Never good enough ...

And because I can never, ever, leave hardware alone … my second rpi, the one I do hardware tests on, looks like this tonight:
That’s a cobbler extension to get the gpio header out of the case, a DS3231 RTC, and a light sensor connected.
The DS3231 is pure playing … the rpi does not get its time from the internet, I disabled that on purpose. It’s relying strictly on the RTC module. I can power it off for as long as I want. When it gets turned back on, its clock would be accurate without needing the internet. But since other modules rely on getting data from the internet, this was done just for the fun of it.
The light sensor on the other hand, that is going to eventually be something I will use on my mirror. The current output on the sensor looks something like this:
So why a light sensor? I will leave that up to your imaginations. :)

I needed one so I can dimm my LED light if it is night and make it brighter if not! :)

Ding ding ding! That’s exactly why I got it. :)
