I hate to start out this way, but I didn’t make much progress with my chronograph work. I did give it a shot, but I couldn’t get a viable reading. Mind you, I only shot some pellets in the basement.

My current operating theory is that the light is too dim and the projectile is too small to register. I understand this device to work with two optical sensors. I think that it sees the projectile pass over each sensor and then calculates the time difference. So, if it is not being seen then it doesn’t calculate.

There were some warnings about using it in low light, and this situation definitely fits. My particular model actually has LED lights on the background reflector (the white plastic strips). I think that the lights are an attempt to extend the useful light and projectile size. Yet they didn’t seem to work on my initial attempt.

I have plans to test my son’s nerf gun just to see if something will register before I get too carried away. If I can get some measurements, then I can experiment with the light conditions. There is also technical support because it is supposed to work with pellets.

End Your Programming Routine: Due to the fact that I am out of town this week, I am not going to make any progress while I am gone. I haven’t totally decided but this would be a good weekend to also go to the range. Likely, since I am just getting back I will need the time to do stuff around the house. But, I could probably squeeze in some trigger time outside, if the weather permits.
