Raspberry pi balistic chronograph

Sat Jun 24, 2017 4:41 am

Ok so I want to build a balistic chronograph for my archery but also for measuring bullet speed.
I was intending to use an arduino but it's memory limitations might not do what i want, I have a few unused A and B boards I never got around to using and figure that is an arduino can measure down to .000004 seconds perhaps a Pi can too?

My question is this, can a raspberry Pi measure in the micro second range information analog or digital from its i/o pins?

For sensors I plan to use photodiode boards that can be had cheaply from flebay and for a screen I was thinking of a 16x2 LCD, storage perhaps a second wright only card slot if that is at all possible and lastly if it all works some kind of wifi web page interface to display the data on a tablet or phone.

Firstly Don't quote me on this - I am not the expert you need....However, I believe the Arduino would be better for the real-time part of your project, then you could link it via serial or USB to a computer (pi or other) to record/analyze the results at less than real-time speed.....

May help...
