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 […]

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 […]

IP67 mini PC targets harsh environments and marine applications

We’ve covered plenty of Whiskey Lake-based mini PC‘s and SBC‘s, but most of them are made for the home or the office, except for some designed with a wider temperature range for industrial and factory environments. But Stealth is going further with WPC-905 IP67 waterproof mini PC that’s completely sealed and fanless making it suitable for harsher environments, including marine applications. The rugged computer comes with a choice of Intel Celeron and Core processors and supports variable DC input from 9V to 48V DC via an M12 connector. Stealth WPC-905 IP67 mini PC specifications: SoC (one or the other) – all from the Whisky Lake Embedded family Intel Celeron 4305UE dual-core processor @ 2GHz with Intel UHD Graphics 610; 15W TDP Intel Core i3-8145UE dual-core/quad-thread processor @ 2.2GHz / 3.9GHz (Turbo) with Intel UHD Graphics 620; 15W TDP Intel Core i5-8365UE quad-core/octa-thread processor @ 1.6GHz / 4.1GHz (Turbo) with Intel […]

AI digital signage system combines Apollo Lake SoC with Myriad X AI accelerators

Digital signage players were traditionally used to display photos and text, play some videos, or PowerPoint presentations. But like with so many other devices, they can also be enhanced with artificial intelligence with, for instance, facial recognition enabling more personalized information, weather detection showing targeted advertisement (umbrella when it rains, sunglasses on sunny days…), and other data collection. IEI IDS-310AI fanless AI digital signage system can enable these types of features thanks to an Intel Celeron J3455 Apollo Lake processor combined with two Myriad X VPU’s, and the ability to drive three displays through HDMI. IDS-310AI digital signage mini PC specifications: SoC – Intel Celeron J3455 quad-core processor @ 1.5GHz / 2.3GHz (Turbo); 10W TDP System Memory – 1 x 204-pin DDR3L SO-DIMM, 8 GB pre-installed Storage – 128GB SATADOM, MicroSD card slot Video Output – 3x HDMI 1.4b ports up to 3840×2160 @ 30Hz each Audio – 1x Mic […]

MutantC v3 open hardware DIY UMPC works with Raspberry Pi and compatible SBC’s

FOSDEM 2021 open-source developer event will take place online later this week, and yesterday we compiled a list of talks, with one entitled “MutantC PDA introduction – open source and hardware PDA shell” piquing my interest. The talk will be about the third revision of the hardware which allows you to create your own UMPC or handheld computer powered by a Raspberry Pi SBC or other compatible single board computers including Asus Tinker Board S, PINE H64 Model B, Banana Pi BPI-M4B, among others. MutantC v3 is versatile and highly customizable as can be seen from the specifications highlights: Supported SBCs – Raspberry Pi Zero, 2, 3, 4 and compatible. Arduino for keyboard – SparkFun Pro Micro 5v/16Mhz or SparkFun Qwiic Pro Micro – USB-C Display – 2.8-inch, 3.5-inch, or 4-inch “GPIO” LCD such as AdaFruit PiTFT 480×320 display Custom PCBs for display, mainboard, and thumbstick Expansion External 12-pin “docking” […]

FOSDEM 2021 Online February 6-7 – Hardware, Embedded & IoT talks

FOSDEM is an open-source developer event that takes place on the first week-end of February every year in Brussels, Belgium. Every year except this year, as due to COVID-19 restrictions, FOSDEM 2021 will take place online like most events these days. The schedule has been up for some time, and today I’ll look at some of the interesting talks mostly from the Embedded, Mobile and Automotive “virtual devroom” but also other tracks. Saturday, February 6, 2021 13:00 – 14:00 – From Reset Vector to Kernel – Navigating the ARM Matryoshka Long gone are the times of executing the OS in-place from memory-mapped flash upon reset. A modern SoC now comes with complex mask ROM firmware, with driver, filesystem, protocol and crypto support for loading… yet another bootloader. In his talk, Ahmad follows this chain of bootloaders until the kernel is started, stopping along the way for RAM setup, peripherial initialization, […]

Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier board

Wiretrustee SATA board Raspberry Pi Compute Module 4

Broadcom BCM2711 processor comes with a PCIe interface that is used for the USB ports on the Raspberry Pi 4 SBC, but that is exposed through the board-to-board connectors of Raspberry Pi Compute Module 4, aka Raspberry Pi CM4, and allows all sort of designs. So far we’ve mostly seen this PCIe interface used for M.2 expansion slots on devices ranging from industrial computers to carrier board such as Piunora or Gumstix Raspberry Pi CM4 development board. But Wiretrustee had a different idea and designed carrier board with Marvell 88SE9215 PCIe to SATA controller and offering four SATA connectors to build a 4-bay NAS with Raspberry Pi CM4 module. Wiretrustee carrier board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) chip tested at a write speed of ~220MB/s […]
