Working on the prototype stage for the OLED MQTT controller I had to make some decisions. One of them was that the MP121 capacitive touch sensor wasn’t going to cut it.
I just wasn’t convinced that it would be able to work reliable through a few mm’s of plexiglass. So I turned to SketchUp and designed a front a best as I could. Turned out to be quite intuitively and thanks to 3D hubs I had it printed in ABS and on my desk in 2 days.
The slave Arduino and the WS2812b were also ditched in favor of an MCP23017 that is going to run the LEDs and buttons.
Will need to make a new PCB or maybe better a couple of small PCBs interconnected.
The final version will be printed at Shapeways in their Porcelain Ceramic Material.
A wooden IKEA BÅS Display box was used as a case. I don’t really like the color so I’ll paint it with varnish later on to match the woodwork in the rest of the house.
