Hi, I haven't gotten around to the implementation yet (hopefully this month I'll have time to draw and print everything..), I have two questions following up on the discussion: regarding the diagonal layout of sensors and lasers, is that not a good design proposal? I was counting on a universal...

Hi, it's up to you, for me, the postage is the price of a beer :] And thanks for the project update, I'll try writing to the SD card out of curiosity, but manipulating the SD card will be more complicated for me than copying the values from the console.

Hi Niglyn, it's possible. I didn't examine it in detail, I just printed it at your request and quickly took photos with my mobile phone. If a lower print speed and higher print quality are set, the prints will look significantly better. If you want, send me your address and I'll send you these...

This week was extremely busy, but I managed to quickly print four 3D models from Git at the beginning of the week. The printing was just for testing, with relatively high speed and below-average quality, using ASA material. It was just an experiment to see if the dimensions would fit. I won't...

I have to admit that from a practical point of view, I have no experience with storing data on an SD card or USB mass storage in the case of ESP. With ESP8266 or ESP32, I have always solved everything using MQTT and storing data in InfluxDB. I only reacted to the technical solution if it was...

IMHO there is SD card slot placed on touch LCD :] However, the ESP32 S2&S3 lines can also handle USB OTG, so data read/write is possible. However, you need to solve the problem of powering the board in some other way.

Hi Niglyn, If no one gets to it faster, I'll print the part for you next week and try it on the LCD to see if it fits properly. I might be able to add the part to an ongoing print, but I can't guarantee that, the printer is running almost non-stop right now. Do you want to use any special...

@Niglyn: You're welcome, , in post #555, you asked for name suggestions, so I tried to create a prompt for various AI. How you ultimately name your tester is up to you. Learning to model in 3D in a CAD application is a bit of a challenge, but it's generally useful in life. I wish you good luck...

Hi, I've never used ESP8266 with Arduino IDE. In my case, there was no reason for that. For home automation, I used ESPEasy firmware - it's a really great piece of art for this usage :] But you are right, in this case, it doesn't matter. ESP8266 has only one CPU (which is also used for wireless...

Hello, that's great, I'll see if I can upload the mentioned script to the ESP32 I'm using with the 'activated license' in the IDE, or maybe it would be simpler to use one of the older ESP8266. I have a few of and use them for testing. For now, it's probably not necessary to add functions to the...

Hi Jonathan, thanks, that could help, thank you! I intend to create a separate sensor module that is independent of the measurement module. This would allow me to easily swap out the ESP32 for a breadboard with an Arduino and test the alignment of the lasers and sensors.

Hi @Niglyn, Thanks for clarifying. I'm still in the design phase, currently focusing on another project (digitizing negatives), so there's still time to think about the optimal design. As for adjusting the laser beam position, it's simple: I like things precise, so in this case, I want a...

Hello in the New Year, I thought I had somehow broken this thread ;] .. In any case, I wanted to ask if anyone has already dealt with micro-adjustment of laser modules, how to precisely aim them at sensors. I have two solutions in mind, but both are quite complex, and it's possible that there's...

I've been thinking about possible solutions and this configuration came to mind: There will be 5 lasers, similar to the drawing above. The center laser will always be on and can also be used for single-sensor measurements. An on-off-on switch will toggle between the two outer lasers for 35mm...

OMG, please excuse my stupidity, I've always only looked at the shutter side only, that's really embarrassing :/ I just measured my Kiev-88, the maximum diagonal of the lens mount is 57.7mm... Do you have any ideas for a technical solution to measure the entire medium format shutter? Besides...
