Just to keep derailing this thread, do Brits go around discussing engine power in kW instead of horsepower? If they do, they kudos for being consistent in using SI units.
Here in Aus we do discuss in kW, but it's more fun to say "killer wasps" than "kilowatts"

Arduino polar alignment aid
in DIY Astronomer

Hi @kens, wondering if you had any updates on your project? I'm hoping to get into some landscape astrophotography with my Nikon D7200. I built myself a dodgy-DIY barn door tracker using a stepper motor + Arduino Nano. I tried polar aligning by attaching my phone to the tracker and using the PhotoPills app to point the tracker towards the celestial pole - the accuracy wasn't too bad, but I'm hoping to find a reasonably quick, low-budget method to improve on this and your project looks very interesting!
