Oh my, many thanks for this most detailed advice!

One more question if I may. Let’s say I already have the pi wide lens that I got with intent to use with the HQ, would that lens fit on the CM 3?

It looks like it won’t fit a GameCube since it’s attachable to the sides of the Switch like a joycon.

Nintendo is generally only backwards-compatible by one generation (example: Wii can play GameCube games but not N64 games), but there’s at least three remastered games in Super Mario All-Stars that are from older generations.

If you have a Switch emulator (I have no idea where to find that), it might work on a PC.

As VisionFive is a competitor to the RaspberryPi foundation but they actually have a product you can buy. Again the problem is most is made for ARM not RISC-V but as you explained it will be relatively straightforward to use as the same GPIO count and connectors.

So the Camera module should work with their board when the environment is made for RISC-V not just for ARM. I am hoping it will be but i do not know how hard it will be as i don't know RISC-V programming.

I would suggest camera module 2 or 3 not HQ. Mostly as you don't need 2028x1520 but slower recording speed and/or streaming video speed. 1080p is good enough. Having 60 fps is most likely better than 40 but that is just me. How high they both go is also relative to how high you sent the resolution. module 3 can do 120 when 640x480 and HQ can do 120 when at 1332x920.

Unless you already got it I would go with module 2 for your use case. As it isn't that much worse than 3 and more compatible.

Here is a list of comparisons.

Camera module 3 vs Camera module 2

The camera module 3
pros:
1080p 60hz record though software might limit you to slower
Better color reproduction

cons:
weights more by 1 gram being 3 grams of weight ( unsure if 1 gram is a lot of a little for your set up)
requires more space on the vertical axis
ONLY compatible with the modern libcamera software environment and not the legacy closed-source camera stack

The camera module 2
pros:
supports 1080p 47frames per second though quickest at 240p at 207frames per second
generates smaller files
color reproduction acceptable for your use case
cheaper
lighter at 3 grams instead 4 grams
is compatible with both the legacy closed-source camera stack and modern libcamera software environment
physically thinner than camera module 3

cons:
It does not support 720p
End of life is sooner though still well supported and as it is open source end of life will just apply to hardware not software
have to manually adjust the camera when moving it physically

Camera module 3 vs Camera module HQ

Camera module HQ
pros:
2028x1520 at 40 frames per second

con:
physically bigger at 38mm x 38mm x 18.4mm not including the lens
you need a external lends for it to be better than the camera module 3
more expensive at 50 USD before you but the lens

unsure about compatibility with software

​

Camera module 3
pros:
faster record at 1080p at 60fps
better color reproduction
weights less how much depends on which lens you use with the module HQ
cheaper
physically smaller at 25mm x 24mm x12.4mm

con:
doesn't support as many lens
only goes up to 1080p not higher

An easy project is to set up a flight tracker in your own home! https://flightaware.com/adsb/piaware/build/

I did it with my old Raspberry Pi because I was desperate to do something with it. The extra parts (antenna and USB signal converter) are like less than 40 bucks if I remember right. Took me like an afternoon to get it all setup. You contribute data to FlightAware and in exchange you get free Enterprise membership (like 100s of dollars/year). You can also set it up so you contribute to FlightRadar24 as well, with a similar membership incentive. I go on a lot of business trips so it's fun to have access to all the extra flight data and keep track of where my plane is. Also, with FlightAware there's a specific web page where they show you exactly what your antenna is detecting. It's really cool to see that I'm tracking some international flight at 35,000 ft and hundreds of miles away all from my apartment haha

TL;DR: It's a fun easy project requiring few extra parts. However, once it's set up there's not much to do with it except check on it.

Invest in better R&D to ease the manufacturing of boards. That's one idea of many.

Are you implying that nothing can be done to accelerate the manufacturing of boards?

Are you implying that Raspberry pi fondation is already at the top maximal optimisation possible when it comes to board manufacturing?

The demand still exists, the supply still doesn’t. Same thing happens with shoes. Individuals will buy a pair and look to flip because there is money to be made. Even if scalpers are prohibited from buying in bulk, scalping will still occur.

The solutions to the availability issue are to either increase supply, or raise the price. One of those is obviously preferable to the other.

It's worth an email but it looks like they've recently removed the "For Educators" section from the web site. Redding between the lines on their December supply chain blog update, I'm guessing they are reserving everything for industry needs and no longer guaranteeing stock for education.

I'd still fire off an email because it takes 10 minutes and they are wonderful learning tools.
