Definitely have to agree on this as got sent the wrong size coil have a 20mm nail but only 16mm coil and those 4mm seem to make a big difference especially if your aim is a bit off.

Although it looks like budbros' auto method worked very well and I'm not sure how much better actually using the pid equation would be if any better at all.

Hi still relearning calculus. But could do with the preferred temperature you like it set to and if you've had it running how long it took to get there. (I think). But I will get there. Will post something soon as I've learnt everything needed and have the numbers.

Hi Budbro do you have any values you'd like me to plug in to the equation? or are the ones on the graphs your values? Can definitely see why you had problems working this out. I have, no I did have a good understanding of the calculus maths involved ie integration, differentiation but that...

Blimey going to have to brush up on the maths skills it's been a while. Cheers for posting this budbro. I'll post up the numbers as soon as I'm done. probably be a couple of days as definitely going to have to relearn some maths. It's been about 8 years since I did any maths like this. But I'll...

Don't suppose you could post the equation and the numbers you need to plug into the equation. I'll have a go at the maths for you.

Hi agaain trichy don't suppose youve settled on which nozzles and bodies are best for your siphon fed air assisted aero. Have one siphon fed nozzle already plus 2 pressure fed. Currently trying to get away with using siphon fed for the simplicity and its taking me forever to get timer and...

Cheers Trichy for supplying the exact information on your siphon fed nozzles. I will eventually have to upgrade to these from the cheap one I brought. Does the job for now but pretty sure the average droplet size is too small. Great info and details. Been trying to get something going like...

Hi dickhead, I got the compressor and a siphon nozzle but the mist is intermittent lucky it was pretty cheap, dont suppose you could recommend any nozzles and nozzle bodies. Got an arduino and solenoid valve just need to learn how to wire it all up and code the thing now. Plus obviously need...

Hi Trichy, which nozzles and nozzle bodies did you use for your AA aero, I bought a cheap siphon fed nozzle off ebay but can't get a constant output from the nozzle so think I may need to invest in a couple more. The mist drops off even when theres plenty od air going through the nozzle. Any...

Great project, I didn't think the code was finished as it looked like it ended after the setup function and I couldn't see your function in use anywhere so just to check I did a copy n paste. I can now see that it's all there. Brilliant project was thinking of doing subverting very similar bit...

Hi NES, what's the make n model of the plc your going to use, thats got all the digital and analogue I/O ports. This unit sounds great,.would be nice if you could provide a little info on the name or where to get it. Thanks for the info about the PLC in the first place though,.sounds well...

Are you still around, would really appreciate a break down of the parts you used to build your system. Like your messages and nice to meet you btw. Cheers
