Many moons ago, [Joe Grand] built an adapter that turns Atari 2600 joysticks to USB controllers. Now it’s open source.
Hackaday Overlord [Matt] is holding an SMT and BGA soldering workshop in San Francisco on October 4th. Teaching BGA soldering? Yes! He made a board where the BGA balls are connected to LEDs. Very, very clever.
Our ‘ol friend [Jeremey Cook] built a strandbeest out of MDF. It’s huge, heavy, about the size of a small car, and it doesn’t work. [Jeremy] has built beests before, but these were relatively small. The big MDF beest is having some problems with friction, and a tendency to shear along the joints. If anyone wants to fix this beest, give [Jeremy] a ring.
Everyone loves the Teensy, and [Paul] has released his latest design iteration. The Teensy 3.2 isn’t that much different from the Teensy 3.1; the bootloader has changed and now USB D+ and D- lines are broken out. Other than that, it’s just the latest iteration of the popular Teensy platform.
The DyIO is a pretty neat robotics controller, a semifinalist for the Hackaday Prize, and now a Kickstarter. The big win of the Kickstarter is an electronics board (with WiFi) that is able to control 24 servos for all your robotics needs.
[pighixxx] does illustrations of pinouts for popular electronics platforms. Everyone needs a hobby, I guess. He recently put together an illustration of the ESP8266. Neat stuff is hidden deep in this site.
You would not believe how much engineering goes into making snake oil. And then you need to do certifications!
[David] identified a problem, created a solution, got a patent, and is now manufacturing a product. The only problem is the name.
Once upon a time, the aspiring nerdling’s gift of choice was the Gilbert chemistry set. Its tiny vials of reagents, rack of test tubes, and instruction book promised endless intellectual stimulation and the possibility of stink bombs on demand. Now a new genetic engineering lab-in-a-box Kickstarter, with all the tools and materials needed to create your own transgenic organisms, may help the young biohacker’s dreams come true.
The Kickstarter has been wildly successful. The initial goal was $1200AUD was met in a day, and currently stands at almost $6200AUD. Despite that success, color me skeptical on this one. Having done way more than my fair share of gene splicing, there seem to be a few critical gaps in this kit. For example, the list of materials for the full kit includes BL21 competent E. coli as the host strain. Those cells are designed to become porous to extracellular DNA when treated with calcium chloride and provided with a heat shock of 42°C. At a minimum I’d think they’d include a thermometer so you can control the heat shock process. Plenty of other steps also need fairly precise incubations, like the digestion and ligation steps needed to get your gene into the host. And exactly what technique you’d be using to harvest DNA from the animal, plant or fungal cells is unclear; the fact that most of the techniques for doing so require special techniques leads me to believe there’s a lot less here than meets the eye.
To be fair, I’ve been off the lab bench for the better part of two decades, and the state of the art has no doubt advanced in that time. There could very well be techniques I’m not familiar with that make the various steps needed to transform a bacterial culture with foreign DNA trivial. It could also be the case that the techniques I used in the lab were optimized for yield and for precise data, while the GlowGene kit provides the materials to get a “good enough” result. I hope so, because a kit like this could really expand the horizons of hackerdom and start getting the biohacking movement going.
One more go at new enclosures for the Amiga 1200. Yes, it’s a Kickstarter campaign, and we mentioned
a similar the same campaign last month. The previous campaign received a little more than half of the desired funding in a 30-day campaign. The new campaign received half its funding in a week. The only difference? Now you can put a Raspberry Pi in a newly manufactured A1200 case. And they say Raspberry Pi consumerism isn’t a thing…
Cheap SLA printing service. [Ian] and Dangerous Prototypes have made a name for themselves with dirt cheap, acceptable quality PCBs. Now they’re going for custom prints on a resin machine. It’s $0.95 per gram (density is 1.3g/cc). That’s cheap.
[James Willis] built a floppy drive orchestra. There are 16 drives in this orchestra, all controlled by an FPGA. Here’s the writeup.
Here’s a video overview of a real, huge, rideable hexapod robot. ‘Wow’ is just about the only thing we got for this.
Western Digital introduced a hard drive made specifically for the Raspberry Pi. It’s a hard drive with a USB interface, and a USB cable that connects to the Pi, the drive, and a power adapter. In other news, externally powered USB hard drives exist. You can buy a 2TB drive for the price of the 1TB PiDrive. What was that thing about Raspi consumerism?
Next week is the Open Hardware Summit in Philadelphia. We’ll be there (or rather, I will). We’ll have a post on the OHS badge up on Monday. Would anyone like to go see the lady made out of soap? It’s right around the corner from the venue.
Since 2010, over one and a half billion dollars has been transferred from Kickstarter backers to project creators, and with Kickstarter’s 5% cut taken on each dollar collected, that means Kickstarter has had somewhere in the neighborhood of 75 to 80 million dollars in revenue in the last five years. That’s a success by any measure, and as with this huge amount of money, questions must be asked about the transparency of Kickstarter.
