The 86Duino is a high performance and fully static 32-bit x86 processor board compatible with Windows OS, Linux and most popular 32-bit RTOS. It integrates PCIE bus, DDR3, ROM controller, xISA, I2C, SPI, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet, FIFO UART, USB2.0 and SD/SATA controller within a single package to form a system-on-a-chip (SOC).
Everyone knows them, some already have one: a robotic lawn mower! You can purchase them, sometimes they are ‘intelligent’, sometimes they are simply silly. Very often, they are missing an important piece: adding your own ideas to the robot’s ‘brain’. That’s the idea of this project (’Ardumower’): Making a new ‘brain’ freely available for every robot mower in the universe!
During the Maker Faire Rome, I was lucky to get an Intel Galileo. But when I had to use it, it was suddenly clear that it’s not as straightforward as Arduino. I had to resort to desperate measures and do something that really only a very restricted class of noble people do, I had to read the manual.
My house/office has a store window and I try to make use of it as much as possible. I had some projections etc. in there before, but now I wanted to make something interactive. We have a lot of loitering youth and many people passing by. To appeal to a wide audience, I thought it would be nice to make an old fashion arcade box like thing.
It’s now on the street for one day and people really seem to like it. Age or background doesn’t make a difference.
To make it a little bit more challenging, I thought it would be fun to try to run the hole thing on an Arduino without an external computer. Just to see how much power it actually has. And while I was at it, I decided to try to make everything myself. So I also made my own led screen, with his own “display driver” and display list, a 8-bit sound library, and of course the game itself.
I’m calling it MotionMote because it detects motion and because pretty much every type of wireless sensor or Moteino node name ends in “mote“. The possibilities for home security are endless, put this little guy in a corner near a door or on top of a cabinet somewhere and detect them intrudaz! Did I say there’s no wires? Read on for details and source code and case design.
The LightBlue Cortado connects your physical things to the digital world. Itʼs an Arduino that youʼll never plug in, and it works on all your favorite platforms including mobile (Mac, Windows, iOS, Android). It connects via Bluetooth Low Energy, an efficient protocol meant for supporting low-power sensors. If there ever was a building block for the Internet of Things, this is it.
It’s so easy to interact with Cortado, we think it will inspire an entirely new interaction flow. To illustrate this, the pre-ordered units will be turned on before they ship. If you download our app, you will get a BLE notification on your iPhone when your Cortado is nearby. Youʼll even be able to program it while it’s still in the box!
This video is about how to use the screen and play sounds on the Arduino Robot's speaker. David and Xun upload the DiscoBot example to show how to navigate through the different sounds using the keypad and the Slideshow example to load different images. Songs and images can be stored on a uSD card.
O.Duino is an Arduino compatible board based on ATmega328 ATMEL's mcu. This board features many peripherals usually externally connected on a breadboard or prototyping board such as sensors, SD card etc.
I bought most of the parts to built a self balancing bot many months ago. This time I didn’t use cheap Chinese stuff. I actually bought Pololu parts from a local shop. Pololu has a nice range of motors and motor controllers. I wanted to keep the bot small so I used the micro metal gear motors with 2 matching 60mm wheels. I did go for the most powerful version of the micro metal gear motors. To control the motors I got a DRV8833 break out board.
[ Analog x Digital ] Analog wooden blocks (1.5"x1.5"x3" each) as digital pixels. 64 wood pixels in 8x8 make a form. One pixel might make you bored but it gives you something interesting when pixels make a form together.
A while back I built a simple constant current electronic load using an aluminum HDD cooler case as the heatsink. While it was sufficient for a few amps’ load under low voltages, it could not handle load much higher than a few dozen watts at least not for a prolonged period of time. So this time around, I decided to build a much beefier electronic load so it could be used in more demanding situations.
One of the features a lot of commercial electronic loads has in common is the ability to sink constant power. Constant power would come in handy when measuring battery capacities (Wh) or testing power supplies for instance. To accommodate this, I decided to use an Arduino (ATmega328p) microcontroller.
TThe original Adafruit Motorshield kit is one of our most beloved kits!http://www.adafruit.com/products/1438 --which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:
Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.
This project is an Arduino-powered infrared touchscreen / coffee-table interface that I've been using to control various music and graphics applications on my computer. This is an old project that I've recently had time to go back and document/fix up; this project is a little more special to me than most because it was my first Arduino/electronics project, and while I was doing research for it I ended up on Instructables for the very first time. I've been using this controller primarily to drive music and graphics applications running in MaxMSP.
Gert van Loo, the Broadcom employee responsible for the RPi alpha build has now come up with the Gertduino. He also gave us the GertBoard GPIO Expansion board some time ago which provides general purpose I/Os, LEDs and motor driver capabilities for the Rpi. Gert’s latest creation, the Gertduino board, plugs onto the RPi and connects it to virtually any existing Arduino Shield. The board itself basically offers the same functionality as the Arduino-Uno but with some added features thrown in.
Alexander Carl is a Canadian engineer designing and building one of the world’s first diy solar thermal powered car in sunny La Paz in Mexico. He contacted us through Arduino Facebook page to show us his project developed using Arduino Mega to sun track the 24 x 6 foot curved mirror, to sense the temperature and pump hot oil and many other things.
I am glad I finally finished making a video for it, and it’s time to introduce SquareWear 2.0 — an open-source, wearable Arduino microcontroller board. At heart, SqureWear 2.0 is an Arduino running at 3.3V and 12MHz. It has built-in mini-USB port for uploading programs, charging lithium batteries, and creating a serial communication channel. It comes with a lot of useful built-in components, such as a color LED, a general-purpose push-button, a buzzer (yup, you can make it sing a tune), light sensor, temperature sensor, three MOSFETs (to drive high-current load). Even better, it has a built-in rechargeable lithium coin battery (you heard it right: rechargeable coin battery!), so you can power your project right away without requiring external power supply. Every time you plug in the mini-USB cable, it charges the coin battery automatically. Better still, if you want a beefier battery, you can plug in an external lithium battery through the on-board battery jack. The built-in lithium charger can charge external battery as well. Overall SquareWear 2.0 packs a lot of useful features on a 1.7″ x 1.7″ board. It’s great for wearable electronic projects as well as general-purpose microcontroller projects.
A reflow oven comes in handy when you work regularly with SMT circuits. I’ve had the T-962A reflow oven for about a year now. While it has worked reasonably well, recently it has started showing some signs of aging. First of all, the total reflow time is quite long, about 15-16 minutes. This is really slow. Worse even, occasionally the internal temperature sensor would have a hiccup and the boards would come out under-heated or over-heated. Also, I hate the built-in buzzer, which produces a very loud, high-pitched beep when reflow is completed. This is very annoying — since I keep the reflow oven outdoors, I didn’t want my neighbors to think the beep is my fire alarm. So it’s time to find an alternative / backup solution.
