I agree that the 3B+ was the best Pi but for other reasons:
The Pi 3B+ had the perfect balance between performance and price with the performance being good enough at the time.
Design flaws at launch. Remember the Pi4 CC1 & CC2? POE getting pulled from the market?
Pi5: 5V 5A USB-C??? There is now 45W USB-PD (@15V) that would be compatible with generic PSUs but they went proprietary with 5A@5V.
They put big customers first and let everybody else starve during the shortage. This forced me to alternatives and I have to say they work just as good and cost less.
Jacking up retail prices: Even Intel x86 is now cheaper than a Raspberry Pi.
Right now looking into bang for the buck workhorses with a small footprint/build volume. A description that fit the Prusa mini+ perfectly in the past, but it feels like Prusa is a dinosaur that hasn’t moved with the times....
3D-model collections like Printables or Thingiverse are awesome. Required (ASAP) a CPU socket cover to ship the motherboard. Found it online and 15 minutes later I had the part on hand.
Three years ago I looked into properly wiring hotends with quick toolhead swapes and came up with this: Combining the entire hotend wiring into 3x shielded 4-conductor cables (thin cables for small drag chains with tiny bending radius) and options to terminate the shield. The static side features an USB-port to retrofit...
Wood stoves are a major problem. As soon as it gets cold in Germany, air pollution rises from below 5µg/m^3 to 20-100 µg/m^3 and stays there for months (in this particular area).

Please, use adequate ventilation (with a heat exchanger if you need to keep A/C in the room) if you’re going to be resin printing inside. I don’t want to see all of you guys get cancer from this hobby.
Let’s say the chemicals aren’t healthy. Disclaimer: RTFM (MSDS and technical datasheet) and consult with professionals.
There are a few issues here at play. One major issue is that repeated exposure has a risk of sensibilization. Once this happens there is no way back. Your life will change.
The consumer industry has already moved. I remember explaining to Anycubic sales what an MSDS is and why I need it (if you need a good argument in such conversations: REACH). These days you can download it on their website.
To this day the packaging might not be CLP conform. At least their marketing got better: Water washable has now a section about waste treatment but plant-based resin is still advertised as “low odor and safe to use” or “truly environmentally friendly”. Worst of all they still suggest that the odors are safe to breathe as everything is soybean-based: The truth is they aren’t and neither is it soybeans. What once was soybeans is heavily modified.
Sadly this is not just an Anycubic issue.
Btw. If you use Anycubic though resin: According to their MSDS they switched the product and kept the name the same (approx. 2 years ago).
They screwed up with the most critical group. To cite Steve Ballmer: “developers, developers, developers, developers”. Now tools like bot banning are gone.
Some moderators have stepped down or stayed till they were banned but in large they gave in. As nearly all posts in r/modnews have under 20% upvote ratio the mods are still not happy (e.g. 17% upvotes, 83% downvotes for the r/place announcement and comments are by large negative).
Btw. If you want to hurt Reddit: Post good content on Lemmy and cross-reference it on Reddit.
Btw. Lemmy won’t replace Reddit. This might be hard but it’s the truth and it might be the best for Lemmy as a big platform has a different flair compared to how Lemmy is right now.
