Nixie Clock #3

This is my 3rd Nixie clock.  I obtained some Burroughs B-5870ST tubes and wanted to make a clock with them.  These are awesome quality tubes made in England.  The mesh is super fine and the numbers are very well formed.  They are nice and bright and supposedly ultra long life. I also wanted to incorporate HV5530 chips for driving the tubes. ...

Wall Pluggable Nextion Screen with WiFi

After the last screen experiment I wanted to try a Nextion screen.  These screens are somewhat interesting as you load the GUI onto the screen module itself and interact with the GUI objects programatically from your microcontroller device (in my case an ESP8266).

I also wanted to make it a bit easier to view and use so made the 3D printed...

Wall Pluggable LCD Touch Screen with WiFi

This is primarily just an experiment with a LCD Touch screen that can be plugged directly into a wall socket.  This is using a cheapo touch screen with the ILI9341 display driver and XPT2046 touch driver.

Future iterations will involve mounting directly into a wall, various size displays as well as different display types.

I made a board to...

RFID Door Access V2.0

I made this RFID door system over a year ago and it has performed flawlessly for over a year and still going.  It was the first time I made one of those things so now it's time to improve it a bit.  The improvements are mostly to do with the PCB I made to mount the Pi 3 on and the dual relay module and nice pluggable terminal blocks.

The...

Cross compile Qt for Raspberry Pi (OpenGL)

I wanted to do some touch screen GUI projects based on Raspberry Pi 3 and various touch screens with an aim towards making more "stand alone" interfaces to my automation projects.  I wanted to be able to use QML based applications so that required OpenGL support.

This is more for my own reference so I can reproduce a working environment.  I...
