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 […]

TI Innovator Hub Connects MSP432 LaunchPad Board to TI Graphing Calculators
I remember when I was in high school we all had those TI calculators to cheat enhance our chances of passing exams, but Texas Instruments has now launched what it calls TI-Innovator Hub based on a MSP432 LaunchPad board that connects to some of their graphing calculators and allows student to program and control external hardware through their calculators. Innovator Hub hardware specifications: MSP-EXP432P401-ET TI LaunchPad Board 3x input ports, 3x output ports, I²C port Breadboard connector with 20 labeled pins USB Mini USB Port (DATA port for connection to a TI graphing calculator, or a computer running TI-Nspire CX software) Micro-USB port (POWER port to connect to external power source) Misc – Red LED, RGB LED, Light Brightness Sensor, and speaker Enclosure The hub can then be programmed using TI-84 Plus CE (TI Basic language) or TI-Nspire CX (Lua language) graphing calculators. It’s a bit like playing with Arduino […]
ASUS Tinker Board is a Raspberry Pi 3 Alternative based on Rockchip RK3288 Processor
Regular readers may remember MQMaker MiQi board, a $35 (and up) development board powered by Rockchip RK3288 quad core ARM Cortex A17 processor, based on Raspberry Pi 3 form factor, but much faster according to benchmarks. Sadly, the board’s crowdfunding campaign was not that successful, possibly because of the “its’ a 2-year old processor” syndrome. But now, Minimachines has found that ASUS has designed a very similar board, dubbed Tinker Board, with an extra WiFi and Bluetooth LE module, audio jack, MIPI DSI connector, and a few other modifications. Asus Tinker Board specifications (bold highlights and strike-through show differences with MiQi board): SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2GB LPDDR3, dual channel Storage – 8 or 32 GB eMMC flash + micro SD slot Video output & Display I/F 1x HDMI 2.0 up to 3840×2160@60p […]
Outernet Introduces Standalone & DIY Internet Satellite Kits for C.H.I.P Board, Raspberry Pi 3 Board, and Laptops
Outernet goal is to bring knowledge and/or emergency info to places without Internet either to remote places, or where Internet has been temporary shutdown due to natural disasters or political reasons through a satellite feed. In some ways, it works like a typical FM radio, but instead of receiving audio, you’ll get data. The first hardware was based on WeTek Play TV box, and called Lighthouse, but they now have a DIY kit that will work with Next Thing C.H.I.P, Raspberry Pi, or Laptops running Windows 7/10 or Linux, as well as a standalone Outernet Satellite kit including C.H.I.P Allwinner R8 development board. Let’s first check out “Basic Outernet DIY Kit” comprised of three items: L-Band Antenna Frequency: 1525 – 1559 MHz (Center frequency: 1542 MHz) 8dbi 4″ SMA Male connector Dimensions – 12 cm x 12 cm x 1.5 cm Weight – ~100 grams RTL-SDR Blog Software Defined Radio/Tuner […]
Evive is an Arduino Compatible Platform with Enclosure, Lots of I/Os, Buttons, and an 1.8″ Display (Crowdfunding)
Engineers at Agilo Technologies, an Indian startup based in Kanpur, Uttar Pradesh, felt that the wire mess often produced while learning or prototyping with Arduino boards could be an issue, and it was easy to mis-wire your setup, so they’ve decided to create a user and student friendly Arduino compatible system with many of the items you’d normally use with Arduino board such as buttons, probes inputs, an 1.8″ color display, headers for ESP8266, Bluetooth, and XBEE moduels, etc.. and all of that enclosed in a neat case. Evive was born. Evive specifications: MCU – Atmel ATmega2560 8-bit AVR MCU @ 16 MHz with 256KB flash, 4KB EEPROM, 8KB SRAM Storage – micro SD slot up to 32GB Display – 1.8″ TFT display; 160×128 resolution; 18-bit color User inputs – Tactile and slide switches, joysticks, and potentiometers Probes inputs – Voltage / Intensity sensing inputs USB – USB device port Expansion Headers […]
Raspberry Pi Zero Based Google’s Project Bloks Aims to Teach Programming to Young Children
Visual programming development tools such as Scratch or Blockly are now becoming more popular to introduce school children to programming, and Google Research is now working on bringing the software visual programming concept to physical blocks “programming” though Project Bloks targeting younger children who may not be able to write or read yet. It might also help older children grasping programming concepts faster than when programming by typing on a keyboard. Project Bloks is comprised of three main hardware components connected together: Pucks – Those are the buttons, dials, switches, and other inputs from the project. Pucks have no active electronics, and even a piece of paper with some conductive ink could be a Puck. Base Boards – They read a Puck’s instruction through a capacitive sensor, and forward a Puck’s command to the Brain Board. Each Base Board is also fitted with a haptic motor & LEDs, and can […]
