Neil, Im wondering which MLX90614 to get as there are different FOV's 90° 70° 35° 10° . I have a couple of trees near my observatory and im wondering if...

Hi George, I've thought about this too. The one thing about trees is that they should be a constant. It might mean that the difference in temperature between...

Maybe something simpler is called for :) Im thinking the IR way especially in the cloudy UK might be overkill and you'd just endure continuous false alarms....

I thought it was a little pricey, but it does include the ATMega 328, so it is a combination MCU/sensor, you save the cost of an Arduino. I guess you could...

Hello, I had no problems setting up the easy driver, and the ascom driver, but my stepper (pm42l-048-nbx5) seems to have problems being driven. After the ascom...

I will have a look tonight but i think the bit you changed is for a stepper connected via another driver chip like the 293 and not via the easydriver. I will...

It would probably be down to how you wired the stepper up, probably got a couple of wires crossed so it just sits there oscillating. Check which wires...
