Which is the fastest Arduino – ESP32, ESP8266, Arduino Uno, Arduino 101 +Others Speed Test Comparison Chart
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… Continue reading Which is the fastest Arduino – ESP32, ESP8266, Arduino Uno, Arduino 101 +Others Speed Test Comparison Chart
Micropython IDE options
uPyIDE http://pythontutor.com/ – not an IDE but great tools to visualize how code is executed http://espcut.com/ – IDE for ESP8266 NodeMCU, Lua and MicropythonIDE for ESP8266 NodeMCU, Lua and Micropython Windows Only 🙁 but provides a file structure viewer of the MicroPython file system through the serial port.
SSD1306 64×32 Pixel .49″ OLED ER-OLED0.49-1W
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
Plastic Case 85x58x33mm KH-F19 Dimensions
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… Continue reading Plastic Case 85x58x33mm KH-F19 Dimensions
Testing ST7735 128*160 SPI TFT Display
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.
Lightning Arresters, MOVs, Surge Suppression
The following are large 3 lead MOV’s that include a thermal fuse – this fuse will prevent thermal runaway on short circuit failure mode. The 3 lead arrangement also allows an LED indicator light to notify when failure of the thermal fuse has occurred. $4 TMOV25SP115M – 28MM 20KA 170J 115VAC 150VDC – good for 150V… Continue reading Lightning Arresters, MOVs, Surge Suppression

LaserCAD does not bind to correct network interface
LaserCAD using the network interface is a great way to communicate with your laser cutter. Unfortunately the program seems to choose the wrong interface card on my desktop and there appears to be no way to change this besides disabling all other network adapters and running the program again. https://r1ch.net/projects/forcebindip Download the Zip file install… Continue reading LaserCAD does not bind to correct network interface
