    FastCo Story on CuteCircuit #WearableWednesday


    Geek Gets Chic With CuteCircuit’s High-Tech Fashion @FastCo Design:

    The problem with wearable tech is that all too often it simply isn’t wearable. Some designs are so aggressively nerdy-looking that the fashion-conscious won’t even think about donning them.

    London-based company CuteCircuit is trying to change that. Designers Francesca Rosella and Ryan Genz marry high fashion and high tech on the runway, making clothes that are as breathtaking as they are sophisticated.

    CuteCircuit’s newest collection recently debuted in a sci-fi fantasy of a runway show at Mercedes Benz Fashion Week. It featured glittering garments equipped with LED lights and models who used a smartphone app to make their outfits change color, glow in the dark, and play video loops.

    From Jawbone to GoPro, Venture Money Flows Into Hardware #WearableWednesday

    From Jawbone to GoPro, Venture Money Flows Into Hardware @ WSJ.com.

    A hardware startup is still hard, but it is getting a little easier. The growing availability of 3-D printers and starter kits with easy-to-program circuit boards makes it simpler and cheaper to produce prototypes. Contract manufacturers stand ready to handle mass production and unravel supply-chain tangles. New fundraising techniques help entrepreneurs get started and test demand.

    The result: U.S. venture capitalists completed a record 31 fundraising deals for consumer-electronics makers last year, eclipsing the previous high of 29 in 1999, according to DJX VentureSource. They pumped $848 million into hardware startups, nearly twice the prior record of $442 million set in 2012.

    The flurry of deals included new funding for Jawbone, which makes wireless audio equipment and an activity-tracking wristband, set-top-box manufacturer Roku Inc. and camera startup Lytro Inc.

    “It’s definitely the dawn of a golden age of hardware,” said Scott Miller, chief executive of Cambridge, Mass.-based Dragon Innovation Inc., which advises hardware startups and helps them raise money.

    Buckle up Tron Style #WearableWednesday


    Being visible at night is always a concern, whether you are riding your bike or just walking your dog. This LED belt spotted on Design You Trust is designed to keep you seen. There are some pretty gnarly statistics concerning pedestrians killed by autos, to the tune of 275K per year. So, this Halo Belt 2.0 is on a mission to protect anyone on the road. Think of all the potential users, including cops, joggers, children, military, roadside workers, and cyclists. That’s a lot of potential users.

    Apparently the company got its original start in 2012 on Kickstarter. So, they know how this belt thing works. Their site tells the story.

    We have utilized the feedback of early supporters and Kickstarter backers to create our new Halo Belt. The Halo Belt 2.0 has been redesigned to be brighter and rechargeable. We have also integrated our custom designed LED fiber optic system and 3M reflective elastic onto the belt that can be adjusted to the desired size and length to accommodate most users.

    Usually when you think of protective gear, the first thing that comes to mind is those reflective vests. Apparently they don’t hold up to a Halo.

    Since reflective jackets are only visible when a light source is projected onto it, it would be impossible to spot someone in the dark. We have designed the Halo Belt 2.0 to have a combination of high quality 3M reflectives as well as our illuminating LED fiber optic technology. This helps the user stay visible when he or she may not be in direct headlight projection.

    Considering most drivers are looking at their phones, that means less reaction time. So, better to go with the glow and hope that you are seen a few seconds in advance. Speaking of glow, check out our kit to make your own LED Belt.

    This shirt will let you feel what players experience on the field #WearableWednesday

    Wearable Tech Insider posted this awesome video of a shirt that lets viewers experience the sensation of what players feel on the field.

    It’s the ultimate insider’s sport fan gear. Imagine wearing your favorite player’s jersey, but clothes being tricked out to receive sensations of what the player is feeling as he’s on the field.

    They’re trying it out in Australia. Foxtel and the agency CHE Proximity worked with three Australian Rules Football players – Scott Pendlebury, Luke Hodge and Trent Cotchin. The three donned sensors and “recorded” what it felt like to get tackled, to kick a ball, to score. During broadcasts, fans who wear shirts equipped with the proper technology — Bluetooth, haptic sensors — will be sent appropriate sensations in real time. See the tackle, feel the tackle.

    One presumes the sensations will be a little tamped down; having a couch potato experience an actual tackle might be a little … intense.

    3D Printers Can Only Make Trinkets — What About Kayaks?


