Last century I spent weeks researching car computers. I wanted mp3s, videos and access to Notepad on the road. I wanted my car to respect and love me, just like KITT loved David. I wanted it to shout, “Right on tiger!” when I achieved an optimum MPG and to flash up encouraging messages like, “Hello Clive, might I say that you are driving very handsomely today” on a heads-up display.
Sadly it was never to happen. The reality was that you needed a PC the size of a coypu in the boot; an industrial 12/240v inverter; a 15″ CRT monitor strapped to your dash; and hawseholes in your bulkheads. And after a week of constant rebooting halfway through Captain Sensible’s Happy Talk, your hard drive failed because of the vibration and your battery discharged for good. (I gave up and bought a 32Mb Diamond Rio and a hi-tech cassette adapter instead.)
Back in the 21st century, Derek Knaggs at Flamelily I.T has made the thing of my dreams: a low cost, low maintenance, general purpose car computer. There are other Pi-based car computers about but we especially liked this one because it’s simple, cheap and it looks like a factory fit. Very smart.
A quick swap of SDs and Raspbmc meets all of your multimedia needs
The Raspberry Pi is stored in the centre console and all wires routed underneath. Audio is fed through the aux socket of the car’s radio so no additional hardware is needed for this. A wifi dongle provides internet connectivity on the move via a mobile phone hotspot.
Neatly tucked away in the console — note the wifi dongle for internet on the move.
Full details including a shopping list are on Derek’s blog. I’m off to make one.
Sometimes it’s necessary to modify existing technology. Sometimes it can be done for fun. Computers have a long history of being modified. However, as computers, namely laptops, have gotten more compact, it’s become increasingly harder to perform any sort of modifications or fixes on them without the help of professionals. And, as the price of such technology increases, so to does the fear of cracking one open to meddle with any of the parts inside. I am of the belief that we have a right to do whatever we choose with the products we buy as consumers. We should have the right, and the access, to the necessary information, to not only modify goods but also to fix them should something go wrong. In a world stricken with planned obsolescence and ever increasing technological advances, it may seem impossible at times to work on and modify the technology that makes up our everyday lives. But, with a little know-how and the right tools, anyone is capable of taking that power back into their own hands.
I recently had such a problem. I had purchased a used Macbook from Craigslist. It functioned perfectly for over a year, and then, one day, the WiFi started acting up. While traveling in Boston, I discovered that I could not connect to the wireless internet provided by the hotel in which we were staying. I tried every trick I could think of, but ultimately nothing worked. I came to the conclusion that my wireless card had malfunctioned and began looking around for a replacement. Once I returned home, the WiFi started working, but only in select locations. I noticed that if I was close to the wireless router (such as in my home), I could connect just fine, but if I was far away from it (such as in a hotel), it would just not connect. Thus, I came to the conclusion that it was not my wireless card but the internal WiFi antenna. This made sense. The laptop was used and probably had been opened and closed hundreds, if not thousands, of times, wearing out the cable antenna that runs from the card up around the LCD.
Luckily for me, I had modded the wireless antenna on a laptop before. Many years back, I had purchased an Asus EeePC online. It was meant to be a laptop specifically for my vehicle. Wardriving was a popular pastime amongst my classmates in college. I was never big on the idea, or savvy enough to attempt it, but I was still intrigued by the idea of getting free internet on the road. I found some EeePC mod tutorials online and set about adding an external antenna connection to my laptop. Once complete, I used an external antenna atop my car to “borrow” internet from McDonalds and Starbucks around the neighborhood. It worked great, but it wasn’t long before the smartphone in my pocket made my rig obsolete.
The Asus EeePC with an external antenna connection protruding out the side.
Using the knowledge I had gained while hacking the EeePC, I decided I would try this fix on my Macbook before buying a new wireless card. Again, using some awesome tutorials I found on ifixit.com, I was able to easily take apart the computer and begin my hack. Using my trusty Dremel, I very carefully chiseled out a slot for my external antenna connection. I then used one of SparkFun’s U.FL to RP-SMA connectors to replace one of the internal antenna connections. Finishing it up with some Sugru made for a sleek looking protrusion on my Mac.
