What do you call a "piece of glue-stick" ? |

Hot glue gun sticks. I used 3 cm of it. Heat the end up and stick it to the
LED.

Did you create something like a 'light-strip' out of glue? I have to test this! Edit: did anyone try something like this? |

It has been a couple of busy months since I was last able to work on this project. I was facing some misinterpretation of some figures (#2423) due to heavy reflection. I tried your solution with the clue stick, which worked ok'ish. Then, the misreadings started again. To get rid of the reflection, I tried this: https://de.aliexpress.com/item/1005003186394069.html This seems to help to reduce the reflection. Unfortunately, I still got the misreadings. I probably will have to provide some training data... :-( |

Aus der Zeit der 3D-Kinos gibt es die 3D-Brillen. Da ist auch Polarisationsfilterfolie in den Gläsern. |

I didn't try polarization foil but I had - by far - best results with plastic packaging foam. |

I also had a lot problems with reflections on my meter with dark round digits. I ended up with a 3d printed shroud to bring the light source closer to the surface without external lights or fibre optic cables. That way the light can only pass below the shrouds lip and won't come from an angle that reflects back to the camera. The downside of this solution is, that it only works for meters with exclusively digital figures. |

Hi eveyone. I have tested a lot of diffusers/contraptions to get the onboard LED to shine light evenly onto the digits.
So far a piece of glue stick worked best. Simply cut a 3 cm piece and then stick it with onto the LED (the circular, cut surface).
Works like a charm.
