Yesterday, I had to go to the bank with the branch located in a building where they closed all doors except one in order to make sure all people were wearing masks, check their temperature, and let them wash hands with alcohol hand gel. Those are good preventive measures to slow the spread of SARS-CoV-2 virus, but in case many people visit a location that’s also time-consuming. I’ve just come across a system that should speed up the process, as it can check forehead temperature of people as they walk by, using a camera and artificial intelligence for face detection, and an IR camera/thermometer to report temperature. Remote AI temperature screening system specifications: SoC/Memory/Storage – Don’t know, but I would not be surprised if it was based on RK3399 since Rockchip often promotes AI use cases for this processor. External Storage – MicroSD card, USB drive Video Output- HDMI 2.0 […]
M5Stack ATOM is a Compact, Fully Integrated ESP32 Development Kit
When working on a project you may need an MCU or MCU board, an external display, a breadboard, and other accessories like sensors and jumper cables. It does the job, but it can be messy. Recently, we wrote about M5Stack M5StickV AI camera, but the company is better known for its ESP32 IoT development kits enabling neater project thanks to hardware that integrates MCU, I/O headers, display, and sensors into an enclosure. Their latest offerings are ATOM series toolkits that come in two versions: ATOM Lite and ATOM Matrix. Let’s have a look at both. M5Stack ATOM Lite Specifications: SiP – ESP32-PICO-D4 system-in-package with ESP32 dual-core processor with WiFi 4 and Bluetooth 5.0/5.1 Storage – 4 MB flash Crystal oscillator and passive components USB – 1x USB Type-C port Expansion 9-pin header with 6 GPIOs compatible with jumper cables 4-pin PH2.0 connector with 2x GPIO, 5V and GND Misc – […]
Onyx Boox Nova 2 7.8″ eReader Runs Android 9.0
We wrote about reMarkable 2 10.3″ e-Paper Tablet running Linux a few days ago, but there’s now another option with Onyx Boox Nova 2 eReader equipped with a 7.8″ display and running an operating system based on Android 9.0. The device comes with an unnamed octa-core processor coupled with 3GB RAM, 32GB storage, support for Wacom pen and touch input, and a 3,150 mAh battery. Onyx Boox Nova 2 specifications: SoC – Unnamed octa-core processor @ 2.0 GHz, but likely Qualcomm Snapdragon 625 found in the company’s Boox Max 3 eReader. System Memory – 3GB RAM Storage – 32GB flash, MicroSD card reader Display – 7.8″ E Ink Carta Plus inductive Wacom + capacitive touch screen with 1872×1404 resolution, 16 shades of grey, and the SNOW Field function to reduce artifacts during a partial refresh Frontlight – MOON Light 2 to use the device in the dark or under poor […]
An Arduino based Open Source Ventilator to Fight against COVID-19?
