Upgrading Marlin firmware on the Ender 3 Pro

Part 4 of my New Years’ 2024 upgrade posts series … Upgrading my Ender 3 Pro with the newer 32-bit mainboard means I can now more easily upgrade the firmware. I considered trying out Klipper, but since Marlin is what I’m used to (the original 8-bit board was running Creality’s version based on Marlin v1.1.9), …

Upgrading some Ender 3 Pro hardware

For Part 3 of my latest round of upgrades to kick off 2024, I also made some hardware changes to my Ender 3 Pro 3D printer for the first time since getting it back in 2021: installed a new mainboard installed the CR Touch automatic bed levelling sensor installed a new metal extruder assembly replaced …

Upgrading to Bullseye on the Raspberry Pi 4

My two Raspberry Pi 4 Bs (in my HomeTroller Pi and OctoPi) were both running Debian 10 (Buster). I like to be current (as evidenced by my bi-annual Ubuntu upgrades) and realized I’d been lax on the RasPis, both of which were two releases behind. Debian 12 (Bookworm) seemed a little too new, so based on some …

Upgrading the HomeSeer/HomeTroller hardware

My 1st gen HomeSeer HomeTroller Pi was built on a Raspberry Pi 3 B with 1gb of RAM. While this was fine back when I bought it and was just starting my home security and automation re-design and foray into using HS4, recently I’d been having issues with performance and out-of-memory conditions. In 2021 when …

Changing registrars: goodbye Google (Squarespace), hello, Cloudflare!

Last summer, Google announced that it would be shutting down its Google Domains service and selling it to Squarespace. I had a few domains (like this one) registered through Google that I had transferred from DynDNS (which is now owned by Oracle!) back in 2016 and was just going to let the transfer happen and …

Leaving the (Google) Nest

I bought my first Dropcams back in 2014, right around the time Nest (which had acquired Dropcam) was acquired by Google. Then I added the Nest Thermostat in 2016 (which was later replaced in 2021 with a Z-Wave one during an HVAC system upgrade), the Nest Protect smoke/CO detectors in 2018, and finally a bunch …

FITCAMX Dash Cam (EV6)

I’ve been really happy with the FITCAMX dash cam in my RAV4. When my wife got her EV6 last year there wasn’t a similar model available so I ended up getting her the Garmin Mini 2 (which apparently I never wrote about here), wired into her rearview mirror housing with a Dongar USB power adapter. …

Synology DiskStation DS720+

During my recent switch from LastPass to Vaultwarden I was planning on using Docker but then discovered my old (2014) Synology NAS didn’t have the CPU architecture to support it. I was already in the middle of one big winter break project, why not add another? Time for a NAS upgrade! My DS214 started out …
