  1. Here we can see the different stages of the #battery test period, and recharging after.

    From the left; the pulse stage, were the voltage varies from 12.7V - 14.4V.

    Then we see the test period, where the voltage drops until the battery reaches 50%.

    Now charge stages; bulk (ramping up to 14.4V), absorption (keeping 14.4V), analyze (check if dropping below 12V) and float (keep 13.6V). After 10 days of float the pulse stage starts again.

    #CTEK has this well documented in their user manuals.

  2. Three voltage levels are measured in the alarm system: 5V, 12V auxiliary and the battery voltage.

    A drop in the 12V auxiliary is used to detect a mains power failure.

    The battery voltage is used to estimate battery level, this is done with a dictionary of voltage to percentage where the missing values are interpolated with scipy.

    Once a month a battery test is performed, where the charger is stopped, and the battery voltage monitored until it reaches 50%.

  3. Using my oscilloscope to debug yesterday I (again) realized that I need to get a new one. The one I have is about 20 years old.

    Anyway — that motivated me to cleanup the electronics desk and replace the ESD mat. Only to realize the new mat is a bit short. So I guess I'll be ordering a new one.

    The desk is spotless at least 🧹

  8. It looks like I've also found the reason why the voltage measurements by the was so unstable.

    Simply a user error — wrong size load capacitor, mounted too far away from the voltage reference. Soldered on a new voltage ref. with load and input capacitors, very close and correct values this time :)

  9. I've spent the last few days working on my security system. This house used to have phone outlets here and there, I've repurposed some of those for a hidden buzzer/sounder.

    One in the 2nd floor den, and one in the main living room. They can do two sounds; continuous 970 Hz and 800 to 970 Hz sweep 1/s.

    Still have the "homemade" buzzer in the entryway. Going to replace that as well :)

  10. After only a few evenings' work — I am getting close to seeing my desk surface again 🥳

  13. On my security alarm: I will be replacing all motion sensors with — they seem to be more reliable, have better battery life, short cool-down and I like the mounting options better. 3D printed corner mounts!

  14. On my #RaspberryPi security alarm: I will be replacing all #Aqara motion sensors with #PhillipsHue — they seem to be more reliable, have better battery life, short cool-down and I like the mounting options better. 3D printed corner mounts!

  15. The is up, with 4xNVMe (mirror special device, Intel Optane ZFS SLOG, and datastore). 2x8 TB HDDs, and 2x25 Gbit NIC, with cooling.

    Now to configure the ZFS pool, and I need a switch.

  16. I'm using an old 2 and a DS18B20 probe to accurately measure outdoor temperature. Value is sent on to @homeassistant, and displayed on our digital calendar 👍 blog.cavelab.dev/2024/11/rpi-o

  17. Using @homeassistant I'm setting the clock on our system once a week — to prevent it from drifting. blog.cavelab.dev/2024/11/set-k

  18. It only took me 30 minutes to implement , and it produces nice looking results right out of the box. Amazing! blog.cavelab.dev/search/
