There's enough room to display 4 temperatures and they can be had for <$10?I think they're also easier to read.... (see image below)Which brings me to the next point:What's your budget for this? Quote2 - yes as aboveSounds like you can mount the LCD & electronics yourself once received.Quote6 - been told a relay isnt the best thing to use, ive been told a fet should be used its solid state or something. but hey im far from an expert.Doesn't make much difference. I'd prefer a relay because it will give you flexibility to use any fan you like down the road.Probably something like this (2 channel to keep the future options open):16x2 LCD:
Are those 12V power supplies?Can the temperature controller/LCD be powered by those?
so where from here int2str?
Quote from: andy_con on Aug 28, 2013, 09:31 pmso where from here int2str?I ordered a 20x4 LCD display and temperature sensors. Should be here in 3-4 days.I will prototype it up and if you like what you see, I'll solder it up and ship it over.
rough idea on total costs?
to be a pain any chance of using different sensor, i should have gave a tad more info on that part.what i plan to do is drill a small hole in the side of a laser module and mount the sensor in there with some thermal paste.
do you have any photos of the complete setup so i can get an idea of size?
