    Sci-Fi Contest Prize Aquisition Issues — Oh Noes!

    sci-fi-contest-prize-woes

    We spent quite a bit of time picking out prizes for the Sci-Fi contest. But wouldn’t you know it, literally the day after announcing the contest we cued up The Amp Hour and heard about a worldwide stock shortage (34:00) of BeagleBone Black boards. About a week later Adafruit ran an explanation of the issues. It became clear why we were having issues sources a quintet of boards so that we could deliver on our prize offer.

    To further compound problems we a somewhat smaller issue sourcing Spark Core boards. We put in an order for a quintet of them when we posted the contest; at the time they were supposed to be shipping in late March, but now shipping estimates have been delayed to mid-April. Assuming no more delays these should be available by the time the contest ends at the end of April so keep your fingers crossed.

    We have a good relationship with the folks over at Spark Core and can probably ask them to help us out if we do get in a bind. But we don’t think anyone is going to be able to deliver the BeagleBone Black boards (which we have on backorder) in time for the end of the contest. So here’s the deal: if you win and really want these exact boards in the prize package you select, we’re going to do what needs to be done to get it for you, eventually. If you don’t want to wait and there is a suitable alternative we’ll make that happen.

    We wondered what people are doing if they don’t want to wait out these shortages. Are there any other open-hardware projects that are similar in price and functionality? Our gut says no (that’s why they’re in such high demand). But we’d love to hear about some alternatives. Let us know by leaving a comment below.

    Turn a Trash Can Into an EVE Costume

    eve costume

    EVE is one of the most charming characters in WALL-E, and when Instructables user drwave’s daughter wanted to dress like her for Halloween, he took charge and built it. It all started with a trash can, and the costume is an inspiring example of using everyday objects in cosplay. He paired the trash can with EL wire, a paper lantern, and more. Making the shoulder supports was the trickiest part of the build, but he figured it out:

    We decided the best way would be to build some “wings” that would sit atop the wearer’s shoulders. This is the strongest and leads to the least fatigue of any of the ideas we came up with.

    To make it work, we started with a plastic top from an IKEA container, and using a Skil saw, cut out two wings that we bolted to the inside of the can, above the arm holes. Another important thing here was to get some foam (that we covered with fabric) and attach it to the wings where they will rest on the shoulders. We attached the fabric to the foam and then that to the wings with hot glue, but we used two bolts and washers to attach each wing to the can.

    The Beautiful Imagery of Alejandro Jodorowsky’s #Dune

    dune

    Frank Herbert’s Dune is a sweeping epic filled with alien worlds and beings. Not only are the landscapes rich, so are the characters and costumes and politics. The story has been adapted for the screen a few times, but Alejandro Jodorowsky’s unique vision never made it to completion. His take was surreal. He wanted viewers to feel as though they were tripping without any drugs. Concept art showcased by BoingBoing shows off Jodorowsky’s plan, and so does the new documentary titled Jodorowsky’s Dune.

    Adafruit is focusing its Halloween celebration and plans around Dune this year, so it’s only appropriate to give this documentary attention. You’ll be intrigued by Jodorowsky’s imagination and perhaps it will inspire you to come up with a new Dune costume!

    High Tech Convertible Desk Takes it Up a Notch

    desk

    Standing desks seem to be all the rage today — but do you really want to commit fully to always standing? [Jeff Minton] didn’t, and when he found out how much convertible standing desks cost… he decided to make his own.

    While brainstorming ways of accomplishing this he started browsing around eBay and found 18″ linear actuators for sale. They were $45 each, ran at 24V and could lift 600lbs each. Bingo. Actually, that’s kinda overkill…

    He picked up a 24V power supply, an Arduino, and a 8-channel relay board.  The actuators are attached to the desk’s original legs using U-bolts which keep the legs straight and take the load of the desk. The untreated wood supports are there to reinforce the original desk, because they weren’t that sturdy in the first place.

    It takes about a minute to fully actuate the legs, so while it’s not the prettiest nor the quickest solution — it does the trick and allows you to easily switch between standing and sitting.