As you can see, there was little room inside the laptop for the connector, so the only choice was to have it live on the outside of the laptop.
The modded Macbook. I had to form the Sugru just right so the power plug would fit in place
Once the Sugru had dried, I put everything back together to make sure the laptop still worked. Then, I attached one of our 2.4GHz duck antennas to the RP-SMA connector. I noticed an increased range in my WiFi right away. I took it to some other locations I had previously had trouble getting a connection, and, with my new mod, the laptop had no issues connecting whatsoever.
The final mod has been in place for several months now. I was worried about it sticking out too far and breaking off, but the Sugru has proven to be very resilient, even when my laptop gets shuttled around in my bag. As you can see, bringing some new life to older products just takes a little ingenuity, some searching, and the right tools.

The bombings at the Boston Marathon were a human tragedy, with the deaths, hundreds physically injured, thousands psychologically affected, and an entire metropolitan area disrupted. They also served to illustrate the duality of technology.
First off, we wanted to provide an update on the results of the SparkFun Donation Day. If you missed it, 10% of all SparkFun sales on this past Monday (5/20) were donated to the Electronics Frontier Foundation. We chose EFF because we think their values align closely with ours. In the words of EFF Activist Parker Higgins:
“At EFF, we like to see people learn about the technology they own, make improvements, and to spread that knowledge freely (and fight in Congress and the courts to make sure they can!). That’s a mission that SparkFun is totally aligned with, and we’re so glad to see that the hackers, makers, tinkerers, and other curious people in the SparkFun community recognize that and give us the support we need to keep defending digital rights.”
Once again, the members of the SparkFun community didn’t disappoint and we are proud to announce we will be cutting a check for $13,328.85. As you can see (by doing a touch of math), it was a huge sales day – one of the biggest we’ve ever seen. Thank you so much for participating and helping out the EFF!
You may or may not have known this, but for years, SparkFun has run a second company called BatchPCB. We created BatchPCB as a way of giving hobbyists, students and engineers an easy way to get small runs of custom PCBs fabricated for a reasonable price. Our idea was simple – users submitted their designs, which were “batched” together onto one panel. We ordered the entire panel, broke it up into the individual designs, and then sent you your board. It took the idea of “power in numbers” and applied it to PCB fabrication.
Patrick from BatchPCB showing off for the new “marketplace feature” which allowed users to sell their designs directly on the BatchPCB website.
Fast-forward to a few months back, and BatchPCB continued to be a successful enterprise. However, SparkFun itself has grown beyond what we really ever thought was possible. We had put a ton of time, energy and love into BatchPCB over the years, but we came to realize that it was playing second fiddle to SparkFun. It was a nice fiddle – and a useful, functional fiddle – but a second fiddle, nonetheless.
Hey! Those are BatchPCB boards! (Seriously, they are.)
So we started to brainstorm what to do. We realized BatchPCB was a valuable resource to many electronics enthusiasts, so closing up shop was never really an option. We realized that the only way BatchPCB could get the attention it deserved was to sell it to someone who could provide a bit more focus. So we began looking for suitable buyers.
It wasn’t long before we discovered OSH Park. We found that their ideals align closely with ours and they had the infrastructure and know-how to help BatchPCB thrive. So after a series of discussions, we came to an agreement, and BatchPCB ownership was officially transferred on May 1st, 2013.
So there you have it. We now recommend OSH Park for all your custom PCB fabrication needs. They do great, high-quality work – plus their boards are an awesome purple color. It is a bit bittersweet to see BatchPCB migrate to a new home, but we know her new owners will treat her well. Farewell, Batch – we barely knew thee.
In conjunction with the release of the new version of the Arduino IDE and the Arduino Robot, we’re also putting out a TCT LCD screen. The screen was developed in conjunction with Complubot and the library relies on the Adafruit GFX and ST7735 libraries.
The Arduino specific library, named TFT, extends the Adafruit libraries to support more Processing-like methods. You can write text, draw shapes, and show bitmap images on the screen in a way that should be familiar to users of Processing.
