Jerry de Vos’ Plastic Scanner Turns a Raspberry Pi Into a Spectrometer for Plastics Recycling
https://www.hackster.io/news/jerry-de-vos-plastic-scanner-turns-a-raspberry-pi-into-a-spectrometer-for-plastics-recycling-ef6c61b7a64f
Designed for sorting plastic by type, the handheld scanner runs local machine learning analysis on a Raspberry Pi Zero W.
Graduate industrial design engineer Jerry de Vos has turned a Raspberry Pi into a low-cost handheld scanner, which identifies plastic types to ease sorting for recycling — and has taken his place among the winners of the 2021 James Dyson Award.
“The breakout board shines eight individual LEDs with a wavelength of 850, 950, 1050, 1200, 1300, 1450, 1550 and 1650nm,” de Vos explains. “The LEDs have a narrow bandwidth with a full-width half max of 20nm and a tolerance of just 3nm. The reflection from these LED lights can be measured by the sensitive and precise analog- to -digital converter, the ADS1256.”
The Plastic Scanner, then, is effectively a device for infrared spectroscopy — but using a discrete approach that makes it considerably cheaper than traditional lab equipment. “This method is slightly less accurate,” de Vos admits, “but can still identify the most common plastics.
“After the user has turned on the handheld scanner, the screen tells them to push the scanning button once a scan is desired. As soon as the Raspberry Pi recognizes that the button is pressed it sends a command to the breakout board, which starts the scanning procedure. Once the scanning is completed it is communicated back to the Raspberry Pi, which subsequently starts the interpretation algorithm to interpret the sample. Once this is completed the result is shown on the screen.”
De Vos has released details of the project via Wikifactory under the reciprocal GNU General Public License 3.0 with more available on GitHub,

Raspberry Pi TOSLINK transceiver hat
Optical digital audio I/O for Raspberry Pi
https://hackaday.io/project/182641-raspberry-pi-toslink-transceiver-hat
The Raspberry Pi has support for i2s audio I/O. It’s fairly simple to add a S/PDIF transceiver chip and optical audio I/O ports on a hat to allow it to be conveniently used.
The WM8804 is the S/PDIF transceiver chip of choice for this project. Adding a single line to the Pi’s config.txt file, to wit:
dtoverlay=hifiberry-digi
is enough to add support for it.
To be compatible with the driver, the chip needs to be configured in software controlled mode, i2c interfacing, the address has to be 0x3b. This is accomplished with pull-up or pull-down resistors on some of the I/O pins of the WM8804. For the driver, there also needs to be a 27 MHz crystal connected. The i2s I/O pins are connected to the relevant pins on the Pi, and the S/PDIF input and output pins connect to TOSLINK input and output modules.

Seaberry carrier board turns a Raspberry Pi into a desktop PC with 11 PCIe slots
It’s a bit pricey, though
https://www.theregister.com/2021/11/25/seaberry_rpi_carrier_board/
Fancy a Raspberry Pi 4 in a desktop ITX form factor with 11 PCIe slots? The new Seaberry carrier board may make your wish come true – but for a fairly hefty price.
As we mentioned earlier this month, the forthcoming Linux kernel 5.16 will sport better support for the Raspberry Pi 4 Compute Module. This tiny daughterboard plugs into I/O carrier boards, making the Compute Module a lot more versatile than the Raspberry Pi 4 proper.

Raspberry Pi And The Story Of SD Card Corruption
https://hackaday.com/2022/03/09/raspberry-pi-and-the-story-of-sd-card-corruption/
Tales of Raspberry Pi SD card corruption are available online by the fistful, and are definitely a constant in Pi-adjacent communities. It’s apparent that some kind of problems tend to arise when a Raspberry Pi meets an SD card – which sounds quite ironic, since an SD card is the official and recommended way of booting a Pi. What is up with all of that?

The GASPACS CubeSat, which was sponsored by NASA, features a Raspberry Pi Zero computer, a second-gen Pi Camera Module, and a DFRobot Beetle microcontroller to facilitate basic tasks at a low price.
Like other CubeSat devices, the GASPACS CubeSat is quite small—just 10 centimeters wide. Its mission is to test an “aeroboom” stabilization system, which successfully deployed 45 minutes after astronauts tossed GASPACS CubeSat off the ISS.
