Control compressed air nozzle with RASPI

Hi. I'm trying to have code on a raspberry pi shoot compressed air at items, but am not really sure where to start regarding the hardware for the nozzles and actuators.

Is there anywhere I can go to get buying options (or more info) on this.

 

Looking for something that operates quickly and reliably.

 

Thx in advance for any help ?

I would use an Arduino instead of a Pi for something like this. From what you're describing it would be cheaper and better suited for your task.

Quote me to see my reply!

The thing you're looking for is called a "solenoid valve". There are many, many, types, so dig in and do some research.

Agreed, at least initially. If you need to communicate, I would either use various shields (WiFi, Ethernet, etc) for the Arduino, or connect to a computer over serial and have it act as a go-between.

Thx, but cost is not really a primary concern right now, and I already have a Raspberry Pi available. More importantly there's some deep learning stuff going on as well, so the Raspi is necessary, and might be replaced with a Jetson at some point. If i need to use the Arduino as well for some reason, then i will, but i really hope i can keep things less complicated. I may have oversimplified my post to avoid writing an epistle.

Thank you. I saw those, but didn't realize they were what i was supposed to be looking for. It'd have taken me ages to realize.

Awesome! Thx alot. The selection is great, and there's alot of technical specs available. I'm pretty certain this will help me narrow down my options.