    Wow. [Jim Smith] of Grass Roots Engineering has just put the finishing touches on his entirely 3D printed kayak. And it floats.

    The individual parts were printed on [Jim's] massive home-made 3D printer, which is loosely based off a RepRap — except that its maximum build volume is a whopping 403 x 403 x 322.7mm.

    The kayak itself is made of 28 printed sections, and to hold it all together, he has installed brass threaded thermoplastic inserts, which then allow the pieces to be bolted together. Silicone caulking is applied before assembly to ensure a watertight seal.

    It was originally based off of a Siskiwit Bay kayak by [Bryan Hansel] but [Jim] has heavily modified it to suit 3D printing. It was printed at a layer height of 0.65mm to reduce print time, which still ended up being over 1000 hours! He even optimized the design to improve performance based on his own height and weight.

    The hull is 6mm thick, with a custom rib structure to increase strength — you can also see the method of fastening the sections together in the following image:


    In total it weighs around 65lbs, with 58lbs of that being ABS plastic — it used 7lbs of screws and brass inserts — wow! Oh and since the whole thing was 3D printed, [Jim] also added some handy features like camera mounts on the bow and stern. Talk about a big project!

    Have you seen anything else this big printed on a hobby 3D printer? Our first thought is the Replica DB4 project by [Ivan Sentch] — He’s building an Aston Martin DB4 using a donor car… and a lot of 3D printed parts.

    Finger Commands with Ring #WearableWednesday


    You’ve always dreamed of waving your hand around like Minority Report and now you’ve got your chance, according to the International Business Times. This new ring, which recently got funded on Kickstarter, allows the user to use small finger gestures to command things like text messages, paying bills and even controlling appliances. Looks like fun, right? It’s called the obvious — Ring.

    If a you want to send a text message, just draw the shape of an envelope in the air. Want to take a photograph? Just draw the shape of a camera and Ring will take a picture with the camera on your phone. In order to actually type a message using Ring, you would have to spell out words by drawing them in the air with your finger, which could be useful if you just want to reply “OK” or “5mins” but could become troublesome for longer sentences.

    You are probably thinking the same thing we are, “what if you are a sloppy writer?” Luckily there is an app that has you covered. It allows you to alter the pattern to make it easier for Ring to understand you. Check out the video that shows the font and functionality (love the lamp dimming).

    Logbar Inc., the creators, have covered all bases, with Ring working on iOS and Android phones, tablets, PCs, Google Glass, and some smartwatches. They’ve also made it social media and smarthome device friendly. What’s really exciting is that it represents one of the smaller and smarter wearable tech products we’ve seen. It takes its cue from the natural human behavior of pointing, which means it will be easier to adopt.

    Although uses so far suggest the practical, it would be interesting to see an interactive art piece conducted by this ring. Perhaps we will witness a new way to spin tunes — in the air. Ring has made their app open source for developers, so you can join in on the fun. Not quite there yet, but attracted to devices that react to movement? You should check out our guide to Motion Sensors; it’s a good place to start.

    Scough is a stylish scarf that filters out germs and pollution #WearableWednesday


    CrunchWear has posted about this fun new scarf that will let you walk fearlessly through the dirty streets of your city.

    The cold weather may be abating somewhat but that doesn’t mean we aren’t in for any more chilly days, particularly in the early parts of spring(not to mention next winter, and the eternal winter after that which is our souls.) One of the best, and easiest, accessories for avoiding winter chill is the humble scarf…

    Introducing the Scough, a scarf that filters out pollution and germs with the best of them, all the while remaining as stylish as anything else in your wardrobe. The secret here is an activated carbon filter that also contains a slight layer of silver. The end result is maximization of germ and pollution fighting power. Staying healthy is always a good thing, particularly if a zombie apocalypse-inducing germ is floating around like on the TV.

    The Scough comes in a variety of hip styles. After all, it was designed in Brooklyn(slight sarcasm intended, even though I do live there.) You can head on over to their website and pick one up for around $39. Happy scarf hunting!

    Fluke, we love you but you're killing us.

    Today (March 20, 2014), Fluke reached out to us. Here is what they had to say. SparkFun has officially accepted their offer and will be donating the Fluke multimeters to several educational institutions and schools.

    Part of SparkFun’s business model is to find really cool items that every hacker and DIY electronics person needs. A digital multimeter is one of those “must-haves.” We started sourcing a really great high-quality $15 multimeter back in 2008. This price-point enables countless beginners to get their feet wet in electronics.

