Retro-style computer features 5-inch round display, Framework laptop motherboard

Ubuntu 22.04 retro computer round display

After completing a DIY Raspberry Pi Zero 2 W handheld PC earlier this year, Penk Chen has designed another, rather odd but cool-looking, DIY computer. The “Mainboard Terminal” is a retro-style computer with a round display powered by the mainboard found in Framework modular laptop. The computer has been tested to work with Ubuntu 22.04 out of the box with just a few configuration tweaks for the display, but other operating systems should also work considering the mainboard is based on an Intel Core  i5-1135G7, i7-1165G7, or i7-1185G7 Tiger Lake processor. There are four main off-the-shelf electronics components: Framework laptop mainboard ($399 and up) OLKB Preonic Keyboard MX Kit V3 key ($140) 5-inch round LCD with 1080×1080 resolution plus its HDMI adapter board (550 RMB = about $82) So most of the work consisted in designing the enclosure, and Penk released the STL design files on Github under an MIT […]

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 […]

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

OpenScan DIY 3D scanner Raspberry Pi

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 […]

Creality CR-Scan Lizard 3D scanner works on black objects, offers up to 0.05 mm accuracy (Crowdfunding)

Creality CR-Scan Lizard 3D scanner

When we first looked at 3D scanners a few years ago, products that provided decent results were fairly expensive. But at the end of last year, we covered the Revopoint POP 2 color 3D scanner that appears to offer good scans at a relatively affordable (~$420) price point. Creality, more known for its 3D printers, has now introduced the CR-Scan Lizard 3D scanner with a similar or even lower pricing point, an accuracy of up to 0.05mm, support for scanning of dark/black objects, as well as an optional color kit to scan objects with full colors. Creality CR-Scan Lizard specifications: Accuracy – Up to 0.05 mm Single capture range/area – 200 x 100 mm Point distance – 0.1 to 0.2 mm Working distance – 150 to 400 mm Minimum scan volume – 15 x 15 x 15 mm Scan speed – Up to 10 fps Light source – LED + […]
