Reflow Oven Shield

Design by: 4671

A Arduino Uno shield to control a Reflow oven: You need 1 x OLED Scree http://imall.iteadstudio.com/im130625003.html 1 x Arduino 1 x Thermocouple 1 x 12-20v PSU 1 x Solid State relay capable of switching your toaster oven (25A) The thermocouple stage is built around the $0.10 LM358 opamp in the same fashion as the SSID http://dangerousprototypes.com/2014/05/20/simple-soldering-iron-driver-ssid-with-arduino-pid-control/ and you can reuse portions of that projects code for this The Solid state relay is switched using a mosfet from the 12-20v input allowing the use of non-logic-level relays All parts values are printed on the silkscreen so you dont even need assembly instructions If you need schematics/sources see https://github.com/openhardwarecoza/OPHW-EL-3DPElectronics/tree/master/ReflowOvenController Arduino sketch is maintained in the same repo