COVID-19 has disrupted most people lives well beyond the health crisis, with an economic fallout on-going that may lead to a 24% GDP contraction in the US and up to 12% worldwide in Q2 2020, and I assume the consequences may span over several years, so we should do everything to mitigate any effects from the disease. Right now, the urgent part is to handle the health crisis, and there’s a shortage – or soon will be – of medical supplies such as ventilators for people in critical conditions, and if hospitals become full they’ll start refusing admissions of some people even in critical conditions, as it happened in Wuhan, letting people die at home. So there are various initiatives and projects to develop open-source ventilators. First, Innovation Management reports Ennomotive has launched a non-profit online competition for the ideation of low-cost, easy-to-build solutions with the goal of speeding up […]
reMarkable 2 is a $399 e-Paper Tablet with Pressure Sensitive Pen
reMarkable digital notepad and e-reader was unveiled in 2016, and designed to feel like using actual paper sheets. The device came with a single-core Cortex-A9 processor, a 10.3″ E-Ink display with 1872×1404 resolution, and WiFi connectivity to backup your notes and/or drawings to the cloud or mobile phone. The company is now back with reMarkable 2 e-Paper tablet equipped with a faster and more efficient dual-core Cortex-A7 processor, 1GB RAM, a second-generation CANVAS 10.3″ e-Paper display with the same 1872×1404 resolution but lower latency. The second-generation e-Paper tablet also benefits from a thinner design and much-improved battery life. reMarkable 2 specifications: SoC – Dual-core Arm processor @ 1.2 GHz (possibly NXP i.MX 7Dual processor) System Memory – 1GB LPDDR3 RAM Storage – 8GB internal storage good for around 100,000 pages Display – 10.3″ monochrome digital paper “CANVAS” capacitive touch display partially based on E-Ink Carta technology with 1872×1404 resolution (226 […]
4.2″ and 7.5″ NFC-powered e-Paper Displays Work without Battery
e-Paper displays have great readability under sunlight, and only consume power when updated. But their refresh rate is limited, and most displays are fairly expensive. One way to reduce the cost is to completely remove the battery from the display, and update it through NFC providing both data and power. I’ve just found out about that possibility through 4.2″ and 7.5″ displays offered by Waveshare. All you need is a compatible NFC smartphone, or the company’s ST25R3911B NFC Board to power the display and transfer your image of choice. This works best for signs you may need to infrequently update such as menus, daily schedules, conference badges, labels, etc… Waveshare NFC-powered e-Paper display key features and specifications: Screens 7.5″ display 800×480 resolution 2-level greyscale 170° viewing angle Refresh Time – 5s + data transfer time 4.2″ display 400×300 resolution 2-level greyscale 170° viewing angle Refresh Time – 4s + data […]
Omnichip Devkit 2 Features Nordic nRF52832 based zGlue ZiP Multichip Module
We first covered zGlue Integration Platform (ZiP) in 2018 when the company introduced its chip-stacking technology with a fitness tracker based on ZGZL1BA ZiP equipped with chips from Dialog Semiconductor, Analog Devices, Macronix, MCube and others. The concept is similar to SiP (System-in-Package), but zGlue claims the costs and lead times are much lower with the technology. Earlier this year, ZiP was back in the news thanks to Antmicro GEM custom RISC-V/Arm ASIC, and today, I was informed about zGlue Omnichip devkit 2 that is equipped with a ZiP of the same name, and that can be used to evaluate the technology. zGlue OmniChip ZiP zGlue OmniChip ZiP is a multichip module with the following ICs (aka Chiplets) and specifications: Nordic Semiconductor nRF52832 Cortex-M4F microcontroller with Bluetooth LE and NFC connectivity Texas Instruments BQ25120AYFPR battery charger, buck regulator Maxim Integrated MAX86140ENP+ optical pulse oximeter Texas Instruments TMP108AIYFFR temperature sensor Bosch […]
Radiona ULX3S Open Source Hardware ECP5 FPGA Development Board Launched for $99 and Up (Crowdfunding)
Last summer, we wrote about Radiona ULX3S education board combining a Lattice Semi ECP5 FPGA with an Espressif Systems ESP32 WiFi & Bluetooth WiSoC. Designed for a digital logic course at the University of Zagreb, the board is open-source hardware with KiCAD hardware design files released on GitHub, and programmable with the Arduino IDE (FPGArduino) and ProjectTrellis open-source toolchain. At the time, there was only a version based on Lattice ECP5 85F with 84K LUT, but they’ve now made versions with cheaper variants of ECP5 FPGA and launched the board on Crowd Supply. Radiona ULX3S specifications: FPGA (one of the other) Lattice ECP5 LFE5U-85F-6BG381C with 84K LUT Lattice ECP5 LFE5U-45F-6BG381C with 44K LUT Lattice ECP5 LFE5U-12F-6BG381C with 12K LUT System Memory – 32MB SDRAM @ 166 MHz Storage – 4–16MB Quad-SPI Flash for FPGA config and user data storage; MicroSD slot Audio – 3.5 mm jack with 4 contacts (analog […]