    Maybe he should try over-powering the actuators since the load is so small — could make it go a bit faster! And if you’re looking for a cheaper and more permanent solution, extended PVC legs do the trick too.

    NEW PRODUCT – Anemometer Wind Speed Sensor w/Analog Voltage Output

    1733

    NEW PRODUCT – Anemometer Wind Speed Sensor w/Analog Voltage Output: An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease.

    To use, connect the black wire to power and signal ground, the brown wire to 7-24VDC (we used 9V with success) and measure the analog voltage on the blue wire. The voltage will range from 0.4V (0 m/s wind) up to 2.0V (for 32.4m/s wind speed). That’s it! The sensor is rugged, and easy to mount. The cable can easily disconnect with a few twists and has a weatherproof connector.

    In stock and shipping now.

    MarkMiller

    Mark Miller shared:

    My latest version of the CNC lathe for wood and plastics. This model uses the Ps2 joystick teach system I have been making and allows you to manually create a part and then make copies of that part as the data for the movements are stored as you create the part. The board with the display on the left is the DRO which indicate position of the X and Y, you push the joystick down to toggle between them. A hex file is created as you create the original, and is transferred to a PIC. I have made several more versions of this and am currently making a small mill, drill and foam cutter that will use the same system. The entire machine is mostly made of Lexan bits and pieces and a few inexpensive motors.

    Bongo Lee shared: “Got a Canon A2400 power shot a month ago. Got the CHDK firmware working on it very happy with the results. If you haven’t heard about CHDK it’s really worth looking at. It enables you to access the raw power of the camera. You can get the functionalities you would usually find on a DSLR camera on to a cheap point n shoot camera. The camera’s battery is puny and had only enough juicy for maybe an hour. Not enough if you want to take time lapse shots. So saw a few hacks where you can replace the battery with a dummy one and connect it to a external power source. The same product is available from canon for a price of 70$!!! That’s inane given that the camera itself costs just about 100$ So gave it a shot with what I had lying around at my home and this is what I came up with.” (read more)

I like to keep my colors separated, so once you have done that, take a closer look at the inside of one of the pieces. You see the two little knubs sticking out a bit from the inside walls? Those have got to go so grab that Exacto Knife and carefully cut off those little knubs (Please if you are a wolf cub allow your parents to do this for you). After you cut off all those knubs place two pieces together and move them back and forth. Hear anything? No? Great! Now then, turn them over so that the single flat end faces you. Clamp them down tightly and drill a hole all the way through. Take the drilled out piece and place it on top of the dual end of another component. Mark where the hole is and drill through both ends. Repeat this for all the pieces you plan on using for your tail.” (read more)


    Artist and maker Dmitry Morozov sent us a blog tip about his latest project: a sound controller that uses a tattoo as a music score.

    Eduardo Zola shared a video and tutorial details for creating A Tetris Rig with a Pair of Adafruit NeoPixel Matrices: “Since I started with arduino, i always wanted to make a game based on this platform. So one day I thought, why not create an old classic Tetris ? I remember to play it a lot in old times, mainly in windows 3.1 and 95 ages. So, the first thing i needed to start the project, was to find out a RGB display, push buttons or a small joystick, and an enclosure to attach everything. After some research, I found out the Adafruit Neopixel Matrix 8×8, which is very easy to apply because it uses a just a single wire interface and simple handy library. So, I used two matrix of this, which gave me a display of 16 rows and 8 columns of RGB LED (or pixels). For powering, I used a Lithium Ion Battery of 3.7V 4400mAh. It was really necessary to put a capacitor (1000 µF, 6.3V or higher) across the positive and negative terminals of neopixel matrix….” (read more)


