Beagle-Pi Emulator is a Raspberry Pi HAT adapter for BeagleBone Black (Crowdfunding)

Beagle-Pi Emulator BeagleBone Black Industrial

We recently reported the Raspberry Pi boards were getting really expensive due to a lack of supply, and the problem has gone on for while without a clear idea when the issue will be resolved. This does not help Raspberry Pi HAT manufacturers, and for instance, Sequent Microsystems has made Raspberry Pi HATs over the years most models with multiple relays, but also others for temperature sensors, and others automation applications. One solution would be to use compatible boards like ODROID-C4 or Rock64, but Sequent Microsystems found out the BeagleBone Black Industrial was well-stocked by various distributors, and instead, they designed the “Beagle-Pi Emulator” adapter to use Raspberry Pi HAT on the Texas Instruments Sitara AM3358 board. An adapter is needed because the BeagleBone Black boards are equipped with two 46-pin headers instead of the 40-pin header on Raspberry Pi SBC’s. The expansion board routes I2C, SPI, four serial […]

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 […]

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

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 + […]

Round color LCD board comes in Raspberry Pi RP2040 or ESP8266 flavor (Crowdfunding)

RoundyPi Roundy with Raspberry Pi RP2040

Roundy is a board with a 1.28-inch round color LCD with 240 x 240 resolution that is offered with either a Raspberry Pi RP2040 MCU or an ESP-12E WiFi module, with the variants respectively called RoundyPi and RoundyFi. Both boards come with a micro USB port for power and programming, a button for flashing the firmware, and six pins with power signals and four GPIOs. One difference is that the Raspberry Pi RP2040 board includes a MicroSD card for data storage. Roundy specifications: MCU / module RoundyPi – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 256KB SRAM RoundyFi – ESP-12E module with ESP8266 microcontroller @ up to 160 MHz with 160KB SRAM, 4MB SPI flash External storage (RoundyPi only) – MicroSD card socket Display – 1.28-inch round LCD with 240 x 240 resolution, 65k colors; GC9A01 SPI display driver. (It appears to be that model) […]

Inkplate 6COLOR – A 5.8-inch e-paper color wireless display (Crowdfunding)

Inkplate 6COLOR is a 5.8-inch color e-paper display equipped with ESP32 WiSoC to provide WiFi and Bluetooth LE connectivity, and programmable with the Arduino IDE or MicroPython. We’ve covered Inkplate ESP32-based e-paper displays since Inkplate 6 was launched in 2019, and since then the company introduced a larger model and an upgraded variant with a touchscreen display and higher resolution. But so far, all were grayscale models, and Inkplate 6COLOR is the first to come with color, or more exactly 7 colors. Inkplate 6COLOR specifications: Wireless module with dual-core ESP32 processor, Wi-Fi 4 & Bluetooth 4.0 (BLE) connectivity External storage – MicroSD card socket Display – 5.8-inch, 600 x 448 e-paper display with 7 colors (Black, White, Red, Yellow, Blue, Green, Orange) 128 DPI 25 seconds refresh time (manufacturer); tested by Inkplate: 10 to 11 seconds USB – 1x USB Type-C port for programming and power Expansion – Headers for […]

MIPI CSI-2 v4.0 adds features for always-on, low power machine vision applications

While MIPI CSI-2 standard was first introduced in 2005 as a high-speed protocol for the transmission of still and video images from image sensors to application processors, the standard has evolved over the years, and the latest MIPI CSI-2 v4.0 introduces features to better support always-on, low power machine vision applications, high-resolution sensors, and high-dynamic-range automotive image sensors. The main changes for v4.0 include support for a two-wire interface (MIPI I3C) to lower cost and complexity, multi-pixel compression for the latest generation of advanced image sensors, and RAW28 color depth for better image quality and an improved signal-to-noise (SNR) ratio. MIPI CSI-2 v4.0 highlights: Always-On Sentinel Conduit (AOSC) – Enables always-on machine vision systems with ultra-low-power image sensors and video signal processors (VSPs) continuously monitoring their surrounding environments and having the ability to wake up their more powerful host CPUs when specific events happen. Some use cases include laptop/tablet-based face […]

Raspberry Pi 4 to support Network install to a blank MicroSD card

The Raspberry Pi 4 will soon be able to install Raspberry Pi OS without the need for external hardware to flash the image. Raspberry Pi Network install will allow users to install a blank MicroSD card into their board, which will trigger the launch of Raspberry Pi Imager on the Raspberry Pi, and flash the image downloaded from the Raspberry Pi website. So far in order to install Raspberry Pi OS, you had to download Raspberry Pi Imager on a computer or a working Raspberry Pi, insert the MicroSD card into the host, and flash the image, before moving the MicroSD card into the Raspberry Pi board. This works just fine for most people, but if the Raspberry Pi is your only computing device, as may be the case in developing countries, that does not work. Network Installs may also speed up the installation process in the classroom where multiple […]
