Anyone compare GY-30 vs. TSL2591 light sensors?

Anyone compare GY-30 (BH1750FVI) vs. TSL2591 light sensors? I am getting different results in reference to lux levels from these sensors when using the same light source. I expected some difference, but not a big difference, the difference is more than 50 or even 100% difference in lx reported. The ...

Re: PiZeroW - Reboot and shutdown no longer work

Did this ever get solved? Shutdown --reboot 1 (reboot after 1 minute)... works in part, the PiZero W shuts down... but it never restarts. Pretty ugly issue.

Re: udev for stable MAC address: Raspberry Pi Zero gadget mode

Who is the idiot, yes I say idiot, that thought a dynamic MAC address by default is a good thing? This is a horrible issue for network security design and control systems. The default SHOULD BE STATIC, have total human intelligence for network device design dropped sharply recently?

Re: Wifi Reconnect on drop

It would be better to use 'dhcpcd' if you are using Raspbian based on 9.0 or later, since dhcpcd is a bit smarter than ifconfig. I would also try a connection test before using dhcpcd so you only try to reconnect if needed. For example: 1) Ping your router, if found, exit 2) If router not found, run...

Correct spacer offsets for other boards, not Pi?

Anyone know what the correct spacer, offsets are for the various other PCB boards? The Pi has 2.75mm holes, so a M2.5 spacer or stand off works fine for the Pi, but the HC-SR04 (Sonic Sensor), or the PIR (Motion Sensor) have even smaller holes. Does anyone know what diameter these other sensors use?...
