While planning on reorganizing my local network I'm once again wondering how difficult it would be to power all these devices directly with DC. Falling down the rabbit hole of nano sized DC grids and plants.
As I take everything down I think I will inventory the energy usage of each device, and maybe setup some power monitoring when I stand it all back up. That'll give me some numbers to chew on as I think about what a DC system may look like.
Ran down to Schertz, TX today for the San Antonio Radio Fiesta. Passed the test to upgrad my license to the General class!
While I was there I picked up a couple items at the swap. A couple Kenwood radios for VHF/UHF (2m/70cm) from the 80's to use at my bench, and a TEN-TEC 252 power supply to match my old TEN-TEC Argosy.
All truth is one.
In this light, may science and religion endeavor together for the steady evolution of Mankind;
from darkness to light,
from narrowness to broadmindedness,
from prejudice to tolerance.
It is the voice of life that calls us to come and learn.
A single black walnut tree in a kind lady's yard in Smithville, TX will be the sole mother to all black walnut trees reintroduced to Austin's blackland prairie. There are still good folks out there.
I'm starting to realize some of the freedom zigbee2mqtt with the CC2531 (usb dongle in the vid) are giving me in the IoT space.
It's something I've always avoided because I didn't want to have to buy into some ecosystem with a hub that's constantly calling home to the corporate overlords. For testing I picked up a couple zigbee enabled
Phillips Hue bulbs from a big box store, and was able to control them from a home assistant install on my NAS via an MQTT broker. That makes me the overlord!
