Ways to measure the speed of a golf ball?

AI Thread Summary
To measure the speed of a golf ball in a putt-putt setting, using standard photointerrupters is suggested, with two emitter/detector pairs placed along the ball's path. Affordable HD video cameras can also be utilized, recording at 30 or 60 frames per second, allowing for frame-by-frame analysis to determine speed. Additionally, apps like speedClock may provide a convenient solution for real-time speed measurement. Setting up graduation marks can aid in accuracy during the measurement process. These methods offer cost-effective alternatives to traditional radar guns for tracking golf ball speed.

Help, I need to find a cheap way to measure the speed of a golf ball in a putt putt type of golf hole and view it in real-time on a PC display? Got any ideas? I thought about using a baseball speed radar gun but thought there must be other good way? Any ideas or have you seen something like this?

Welcome to the PF.

Can you just use standard photointerrupters? Two emitter/detector interruptors placed a foot or two apart along the path of the ball, like where there is a chute only a few feet wide...
 
There are cheap HD video cameras out there, one I use for fishing has a 30 and 60 frams per second record rate. You might check if some of the PC video software can do a frame by frame view. If you set the interval at 30 frames per second, film a stop watch and check. then set up a tripod and film away. You might want to put down some graduation
marks to measure with.
 
Apparently there are apps out there that will do this, like speedClock

Dunno if this will suit your purposes, but there may be others out there that do.

oh, this likely defeats the purpose of any assignment that may be associted with the request. Please ignore if that is the case.

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
