Thursday, March 27, 2014 - 06:01Building a Network Controllable RGB LED Lamp from an Old Scanner
Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network controllable RGB lamp.
The overall result is an amazing color changing lamp that works perfectly. All that is left to do is create a case for it, or integrate it into an existing lamp. This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.

Thursday, March 27, 2014 - 06:00Netflix Picks Up Award-Winning SXSW Documentary ‘Print the Legend’ #3DThursday #3DPrinting
There have been a number of folks asking how they can see the startup desktop 3D printing documentary Print the Legend since it debuted at SXSW earlier this month. Here’s your answer: coming to the (small) screen near you!
Netflix has acquired the rights to documentary Print the Legend after its award-winning debut at SXSW.
The film, which chronicles the rapid rise of 3D printing, will premiere exclusively on Netflix later this year and will be available to stream everywhere that Netflix is available.
Legend, directed by Luis Lopez and Clay Tweel, follows MakerBot Industries and Formlabs, two 3D printing startups as they compete with established industrial players Stratasys and 3D Systems.
The film was produced by Steven Klein (Make Believe). The project was developed, produced and financed by Chad Troutwine (Freakonomics) and Audax Films. It took home the special jury prize for editing and storytelling in the documentary feature competition at the SXSW Film Awards earlier this month in Austin, Texas.
“It’s so rare for a film to capture history in the making, and Luis Lopez and Clay Tweel have done just that in their skillful presentation of the elation and betrayals experienced by young entrepreneurs, detailing the groundbreaking technology of 3D printing,” said Lisa Nishimura, Netflix vp original documentary and comedy. “This is a compelling glimpse into a game changing technology as it nears an inflection point going from the fantasy world of a few obsessed visionaries to a must-have technology that may enter every home.”
…Lopez, Tweel and Klein said in a joint statement: “To premiere in front of the most tech savvy and entrepreneurial festival crowd in the world and partner with the Netflix documentary team — who work brilliantly at the cutting edge of distribution — is truly a dream come true.”

Thursday, March 27, 2014 - 03:01Electric Scooter MK 1 — Tundra Upgrade!
After discovering his all-terrain snow scooter was terrible on ice — [Dane] decided he needed to do some upgrades.
In case you don’t remember, we first shared [Dane's] project back in December, where he zipped around city streets covered in snow. The scooter used a big knobby tire and a front ski to slide around on. To make it suitable for ice, he had to redesign it a bit to handle slippery surfaces; he needed to give it skates.
He had originally hoped to find figure skates at a thrift store (where he originally found the classic scooter), but had no luck — so he made his own. Some 1/2″ x 1/4″ steel bar later, a bit of welding, and he had a rather rugged front skate to work with!
After he was content with his upgraded front-end, he started adding studs to the back tire. He’s using plain old 3/8″ self tapping screws, and a whole lot of epoxy to make sure they stay in.
So does it work? Oh yeah.

Thursday, March 27, 2014 - 00:00Piezos For Haptic Feedback
The most common way to put some sort of haptic feedback in an interface hasn’t changed much since the plug-in rumble pack for the Nintendo 64 controller – just put a pager motor in there and set it spinning when the user needs to feel something. This method takes a relatively long time to spin up, and even the very cool Steam controller with voice coiled directional pads can’t ‘stick’, or stay high or low to notify the user of something.
[Tim]‘s day job is working with very fancy piezoelectric actuators, and when an opportunity came up to visit the Haptics symposium, he jumped at the chance to turn these actuators into some sort of interface. He ended up creating two devices: a two-piezo cellphone-sized device, and a mouse with a left click button that raises and lowers in response to the color of the mousepad.
The cellphone device contains two piezo actuators with a 10 gram weight epoxied on. A small microcontroller and piezo driver give this pseudo phone the smoothest vibrations functions you can imagine. The much more innovative color-sensing mouse has a single actuator glued to the left button, and a photosensor in the base. When the mouse rolls over a dark square on a piece of paper, the button raises. Rolling over a lighter area, the button lowers. It’s all very, very cool tech and something we’ll probably see from Apple, Microsoft, or Sony in a few years.
Videos of both devices below.

