To simplify the reading and evaluation of my electricity meter, I have built a reading head using an ESP32 board and a TRCT5000 infrared sensor. Unfortunately, I still have an old, so-called “Ferraries electricity meter”. But this one has a turntable with a red mark. This makes X revolutions per kWh, in my case 75. By the duration of a revolution the momentary consumption can be calculated then. For the sensor, I then 3D printed a housing to mount it on the meter and align it.

Why all this? The ERCF Speedboard is my first self-made board for my 3D printer. I was motivated by the ERCF Easy Board ( https://github.com/Tircown/ERCF-easy-brd ). In the 3D printer itself (a Voron 2.4) I used the mainboard is the Fysetc Spider v1.1, which I recently changed from Klipper to RepRap firmware. There was no particular reason for this, I just wanted to try it out. However, I have lost the ability to communicate with the ERCF Easy Brd as a result.

To calibrate the JVC X5000 projector, there is a software from JVC called Autocal. Unfortunately this does not work together with the colorimeter i1Display Pro. But there is another software project ArgyllCMS which can use the sensor. So I thought some time ago, why not write a wrapper that connects the open source software with the software from JVC. The result is a DLL file, which pretends to be a Spyder colorimeter, but calls the ArgyllCMS in the background.
