DIY SBC cases and SBC Case Builder tool based on OpenSCAD

Since you can’t always rely on single board computer (SBC) vendors to provide a case to match your needs, some went the DIY route. Willy Tarreau designed some laser-cut enclosures with Inkscape for various SBCs, while hominoids went a step further by developing the “SBC Case Builder” tool to automatically generate various types of 3D printable enclosures using OpenSCAD. Willy designed five similar enclosures for Khadas VIM3/VIM3L, FriendlyELEC NanoPi Fire3, SolidRun Clearfog Base networking SBC, Libre Computer AML-S805X-AC (aka “La Frite”), and AAEON UP Board. All cases are available in Inkscape SVG format, and Willy accepts contributions for other boards. You’ll need a laser engraver or CNC router to cut out those enclosures. Hominoids’ SBC Case Builder project attempt to automatize enclosure generation for SBCs using SBC Model Framework written in OpenSCAD. Work has focused on ODROID boards so far, but it should work for other vendors too. The parameters […]

Khadas VIM4 Review – Part 1: Unboxing, kit assembly, and first boot with OOWOW

Khadas VIM4 is a compact Amlogic A311D2 octa-core Cortex-A73/A53 SBC with 8GB RAM, HDMI input and output, WiFI 6 connectivity, and more. You can check our earlier post for the full specifications. The good news is that it will officially launch on May 10. I’ve also just received a Khadas VIM4 review sample today together with accessories. Today, I’ll start by checking out the board, assembling the kit, and trying out OOWOW services to boot OS from the cloud, before testing available operating systems in more detail in the second part of Khadas VIM4 review a little later. Khadas VIM4 kit unboxing I received everything in a blank cardboard package with several small packages inside. Besides Khadas VIM4 SBC, we’ve got a plastic + metal enclosure with screws and screwdriver, two antennas for WiFi and Bluetooth, a USB Type-C power supply, a USB-C cable, an M.2 expansion board, a short […]

OpenScan DIY 3D scanner works with Raspberry Pi, DSLR, or smartphone cameras

OpenScan is an open-source DIY 3D scanner that relies on Photogrammetry and works with Raspberry Pi camera modules, compatible ArduCam modules, as well as DSLR cameras, or the camera from your smartphone. The open-source project was brought to my attention after I wrote about the Creality CR-Scan Lizard 3D scanner. The OpenScan kits include 3D printed parts such as gears, two stepper motors, a Raspberry Pi shield, and a Ringlight module to take photos of a particular object from different angles in an efficient manner. The OpenScan Classic kit above allows for 18x18x18cm scans and comes with the following components: 1x Nema 17 Stepper Motor (13Ncm) 1x Nema 17 Stepper Motor (40Ncm) 2x A4988 Stepper driver 1x Power Supply 12V/2A (5.5-2.5mm plug) 1x Optional Bluetooth remote shutter control for smartphones If you’re going to use the Raspberry Pi as shown on the right side of the image, you’ll also need […]

DIY Raspberry Pi Zero 2 W handheld PC (mostly) makes use of off-the-shelf parts

The Penkesu Computer is a DIY handheld PC powered by a Raspberry Pi Zero 2 W SBC, and mostly comprised of off-the-shelf parts including a 7.9-inch display from Waveshare, replacement hinges for the Gameboy Advance SP, a 48-key mechanical keyboard fitted with Kailh low profile Choc V1 switches, and so on. Penk also happens to have designed the CutiePi tablet with Raspberry Pi CM4, and designed the Penkesu Computer (ペンケース in Japanese) as a side project without having to “worry too much about commercial viability” and as a way to remind himself why he started tinkering. Penkesu Computer handheld PC specifications: SBC – Raspberry Pi Zero 2 W with Broadcom RP3A0 SiP with Broadcom BCM2710A1 quad-core Cortex-A53 processor @ 1.0 GHz, 512MB RAM, MicroSD card slot Display – 7.9-inch IPS display with capacitive touch screen, 1280x 400 resolution, connected over HDMI via flat cable through an Adafruit adapter Keyboard – […]

Raspberry Pi UPS HAT takes two 18650 batteries (Crowdfunding)

Raspberry Pi UPS solutions have been available for years with products like PiJuice Zero, PiVoyager, or LiFePO4wered/Pi+. But the team at SB Components has designed another UPS HAT for Raspberry Pi with a holder for two 18650 batteries. The HAT is designed for 5V operation up to 2.5A, connects with the Raspberry Pi SBC through the I2C bus from the 40-pin GPIO header, and is equipped with a 0.91-inch OLED for information display. UPS HAT for Raspberry Pi specifications: Power Input – 8.4V/2A via DC jack Power Output – 5V up to 2.5A through LDO chip (GPIO header and 2x USB ports) Display – 0.91-inch OLED Host interface – I2C Misc – On/Off switch Battery support 18650 Lithium battery (not included) via holder for two batteries Battery reverse indicator Charging and voltage monitoring via TI INA219 I2C chip Battery voltage balancing with Hycon HY2213 Battery protection IC (Hycon HY2120) Dimensions […]

DIY Pip-Boy wrist computer is equipped with Adafruit Feather RP2040 board

The Pip-Boy is a (virtual) personal information processor found in Fallout post-apocalyptic role-playing video games. But John Edgar Park decided to bring the wrist computer to (real) life combining an Adafruit Feather RP2040 board, a round IPS TFT color display, directional buttons, a joystick, and a battery. The Raspberry Pi RP2040 based Pip-Boy is programmed with CircuitPython and the demo code is a slide-show with navigation controls, but you could obviously adapt the code to your needs. The main components are: Black Adafruit Feather RP2040 board Adafruit Joy FeatherWing adding buttons and a joystick Adafruit 1.69″ 280×240 Round Rectangle Color IPS TFT Display FeatherWing Tripler mini kit to connect the two boards above and the display 3D printed enclosure A 3.7V/420mAh LiPo battery for power On/off switch The design is completed with some headers, stand-offs, screws, and a nylon watch strap. You’ll find detailed instructions with the list of parts, […]

DIY Raspberry Pi Compute Module 4 NAS supports up to four drives

We previously noted it was possible to build a Raspberry Pi CM4 NAS using Wiretrustee carrier board with a built-in Marvell 88SE9215 PCIe to SATA controller and four SATA connectors. But Mebs just created his own Raspberry Pi Compute Module 4 four-bay NAS with his own carrier board equipped with a PCIe socket used to insert a PCIe SATA card, as well as a neat 3D printed enclosure that took 6 days to print. This carrier board design is actually derived from the official Raspberry Pi CM4 IO board with only the interfaces needed for the NAS to make it smaller and fit within the width of a standard 3.5″ hard drive. It was also made as simple as possible because it was Mebs’ first PCB design. This leaves the board with Gigabit Ethernet, one HDMI port, a USB 2.0 port, the PCIe 2.0 socket, as well as some headers […]

Pockit modular Linux computer takes hot plugging magnetic blocks
