possible to design a chronograph?
« on: June 06, 2017, 01:45:30 »
I've been trying to think of a project I can work on and I was wondering if Tinkerforge would work well enough for a chronograph.  I would be measuring the speed of a pellet from my pellet gun and if possible real ammo.  I have been reading around it it seems like the best way to take measurements is with Infrared.  I'm not sure if Tinkerforge could handle the speeds of those projectiles.  Do you think it would work or should I just program an bare Avr or other microcontroller using C?

The problem might be the time it takes for a signal to travel from the sensor on a Bricklet to the Brick over USB to the PC. You You may reckon that that this can take about 1ms.

For calculating the speed of a bullet a 1ms delay may already be too much?
