    Join Us at USASEF in D.C.

    In just a few weeks, we’ll be heading east to attend the United States Science & Engineering Festival (a.k.a. USASEF). USASEF is the largest STEM education event in the country and we are very excited.

    SparkFun at USASEF

    This is a reminder that we are hosting a few events that are free to anyone attending the pre-USASEF educator workshop. We would love for you to join us!

    The first event is Drag and Drop Programming for Robotics, taking place on Thursday, April 24th from 9 a.m. - 12 p.m.. During this workshop we’ll be using ArduBlocks, which is very similar to Scratch, to explore the six most important concepts for beginning roboticists. What are the six most important concepts? Join us to find out!

    alt text

    The second event will be Arduino Basics on April 24th from 1 p.m. - 5 p.m.. We’ll discuss introductory Arduino concepts and show you how you can use Arduino in your classroom.

    Lastly, we are hosting a Robotics Hangout in partnership with Ten80 Education on Friday, April 25th, from 9 a.m. - 5 p.m.. This will be a more laid-back event where we can discuss robotics, do some hands-on electronics projects and talk shop.

    SparkFun at 2012 USASEF

    Finally on Saturday and Sunday (the 26th and 27th), we’ll be in the RobotFest section soldering away and doing occasional workshops. We’ll be set up next to our buddies from Parallax. Come by try your hand at some beginner soldering. We’ll also be putting on workshops about Pico and Scratch at 9:30 AM to 11:00 AM both Saturday and Sunday. On Saturday in the afternoon you can learn how to sew e-textiles with some of our e-textile specialists at 4:00 PM to 5:30 PM. Sunday from 4:00 PM to 5:30 PM we’ll be helping people learn how to reprogram their Simons.

    We hope you can join us at one (or all) of these events!

    “The he Raspberry Pi generation”

    Heartbleed Bug is making the news, but check out what they’re calling the next generation…

    “Someone with a moderate level of technical skills running their own scripts – the Raspberry Pi generation – would probably be able to launch attacks successfully and gain sensitive information.”

    Using SIMMs to Add Some Extra RAM on your Arduino UNO


    A Single In-line Memory Module (SIMM) is a type of memory module containing Random Access Memory (RAM) which was used in computers from the early 1980s to the late 1990s (think 386, 486, Macintoshs, Atari STE…). [Rafael] just made a little library that allows you to interface these modules to the Atmega328p-based Arduino UNO in order to gain some memory space. His work was actually based on the great Linux on the 8bit ATMEGA168 hack from [Dmitry Grinberg] but some tweaks were required to make it work with [Rapfael]‘s SIMM but also to port it to the Arduino platform. The 30-pin SIMM shown above is capable of storing up to (hold on to your chairs…) 16MB but due to limited amount of available IOs on the Atmega328p only 256KB can be used. Our guess it that an SPI / I2C IO extender could lift this limitation. A quick (shaky) video is embedded after the break.

    Adorable Rapunzel and Flynn Costumes

    rapunzel and flynn costumes

    Whenever I consider a Rapunzel costume from Tangled, I immediately get hung up on the hair. She has a lot of it and about the only way to wear it and make it look believable is in the giant braid we saw in the movie. RPF user aelynn000 came up with a lightweight way to fashion the braid, and I’m impressed by how she put it together. It looks like it’s right from Tangled! She used foam strips covered by beige semi-shiny nylon and hair. Here’s how she tackled it:

    It will be done, however, by making beige-blonde coloured sleeves for foam strips ( about 3-4 inches wide and about 1.75 inches thick ) and then attaching wefts around the widths in intervals. The ‘sleeves’ are just to cover any white that may show through the hair. I’d rather have a slightly thin layer of hair with a coloured base as opposed to a 7 lb wig ( which I’ve heard many girls’ are ). The foam is pretty much weightless and the one tube which I wrapped in hair ( the method that was scrapped ) remains pretty close to weightless so so far, so good!

    Create Your Own J.A.R.V.I.S. Using Jasper


    Tony Stark’s J.A.R.V.I.S. needs no introduction. With [Shubhro's] and [Charlie's] recent release of Jasper, an always on voice-controlled development platform for the Raspberry Pi, you too can start making your own J.A.R.V.I.S..