Wednesday, March 26, 2014 - 22:00Glowing Oogie Boogie Costume
Oogie Boogie is one of the scariest Disney villains as far as I’m concerned. He’s cruel and manipulative, but he does have a cool costume. Instructables user kristylynn84 fashioned the entire costume from burlap and because the costume is loose and lumpy, it meant she could take some liberties (she didn’t use a pattern). She took the extra awesome step of making Oogie glow in the dark. Here’s how she achieved that with glowing spray paint:
We used about 6 cans. You may want to buy 7 or 8, just to be safe, and return the last one if you don’t use it. But remember, the suit will need numerous coats, and so will the mask.
I took him outside and made him do some slow spins as I painted him up. It’s transparent, so you can’t see what you’ve done until you hold a black light to it, once it’s dried it will activate. Yes, the paint went through and I ended up painting my husband LOL, it made a cool effect. (The can says to not get it on your skin. But he lived.)
I would say….10-12 coats of spray paint and between those, you need to go over it with a hand-held black light to see where you’ve missed any spots.

Wednesday, March 26, 2014 - 21:07NEW PRODUCTS – 2.8 TFT Display with Resistive Touchscreen and 50-pin 0.5mm pitch top-contact FPC SMT Connector
NEW PRODUCT – 2.8 TFT Display with Resistive Touchscreen: This is a screen for advanced hackers who like the look of the TFT screen we’ve put into the PiTFT, TFT shield v2 and 2.8″ TFT breakout. This display has 320×240 pixels and is driven with the ILI9341 chipset. This is just the display module! No PCB is included! You can talk to this chip with SPI (4 or 3 wire), 8 bit parallel, or 16 bit parallel. It also can be put into “dot clock mode” for raw TTL signal in but we have never done this ourselves so there’s no example code for that.
We’re selling this module bare for those who want to integrate it into their own project. If this is your first time working with this TFT we suggest our breakout board which makes it easy to use SPI or 8-bit interfacing and also has mounting holes, level shifting, etc.. Otherwise you can pick up one of our 50-pin FPC breakouts and an 50-pin FPC connector and solder it up by hand. For the TFT command set, the data sheet is very complete, but we also have some Arduino code you can refer to here to get started.
A 50 pin, 0.5mm pitch, top-contact FPC connector is required to connect to this screen. We show one in the photos but it is not included! You cannot solder this connector directly to a PCB – a matching connector is required, you can pick one up here.
The resistive touch screen is a classic ‘analog’ touch screen which requires either a micro controller with analog inputs OR the use of a touch screen controller such as this one
NEW PRODUCT – 50-pin 0.5mm pitch top-contact FPC SMT Connector: This 50-pin FPC SMT top-contact connector fits perfectly with our 2.8″ TFT display with resistive touch screen. It is fine pitch so it is not so easy to solder! This is for expert SMT solderers.
Wednesday, March 26, 2014 - 21:00WS2812b Ambilight Clone For The Raspi
For how often the Raspberry Pi is used as a media server, and how easy it is to connect a bunch of LEDs to the GPIO pins on the Pi, we’re surprised we haven’t seen something like Hyperion before. It uses the extremely common WS2812b individually controllable RGB LEDs to surround the wall behind your TV with the colors on the edges of the screen.
One of the big features of Hyperion is the huge number of LEDs it’s able to control; a 50 LED strip only eats up about 1.5% of the Pi’s CPU. It does this with a “Mini UART” implemented on the Pi running at 2MHz.
There’s only one additional component needed to run a gigantic strip of RGB LEDs with a Pi – an inverter of some sort made with an HCT-series logic chip. After that, you’ll only need to connect the power and enjoy a blinding display behind your TV or monitor.
Thanks [emuboy] for sending this one in.

