Floppy thumb drive integrates Adafruit PyPortal display based on Microchip SAMD51 MCU

Floppy thumb drive

Anne Barela’s Floppy Thumb Drive project houses the Adafruit PyPortal internet display in a 3D-printed enclosure that looks like a 3.5-inch floppy disk, just a bit thicker. The computer-in-a-floppy-disk project runs CircuitPython code to list the first 12 files stored in the flash and can display photos or animations, play audio, or execute scripts. The project consists of three main parts: The Adafruit PyPortal internet display with Microchip SAMD51 (ATSAMD51J20) Arm Cortex-M4F microcontroller @ up to 120 MHz with 1 MB flash, 256 KB SRAM Display – 3.2-inch 320 x 240 color TFT display with resistive touchscreen Audio – Speaker Storage 8MB flash storage optional microSD card (not used in the project). ESP32 for WiFi and Bluetooth connectivity (not used in the project) Sensors – Light and Temperature sensors Misc – NeoPixel RGB Micro USB to USB cable 3D printed files for the front cover, back door, front door, disk, […]

Auspicious Machine

The “Auspicious Machine” may look like a Blackberry phone, but it’s actually a handheld Linux PC with a built-in QWERTY keyboard and a 3.5-inch display that can be powered by a range of system-on-modules (SoM). The computer, whose name can also be translated as the “Auspicious Phone”, can be used as a Linux terminal with GPIO control, and for gaming with Linux distributions such as Batotera or RetroBat with the D-Pad and ABXY buttons found on the device. Auspicious Machine specifications: Supported SoMs Bigtreetech CB1 with Allwinner H616 quad-core Cortex-A53 processor and 1GB DDR4 Raspberry Pi CM4 with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB LPDDR4, up to 32GB eMMC flash Radxa CM3 with Rockchip RK3566 quad-core Cortex-A55 processor, up to 4GB LPDDR4, up to 64GB eMMC flash Banana Pi BPI-CM4 with Amlogic A311D octa-core Cortex-A73/A55 processor with 4GB LPDDR4 and 16GB eMMC flash Storage – MicroSD card socket […]

Raspberry Pi 400 powers dual-display retro-gaming console

DIY Enclosure Raspberry Pi 400 console

“Block after Block” has designed a dual-display tabletop retro-gaming console using plywood edge grain and a Raspberry Pi 400 keyboard PC that allows players to physically face each other during a fight or other gameplay. While there’s a galore of projects based on Raspberry Pi SBCs, the Raspberry Pi 400 keyboard PC is more like a consumer product due to its form factor, but Block after Block integrated the PC into its own retro-gaming console which involved a lot of woodworking skills and installing RetroPie on the Pi 400 device. This DIY project mostly involves spending time in a workshop cutting wood, and once you’re done with this part, it should be pretty straightforward. The following items are required for the project: A Raspberry Pi 400 keyboard PC Two monitors (second-hand monitors will do) An HDMI splitter to mirror the output from the Pi 400 along with a micro HDMI […]

TinyLlama x86 retro computer uses the Raspberry Pi Zero 2 W as a MIDI synthesizer

TinyLlama x86 retro computer

The TinyLlama x86 retro computer board is designed to run DOS games on a DM&P Vortex86EX 32-bit x86 processor and integrates a MIDI synthesizer based on Raspberry Pi Zero 2 running MT32-Pi firmware. Growing up playing games on 386/486-era computers, Eivind Bohler looked for similar recent hardware to play DOS games and after discovering the 86Duino x86 Arduino-compatible board, he decided to use the SOM-128-EX module powering the board to create the TinyLlama board with a Sound Blaster Pro-compatible Crystal CS4237B sound chip and a MIDI synthesizer. TinyLlama specifications: D&MP SOM-128-EX system-on-module with Processor – DM&P Vortex86EX 32-bit x86 processor @ 60 to 500 MHz System Memory – 128MB DDR3 Storage – 8MB SPI flash Storage – MicroSD card socket Video Output – VGA up to 1024×768 @ 60 Hz using the Vortex86VGA module running off an x1 PCI-e lane Audio Crystal CS4237B all-in-one audio chip MIDI synthesizer with Raspberry Pi […]

ODROID-Go Ultra Amlogic S922X portable gaming console and devkit launched for $111

Amlogic S922X portable game console

Hardkernel ODROID-Go Ultra (OGU) portable gaming console and devkit is powered by the same Amlogic S922X hexa-core Cortex-A73/A53 processor found in the company’s ODROID-N2+ SBC. The new model also adds a 16GB eMMC flash for faster storage and increases the RAM capacity to 2GB. The Korean company’s adventure with portable gaming consoles started with the ESP32-based ODROID-Go to celebrate its 10th birthday in 2018. At the time it looked like a side project, but the console was popular enough that they released their first Linux handheld game console with the ODROID-Go Advance (OGA) in 2019, and then the ODROID-Go Super (OGS) in 2020 with a larger 5-inch display, and both equipped with a Rockchip RK3326 quad-core Cortex-A35 processor. The new ODROID-Go Ultra is based on the same design as the OGS model, but with a serious jump in performance, and the ability to support more demanding emulators. ODROID-Go Ultra specifications: […]

DevTerm portable Linux terminal now supports Raspberry Pi CM4 via a $19 adapter

DevTerm Raspberry Pi CM4

DevTerm modular, portable Linux terminal initially designed for modules based on Raspberry Pi CM3 form factor, can now work with Raspberry Pi CM4 for extra performance and memory thanks to a $19  adapter. The Devterm was initially launched in 2020 with a 6.8-inch IPS screen, a keyboard with 67 keys, and a battery module, all connected through the ClockworkPi v3.14 carrier board taking a choice of core modules based on Allwinner H6 or Rockchip RK3399 (now supported in Armbian), besides the Raspberry Pi Compute Module 3 mentioned above. More recently, it also got an Allwinner D1 RISC-V module. The Raspberry Pi CM4 module should bring performance similar to the Rockchip RK3399 module for most tasks, although it may vary a lot depending on workloads, and for regular Raspberry Pi users, software that will be more familiar, and may be better supported. I’ve just a bit surprised it took so long, […]
