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.

Plastic Case 85x58x33mm KH-F19 Dimensions
by Chester Lowrey • • 0 Comments
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…

Testing ST7735 128*160 SPI TFT Display
by Chester Lowrey • • 0 Comments
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.

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…

LaserCAD does not bind to correct network interface
by Chester Lowrey • • 0 Comments
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…

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
