My own reflow controller
Posted: Sat Sep 13, 2014 12:27 pm
Since I want to get back into electronics as a hobby I decided it would be great to have a reflow oven at hand.
Looking around the internet, it seems just about everybody and their mum has created their own controller, so why
shouldn't I join their ranks .
Working from the following base wishes:
-No need for an onboard MCU, so just sticking a full arduino on there will do just fine.
-I don't know which control strategy is bestfor my intended oven, but since it's basically just
a halogen lamp, I decided to go for triac leading edge phase control, should keep the halogen cycle going.
-This is my first time dabbling with mains, so I'll stick a control output for a zero crossing SSR on there just in case.
-Minimal hardware user interface.. will probably run it connected to a pc with a GUI.
Already gathered the following bits:
-SSR
-BT139/600 triacs
-MAX13855 thermocouple IC
-Cheap(ish) thermocouple
Still busy with the design of the thing.. but I'm pretty much done.
Got a bit too creative with the silkscreens, but that's part of the fun.
Killed some time doing up a logo.. let the old country inspire me since I'm on a short holiday in serbia to attend a wedding.
Gotta love old commie imagery.
Here's the chinese 'flavorwave-turbo' style oven I got.. they boast decent ramp-up speeds, especially with slight modification and
only cost 30 euro's delivered to my doorstep. If Mr.T says it's the best, I would be a fool not to buy it, right?