    Fast forward six years and many thousands of multimeters sold. On March 7th, we were notified by the Department of Homeland Security/US Customs and Border Protection that our latest shipment of 2,000 multimeters was being inspected:

    Fluke SparkFun Homeland Security Letter

    This is to advise you that the following articles have been excluded from entry into the United States pursuant to US International Trade Commission Exclusion Order 337-TA-588.

    Uh-oh. Ok. 337-TA-588 is formally titled: “Certain Digital Multimeters, and Products with Multimeter Functionality.” You can grab the large 20.7MB PDF here. This is 162 pages of companies (Velleman, Harbor Freight, Elenco, Electronic Express, and Jameco to name a few) that have been brought under scrutiny by the US International Trade Commission because these companies were selling:

    digital multimeters and products with multimeter functionality that have a contrasting color combination of a dark-colored body or face and a contrasting yellow border, frame, molding, overlay, holster or perimeter.

    What do our multimeters have to do with this? Turns out Fluke filed for a trademark in 2000 and received it in late 2003. Fluke’s trademark number is 2796480 (thanks larrys on ycombinator). The USPTO website doesn’t like hard links so here’s another site that has their trademark info. The multimeters we sell have a yellow-ish border (it’s more like macaroni and cheese really) so we may be violating Fluke’s trademark. From Fluke’s Trademark filing:

    Rough sketch of Fluke DMM

    Fluke Coporation’s rough sketch of a digital multimeter

    Indication of Colors claimed: Color is not claimed as a feature of the mark.

    Description of Mark: The mark consists of the colors dark gray and yellow as applied to the goods. The dotted outline of the goods is intended to show the position of the mark and is not a part of the mark.

    Wow. I feel for the US Customs and Border Protection agents who have to interpret this. I don’t fully understand it but it sounds like any measurement device with a yellow border is now under the domain of Fluke’s branding.

    SparkFun Digital Multimeter

    According to Pete: “They’re destroying the meters because they’re yellow? That’s silly.”

    Yellow is awfully broad: In my mind, multimeters have always been yellow. I’ve never had the opportunity to own a Fluke-branded DMM so I’m not sure where my brain picked up this association. I can respect trademarks and company branding and I respect Fluke’s reputation for high-quality multimeters. If Fluke wants to own a color I would expect the USPTO to require them to assign an exact color just like Tiffany’s did with Tiffany Blue. But allowing a company to trademark ‘yellow’ seems broad.

    Wicked burden on small business: Trademark law is heavily skewed towards large business. Small business does not have the resources to stay abreast of all trademarks for all the products they don’t carry. If you’re going to put the onus on the little guy to avoid infringing IP then you shouldn’t need an army of consultants or attorneys to find this information. We will lose $30,000 on this shipment. But the cost of the legal legwork and manpower to make sure we don’t violate a future color seems unreasonable and simply not feasible.

    No recourse: Our multimeters are actually kind of orange, not Fluke yellow. The document from the Department of Homeland Security is matter of fact. Where is the opportunity for recourse? What is the appeals process? Because of a $150 per day warehousing fee we are forced to decide quickly with limited legal guidance and mounting penalty costs.

    Decide between bad and worse: So we really only have two options, ship them back or have them destroyed. Having them destroyed costs $150 per hour with no indication of how much time it will take to destroy 2,000 units. Returning them has been ruled out by the manufacturer in China because the import taxes in China are so steep (yay free trade) that bringing them back into the country to have them modified would be more expensive than paying for the return shipping and taxes. Between bad and worse, we have to have them destroyed. Sorry Earth.

    A message to Fluke: You’re cool! We like Fluke. We didn’t know about your trademark on yellow framed multimeters and we agree to change our colors. Perhaps we can be granted a 60-day license? There’s probably not enough time (the DMMs will be destroyed in a few days) but perhaps there’s a chance. We’d be happy to donate them to the cause of your choice.

    Things you don't know you don't know

    Image credit: jangosteve.com

    So where does this leave us? The stuff you don’t know you don’t know hurts the most. We were out of stock before this seizure happened so, sorry folks, we’ll be out of stock for a bit longer. We’ll change the DMMs from yellow to red. We’ll eat the $30,000 financial loss and 2,000 multimeters will be destroyed somewhere in Los Angeles. We learned a little more about trademarks. If you’re a business, watch out for yellow multimeters. If you’re a user, enjoy the glory of the Fluke yellow.

