you can use Ts (a kind of fitting that well looks like the letter T) to make a something that performs the same function. The biggest problem is finding the fittings in the right size. You are unlikely to find them in exactly the right size for you but you can insert metal tubes inside them to reach...

Edit Checked the diagram on the net (http://www.aliexpress.com/item-img/SNS-mechanical-valve-pneumatic-air-valve-2-position-3-way-JM-07/2033259576.html#). The description on ebay was wrong or I understood it incorrectly - it's a normally closed valve: How you should arrange it: R = air source A = th...

Well apparently spudding is not dead everywhere [youtube]https://youtu.be/kALCUBH5JIQ[/youtube] I wonder if they built it as a pneumatic for reduced report. Note the hissing sound prior to the gun firing. Is it a pilot valve ? Apparently it uses a piston valve. Wish there were more pictures - it see...

Damn watching this makes me realize 3 things:
1. I am getting old
2. we haven't got a simple to use portable hybrid yet
3. mobile c. uses some tarded sounds in his vids

ohh nice find

Just stumbeld upon it.


Guess it's not so dead

Well it's definatelly not what it used to be. Almost 10 years ago it was a vibrant place - every week and day there was something interesting and ground breaking. I think we reached a point where we maxed out pneumatics and hybrids require a lot of work to get right and that's where it all stopped. ...

Happy workers' day, for ya all.

I know but if you experiment with Arduinos you'll learn a lot about electronics along the way. These days the learning curve is really gentle and it has never been so easy. There are excelent video tutorials all over the internet and they are literally so clear that you could say that they are 'for ...

Microcontrollers. Ever heard of them ? Not to sound like a dick but seriously it's 2015 and arduinos are dirt cheap. Get one, experiment with it. You can then use it to program attiny chips and build really tiny circuits.

Consider QEV + 3way valve + air cylinder combo >>> http://www.spudfiles.com/pneumatic-cann ... 20259.html

damn... you see a video, hear russian language and you know something interesting/amazing/terrifying is about to happen

USA Y U no russia ?

Boosters aside. Fridge compressors are way better than tire compressors in every respect. Now when it comes to high pressures... even 400 psi will freak you out at first and you'll surely run into problems with sourcing parts that can handle such pressures (most stuff is only rated to 10 maybe 20 ba...

Build yourself a fridge compressor. It's much much much better

There are videos of the drone though. Here's one ->> https://www.youtube.com/watch?v=fYnBmxjfld4 Found it mentioned on a couple of forums and in articles so it's got to be true ;-) Seems legit and reminds me of that guy who was supposedly designing a gun lunched version of it and looking for advice ...
