It's a happy feeling to get a harvest this time of year, even if it's tiny. Definitely a crop I'll be growing in future Winters. The cool weather keeps them very mild.
Experimenting with automating a small oil heater in the cold frame to take the edge off some of these cold February mornings. Wired up a GFCI outlet with a Zigbee controller that I have talking with my Home Assistant installation.
Using this as practice for a thermostat project I've been thinking about for the house.
Fantastic interview with @neauoire on Future of Coding!
I especially love the discussion about workflow mentality. Taking tasks that you have endless motivation to do and directing them to things that you may not be as motivated/inspired to accomplish.
Anyway, its absolutely worth a listen:
Fully Charged was a lot of fun today! Got to see the Rivian truck, and talk with one of the battery engineers. It was very impressive. However, I found myself drawn to the e-bikes and classic cars that had been given an EV retrofit. I left feeling like we're really on the cusp of EVs being ubiquitous.
After more sleep and less beer I came to my senses. I do want MQTT here, and I simply needed to use something like telegraf to get the data over to influx. Starting to come together now!
Success getting temp and humidity data from two off the shelf 433mhz sensors (one in the garden, and one in the cold frame). Then piping that to MQTT. Using an RTL-SDR dongle, a small dipole, and rtl_433.
It was only after this initial excitement that I realized it probably makes more sense to send this directly to influx db. 🤦♂️
Book Selection, US Pol (I guess?)
As I'm wrapping up some lingering reads from 2019 I think I've settled on "Fear and Loathing on the Campaign Trail" as my first book of 2020. Somehow I haven't read it yet, but as this year's madness continues to ramp up in the US, it seems like the time is right.
If you happen to be curious what I've been reading lately I keep a book log at https://electro.pizza/bookshelf/
This is just mind-boggling.
"The Daniel K. Inouye Solar Telescope has produced the highest resolution observations of the Sun’s surface ever taken. ... The cell-like structures – each about the size of Texas – are the signature of violent motions that transport heat from the inside of the sun to its surface."
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.