The screen works well with all types of Arduinos with a little bit of wiring, and fits perfectly in the Esplora and Robot sockets. In addition to all this other goodness, there’s a SD card slot on the back for storing pictures and other data.
Conservation, hackspaces and Raspberry Pis. And sharks. How could this not be the blog of the day? Gary Fletcher of ZSL sent us this report.
Marine Conservation Camera
ZSL have developed low cost cameras to monitor marine biodiversity in large marine protected areas (MPAs) using the $35 Raspberry Pi single board computers and standard webcams and running opensource Motion tracking software. ZSL reached out to UK hackspaces to help design the cameras and achieved unprecedented economy and features.
Why Raspberry Pi?
Traditionally it has been incredibly difficult to capture events underwater – all of the usual apparatus such as PIR/heat, infrared and ultrasonic sensors simply do not work underwater. The Raspberry Pi literally opened up a new door with its low power consumption and processing power. It allowed us to deploy a solution which really fits the bill and without it would have been very troublesome to achieve!
Each camera was deployed on an anchored buoy. Mounted directly onto the buoys were two solar panels for charging two deep cycle 90Ah lead-acid gel batteries, the aerial, and a waterproof box containing the communications system. This was then connected to a 50m SWA cat-5 cable running down to the pressure vessel containing the camera itself.
The cameras are designed to operate at depths between 20 and 50 meters. Rlab’s (Reading Hackspace) Ryan White suggested basing the design around a clear polycarbonate tube, with machined HDPE end caps secured by threaded rods and double o-rings. One end-cap had a threaded hole which SWA cat- 5 cable was run though, anchored to the inside and then potted. This cable runs the power and communications.
BuildBrighton’s Mike Poutney and Paul Strotten machined the endcaps on their lathe and offered some great technical advice which was very well received.
The outer pressure vessels easily survived a 100m pressure test in a hydrostatic chamber. It should go significantly deeper had the internal structure not failed at that point.
Rlab’s (Reading Hackspace) Barnaby Shearer designed the internal support structure. This was laser cut from 3mm acrylic. The designs were done in 3D in OpenSCAD to check all the components fitted together, then projected into 2d for laser cutting. The acrylic was glued with tensol.
The junction box was 3d printed and then sealed using potting compound and left to dry for some time also forming a mechanical join between the inside and the cable gland.
Attached to the buoy in a waterproof case was a Raspberry Pi to coordinate the communications. This had an Ethernet link to the Raspberry Pi in the pressure vessel. It also had a WiFi dongle running in access point mode to allow easy monitoring and reconfiguration form the research vessel. The Pi also has a serial connection to an Iridium satellite modem so it can stream pictures of the images captured.
The satellite image transfer software was specially developed by Cambridge Consultants and the equipment and satellite bandwidth for this trip was kindly sponsored by Iridium.
Attached to the bottom Pi was an Eve board to provide the Pi a RTC and a temperature sensor. Also attached was Ciseco’s Humble Pi hosting an AVR and a mosfet to to turn the Pi off at night (and critically back on each morning). This Pi wake was developed by Miles and Matt from Ciseco, who make an amazing range of Raspberry Pi and microelectronics and are well worth a look – http://www.ciseco.co.uk/
These boards were slightly modified to handle a HackHD camera via the AVR so we could capture high definition footage as well as stills.
The boards were assembled at Nottingham Hackspace.
The camera used is the Microsoft LifeCam Cinema HD, a cost effective camera conforming to the UVC specification. The only gotcha proved to be that it seems to only respond to a few ‘magic’ exposure settings (5,10,20,39,78,156,312,625,1250,2500,5000,10000,20000), and you have to wait 100ms and reset the brightness after any exposure change.
Rlab (Reading Hackspace), Gary Fletcher and Doug Snead provided a simple command line program to control the camera, and a slimmed down version of MJPEG-Streamer optimized for this camera and with some additional time stamping.
