E3K all-in-one wireless bio-sensing platform supports EMG, ECG, and EEG sensors (Crowdfunding)

E3K ESP32 bio-sensing platform

Over the year, The maker community has designed several platforms to monitor vital signs with boards like Healthy Pi v4 or HeartyPatch both of which are powered by an ESP32 WiFi & Bluetooth wireless SoC. WallySci has designed another all-in-one wireless bio-sensing platform, called E3K, that also happens to be powered by Espressif Systems ESP32 chip, and can be connected to an electromyography (EMG) sensor to capture muscle movements, an electrocardiography (ECG) sensor to measure heart activity, and/or an electroencephalography (EEG) sensor to capture brain activity. The board also has an extra connector to connect a 9-axis IMU to capture motion. E3K main board which the company refers to as “Data Communication and Processing Unit” (DCPU) comes with the following specifications: Supported wireless board – ESP32-DevKitC with ESP32-D0WD-V3 dual-core 32-bit LX6 microprocessor, up to 240 MHz, Integrated 520 KB SRAM, 16 MByte SPI flash. 2.4 GHz WiFI 4, and Bluetooth […]

CrowPi2 Raspberry Pi 4 Education Laptop Review

CrowPi2 Raspberry Pi Laptop Review

I started my review of CrowPi2 Raspberry Pi 4 Learning Kit a while ago and at the time I showed content from the kit and its first boot. I’ve now spent more time with this very special Raspberry Pi 4 laptop and will focus this review on the education part, namely CrowPi2 software, but will also look at thermal cooling under stress with and without a fan, and try to install another Raspberry Pi compatible board inside the laptop shell. CrowPi2 Education Software It’s quite important to read the user manual before getting started as there are a few non-intuitive steps you may have to take. First I assume the wireless keyboard would just connect after pressing the power button, but it did not. The user manual explains the RF dongle is inside the mouse, and once you connect it you’ll be able to use the keyboard that has some […]

UPX-Edge BrainFrame Edge AI DevKit Targets Smart Video Analytics

UPX Edge Embedded Computer

AAEON UP Xtreme Edge (UPX-Edge) is a rugged embedded computer built around the company’s UP Xtreme SBC with a choice of 15W Whiskey Lake-U processors ranging from Celeron 4305UE to Core i7-8665UE, and optional Intel Movidius X AI accelerator cards. We previously noted the company had launched UP Xtreme Smart Surveillance kit integrating Milestone video management software (VMS) and SAIMOS video analytics software to the embedded computer. AAEON has now partnered with another company – AOTU.AI – to announce the launch of the BrainFrame Edge AI Developers Kit (DevKit) aiming to help developers and system integrators to rapidly create and deploy Smart Vision applications. The solution relies on UP Xtreme Edge mini PC fitted with an Intel Core i5-8365UE processor and 16GB RAM, 64GB eMMC flash, and two Intel Movidius Myriad X VPUs. We’ve also gone through Up Xtreme Edge specifications, so let’s instead focus on the software. This is […]

Using an Old Cassette Tape to Enclose a Battery-powered Raspberry Pi Zero

Raspberry Pi Zero Cassette Tape Enclosure

If you’re old enough you may have a stock of old cassette tapes that may or may not work anymore. The good news is that if you have time on your hands, you could recycle those as a Raspberry Pi Zero enclosure, including even other components like a small battery, battery charging board, and display. That’s exactly what Martin Mander did with his Cassete Pi IoT scroller project that receives notifications via IFTTT service and displays them as scrolling text on a small display connected to the Raspberry Pi Zero W. Here’s the detailed list of components used in this project: Raspberry Pi Zero Wireless Pimoroni LiPo SHIM LiPo/LiIon power supply shim for Raspberry Pi boards Adafruit Micro Lipo charger board with micro USB port Pimoroni 11×7 LED Matrix 150 mAh Li-Polymer Battery Cassette Tape DPDT Slide Switch Vibration motor Once assembly is done, you can flash a Micro SD […]

MEGA-RTD Raspberry Pi HAT Offers up to 64 Resistance Temperature Detectors (Crowdfunding)

MEGA-RTD Raspberry Pi HAT

Sequent Microsystems like to make stackable Raspberry Pi HATs. After their stackable 4-relay board allowing for up to 32 relays controlled by a Raspberry Pi board, the company has now launched MEGA-RTD 8-channel RTD Raspberry Pi HAT enabling up to 64 resistance temperature detectors via 8x MEGA RTD board stacked on top of a Raspberry Pi board. If you haven’t heard about this type of temperature sensors, we wrote a post explaining the advantages and drawbacks of resistance temperature detectors last year. Basically, those temperature sensors contain a resistor that changes resistance value as their temperature changes, and support much wider temperature ranges than traditional temperature sensors such as DHT22 while keeping a <0.1°C accuracy. The price of the sensors themselves is similar to traditional sensors, but the total price is more expensive since they require extra hardware to measure the resistance/voltage value. MEGA-RTD key features and specifications: MCU – […]
