MicroView is a Tiny Arduino Compatible Board with an OLED Display (Crowdfunding)

Last year, we’ve been presented with many small Arduino compatible boards such as MicroDuino, RFDuino, BLEDuino, Spark Core, Olimexino-Nano and more… All these boards have been own strength and connectivity options, but if you want to see what going on in your board, you’d either need to connect it to your computer, or connect some LEDs or an external display. Geek Ammo’s MicroView fixes that by providing an Arduino compatible board nicely combined with a built-in OLED display. This allows you to display stats, weather, play games, create wearable projects (watch, necklace), and all sort of other projects that may require a small display. MicroView specifications: MCU – Atmel ATmega328P @ 16 MHz with 32KB flash, 2 KB SRAM, and 1KB EEPROM Display – 64×48 OLED Display Digital I/O – 12 (of which 3 provide PWM output) Analog Input – 6 Operating Voltage: 5V Input Voltage: 3.3VDC to 16VDC, no […]

Arduino based Open Source ECU for Diesel Engines

If you buy a diesel engine without ECU (Engine Control Unit), what would you do? If you’re a hacker like synkooppi, you might just decide to design your own ECU with an Arduino, open source the code, and provide some documentation on your site. Many people already control motors with Arduino boards, they just happen to be electric motor, and not diesel motor. The system works with diesel engines with Bosch VP37 pumps, and it has been used successfully since 2012. The ECU is based on an Arduino Mega board with a 8-bit AVR MCU @ 16MHz. The latest source code is available for download (2013-10-06), and can be uploaded to the board via the Arduino IDE. Configuration is done with text-based interface using serial connection over USB port. Hardware schematics have not been released yet. This open source ECU currently support the following features: Integrated control map editor Diagnostic […]

Yeelight Blue and Yeelight Sunflower Bluetooth Low Energy and Zigbee Smart Light Bulbs for iOS and Android

When it comes Smart light bulbs, which can be dimmed and made to change color, the most popular product must be Philips Hue, using the Zigbee protocol, which you can control via iOS and Android devices though a Zigbee gateway, and costs about $60 on Amazon. Alternative have started to show up such as iLumi Bulbs, with Bluetooth 4.0 Low Energy (BLE) technology, that you can control with recent iOS and Android 4.3+ device without the need for a gateway, but with a price starting at $89. If you’re looking for cheaper alternatives, you’d have to turn to Chinese companies such as Yeelight which provides both Bluetooth LE and Zigbee light bulbs, respectively called Yeelight Blue and Yeelight Sunflower. Yeelight Blue does not require a gateway, but you’ll need a smartphone or tablet that supports Bluetooth 4.0 Low Energy. Recent iOS 5.0+ devices should support it. If your Android device […]

DIY Farm & Garden Automation with Arduino and APDuino Project

You would like to start to grow your own vegetables but you don’t really have enough place and/or time to take care of your garden. No problem! Just go vertical and automate your garden with an Arduino Mega, an Ethernet shield, and lots sensors and valves. That’s basically what Rik Kretzinger, who grew up on a Christmas tree farm, and has a major in horticulture, has done at his home. This whole system use a farming technique called aquaponics, mixing aquaculture (raising fish in tanks) and hydroponics (cultivating plants in water), and except planting and harvest, is mostly automatized. The hard part is to set it up. The firmware is based on APduino “Internet-of-growing” open source project that runs on Arduino Mega to gather data from sensors (humidity, temperature, pH, light…) and control the valve. Rik’s system also upload data automatically to Xively cloud so that he can monitor his […]

The Open Source Robots Invasion Has Begun: BeagleMiP, uARM, and PiddyBot

In the last few days, I’ve come across three affordable open source robots either based on BeagleBone Black, or Arduino compatible boards, and I’m sure there are many other projects out there for people interested in getting started with robotics without breaking the bank. BeagleMiP Self-balancing Robot I’ve found out the first robots from a long armdevices.net video showing two Mobile Inverted Pendulum (MiP) robots, able to stand on two wheels, designed by the Coordinated Robotics Lab of The University of California, San Diego: BeagleMiP educational robotics development kit from Strawson Design. The kit features the BeagleBone Black board with Texas Instruments Sitara ARM Cortex A8 processor and Novus Robotics Cape, an add-on board that provides 9-axis IMU (Accelerometer, Gyro, Magnetometer), 6 PWM connectors to power servos or brushless ESCs, 2 user-accessible buttons and 2 LEDs, a cell balancer & overvoltage protector, H-bridges to drive 6 DC Motors, and connectors […]
