I think this is still useful as a TrueNas setup

that CSI-2 filter is really pain in the ass to place on the board and soldering.

I've gone a bit off the deep end and added more columns and functionality.

Anyway, here's 49 Pico form-factor compatible boards compared in a table. PRs welcome.

Kinda fun debugging this to be honest

Basically PFM noise coupling to the enable pin driving circuit.

Love the esthetics for these two CMOS sensor

Try to remove the Bayer layer while the camera is still on to see what actually happens:
My conclusion is that to remove the microlens you to remove them and DMSO doesn't help, but the to remove Bayer filter you need DMSO + mechanically scratch it

First time seeing a UWB module with more than one antenna, kinda neet.

It is using chip called GT1500

Every time I went back to Taiwan I always revisit the electronics store in Guanghua Market.

Yeap, still looks the same for like +10 years.

What a mess

A couple of simple + easy board to end this year.

Geeeeeee

Adding some retimer to the board just in case.

Also something I just realized, typically I2C don't have much distance but HDMI ran the I2C signals through the cables directly?

How the fuck am I able to squeeze these in

4-lane MIPI through HDMI works!

Though you do need the HDMI cable that can do ethernet-over-hdmi so you have the 5th differential pair

Let's just test if the signal works first

I should have adopt 10BASE-T1S earlier....
Probably building a RP2040 + LAN8651 or finally move on from RP2040 and have some MCU that actually have ethernet MAC

It is interesting that I can't create a username with underscore but hyphen.

Fun fact: Taiwanese official english translate name on the passport will have hyphen in the first name. Which is kind of annoying for some paper work in the US that doesn't supports hyphen in the system.
