RISC-V Pinout
There are two RISC-V computers on my desk – photos eventually – and they are moving towards “just work” state, but they do occasionally swerve back into the default state of single-board-computers everywhere: there’s a serial port and you’re gonna like it.
From work a few years back with all the Pine64 boards, I have a handful of USB-to-serial converters (and just ordered another one from Pine as a backup), but getting the pins right is always a pain. I’ve considered wiring up better connectors, but never really gotten around to it.
As a stop-gap, I’m going to post (possibly for my own benefit as a backup easy-to-find resource) pinouts for the StarFive VisionFive V2 and the Pine64 Star64 boards. Now that I’ve written this down, I can finally remember “6=GND, 8=TX, 10=RX”.

PureBoot Framebuffer Boot Support
The latest release of PureBoot, Release 27, now boots memtest86+, Debian netinst, and other OSes that rely on framebuffer output!
We worked with the Heads team to implement this change upstream, and it is now in our latest release. Update your firmware with our update instructions!
If you’ve ever tried to boot from PureBoot, and the system seemed to hang after “Starting the new kernel”, this was often the cause. The OS was booting, but it couldn’t display anything.

This recycling bin sorts waste using audio classification
Although a large percentage of our trash can be recycled, only a small percentage actually makes it to the proper facility due, in part, to being improperly sorted.

VBox is like an AI-powered Pandora boombox
Discovering new music is difficult, making it a frustrating experience for both listeners and services. Identifying what one person liked about a specific song is a challenge when music is so subjective.

2023 Cyberdeck Challenge: Reviving The First Notebook Computer
At first sight upon seeing [Don]’s HX2023 cyberdeck project one might be sad at the destruction of a retrocomputer, but in fact its classic Epson shell comes from a pile of spare parts left after restoring many other of the classic HX20 notebook computers to working order. The result stays true to the original but gives us so much more in the shape of a Raspberry Pi, and it’s worth cracking it open to see what components make this happen.

LuckFox Core3566 – A Raspberry Pi Compute Module 4 alternative that sells for $24 and up
We’ve already seen Rockchip RK3566 system-on-modules that follow the Raspberry Pi Compute Module 4 with the likes of Pine64 SOQuartz and Radxa CM3. But there’s at least one more Raspberry Pi Compute Module 4 alternative based on the RK3566 SoC with the LuckFox Core3566 going for as little as $23.99. I found out about the new module after checking out the upcoming Orange Pi Compute Module 4 (another CM4 alternative based on RK3566), and the LuckFox Core3566 is offered with 2GB or 4GB RAM, an optional 32GB eMMC flash, and an optional WiFi 5 and Bluetooth 5.0 module.

Micro RP2040 is a tiny Raspberry Pi RP2040 module with a USB Type-C port, 28 castellated & through holes
SB Components’ Micro RP2040 is a tiny module based on the Raspberry Pi RP2040 Arm microcontroller with up to 23 GPIOs and a USB Type-C port for easy powering and programming. Ever since the Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller was released, companies have been making tiny modules based on it. Some come with a USB Type-C port such as the Pimoroni Tiny 2040 and the Adafruit QT Py RP2040 boards, while others focused on providing a smaller form factor for soldering only with design such as the RP2040 Stamp or the minuscule 12x12mm Femto module.
