PCB

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. To fix the sensor, I used adhesive tape, which is normally used to mask walls when painting, in order to get sharp edges. This tape can be removed easily and still sticks sufficiently. I designed the case in Autodesk Fusion 360.

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. Of course, this is a pity, but also a new challenge.
