Re: Spirit Schematic

gpvillamil I think the simplest solution for the existing boards to get the Arduino reset available to the RasPI GPIO would be to take one of the unused pins (like GPIO25) and jumper to the reset pin (pin 5) on the 8-pin header P14, which is near the front of the Spirit board, towards the pan/tilt h...

Re: Forward-thinking: Jessie or Stretch? Python 2 or Python 3?

I agree with your ratinoale for C marckarasek... but C isn't for everyone. I thought kevin's intent was for an education platform for younger coders, for which I think python is the right start, they can then branch into C if they need the performance.

kevin? This is your baby...

Re: Forward-thinking: Jessie or Stretch? Python 2 or Python 3?

I compiled OpenCV 3.4 against both Python2.7 and Python3.0 bindings simultaneously. That's even more future-proof... and just as easy to do.

Re: Power use of LEDs - some observations

Very astute observation. For power consumption purposes, capping the values of the NeoPixels to 127 is a really good idea. I'm not sure if it quite cuts power consumption in half... but it gets close. There may be some color shifting, though, because our eyes are more sensitive to some colors (green...

Forward-thinking: Jessie or Stretch? Python 2 or Python 3?

Kevin et. al.: The cards that came with our Spirit Rovers had Raspbian Jessie installed... The first thing I did was flash my card with Raspbian Stretch from 11-29-17 from "the mothership" at https://www.raspberrypi.org/downloads/raspbian/ . Similarly, as I"m going through your python...

Simple way to monitor your Spirit Rover's syslog

HI all --

If you want to actively monitor your /var/log/syslog to look for problems (or any other log for that reason), use the following command from a terminal:

Code: Select all

tail -f /var/log/syslog

Re: A way to clone your Pi's SD card without removing it

This tool also allowed me to take an install that was on a 128GB cheap card (unreliable in the Pi) and downsize an already-working install to a 32GB higher-quality SanDisk card... so it has more utility than just backing things up.

A way to clone your Pi's SD card without removing it

Hey all, I just used a very useful tool today for cloning a Raspberry Pi, using the Pi to a USB SD card reader, so we don't have to remove our SD cards to back up our Spirit Rovers... The tool is here, and it's pretty well documented: https://github.com/billw2/rpi-clone Kevin: we should probably inc...
