This started because I was interested in how the new ESP32 compared against other common Arduino compatible development boards. Source code Arduino sketch on Github The source code is based on this post Direct link to Google Docs Spreadsheet – same as embedded above – feel free to make a copy of the spreadsheet and link it below…
I have modified the Adafruit SSD1306 library to work with the smaller 64×32 OLED Displays that can be purchased here and from various other online suppliers. https://github.com/WaiakeaRobotics/Adafruit_SSD1306 PDF showing proper wiring for OLED Notes (In Chinese – use google translate) from another on modifying the UCGLIB library for this display
These 85x58x33mm cases can be inexpensively sourced from many locations. However I could find no data on the hole layout so here it is! Remember that the clear plastic lid has a smaller ID than the main part of the case as it overlaps in the seal area!! something to keep in mind if you…
I’d say it works well 🙂 very happy, using the ucglib graphics library. It has advantages compared to the adafruit library in rewriting data to the screen in such a way that avoids the entire line flashing on rewrite.

It was definitely time to clean up the wiring inside this laser cutter.. Something that was lashed together as quickly as possible and now has some wiring issue somewhere, best replaced with newer tech. Original double sided hand taped and etched PCBs made in 2004 for my CNC mill project – partly still working 2016

For now this is just a collection of some links and notes.. I have built in the past and plan to rebuild in the future a large multi KW induction heater, but alas too many project syndrome. Build your own: https://markobakula.wordpress.com/power-electronics/500w-royer-induction-heater/ Or buy for $8.55: http://www.banggood.com/5V-12V-ZVS-Induction-Heating-Power-Supply-Module-With-Coil-p-1015637.html
