Fair warning - mechanical engineer here so this is just my "hobby" to support my other hobbies.
Looking to acquire data at minimum 50KHz - three channels at most. Would like a "hat" for a Raspberry Pi or some other plug in device. I have done a bunch of Googling and have been disappointed in the results. Only needs to be 8 bit data. This will be interfacing with some 3mm break beam sensors for measuring the velocity of a Mach 1 ping pong ball. Would like to acquire the data and display it on a screen for the kids to see. Screen I can handle, just need help with the data acquisition.
