Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer Broadcom APDS-9960 digital proximity sensor, ambient light sensor, RGB color […]
UP board is a low cost development board powered by an Intel Atom x5-Z8350 Cherry Trail processor with 1GB to 4GB RAM, and 16 to 64GB eMMC flash that mostly follows Raspberry Pi 3 form factor. AAEON is now offering an “intelligent vending development kit” featuring UP board together with a vending machine controller (VMC) board, a motor for the machine’s internal mechanisms, a camera, a QR Code device, and all the necessary cables, as well as optional WiFi and Bluetooth modules. Some details about AIOT-MSSP01 Mini SSP Vending control board: “Intel Intelligent Vending Based” Motor Control – 24V or 12V, Supports GPIO, DC, PWM Type, Supports up to 160 DC Motors Support LCD and Keypad Feature I/Os Vending machine specific interfaces / standards 1x MDB (MultiDrop Bus) 1x DEX (Digital EXchange) 1x Protocol A (EXE) 1x 1-WIRE 4-channel ADC x 1 4-channel Relay GPIO for 12V & 5V by switch x 1 2x 16 Bit GPIO 1x 8 Bit […]
Gumstix has recently released of three new expansion boards compatible with Raspberry Pi boards and Compute Modules: Gumstix Pi Stepper HAT for 4-wire stepper motors Gumstix Pi Newgate breakout boards exposing all I/Os of Raspberry Pi Compute Module and Compute Module 3 Gumstix Pi Conduit PoE adding PoE support to their LoRa gateway kit based on RisingHF RHF0M301 LoRa concentrator module. The company also offers a custom Yocto 2.2 (Morty) Linux images with support for their Pi HATs and Compute Module carrier boards. Gumstix Pi Stepper HAT The expansion board is designed with the 40-pin header for Raspberry Pi products, and includes Texas Instruments DRV8846, a 4 – 18V, 1.4A stepper motor driver with 1/32 microstepping providing rotational accuracy below a tenth of a degree, and 6,400 distinct positions. The board supports 6 to 36V batteries via a 3-pin headers, includes 256 kbit serial EEPROM, and can be used for printers, scanners, video security cameras, projectors, and other automated equipment.

Robotic exoskeletons are used for medical purposes such as helping with the rehabilitation of stroke patients, or enable paraplegics to walk again, as well as in the work place to assist people lifting heavy objects. While it’s possible to learn about the theory about exoskeleton technology, practical experience may help grasping all concepts better. However, there are not many courses available, and exoskeletons are usually expensive, so Volker Bartenbach, PhD at ETH in Zürich, has decided to created EduExo robotic exoskeleton kit for education purpose. The EduExo hardware is based on off-the-shelf components like an Arduino UNO board, a motor, and a force sensor, as well as a rigid exoskeleton structure and cuff interfaces. The latter is optional as you can get the kit without it, and will instead receive the STL files to 3D print the parts yourself. There’s also a handbook to help you get started in several steps: Exoskeleton Introduction Mechanics and Anatomy – Theory + instructions […]
If you ever wanted to played around with an electric car that’s a bit better than an RC toy, but don’t quite have the cash for a full-size Tesla model, Henes has designed an electric card for you your younger kids that’s controlled by an Android tablet and allows both manual and remote driving.