    Eagleeye2e

    eagleeye2e shared a how-to for bringing some Adafruit interactive bling to his son’s Pinewood Derby car on the Adafruit Forums: “We decided to add a little high-tech flash to my son’s Pinewood Derby car this year. This project involved several Adafruit products including a 3.3v Trinket, a NeoPixel stick, a FLORA Accelerometer/Compass Sensor, and a Lithium Ion Polymer Battery. All of these components were chosen for their size and their light weight. The idea was to have a subtle yellow glowing effect under the car while it was at rest and while the car was in motion going down the track the pixels scroll from front to back with a brighter, different, color. The faster the car goes, the faster the pixels scroll. In addition, every time the car goes from scroll to rest, the color of the scrolling pixels changes to a new color for the next race. The car received many complements and oooh’s and ahhh’s. Thank you Adafruit for all of the great products that allowed us to add something fun and unique to our Pinewood Derby experience!” (read more)

    Instructables user brokenpipe created a one man version of the parade in a costume: “In Illustrator, I made a template to mark out all of the holes that I’ll need to drill to mount each ball [ping pong ball]. The balls I ordered were 38mm in diameter. Apparently, in 2000 it was decided that the “official” size of a ping pong ball would increase from 38mm to 40mm. It doesn’t matter whick size you choose, as long as you know what you’ve got. In my template, I added an extra 2mm between each ball just to allow some room for error when mounting the balls. I needed a firm base which would be large enough for the matrix so I went a local Target to see what I could find. I ended up getting a black plastic drain board. As you can see from the image, the size worked pretty well.” (read more)

    This Tiny Arcade Machine Holds a Raspberry Pi @Raspberry_Pi #piday #raspberrypi

    This tiny desktop arcade is fully functionally thanks to a raspberry pi, from eetimes.

    For many of us, there is a certain wonderful feeling that bubbles to the surface when we think of arcades. The many hours spent huddled around a game, pouring our hard-earned quarters into the machine. The shouts of frustration as your friends can’t beat your high score. The ridiculously sore fingers from mashing those buttons for far too long. Unfortunately, recapturing even a bit of that fun is difficult.

    Steve Smith managed to come up with a great way to recapture a bit of his arcade fun. He decided to put an arcade cabinet on his desk. This itty-bitty arcade machine you see is fully functional and loaded with games. Housed inside the tiny cabinet is a Raspberry Pi loaded with Mame, an emulator for a game system.

    This specific version of Mame is called PiMame and can emulate several different video gaming systems. You can find more information on PiMame here, if you want to run it on your Raspberry Pi.

    Make an inexpensive wi-fi enabled media center for your car using Raspberry Pi! #piday #raspberrypi @Raspberry_Pi

    NewImage

    MAKE has a great new tutorial up for a Raspberry Pi powered car computer.

    I have always loved those old TV series with futuristic tech in those futuristic vehicles, like Knight Rider, Airwolf, and Street Hawk. So it got me thinking about how easy it would be to add a computer to a vehicle. Now I know it’s been done before, and a quick Google search shows multiple companies making very complex vehicle computers, but at a large cost.

    Well, I thought, my Raspberry Pi is the perfect device for this.

    • It’s cheap
    • It’s very small
    • It’s got small power requirements (runs off a micro USB car charger)
    • It’s got flexible video and audio outputs (HDMI and Composite RCA for video, HDMI and 3.5mm audio jack for audio)
    • And best of all, you can change operating systems by simply switching out SD cards.

    Below is a photo of the Raspberry Pi running the excellent media center-type operating system Raspbmc which is perfect for browsing and playing your media collection using a media center remote or something similar, as shown in the Parts list.

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413. Running out of pins on your Arduino? Get this!

    Microcontrollers 1551 Lrg

    Tutorial – Adafruit 1-Wire GPIO Breakout – DS2413 @ Adafruit Learning System.

    Pins are precious in the microcontroller world. How many times have you needed just one more pin? Sure, you could step up to a Mega and get a whole bunch more, but what if you really just need one or two? The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one. But you can keep expanding from there.

    You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin. Each chip has a 48-bit unique address, which means (in theory*) you could have as many as 2 * 2^48 pins controlled by just one Arduino pin! What could you control with 562 trillion pins?

    Learn more! and pick up one in the Adafruit store!
