Thanks for clearing that up! That puts sop many peaces of the puzzle in place.

here are the specs of the DC to DC
input voltage form out batteries is 76.8V total pack voltage

output voltage is 13.5v at 300 watts

I need to power both the raspberry pi and a DAC.

New problem with this project. Our DC to DC converter outputs 13.5V 22.2Amps. What can I use to step this down to voltage and amperage usable by the raspberry pi B+. Thanks To power the Pi? I just use UBECs which cost a GBP or two. They convert anything in the range 5.5V - 26V to 5V typically at 3-...

were looking at anywhere form 500 rpm - 5000 rpm. The pulses per second should mirror the RPM/60 so for 5000 RPM the pulses per second would be approximately 84 pulses per second

thanks

Hello I'm very new to the Raspberry Pi world. I am part of the auto shop at my high school where we are building a electric motorcycle. We want a tachometer for the motor which will measure the shaft RPM of the motor. I've been looking in to hall effect sensors and they seem to be the easiest to imp...