    Prophet 600: A Classic Synthesizer Gets Processor Upgrade


    We love classic synthesizers here at Hackaday. So does [gligli], but he didn’t like the processor limitations of the Prophet 600. That’s why he’s given it a new brain in the form of a Teensy++. The Sequential Circuits Prophet 600 was a big deal when it was released back in 1982/1983. The 600 was the first commercially available synthesizer to include a MIDI interface. The original design of the 600 could be called a hybrid. A Zilog Z80 microprocessor controlled modular analog voice chips. The Z80 was a bit stressed in this configuration though, and a few limitations were evident. An 8 bit processor just wasn’t quite enough for software driven envelopes and a Low Frequency Oscillator (LFO) control. This was further exacerbated by the fact that everything was driven through a 14 bit DAC.

    [gligli] discovered most of the limitations in the 600 were due to the processor. By beefing up the processing power he could really unlock the potential within 600. Since he didn’t actually have a Prophet 600, he started with the schematic. [gligli] created a PC based emulator for the digital circuits, learning the whole system as he worked. With that phase complete, [gligli] bought a used Prophet and started hacking. The Teensy++ required a few hardware mods to fill the Z80′s shoes, including cutting off a pin and adding a few jumper wires. We really like the fact that no changes to the Prophet 600 itself are required. Pull out the Teensy++, drop in the Z80, and you’re ready to party like it’s 1982 again.

    The new processor interfaces directly with the Z80′s 8 bit bus. Since the AVR on the Teensy has built-in RAM and ROM, it simply ignores the ROM and RAM address spaces of the original system. Interfacing a fast micro with older parts like an 8253 timer and a 68B50 UART does have its pitfalls though. The system bus had to run slow enough to not violate timing requirements of the various peripheral chips. To handle this, [gligli] added a number of wait statements in his firmware. Once the system was working, [gligli] was free to start adding new features. He began by smoothing out the stepped envelope and filter generators, as well as adding new exponential modes. From there he added new keyboard polyphony modes as well as pitch and mod wheel changes. The full lineup of new features are listed in the instruction manual (PDF link). Since this is an open source project, adding a feature is as simple as cracking open your favorite editor and writing it up.

    [Thanks Kiss]

    Feel Football Games with this Shirt #WearableWednesday

    You’ve got your nom noms spread out on the coffee table ready for the big game. Now you slip on your special shirt, ready to feel every tackle, while safely being a couch potato. Sounds fun, right? According to Digital Trends, the Alert Shirt is going to make your sport fantasy come true.

    The Alert Shirt connects to your smartphone using Bluetooth, and is filled with tiny motors which attempt to replicate how a football player feels at key moments during a game. Think haptic feedback on a larger scale, and against your body rather than the tip of your finger.

    It has been created as a promotional tool for Fox Footy subscribers in Australia, provided they sign-up for 12-months of access to Rupert Murdoch’s dedicated Australian Rules Football channel. Known for being a tough, hard-hitting sport, the thought of being on the receiving end of any punishment handed out in an Aussie Rules match doesn’t sound particularly pleasant.

    Alert Shirt

    There have been DIY’ers making Arduino scarves and t-shirts that can create a vibration sensation for the wearer, but this technology is more sophisticated because it is using a lot more data. Think of it as creating several event possibilities for the wearer, rather than just one.

    It’s not some half-hearted attempt to make the wearer feel closer to the action either. Apparently, data regarding what happens in a match is already being collected. It’s then matched to new impact and sensory data collected during training sessions, sent to Fox’s dedicated app, and finally to the sensors in the shirt during a live game.

    The effects aren’t only felt when a player gets tackled, as the shirt also “flutters” to simulate a player’s nerves before an important kick, and amps up to replicate the elation after scoring. It’s all in real-time too. According to a spokesperson, the Alert Shirt is the closest we can get to feeling what a player feels, just by watching the game.

    So far this fan sport garment is only going to do you some good in Australia. So, either book your trip or start tackling construction of your own gear. Make your own touchdown hoodie using our FLORA microcontroller and a Vibrating Mini Motor Disc. Then you just have to figure out how you are going to get the touchdown info to your shirt — maybe with a WIFI or BlueTooth shield. Build it and your friends will come.