    Both [Shubhro] and [Charlie] are undergraduate students at Princeton University, and decided to make their voice-controlled project open-source (code is available on GitHub). Jasper is build on inexpensive off-the-shelf hardware, making it very simple to get started. All you really need is an internet connected Raspberry Pi with a microphone and speaker. Simply install Jasper, and get started using the built in functionality that allows you to interface with Spotify, Facebook, Gmail, knock knock jokes, and more. Be sure to check out the demo video after break!

    With the easy to use developer API, you can integrate Jasper into any of your existing Raspberry Pi projects with little effort. We could see Jasper integrated with wireless microphones and speakers to enable advanced voice control from anywhere in your home. What a great project! Thanks to both [Shubhro] and [Charlie] for making this open-source.

    Lap Stopwatch with Adafruit OLED #WearableWednesday


    gyroscope on Instructables writes:

    This instructable will show you how to build your own stopwatch to record multiple splits using an ATmega328 programmable microcontroller. When one presses the start button (or slaps the metal band in my watch), the screen displays the last lap for a second then continues the time on the next lap. It’s great for all you runners out there doing an interval workout.

    Teach kids how colors are made with the color machine

    color machine

    The Color Machine (La macchina dei colori, in Italian language) is a tool to teach children about the use and the operation of RGB color coding, which is used in all digital devices (TVs, smartphones, computers, etc.). It was created with Arduino Mega by an italian duo composed by Fabio Ghidini and Stefano Guerrini:

    Using 3 knobs you can increase the percentages of red, green and blue separately, and the LED strip at the top of the machine lights up consistently with the color mix choosen.

    The Color Machine has 4 different operating modes: “let’s create colors”, “guess the color”, “the names of the colors” and “demo”. Under the guidance of a teacher, children can play and learn at the same time to recreate colors with additive synthesis. This device is currently used in the educational workshops of Musil – Museum of Industry and Labour of Rodengo Saiano (Italy).


    This is the first propotype:

    Squeeze-Controlled Flashlight #WearableWednesday

    Jung Soo Park made this soft flashlight with FLORA!

    By grabbing the handle and squeezing, the light turns on and the brightness increases as the handle is squeezed harder. Not only it is interesting as an interactive function, but also it is a useful function as the users can control the brightness of the light in order to not wake the other person that might be in the same room, or prevent themselves from squinting their eyes at disturbingly bright LED in the dark room.

    Getting Solar Cells in T-Shirts #WearableWednesday



    Reduced battery size and flexible circuitry are always fave topics of discussion at any geek’s table. A recent post on Nanowerk introduces polymer solar cells that can be woven into fabric, thus transforming t-shirts into comfy energy harvesters. Notice the Nano in the pic (no pun intended).

    Reporting their results in the March 27, 2014 online edition of Advanced Energy Materials (“Weaving Efficient Polymer Solar Cell Wires into Flexible Power Textiles”), researchers in China have developed a novel efficient wire-shaped polymer solar cell by incorporating a thin layer of titania nanoparticles between the photoactive material and electrode.

    Sounds like a lot to take in, but their graphic makes it look approachable.


    The above image schematically shows the structure of the wire-shaped polymer solar cell (PSC) with a titanium (Ti) wire and an aligned multi-walled carbon nanotube (MWCNT) fiber as cathode and anode, respectively. In a typical fabrication, a Ti wire was modified by growing aligned titania nanotubes on the surface by electrochemical anodization, followed by coating of a layer of titania nanoparticles. Two polymer layers were then dip-coated onto the modified Ti wire. The resulting Ti wire was finally wound with an aligned MWCNT fiber to produce the wire-shaped polymer solar cell.

    This material represents many of the changes happening in the industry. The ability to move and endure repetitive movement is critical with wearables. The team did a lot of testing in this regard, and the PSC material handled well, even after 1000 bending cycles. This is good news for tech that really needs to learn how to play well with stretchable fabrics. It’s also clear that nanotechnology is moving swiftly into our clothing, whether it be fabric that is stain proof, bullet proof or color changing. Finally, energy harvesting is a move in a much needed direction, and there is a growing population of people that want to be off grid. This will help take us there, however, if you want some instant gratification, you could give our Solar Charging Handbag tutorial a try.
