read their data sheets.
Hi. Sorry for not responding sooner. What you can fit and how you can fit it does depend on your wheelchair. It really isn't my expertise in any way, but keep in mind that you'll need an air tank somewhere in addition to the pneumatics? The tank must likely be fitted low to increase stability since it has some weight. A bit too much unknown to be of any help in a YT comment I'm afraid.
Most small compressors will give you at least 8 bars of pressure and that's enough, unless you are moving something heavy. Look for a compressor that has a tank, so the motor does not have to start all the time?
Hi. Your parts (actuators, valves) will have connector that have a specific size. You select this when you buy and most parts come with connectors for different tube sizes. Its easier if you just use a single size in your setup, but you can also find connectors that go from 4 to 6 or 8mm tube (and others). Its very flexible in other words.
@@JensChrBrynildsen hi thanks for your reply, what I actually meant was, what determines that you would need to use, say 8mm instead of say 6mm in your design; a bit like when using electrical cabling, it would be the amps drawn by the load that would tell you to use a 2.5mm cable rather than 1.5mm.
@@tj9382 Ahh. I have not had a need for this, but larger diameters can hold more volume vs pressure. For large actuators, it would take a very long time to open/close with a 4mm tube, given that there is also a limit to how much pressure you can (and should) apply. An 8mm tube has 4 times the area and can thus actuate a large valve 4 times faster :)
I have found that some of these are not be able to hold the pressure at max for more than a few seconds. Another problem is that it will produce noise continuously. If the noise is no problem, you can give it a shot. I would recommend getting one that has a pressure chamber though - even if it's just a small one. Start with a small that you treat well and then sell it when you find that you need something bigger?
Hi can not using a air tank to lift weight weaken the strength the cylinder not lifting one side off my chassis im only using air pump 7.4v lipo battery and lego air cylinder
@@TW39 Ok.I still don't understand your question though? Do you wonder how to get more "pressure/lift"? The easy answer is to not use cylinders made for LEGO since there are obvious limits to how much pressure a plastic cylider can hold.
Hi. This depends on your specific device. The one's listed under the video are 12V (as written), but you'll find others as well. 24V is a common battery on trucks/lorries, so that's also common. There's also 110/230V solenoids available. Amperage is directly related to how strong the solenoid is. These small one's won't pull much, but look at their datasheet and you'll find what you need.
