Lisperati1000 Lisp portable programming workstation features Raspberry Pi Zero W, ultra-wide display

Lisperati1000 Lisp Programming Ultra-wide display

Conrad Barski (Lisperati) wanted a portable “workstation” to write in Lisp and see all those parentheses. Since there aren’t many devices with an ultra-wide display, he decided to build his own “Lisperati1000” ultra-compact Lisp programming workstation powered by a Raspberry Pi Zero W, and equipped with an ultra-wide 1920×480 8.8-inch display, a compact keyboard made of Cherry Brown switches, and a 4,400mAh dual battery all housed in a 3D printed enclosure. When Conrad first showcased his little handheld computer on Twitter, he first claimed only 3 will ever be built, but think quickly got out of control with the project being featured on Hacker News, and he changed his mind after seeing the popularity of the DIY computer. UPDATE: Due to high demand, I have decided to fund a project to release this as a kit. If you are an electrical engineer and/or know about machining Aluminum, please get in […]

Person Detection on Raspberry Pi Pico with ArduCAM and TensorFlow Lite

ArduCAM is popular for camera-based applications with various boards ranging from Arduino to Raspberry Pi. We also saw the company’s tiny coin-sized Raspberry Pi compatible module 5 years ago. Now, it also supports the newly launched Raspberry Pi Pico for real-time video applications. Raspberry Pi Pico is compatible with the ArduCAM Mini 2MP Plus camera featuring an OV2640 2MP CMOS image sensor that supports automatic image control functions including Automatic Exposure Control (AEC) and Automatic Gain Control(AGC). The camera also comes with an onboard JPEG encoder for image compression. The company has provided a Github repository with two demo applications: a video streaming application and an example for basic person detection with the probability percentage of detection. There is also an option of directly using the UF2 files for flashing with Raspberry Pi Pico, if you don’t want to build the demo from the source code yourself. The application runs […]

Ingenic T40 4K Video & AI Vision Processor mixes MIPS & RISC-V cores with AI accelerator

Ingenic T31 MIPS & RISC-V AI video processor was introduced last year with the MIPS core including SIMD128 Vector instructions for deep learning. The Chinese company has now introduced the new Ingenic T40 processor still with MIPS and RISC-V cores, but also a dedicated 8 TOPS AI engine/CNN accelerator. The new processor is especially suited to smart AI vision application thanks to support for 4K cameras, and 4K MJPEG/H.264/H.265 hardware video encoding, complemented by the 8 TOPS AI engine for computer vision workloads such as people detection, face recognition, object detection, and so on. Ingenic T40 key features and specifications: CPU – Dual-core MIPS XBurst2 @ 1.2 GHz with 256KB L2 Cache, SIMD512 instruction set MCU – 600MHz RISC-V coprocessor AI Engine – 8 TOPS neural network accelerator with 1MB memory pool, support for int16/int8/int4/int2 convolution width Memory – DDR2/DDR3/DDR3L up to 2GB Storage – SPI NOR flash, SPI NAND flash, […]

PICO-PI-IMX7 NXP i.MX7 SBC offered for under $20 (Promo)

TechNexion PICO-Pi-IMX7 single board computer was introduced a few years ago with an NXP i.MX 7Solo or 7Dual Cortex-A7 Intel Edison compatible CPU module, in a form factor similar to Raspberry Pi 3, and supported by Android Things that was still a thing at the time… It looks like Arrow Electronics is trying to get rid of some stock, as the company is selling the Amazon version of the PICO-PI-IMX7 board for $19.58 including free shipping for ArrowPerks members, instead of the usual $120+ price tag. We had written about the PICO-iMX6 module and PICO-PI-iMX8 SBC previously, but never about the i.MX7 version, nor the PICO-PI-IMX7 board, so let’s have a closer look at what the board has to offer. PICO-Pi-IMX7 specifications: PICO-iMX7 system-on-module SoC – NXP i.MX 7Dual dual-core Cortex-A7 processor @ 1 GHz with Cortex-M4 real-time core System Memory – 512MB DDR3L Storage – 4GB eMMC flash Connectivity […]

Raspberry Pi Pico Gets supports for Rust, RT-Thread OS and FreeRTOS

Raspberry Pi Pico Rust RT-Thread FreeRTOS

In January end, we saw the launch of Raspberry Pi Pico equipped with an RP2040 dual-core Cortex-M0+ microcontroller working up to 133 MHz with official support for MicroPython and C. In this feature, we will be discussing the Raspberry Pi Pico’s flexible software support compatible with RP2040 MCU, apart from the MicroPython, C/C++, and upcoming Arduino IDE software support. We will specifically be focusing on Rust, RT-Thread OS, and FreeRTOS support for Raspberry Pi Pico. Rust Code Running on Raspberry Pi Pico Rust language is considered fast, reliable, and secure when it comes to IoT gateways. It also opens up the option for writing extremely low-level code, such as operating system kernels or microcontroller applications. Porting Rust with RP2040 for working with Raspberry Pi Pico was seen in Jonathan Pallant’s Twitter Feed. The RP2040 comes with an external QSPI flash. The internal mask-ROM reads the programs from the external flash […]
