Turns out there is a DBC standard for defining #CANbus message payloads so I started documenting them for the #bafang motors, controllers and displays https://github.com/kasparsd/besst-reference/issues/3

The #wordpress block editor feels mature enough so what if we focused on distribution and engagement (and community) features instead of full-site editing. The website as the primary consumption and engagement channel has been replaced with dozens of platforms for the past ten years or so. It still has its place but it would be great to see an effort dedicated to this other use-case. https://a.wholelottanothing.org/a-blueprint-of-my-dream-blogging-cms/ via @mathowie

Notes on Sunday tinkering with Bafang #ebike #CANbus https://kaspars.net/blog/bafang-canbus

Notes on USB-C PD65W Adapter and Charger for 18V and 20V Power Tool Batteries https://kaspars.net/blog/usb-c-pd65w-adapter-charger-18v-20v

Need to move an existing @mikrotik #CAPsMAN running on a hAP ac2 to ax2 and the whole wifi-qcom vs. wireless packes thing makes my head spin https://help.mikrotik.com/docs/display/ROS/WiFi#WiFi-WiFiCAPsMAN even after watching the video https://m.youtube.com/watch?v=37aff6d14Xk

There appears to be a new firmware for #Bluetti #EB3A battery — v2053.08 for ARM and v2052.11 for DSP. Can’t find the changelog, though.

I wish it was possible to renew a domain name for more than 10 years…

Turns out my #scrypted #homekit integration broke due to this commit https://github.com/koush/scrypted/commit/90a7e447040d257e39052fc4fc062c480e326163 which changed MDNS advertiser from MDNSAdvertiser.AVAHI when there is avahi-daemon running on the Docker host and volume mapped to /var/run/avahi-daemon/socket

Previously it was running a dedicated instance of CIAO inside the container. Would there be issues with having two MDNS servers on the same network host?

Built this tiny #homelab server rack from leftover plywood — turned out pretty nice. Metal brackets are from Amazon.

What is some open source #maker hardware you have purchased recently?

Yesterday I learned that all recent #Bafang motors and controllers for ebikes use #CANbus for communication. Their #BESST configuration tool https://bafang-e.com/en/oem-area/service/besst/ is an electron app which conveniently includes source maps, so I was able to reconstruct the original #Vuejs source code. I’ve posted my findings on GitHub https://github.com/kasparsd/besst-reference

Finally a good review of the n305 NAS board https://nascompares.com/2024/03/15/the-topton-n305-nas-motherboard-hardware-deep-dive-review/ — information about the actual power consumption to be coming soon from what I understand.

Responded to @kasparsd:

The actual video quality is not great with a lot of background glare and the contrast changing drastically depending on the viewing angle.

Found this 11 inch HDMI and USB-C monitor for 50 EUR that works with Beelink EQ12 (n100) and Beelink U59 Pro (N5105) over USB-C with both Ubuntu and Windows 11 out of the box https://www.aliexpress.com/item/1005005650269591.html #homelab

Responded to @kasparsd:

It is now pulling in images as well 🫰 That should be enough of tinkering for a Saturday morning.

Responded to @kasparsd:

Turns out it was due to a bad conditional — it was checking for “Note” type on activity instead of the activity object.

Ok, who did the networking for the Google’s campus and why doesn’t it work? #homelab https://www.reuters.com/technology/googles-newest-office-has-ai-designers-toiling-wi-fi-desert-2024-03-07/

Responded to @kasparsd:

Well, looks like it didn’t pull in any new content over night.

Responded to @zrail:

@zrail That’s lower than I expected. I have my UPS draw additional 15W on top of the 30W from NAS https://kaspars.net/blog/powerwalker-vi-500-r1u

A 10W source in a 20x20x20in box gives you 6.6W per m2 or 0.33W/m2 at dT=20K which is achievable with 4in of pretty much any insulation board.

Responded to @zrail:

@zrail all the power used by the gear is dissipated as heat so you could build an insulated box to house just the gear and it should keep it warm enough. Do you know the total power consumption?