This stream then fed into Motion which starts saving the frames as JPEGs after it detects an event. The JPEGs are then rsynce’d up to the top Pi (backups are always a good thing). ImageMagick then thumbnails and montages the images for efficient sending over the (slow) satellite link.
The project did spur off onto some stereo vision development work with Doug Snead and Gary Fletcher but could not be completed in time for deployment. It was hoped that it would be possible to develop this solution as so it could automatically size the passing fish to add to our conservation data.

What did it Look Like
The deepest ever Pi?
At 50 meters deep – could this be the deepest Pi to date?
Where was it Deployed?
The system was tested at ZSL in London Zoo behind the scenes and then went onto to open Ocean tests in the largest marine protected area in the world, the Chagos Archipelago.

Well as you can see the results speak for itself, but there is still quite a lot of development work to do but once these sentient units are complete, it will offer a low-cost monitoring system that, when deployed as a network, will greatly expand ocean areas that can be observed.

The LayerOne security conference is fast approaching and [charliex] is doing his best to put the finishing touches on this year’s conference badge.
Around the perimeter of the badge is 48 LEDs driven by two LED drivers. This allows for some crazy hardware hacking to create anything from a TV-B-GONE to a bulbdial clock. There’s also a few extra switches and sensors that can be hacked to do some interesting things, but where this badge really shines is the addition of an OLED display, allowing it to transform into an XMEGA Xprotolab, a small oscilloscope, spectrum analyzer, and frequency generator. Yes, this badge can be hacked, but it’s also a tool for hacking.
There’s an impressive amount of work that went into this badge, a feat even more impressive given the fact that the LayerOne conference is this weekend and the PCBs for these badges won’t arrive until tomorrow. We’ll be the first to say we’re masters of procrastination, but [charliex] really cut it close here.
Recently, Eric Gradman, a prototyper, lifelong inventor, and friend of SparkFun, sent us an awesome new project. His company, Two Bit Circus, is running a Kickstarter to fund the creation of the STEAM Carnival, a modern traveling carnival with high tech games, robots, fire, and lasers to inspire young inventors in science, technology, engineering, art, and math.
Once we all calmed down, we asked Eric a few questions about the project and how it came about.
Can you tell us a little bit about yourself and your background in electronics and STEAM?
I’m the CTO and co-founder of Two Bit Circus. My background is in robotics and rapid prototyping; that makes me something of a jack-of-all-trades around here. Nowadays I call myself a professional inventor (well, and ringmaster). If that isn’t the best job title ever, I don’t know what is.
I’ve always had a strong passion for electronics. I write software and I do mechanical engineering, but I think electronics is what really brings a project alive.
I’ve been creating interactive art, crazy prototypes, and “stunts” for years. I came to discover that creations with strong element of fun excite people the most. They also excite me more to design!

What is Two Bit Circus all about? What are some other projects you guy have done besides the STEAM Carnival?
Video games are growing exponentially more elaborate and engaging, but out-of-home activities with friends haven’t changed in nearly a generation. Would you rather go bowling, or experience an immersive live-action story, complete with projected effects, lasers and mechatronics?
At Two Bit Circus we build unconventional out-of-home amusement and entertainment products. A recent project (called Virsix) is a permanent installation at an enormous, family-friendly hotel. A team travels together through a series of four rooms, engaging with virtual characters and solving challenges together. We’re showing people a fun time they can’t get anywhere else.
Both Virsix and the STEAM Carnival depend heavily on the fun games and inventions we build every day; things like the Gantry Crane Redemption robot – a gesture-controlled, six-foot-by-three-foot, two-and-a-half axis robot for grabbing toys. Or the party-table, a custom video game system played in the round by up to six people.

How did the idea for the STEAM Carnival get started?
We’ve spent years making making crazy, high-tech inventions and stunts. Some of them – like OK GO’s Rube Goldberg music video for “This Too Shall Pass” – really blew up online. It’s been viewed almost 40 million times. We got constant feedback from teachers and parents thanking us for having inspired their kids about STEAM in a way their schools had failed to do. It got us thinking – can we produce an event that generates that same excitement? Well, everyone loves a carnival, so it seemed like a natural way to tie together the many fun projects we were building, and inspire kids to pursue careers in science, technology, engineering, art, and math.
