Good but not in use yet

I have several godoggo automatic ball launchers purchased here on Amazon.https://smile.amazon.com/dp/B0162O3MYS?psc=1&ref=ppx_yo2ov_dt_b_product_detailsThey come with a micro switch to detect a rubber ball is in position for launch. It is a poor choice for the job. Dog Slobber rain can get to the switch which isn't sealed and cause the launcher to stop working. Also it can get snow and ice on it and the switch can't move. I tried sealed micro switches and that helped the water problem but not the snow and ice. This was one reason I purchased several of these so i could always have a working one out for my dog while repairing the failed ones.So now for this sensor. I mounted it right above where the rubber ball sits to be launched. I adjusted the trim pot on the back so it would detect the ball when in position and then turn off after the ball had been launched. Easy to adjust using the LED on the butt end next to the trim pot. The sensor drives a small relay https://smile.amazon.com/dp/B0BCGD7QVH?psc=1&ref=ppx_yo2ov_dt_b_product_details that replaces the OEM micro switch. My dog gave it a good test today the first day i had it set up and it never missed. She has a burnt orange ball and a blue ball both are hand balls sold here on Amazon. It detected both colors no problem.https://smile.amazon.com/gp/product/B0108OI27A/ref=ox_sc_saved_image_5?smid=A2CVB1QINU068&psc=1The launcher was made for tennis balls but these hand balls bounce much better and now she doesn't like tennis balls much at all.This sensor isn't much more than one of the sealed micro switches i was using.In the photos you can see where the ball sits to be launched with the new sensor directly above it. In the second picture you can see the snow and ice buildup that is where the micro switch lever is located. The yellow circle was the first sensor I tried and it didn't work out. The range on it was only 1-10mm where as this one is now 10-30cm. Third picture shows the mounting bracket I had to make as the new sensor didn't come with one. The scrap of wood will be cleaned up eventually. The rubber boot covering the tail end of the sensor is something I just had in my junk drawer.When the ball rolls down the ramp into the launch position the sensor sees it and starts the motor. The ball gets kicked out and the motor stops in the starting position waiting for the next ball. The test yesterday was about 0-5 F outside and the sensor never drifted or required adjustment. I'm going to upgrade at least one of the other 2 machines when the new sensors arrived.You have to have some shop and electrical skills to make these changes but as you can see from the rest of my review and the reviews others have made there are some issues. Right now my biggest complaint it no spare parts. I've broken one spring so far and had already requested some spares a couple of months ago so I had one when I needed it. The motor and gearbox are not available from the manufacturer or anywhere else I can find so if that fails you are SOL.