    Epilepsy aid uses wearable sensors to predict seizures and call for help #WearableWednesday


    dezeen has the story on this wearable sensor that could help save the lives of those living with epilepsy.

    The Dialog device, developed by American technology company Artefact, would use a wearable sensor and an iPhone app to help monitor patients’ vital signs and keep a log of conditions leading up to, during, and after a seizure.

    “There are currently three million epilepsy sufferers in America, and it is the third most common neurological disorder after Alzheimer’s and stroke,” said Matthew Jordan, the project leader…

    The Dialog would deal with the problem by creating a digital network that connects the person living with epilepsy to caregivers, doctors, and members of the public who have installed the Dialog app with data and instructions on how to give assistance.

    The user attaches a nodule to the skin, which can be done either using transparent adhesive paper or by wearing it in a bracket that looks like a watch.

    Using a series of sensors that monitors hydration, temperature, and heart rate, it gathers information on the wearer and stores the data on a smartphone.

    Additionally, the sensor would prompt the wearer to take medication and record mood through the sensor’s touchscreen, and logs information about local climate conditions that could increase the likelihood of a seizure.

    In the event of a fit, the wearer simply grasps the sensor, which alerts a caregiver and anyone within close proximity of the sufferer who has downloaded the app.

    “It helps possible first responders be notified that a patient who is nearby is having a sustained seizure, directs the bystander to the patient, gives instructions on how to help the patient through the emergency, and affords a direct line of communication to the family caregiver,” said Jordan.

    When the seizure ends, information about the length of the seizure, along with other contextual information, is displayed on the user’s smartphone to help reorient themselves.

    Homemade Ball Mill Tumbles Along Like a Champ

    [Mike] enjoys doing all kinds of things with glass. He likes to melt it and fuse it into new things, so it’s perfectly understandable that he wanted to make his own glass. Doing so requires finely ground chemicals, so [Mike] put together this awesome homemade ball mill.

    The design is wonderfully simple. The mill is powered by a robust 12VDC motor from a printer that he’s running from a variable power supply in order to fine tune the speed. [Mike] built a scrap wood platform and attached four casters for the drum to spin against. The drum is rotated by a round belt he had lying around from various other projects. [Mike] already had a couple of those blue containers, which formerly held abrasive grit for use in vibratory tumblers.

    [Mike] had some trouble with the drum walking off the casters so he attached scrap piece of aluminum to form an end stop. All he had to buy for this project were the 5/8″ steel balls and the casters. The mill can also be used as a rock tumbler, though the bottle isn’t quite water tight as-is. He does not recommend this type of setup for milling gunpowder or other explosives, and neither do we.

    Make the jump to see the mill in action and get the grand tour. If you need more tumbling power, use a dryer motor!

    We Asked For It — An Arduino Bowel Gauge


    Well, we asked for it, and [TV Miller] delivered this hilarious and surprisingly accurate bowel gauge.

    Between our recent Wiping Your Bum with an Arduino feature and how to Measure Poop for a Better Sanitation Service, we guess we should have seen this coming. And you know what? It’s pretty awesome.

    He’s using an Arduino Uno with a home-made resistance sensor to “hack our bowels”. After all, how can you have a proper diet without knowing exactly what is coming out of you? Two copper or aluminum strips make up the resistance sensor with a few known resistors, a capacitor and a potentiometer for adjustment. He’s even included an LCD display as well so you can see the volume of your excrement in real-time! Classy.

    To see it in action (don’t worry, not that kind of action) stick around for the following video:

    We particularly enjoy the use of our logo:

    HackADay “Skull and Wrenches” logo used with(out) permission by HackADay.com

    We’ll let it slide… this time. He’s also included the code, you know, if you’re serious about this kind of thing.

    NEW PRODUCT – 2.8 TFT LCD with Touchscreen Breakout Board w/MicroSD Socket

    1770 LRG

    NEW PRODUCT – 2.8 TFT LCD with Touchscreen Breakout Board w/MicroSD Socket : Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

    This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit and SPI. For 8-bit mode, you’ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog) or you can purchase and use our resistive touchscreen controller (not included) to use I2C or SPI

    1770 rainbow LRG

    We wrapped up this display into an easy-to-use breakout board, with SPI connections on one end and 8-bit on the other. Both are 3-5V compliant with high-speed level shifters so you can use with any microcontroller. If you’re going with SPI mode, you can also take advantage of the onboard MicroSD card socket to display images. (microSD card not included, but any will work)

    Of course, we wouldn’t just leave you with a datasheet and a “good luck!”. For 8-bit interface fans we’ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, we have a library as well, its separate from the 8-bit library since both versions are heavily optimized. We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.