How will the carnival work?
The carnival is likely to take place in a fairground, with a big-top tent at its center. Like any event at a fairground, you’ll find some familiar things: contests, prizes, tasty food, and live entertainment. But there will also be robots, lasers, and high-tech games like nothing you’ve ever seen. We spend all day every day dreaming up crazy games and other ways to show you a good time. For the first time, we’ll have it all in one place.
The carnival is going to start in Los Angeles and San Francisco next spring, but we really want this event to reach as many people as possible. I love Boulder, and I would love to take the Carnival there soon!

What materials were used when building the various parts? Any SparkFun parts in there?
I’ve been a SparkFun customer since Nathan was shipping out of his apartment, and SparkFun parts play a huge role in what we do. You need look no further than our signature game: the rotating Buttonwall Twister. Each gear panel features 21 giant arcade buttons, a SX1509 breakout board, some Darlington transistors, and a Raspberry Pi, all wired together on boards we manufacture in-house in small quantities.
Our games generally incorporate some novel sensor or actuator, used in an unusual way. Often, those elements are integrated into an Arduino, Raspberry Pi, or Beaglebone. We also repurpose consumer electronics in unexpeced ways. I seem to find a way to stuff a Kinect camera or a Nintendo Wiimote into just about everything.

Tell us about the initiatives and reasons to include at-risk youth in particular, as well as the plans to showcase kids' projects in the carnival.
We really want to showcase kids' own work at the Carnival. We’re going to have creative competitions, a digital art gallery, a concert featuring musical robots, and a fashion show of wearable electronics. We’re designing kits for kids to use to to help them participate. We actually hope to get SparkFun involved in the kit-making process; SparkFun parts are a pretty important part of our toolbox.
We recognize that not every child who will want to participate will have access to funds to purchase a kit so we’ve built a few solutions into the process. It’s crucial we’re able to level the playing field for kids, and give lower-income or at-risk youth equal opportunity to participate. Who knows, one day a Nobel prize winner could say: “It all started with building this musical robot for the STEAM Carnival, which led to a curiousity about science and engineering…”
To help this we’ve done a couple things. First, you’ll notice a few Kickstarter rewards allow donators to sponsor a kit to be supplied to an at-risk youth. We’ll be allocating those to local schools in at-risk areas. Second, we plan on enabling kids to have their own crowdfunding page to raise money to purchase a kit. We think that fundraising when you’re a child teaches a lot of important lessons that create a strong foundation for being an entrepreneur and innovator – going door-to-door, telling your story with passion, rallying a community, etc.

Overall, how will the carnival inspire a new generation to experiment and get involved in the STEAM fields?
We really see two core elements at work here. First, it’s not enough to have kids engage with the games, we need to help them make the jump from saying, “This is cool,” to “I wonder how this works,” and create the avenue for them to find out. This is one reason we plan on explaining how various STEAM elements were used to create each game. We want them to have an inside look and “spark” their curiosity.
Second, and this is an equally crucial element, we need the adults in these kids' lives to be inspired as well. We need them to be excited and curious and to want to learn and play alongside the kids. Growing up, we had supportive parents who encouraged our passion to build games, and tinker with things, and experiment – all of which was instrumental to us pursuing the careers we have.
Awesome job Eric & Two Bit Circus! In fact, we loved the project so much that SparkFun has sponsored a visit from the STEAM Carnival at our headquarters! If you’re as into games and fire (and education too, yes) as we are, check out their Kickstarter campaign. Good luck guys!

A post from Mr Raspberry Jam himself, Alan O’Donohoe. This one promises to huge and fabulous, and the National STEM Centre is an outstanding venue. I am strangley drawn to joining the trans-Pennine convoy from Preston.
“You may have seen that we are holding a big Raspberry Jam in York on Saturday 8th June, 3 weeks today. Tickets are available here.