Wednesday, March 26, 2014 - 18:013D Printering: Custom RC Camera Mount Takes To The Sky
3D Printers are only good for printing trinkets and doodads, right? Not really. Although, I do print the occasional useless object, most of my prints are used for projects I’m working on or to meet a need that I have. These needs are the project’s design requirements and I’d like to share the process and techniques I use when creating a functional 3D object.
My pal [Toshi] has RC Airplanes and flies often. I have an Action Camera that I never use. Why not combine the two and have some fun? The only thing standing in our way was a method to mount the camera to the airplane. 3D printing makes it easy. If you have a popular vehicle or application, there may be something already available on a 3D model repository like Thingiverse. Our situation was fairly unique I decided to design and print my own mount.
Let’s start with the camera placement. Looking at the plane, there are two pretty obvious spots that would be good places to mount the camera; on the wing strut or the cross-bar between the pontoons. Certainly mounting the camera to the rectangular pontoon cross-bar would have been far easier than on the angled airfoil-shaped wing strut, but after giving it some thought, mounting on the strut would give a better view of the aircraft. I wanted part of the plane in the field of view.
Now we have an idea of where this thing is going to mount we have to take some measurements and make some notes. As you can see below my notes are super crude (and may have some extra doodles on there) but have the necessary information I need to design the camera mount. If you look hard you can even see I have a couple of brainstormed mount ideas, including a hinged design I determined would be unnecessarily complicated.
The wing strut is soft foam-filled plastic and is in the shape of a teardrop. To prevent damage to the strut when the camera is mounted, the shape of the mating portion of the clamp should be similar in shape. To do this, I just measured the length of the strut profile and both the thickness of the leading and trailing edges. These dimensions were used when creating the profile of the cutout in the clamp. Notice, I also added some chamfers at the leading and trailing sides of the cutout to prevent any potential pinching.
Keep It Simple, Stupid. Sometimes low-tech is the best way to go. The wing strut is at some angle, an angle I don’t know. I want the camera to be square to the ground, not angled like the strut. I used a method similar to a storey pole to record the struts angle and emulate it in my modelling software. With the plane on the floor a piece of paper was held with one edge also square to the floor. The angle of the strut was traced on the paper. At this point it is possible to measure the angle with a protractor but I just held it up to my computer screen and adjusted the angle of the mount until it matched my trace. Low-tech but effective.
It is pretty standard for cameras to have a 1/4″-20 female thread on the bottom for mounting to a stand. My camera was no different. The main mount is going to have a through-hole in it for the attachment screw to pass. Having a 1/4″ hole and a 1/4″ screw is going to cause some assembly difficulty, specifically the screw not easily going through the hole, able to turn freely or causing misalignment. There are industry standards for this exact situation, Google “clearances hole sizes” to find out what is appropriate for your screw size, there are a lot of charts available out there. The projects I work on require me to reference this type of information quite often so I downloaded a great app called ‘Nuts & Bolts‘. Notice on the bottom right of the screen it shows the clearance hole sizes. I’ll be using the free fitting recommendation, 0.2660 inch diameter.
I could have just had a hole in the main camera mount and screwed a bolt in to secure it but a design requirement was that no tools would be required for installation or removal. A 3D printed knob would do just fine. I had some 1 inch long 1/4″-20 bolts kicking around so that is what I decided to use. Since the bolt was so long, it would bottom out in the camera before it secured the camera to the mount. That extra length will have to be compensated for when designing the knob.
The depth of the female threaded hole on the bottom of the camera measured to be 0.200 inches. Since the intent is to NOT bottom out the screw before the camera was secure I backed off this measurement to 0.150 inches for use in the calculation:
BoltLength - ExposedThread - MountThickness = KnobThickness 1.0 - 0.150 - 0.300 = 0.550 inches
0.550 inches is how long the spacer portion of the knob will be.
There are two knobs and 3mm x 25mm screws that are used to secure the camera mount to the strut. I made knobs for the screws the same way I did for the main camera screw. The main difference is that these screws didn’t have a hex head to transmit torque and prevent the knobs from spinning on the screws. The holes in the knobs were made to have no clearance at 3mm in diameter and the screws were glued into the knobs for a permanent installation.
These 3mm screws engage captive nuts in the main clamp body. I used ‘Nuts & Bolts’ again to find out both the clearance hole size for the 3mm screws and the hex size of the 3mm nuts. The main clamp body has hexagonal recesses a little larger than the nuts, the nuts of which are glued in place.
Overall, I’m extremely happy with the final result. Installation to the aircraft takes only a few moments and is very secure. The mount location turned out to be in the perfect spot showing just a touch of the engine cowl. And the best part is it didn’t drop the camera! Check out the video of the maiden joy-ride below.
