DIY shutter speed tester for Large Format lenses 

Thanks

Anyone here in 2024? I bought an arduino uno, laser, phototransistor and LCD display. The code (cameradactyl) does not work! It freezes, crashes, the shutter speeds are inaccurate, it only shows 40-60/sec. Someone wrote here (Luigi, Javier) that it was modified since then, is there any new, updated code? Also, the video doesn't even mention the lcd oled display, is it already included in the code? (no). Please share recent information who has done it recently, don't let anyone tell me that it works! 3 years old code, my Arduino doesn't work! Someone help me please

你可以讲讲alphax快门的操作吗？网上很少。 Can you explain the operation of the alphax shutter? Very few online.

Are there any details published about the components and diagram?