    Follow our step by step guide for wiring, code and drawing. You’ll be running in 15 minutes

    Hackaday in Shanghai: Electronica and a Gathering


    Whether you live in Shanghai, are at Electronics China representing your company, or by dumb luck just happen to be in town this week you can meet some of the Hackaday crew and score yourself some sweet swag.

    Anyone in town on Thursday night will want to get a ticket to Hackaday: The Gathering. Right now it’s all sold out, but we hope anyone with a ticket who is unable to use it will cancel so that another may take your place. Free food, drink, t-shirts, stickers, and other swag await… no wonder the tickets are already gone!

    The Electronica China conference started Tuesday at Shanghai New International Expo Centre, but it runs through Wednesday and Thursday as well. We’re attending, but we don’t actually have a dedicated booth. Hackaday is piggybacking with EEFocus, the Chinese contingent of our parent company. Both [Matt] and [Alek] will be hanging around the EEFocus booth (#W3.3686) shucking out hackaday T-shirts if you ask for one. Before he left, [Matt] mentioned that he’s excited to attend lectures on connected medical devices, the Automotive and EV boards, as well as the embedded systems forum.

    Make Your Eyes Glow with LEDs

    glowing eyes

    Want to achieve wicked-looking, glowing eyes with a simple trick? Kamui Cosplay suggests wrapping LEDs around your head. I’d recommend pulling them farther apart than what you seen in the photo so the LEDs are more on your peripheral than right in front of your eyes. You could even achieve the same creepy effect if you pull the LEDs only to your temples. Kamui did state she wore the bright lights for about 30 minutes for a show without any issues. Here’s how she did it:

    Many cool fictional characters have glowing eyes. Did you know, that it’s super easy to build this in reality? Just connect two LEDs, cover a part of the wire with silicone and glue these silicone stripes with skin glue to your temple!

    It looks like an easier solution than wearing painful contacts, even if they can only be worn for a short time. You could even paint the inside edges of the LED to further block the light. However, if you’re at all worried about them hurting your eyes, skip them altogether.

    MRFF: 3D Bioprinting


    There were a few keynotes at this year’s Midwest RepRap festival, and somewhat surprisingly most of the talks weren’t given by the people responsible for designing your favorite printer. One of the most interesting talks was given by [Jordan Miller], [Andy Ta], and [Steve Kelly] about the use of RepRap and other 3D printing technologies in biotechnology and tissue engineering. Yep, in 50 years when you need a vital organ printed, this is where it’ll come from.

    [Jordan] got his start with tissue engineering and 3D printing with his work in printing three-dimensional sugar lattices that could be embedded in a culture medium and then dissolved. The holes left over from the sugar became the vasculature and capillaries that feed a cell culture. The astonishing success of his project and the maker culture prompted him and others to start the Advanced Manufacturing Research Institute to bring young makers into the scientific community. It’s a program hosted by Rice University and has seen an amazing amount of success in both research and getting makers into scientific pursuits.

    One of these young makers is [Andy Ta]. An economics major, [Andy] first heard of the maker and RepRap community a few years ago and bought a MakerBot Cupcake. This was a terrible printer, but it did get him involved in the community, hosting build workshops, and looking into 3D printing build around DLP-cured UV resin. At AMRI, [Andy] started looking at the properties of UV-cured resin, figuring out the right type of light, resin, and exposure to create a cured resin with the right properties for printing cell colonies. You can check out [Andy]‘s latest work on his webzone.

    [Steve Kelly] has also done some work at AMRI, but instead of the usual RepRap or DLP projector-based printers, he did work with shooting cell cultures out of an ink jet print head. His initial experiments involved simply refilling an ink jet cartridge with a bacterial colony and discovering the cells actually survived the process of being heated and shot out of a nozzle at high speed. Most ink jets printers don’t actually lay out different colors on a precise grid, making it unusable for growing cell cultures. [Steve] solved this problem with an inkjet controller shield attached to a RepRap. All of [Steve]‘s work is documented on his Github.

    It’s all awesome work, and the beginnings of both bioengineering based on 3D printers, and an amazing example of what amateur scientists and professional makers can do when they put their heads together. Video link below.
