Arduino based Heated Decal Bath control software
Application of water-slide decals on scalemodels goes a little bit easier if the water is warm.
This project is based on a FDM 3D printed frame and some electronics that controls PCB heatbed of approx 8 Ohm. An external 12VDC/2A power-plug is needed as well. The UI consist of a 0.96" OLED display with 128x64 pixels using the SSD1306 controller, two LEDs and three buttons.
The microcontroller used is a Arduino Pro Mini 5V 16MHz version.
I used the Atom editor with PlatformIO plugin to manage the source-code and it uses the following libraries: EEPROM OneWire DS18B20 U8x8lib PID_v1