I’ve been working with the folks at the National STEM Centre there to help establish a presence in Yorkshire for Raspberry Jams. There are a lot of people in Yorkshire who have bought Raspberry Pi computers or who have not bought one but are interested in discovering just what you can do with them and this event is to give them a taste of the Raspberry Pi.
This event is going to be much larger than our regular Raspberry Jam events and we know that people are travelling from far across the UK to attend. I will be travelling in a convoy of cars from Preston bringing old friends and new friends on the journey across the Pennines. Road-trips like these add an enormous amount to the whole experience.
Our busy programme of talks, demonstrations, stalls and hands-on classes is now filling up. We are delighted to have Pete Lomas of the Raspberry Pi foundation speaking and leading a workshop, he is the gentleman who actually designed the Raspberry Pi. We also have Amy Mather the 14 year old who learnt how to program Conway’s Game of Life on the Raspberry Pi, her film on YouTube has attracted over 27000 views.
If you look at our programme , you will see that we have a wide range of classes from how to switch on a Raspberry Pi to building weather stations, interfacing, networking, robotics, game making for all the family and programming in Python. David Whale will be running a workshop on how you can set up an after school Raspberry Pi club.
‘import random’, the start of great game! A Raspberry Jam programming class.
We hope to attract a diverse range of people to attend this family friendly event:
Teachers - who want to know if the Raspberry Pi is something they can use to support the teaching of Computing
Families - who together want to develop and nurture an interest in technology and computing
Hobbyists - who want to meet other people with a desire to share what they have been doing with their Raspberry Pi
Anyone - who has an interest in the Raspberry Pi at any level.
If there is a local company around these parts that mirrors our culture, it’s Oskar Blues Brewery. They tend to throw their money and efforts into their flavor of interests/hobbies (bicycle culture/advocacy, food, entrepreneurship, etc.). It’s an awesome and inspiring business model. Plus, they make a great brew and helped us host our soldering competition.
One venture Oskar Blues does every so often is “Makin' a Difference Mondays” – where a portion of sales for a day go to a charity/non-profit. We really liked that model of giving back – so we’re doing something similar. Today is the first-ever SparkFun “Donation Day.”
The way it works is like this: Today (5/20/2013), 10% of all SparkFun sales will be donated to a non-profit chosen through a vote by SparkFun employees. The organization we’ve chosen to be the recipient of today’s funds is the Electronic Frontier Foundation.
Here’s to you, EFF.
EFF is one of the very few non-profit legal entities out there which actively fights for our rights as consumers, geeks and hackers. So if you’ve been holding off on a SparkFun purchase to wait for just the right moment, and you want to support an outstanding organization – today is the day!
Some weeks ago I read an article on the New York Times talking about Kickstarter. The author was exploring the logic of the platform and especially in which way backers shouldn’t really be considered like investors. They aren’t because their main aim is not looking for the project that will give them the greatest return on their money.
Kickstarter as a phenomenon is made much more comprehensible once you realize that it’s not following the logic of the free market; it’s following the logic of the gift […] People contribute to them because they’re friends who know the artist personally; they’re fans engaged in a highly personal if unidirectional relationship with the artist [creator]; or simply because they’re intrigued by the project and want some sense of participation in it.
Here we are then, highlighting two Arduino-based projects because we are intrigued by them and hope you like them too.
After successfully putting the Smart Citizen Kit in the hand of over 150 users around Barcelona in Spain, the team – organized by Fablab Barcelona and involving collaborations from all over the world – is ready for the next, and most crucial step and they need your help. The Smart Citizen Kit infact is an Open-Source Environmental Monitoring Platform consisting of arduino-compatible hardware, data visualization web API, and mobile app, empowering communities to collect data of what’s actually happening in their environment.
PROJECT ENDS: June 16, 2013
Check out what are their plans in the video!
Many hexapods can’t sense they’ve reached the edge of a surface without a lot of additional hardware expense and complexity and this kit solves the problem! BOT-LOGIC is an easy-to-assemble hexapod kit & controller that enables servos to also act as sensors to control the force applied as well as measuring force at set positions. Robots are thus enabled to sense surface edges and uneven servo load as well as measure and maintain gripper force.
