Edison-Scope, is an Intel Edison controlled 200 Msa/S mixed signal oscilloscope. It provides an Operating System agnostic method to control the MSO-28 oscilloscope. By leveraging the web browser on the modern smart devices, one can control USB based hardware traditionally requires a desktop OS. Conceptually this project is very similar to the PiMSO project, but the similarity exist only on the client side. The server side was rewritten using Node.js. Node.js provided a more device independent solution to the server side of the WebMSO project.
I can't remember when I first decided I wanted to shoot a timelapse on a slider, probably, I suppose when I first saw a timescape video several years ago. In March last year I bought a Konova K2 800mm slider from Amazon. Now I need to motorise it!
KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM) all keystrokes from any Microsoft wireless keyboard in the vicinity.
The FTDI FT232 chip is found in thousands of electronic baubles, from Arduinos to test equipment, and more than a few bits of consumer electronics. It’s a simple chip, converting USB to a serial port, but very useful and probably one of the most cloned pieces of silicon on Earth. Thanks to a recent Windows update, all those fake FTDI chips are at risk of being bricked. This isn’t a case where fake FTDI chips won’t work if plugged into a machine running the newest FTDI driver; the latest driver bricks the fake chips, rendering them inoperable with any computer.
In a presentation at the Maker Faire held in Rome this weekend Arduino co-founder Massimo Banzi gave a preview of the soon to be released Gemma wearable Arduino board. The 27 mm diameter board contains an ATtiny85 processor programmable from the Arduino IDE via Gemma’s micro USB connector. The design is a collaborative effort together with Adafruit Industries who also worked on the Arduino Micro.
This article is a about a fully functional water level controller using Arduino. The circuit displays the level of water in the tank and switches the motor ON when the water level goes below a predetermined level. The circuit automatically switches the motor OFF when the tank is full. The water level and other important data are displayed on a 16×2 LCD display. The circuit also monitors the level of water in the sump tank (source tank). If the level in side the sump tank is low, the motor will not be switched ON and this protects the motor from dry running. A beep sound is generated when the level in the sump tank is low or if there is any fault with the sensors.
As open-source hardware users and makers, we love playing with new chips, boards and tools. And there is one chip which is quite popular these days: the CC3000 WiFi chip from TI. This chip comes with many promises: cheap (around $10), easy to use, low-power … It was featured in many articles around the web, but somehow it was quite hard to use with Arduino as there was no breakout board or library available.
In this Instructable I'll show you how to make a electronic dashboard for a bicycle. We'll be using an Arduino and a few off-the-shelf parts to create a system with light control and an LED speedometer.
This is a very low cost and basic from of home automation allowing you to turn on and off lights and other devices using your computer or mobile phone.
The main idea of this platform is to read NFC tags while keeping its power consumption low. The microcontroller is communicating with the NFC transceiver so you can use the platform as a standalone device or computer peripheral.
One way of debugging microcontroller-based projects is to send messages out the UART serial port. Then, a UART-to-USB interface can feed the messages into your PC for display. But I wanted a small, portable device for viewing serial data without a PC, and I wanted it to use my cell phone or tablet for its display.
Featuring 3 OLED screens on a flexible circuit board, this minimalist electronic wearable is stunningly bright, likes to be touched and features a rechargeable 10 hour battery. Apologies about the hairy arms (and the dubstep)!
I’m starting to source parts for my nixie tube experiments. I’m in the very early stages of prototyping a nixie clock. My Breakout Boards were a bust, but that’s not stopping me from pushing on with the nixie-tinkering.
I recently started brewing beer at home with a group of friends and one of the things that quickly came to light, is that maintaining a steady fermention temperature can be the key to a good brew. We have a stick on thermometer on our fermenter buckets which we can use for reading the temperature of the beer, locally, but I was wondering if there was a system I could hook up, so that all of us could check in on the beer via the web. Lo and behold, there are a few systems available for monitoring/controlling the temperature of a batch of homebrew beer as it ferments. But most of them require expensive equipment and the ones that don’t are still based on theArduino-sensor and Raspberry Pi-gateway model, which will set you back the bones of €80, if you make it yourself. As well as that, the webserver for the BrewPi system (most popular as far as I could see) runs on the Raspberry Pi in your home network. This means you have to configure port forwarding and something like dyndns to access it from outside the house, making the system configuration a bit of a chore.
Arduino's control small motors very easily; in fact, I've done a number of videos covering How to Control a Servo with Arduino, How to Control a Stepper with Arduino, and How to Accurate Control Steppers.
But another great thing about Arduino's is they make it very easy to control large motors - like the brushed DC gearmotors in this video buy using a motor controller.
There are a thousand of radio stations are broadcasting music/reviews/interviews over the internet. To listen these radio stations you will need a personal computer or tablet or smartphone or a stand alone web radio player.
The circuit I have designed is an inexpensive web radio player with high quality stereo sound.
At the Maker Faire this year I got lots of questions about soil moisture sensors, which I knew little about. So I started seriously researching the subject. I found a few different soil sensors, learned about their principles, and also learned about how to make my own. In this blog post, I will talk about a cheap wireless soil moisture sensor I found on Amazon.com for about $10, and how to use an Arduino or Raspberry Pi to decode the signal from the sensor, so you can use it directly in your own garden projects.