This is not a post about a Kickstarter project for an impossible project, a project that breaks the laws of physics, or one that is hyped beyond all reasonable expectations. This is a post about Kickstarter itself, and it’s been a long time coming. In the past, Kickstarter has shown at least some transparency by cancelling projects that are obvious rebrandings of white label goods – a direct violation of their rules. Kickstarter has even cancelled projects that violate the laws of physics, like this wireless charging Bluetooth tag. It’s a start, but Kickstarter has a much larger problem on its plate: the Staff Pick problem.

[Matt] created an animated gif of New Horizon’s Pluto flyby. The source images were taken from the the raw LORRI images, modified so the background star field could be seen, and assembled with OpenCV. Because Pluto and Charon orbit each other around a point above Pluto’s surface, simply putting Pluto in the center of each frame wouldn’t work. It’s the best visual explanation of this weird arrangement yet, all brought to you by the magic of OpenCV and Python.
On the subject of Kickstarter creators that don’t understand the conservation of energy, I present this.
We don’t know exactly what’s going on with this one, but here’s a swimming pool covered with RGB LEDs. It’s controlled by two Rainbowduinos, and looks like the coolest disco floor you’ve ever seen.
[Frank]’s 2011 Hundai Santa Fe wasn’t cool enough, so he added an F16 flight stick to his shift knob. The choice of joystick is paramount here: Saitek joysticks look too techy, Logitech ones are too expensive, and the Warthog H.O.T.A.S costs $400. Joysticks are extremely niche peripherals these days, it seems. He ended up strapping an old F16 joystick from the 90s on his shift knob, and it looks close enough to the real thing.
Two bodgers are stuffing the engine from a Toyota Celica into a 1980 Mini, and they’re trying to make it look stock. We’ve seen their project before, and now there’s a new episode. In this episode: the pedal box, the steering wheel, and figuring out how to make the car drive straight.
PunchThrough, creators of the LightBlue Bean, have just launch a Kickstarter for a new version called LightBlue Bean+. The tagline for the hardware is “A Bluetooth Arduino for the Mobile Age” which confirms that the hardware is targeted at a no-hassle, get it connected right now sort of application.
For those unfamiliar, the original LightBlue Bean is a single board offering meant to marry Bluetooth connectivity (think Cellphones with BTLE) to the capabilities of a microcontroller-based hardware interface. The Bean+ augments this hardware with a 300m+ range increase, an integrated LiPo (600mAh or more), and headers/connectors where there were only solder pads before.
On the software side of things the Bean+ has four firmware options that make it speak MIDI, ANCS, HID, or Peer-to-Peer, only not all at the same time. The good news is that these are ecosystem upgrades and will work for existing Bean hardware too. The entire thing comes with online-platform integration and easy to use Smartphone tools to guide you through connecting and making something useful.
The board includes a battery tending circuit that allows it to be charged via the USB port but can run over a year between recharges if you use it judiciously. There is a slider switch near the pin sockets marked “A3, A4, A5” which toggles between 3.3v and 5v so that no level shifters are needed for sensors and other hardware you might use with it. The white connectors seen near the bottom of this image are Grove connectors. These provide I2C and Analog support to that ecosystem of add-on boards.
All in all this is a pretty sweet upgrade. The MSRP will be $45 but early backers can get in around 10-25% less than that. The price doesn’t mean it’s a no-brainer to pick one up, but the header options make this much more versatile and reusable than the original Bean and we like the idea of a rechargeable battery of the coin cells used by Bean+’s predecessor. It is an each choice for drop-in no hassle connectivity when bottom line isn’t your top concern.
Original LightBlue Bean is available in the Hackaday Store.
Everybody needs an external USB drive at some time or another. If you’re looking for something with the nerd cred you so desperately need, build a 5 1/4″ half height external drive. That’s a mod to an old Quantum Bigfoot drive, and also serves as a pretty good teardown video for this piece of old tech.
The Woxun KG-UV2D and KG-UV3D are pretty good radios, but a lot of amateur radio operators have found these little handheld radios eventually wear out. The faulty part is always a 24C64 Flash chip, and [Shane] is here to show you the repair.
Last year there was a hackathon to build a breast pump that doesn’t suck in both the literal and figurative sense. The winner of the hackathon created a compression-based pump that is completely different from the traditional suction-based mechanism. Now they’re ready for clinical trials, and that means money. A lot of money. For that, they’re turning to Kickstarter.
What you really need is head mounted controls for Battlefield 4. According to [outgoingbot] it’s a hacked Dualshock 4 controller taped to a bike helmet. The helmet-mounted controller has a few leads going to another Dualshock 4 controller with analog sticks. This video starts off by showing the setup.
[Jan] built a modeling MIDI synth around a tiny 8-pin ARM microcontroller. Despite the low part count, it sounds pretty good. Now he’s turned his attention to the Arduino. This is a much harder programming problem, but it’s still possible to build a good synth with no DAC or PWM.
