> Compared to other embedded boards that I have, this one is surprisingly well documented; given you find the right webpages (list at the end). The vendor page itself is in a rather typical state, where an online translator occasionally comes handy to translate Chinese into something I understand 😉 But then, there is the really nice sunxi community wiki with has all extra information that you need.

> For the device itself, some months ago I decided to get this one mostly because of the reasons price and delivery date. However, it has a big disadvantage for me when I use it for testing the KDE Yocto layers: There is only a 2D GPU on the board (namely a “G2D” unit) for which also no Kernel drivers are present at the moment (except those from the Kernel source blob by the device vendor). However, for all other parts there is impressive community work. Most notably, coming with Kernel 6.2, there is finally the HDMI driver support that made the above picture possible.

> Unfortunately, I do not expect any Plasma or KDE application running on the Nezha board in the sooonish future (at least not accelerated via the G2D chip)… Yet, if you recall, at FOSDEM 2019 Alistair already demonstrated Plasma running on a HiFive Unleashed board, using an expansion board for graphics. Finally, there is right now another very interesting and not too expensive RISC-V board becoming available with on-board 3D GPU and it is already on my shopping list… I am looking forward to 2023 🙂

> Last week we attended the RISC-V Summit in San Jose. Traction in the RISC-V ecosystem is accelerating faster and faster. The embedded world has shipped 10’s billions of RISC-V cores collectively over the last few years. Qualcomm has silently shifted control and security cores that are not exposed to the user since the 2020 S865 chip. This has enabled them to ship a total of 650 million RISC-V cores! Andes and Codasip are each at over 2 billion RISC-V cores shipped, Western Digital ships over a billion RISC-V cores a year, and even Apple is converting some non-user-facing functions to RISC-V!

> Once a week, millions of people set out their trash cans next to the curb for collection the following day, which many consider to be extremely annoying or laborious. So rather than manually dragging out the garbage and recycling bins, the YouTuber known as Max Maker decided to build a system that could automate the task at the touch of a key fob button.

> Max’s idea involved creating a single track that would span from the back garden area all the way down the driveway to the curb. From here, a train consisting of several flat carts with wheels underneath would be connected together in addition to a single locomotive cart at the rear. The first version of the locomotive used a windshield wiper motor, controlled by an Arduino Uno and motor driver board, to rotate a pair of rubber wheels along the lower track. However, the lack of power from the windshield wiper motor combined with the lack of grip from the wheels meant the heavy weight of the loaded trash cans could not be moved uphill.
