The Adafruit_SSD1306 library doesn't work with my SH-1106-based display. For one, Rocket Scream's TinyReflowController is using a 0.96' SSD1306-based dual-Color OLED display, while I only has a monochrome SH1106-based 1.3' OLED display.

There are several reasons that I did not use Rocket Scream's code directly.

It published its software used for the TinyRelfowController under the Creative Common license in its github, my software is largely based on Rocket Scream's work, but it is not just a clone of its repository or a simple fork, as I did quite some major re-write, and therefore I named my code as TinyReflowControllerV3, the link to the source code can be found at References below. Rocket Scream from Malaysia has been selling Tiny Reflow Controller that it produced for many years. Another button is used to for start/stop of the reflow process. One button is used to select the profile of Lead or Lead-free reflow profile, as Lead-based solder has lower reflow temperature than Lead-free temperature. MCU get the temperature reading from the thermocouple via SPI, information is sent to the OLED display via I2C.

The schematic for my DIY solder reflow controller consists of the Arduino Leonardo as the MCU, an 1.3' SH1106-based OLED display, two push buttons, the MAX31855 breakout board, an LED, and three 2N3904 transistor driving circuits for driving a SSR, a buzzer and a fan, although the schematic include a driver for controlling a fan but eventually I didn't install any fan. The link to the schematic can be found at the References section below. Converting UYue preheater into a Solder Reflow Controller I removed the Power Jack of the Leonardo as it height and size blocking the MAX31855 breakout board a little bit. One thing that I purchased (cost about $3.5 including shipment from AliExpress) and mounted behind the prototype board is an I2C MAX31855 thermocoupler breakout board. For the front of the prototype board, I try to make it cleaner and simple, the wiring behind the board is mess but that will be covered by the Leonardo. I started by using an ATTin圓217 board that I developed a while back as MCU because I had plenty of it, but I realised that the size of the prototype board is just slightly bigger than an Arduino Leonardo board, and I had an Arduino Leonardo board which I hardly used for the past several years, so I changed the design by making the the prototype board acts as an Leonardo shield that can be mounted on top of Leonardo.

The prototyping board will like a front panel with an OLED display as well as buttons for the control, the screw terminals for connecting the thermocouple and SSR, plus other connectivity will be hidden behind the board. My idea is to mount all the components on a 60x70mm prototyping board which can then be mounted on the casing to cover the hole due to the removing of the original controller. What need to be replaced is the controller. Most part of the UYue preheater can be re-used, such as the casing, the heating platform (which is the whole reason why buying it and hacking it), the thermocoupler and the Solid State Relay. I don't want to purchase a reflow controller, I want to use whatever parts I already had with minimum purchase, which means that I have to design my own circuit and write my own code for the solder reflow. He uses an off-the-shelf reflow controller for his modification. I get the inspiration from Digicool who published a 3-episode youtube videos of his teardown and modification. The controller has an on-board AC/DC converter and a 7805 5V regulator. The UYue 946-1010 preheater is a quite simple machine, it has a microcontroller board that consists of a Nuvoton's N76E0003AT20 chip which is an 8051-based 8-bit MCU, a FOTEK SSR-25DA Solid State Relay(SSR), a thermocouple and three 100-W heating elements. Your use of any information or materials on this Tiny Reflow Controller is entirely at your own risk, for which we shall not be liable. Disclaimerĭealing with high voltage is a very dangerous act! Please make sure you know what you are dealing with and have proper knowledge before hand. It costs another US$20 shipping cost for shipping from China to Singapore by air in about 10 days. There are several size of UYue preheaters that can be purchased from AliExpress, I bought the smaller version which has a heating platform of 100mm x 100mm for about US$25. UYue 946 preheater is a small preheater that is often marketed as a tool for separating the layers of mobile phone display during mobile phone repairing, or for replacing the faulty LED on SMD LED plates. This article talks about how I hack a UYue 946 preheater and convert it into a solder reflow hot-plate.
