tinyDino – smallest Arduino board

Jaanus has been working on a subminiature Arduino clone which be believes is THE smallest. Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – qnf28 (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in. His design provides […]

Build an LED display board that Tweets

Robert Diamond is with Alpha One Labs in Brooklyn. When they acquired a discarded LED sign sans control circuitry that they wanted to repurpose, they knew their work was cut out for them. He writes: After hooking it up and enabling it to display incoming tweets, a prototype was born. In this guide, I’ll walk […]

Arduino vitamin/pill reminder

Having to remember to take a vitamin or medication periodically can easily result in missed doses. If it’s a vitamin, probably no big deal. But if its a medical maintenance drug a missed dose can have serious consequences. Ryan Blace from ibuildthings informs us of his latest project, a vitamin/pill reminder. He designed this Arduino […]

Arduino TNC

Amateur radio operators use various digital data modes for radio communications. One such mode is known as packet radio, which transmits data in groups or “packets” of bytes. As described by the ARRL, “packet radio allows improved throughput and error control. The basic protocol for packet radio is AX.25. Transmission speeds typically range from 300 […]

Steampunk record player

The eccentric thinkers at asciimation have developed a phonograph using the Arduino. In the steampunk tradition, the turntable is steam powered and made from scrap parts. The speed is controlled by the Arduino using six magnets and a coil as a pickup. They use the PID controller library in controlling the servo based on the […]

Arduino goes open development

Arduino Labs is a new open development playground for the Arduino. Open development is when in-progress source code, design files, and documentation are available to anyone. It’s the norm in open source software, where design is almost always public and collaborative. Open hardware shops usually like to keep new stuff under wraps until it’s “ready” […]

Bluetooth Morse keyboard assists the disabled

In an effort to assist computer users with disabilities limiting their keyboard dexterity, the crew at Zunkworks developed this wireless Morse code based keyboard interface device. The user keys in the desired characters using the “dot” and “dash” buttons on the left of the board and the Arduino based device converts these Morse code characters […]

Arduino and open source go to sniper school

Antipasto Hardware posts this cool project demonstrating how to use an Arduino and a TouchShield to keep track of shot patterns while at the range. This is a quick video showing off the Arduino Liquidware TouchShield Slide, and Bjorn Entperprises camo case, all Open Source Hardware based, at the firing range with a Remington 700 […]

Tutorial: Using SD/micro SD cards with an Arduino

Our friends at Adafruit have posted this tutorial on using SD and Micro SD cards with Arduino. This is a great resource for beginners looking to expand their knowledge as well as advanced users who want to brush up on microcontroller interfacing skills. They use the latest version of the Adafruit SD Card library available […]

Rosserial library for Arduino released

Michael Ferguson and Adam Stambler have released the rosserial library for Arduino. This is a new library for connecting the Arduino platform to ROS, allowing an Arduino to directly publish and subscribe to ROS messages. There are also demos ranging from controlling servos to using an Arduino and rxplot as an oscilloscope to reading temperature […]

Easily measure inductance using Arduino

Moser from ReiBot has developed a simple project for using an Arduino along with an LM399 and several discrete components to measure inductance. He says: So you need to make or measure an inductor, but you don’t have an oscilloscope or signal generator? Measuring inductance with a handful of cheap common parts is certainly possible. […]

Pulse sensors for Arduino

Joel Murphy and Yury Gitman of pulsesensor.com are developing an Arduino compatible pulse sensor. “Pulse Sensor” is a well-designed plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. After a few months of testing […]

Video: Hardware hacking for software guys

As the time for Defcon 19 nears we got to looking over last years videos and found this intro to Arduino for software guys. Dave King’s presentation is one of the better tutorials for programmers who want to learn the basics of the Arduino. An introduction for newbies, a refresher for the rest of us. […]

OpenDuino hackerspace monitor

The Luxembourg based syn2cat hackerspace has a system in place to provide members with information on the open/closed status of the space online or via an Android app. They call it OpenDuino, and it is more than a web based status monitor. OpenDuino also operates as a security system, allowing members to open and secure […]

Visualizing TV dialog using closed caption data

nootropic writes:  Guys, I did some pretty cool stuff with visualization of the dialog spoken in TV broadcasts. I accomplished this by decoding the closed caption stream (data embedded in NTSC broadcasts) and displaying it with a Processing program. Check it out…! One of the coolest things you can do with the nootropic design Video […]
