Getting Started with ReSpeaker WiFi IoT Board’s Audio Capabilities, Voice Recognition and Synthesis

ReSpeaker is a development board combining an Atmel AVR MCU, a MediaTek MT7688 WiFi module running OpenWrt, a built-in microphone, an audio jack, and I/O headers to allow for voice control and output for IoT applications. That means you could make your own Amazon Echo like device with the board and add-ons, use it as a voice controlled home automation gateway and more. The board was launched on Kickstarter a few days ago, and already raised $100,000 from about 100 backers, but I’ve received an early sample, so I’ll provide some more information about the firmware, and shows how to use with some Python scripts leveraging Microsoft Bing Speech API. You’ll need a micro USB to USB cable to connect your to computer (Linux, Windows, Mac OS…), and a speaker to connect to the board. Linux (OpenWrt) boots in a few seconds, and once it’s done all RGB LED will […]

Learn the Basics of Humanoid Robots with InMoov Finger Starter Kit

In a not so distant future, most humans will live off their government provided basic income, relaxing and drinking their robot brewed, drone delivered beer or soda, opened and served by their humanoid robot maid. Well, maybe… In the meantime, it might be interesting to learn how to make humanoid robots such as InMoov, but since it’s quite complicated, it might be better to start small… with a single finger. That’s exactly what InMoov Finger Starter Kit offers you to do in order to understand the basics principles of the complete robot. The kit includes: 1x 3D printed base support in ABS 3D printed finger parts in ABS 1 meter braided 200 LB tendon 1x 5cm filament for peg/pin use to assemble finger joints 1x wheel horn adapter (Servo Pulley) 4x screws to fix the servo to the base support. You’ll also need to provide your own Arduino Uno (or […]

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 […]

4Duino-24 is an Arduino compatible 2.4″ Color IoT Display Module with Atmel MCU and ESP8266 Module

I played with ITEAD Studio NEXTION serial color displays for Arduino boards and the likes a few months ago, and while the hardware seems good and the company offer a large choice of 2.4″ to 7″ models at a very affordable price, I didn’t find the Windows software to create the user interface to be very user-friendly. 4D Systems, an Australian company specializing in “graphics solutions”, will soon launch a similar 2.4″ display, but integrated into an Arduino compatible board also featuring an ESP8266 module for WiFi connectivity. 4Duino-24 “LCD  IoT Display Module” specifications: MCU – Atmel ATmega32U4 micro-controller with 32KB flash, 2.5KB SRAM, 1KB EEPROM Storage – micro SD card slot (FAT16 support) for data and logging WiFi Module – ESP8266 based with 802.11 b/g/n connectivity, 1MB flash, support for Wi-Fi Direct (P2P), soft-AP Display – 2.4” LCD-TFT resistive touch display module with 240×320 resolution, 65K colors, and powered […]

Arduino Industrial 101 Board Powered by Atmel AVR and Atheros AR9331 WiSoC Targets Industrial IoT Applications

The “One Dollar Board” Project Aims to Teach Electronics in Developing Countries (Crowdfunding)

I’ve already tried a one dollar board based on STM8s in the past, but it required a separate STLink debugger, installing a toolchain, and a few other steps. The “One Dollar Board” project, born in Brazil, has different objectives, as it aims to provide an easy way for pupils around the world to getting started with electronics, by simply connecting it to the USB port of a computer or board capable of running the Arduino IDE, and following the instructions printed on the board. One Dollar Board specifications: MCU – 8-bit MCU (likely Atmel AVR) with 8 KB flash 6x GPIO (input and output ports) USB – 1x USB port for power and programming Misc – 2x LEDs, reset button Expansion – Spaces for Wifi ESP8266, Atmel 24C256 serial EEPROM (256 KB), and L293 Driver motor (unclear where though) Power Supply – 5V via USB Dimensions – Compatible with Arduino […]
