There’s a new documentary series on Al Jazeera called Rebel Geeks that looks at the people who make the stuff everyone uses. The latest 25-minute part of the series is with [Massimo], chief of the arduino.cc camp. Upcoming episodes include Twitter co-creator [Evan Henshaw-Plath] and people in the Madrid government who are trying to build a direct democracy for the city on the Internet.
Despite being a WiFi device, the ESP8266 is surprisingly great at being an Internet of Thing. The only problem is the range. No worries; you can use the ESP as a WiFi repeater that will get you about 0.5km further for each additional repeater node. Power is of course required, but you can stuff everything inside a cell phone charger.
I’ve said it before and I’ll say it again: the most common use for the Raspberry Pi is a vintage console emulator. Now there’s a Kickstarter for a dedicated tabletop Raspi emulation case that actually looks good.
Pogo pins are the go-to solution for putting firmware on hundreds of boards. These tiny spring-loaded pins give you a programming rig that’s easy to attach and detach without any soldering whatsoever. [Tom] needed to program a few dozen boards in a short amount of time, didn’t have any pogo pins, and didn’t want to solder a header to each board. The solution? Pull the pins out of a female header. It works in a pinch, but you probably want a better solution for a more permanent setup.
Half of building a PCB is getting parts and pinouts right. [Josef] is working on a tool to at least semi-automate the importing of pinout tables from datasheets into KiCad. This is a very, very hard problem, and if it’s half right half the time, that’s a tremendous accomplishment.
Last summer, [Voja] wrote something for the blog on building enclosures from FR4. Over on Hackaday.io he’s working on a project, and it’s time for that project to get an enclosure. The results are amazing and leave us wondering why we don’t see this technique more often.
There are a surprising number of Raspberry Pis being used in industrial equipment. This means the Arduino is left behind, but no longer. There’s your PLCs that use Arduinos.
A few weeks ago, Google introduced a machine intelligence and computer vision technique that made the world look psychedelic. Now, this library is available. On another note, head mounted displays exist, and a sufficiently creative person could mash these two things together into a very, very cool project.
Welcome to Kickstarter! Kickstarter is an uphill battle. People will doubt you because you don’t have a ‘target audience’ or ‘the rights to this franchise’ or ‘any talent whatsoever’, but that’s what crowdfunding is for!
Several years ago, Apple shipped a few million 17″ iMacs with defective displays. They’re still useful computers, though, especially if you can find a replacement LCD. Apple, in all its wisdom, used a weird connector for this LCD. Here’s the adapter board, and this adapter will allow displays running up to 1920×1200.
[Jan] has earned a reputation of building some very cool synths out of single ARM chips. His previous build was a Drumulator and now he’s shrinkified it. He’s put four drum sounds, pitch CV, and audio out on an 8-pin DIP ARM.
YouTube gives you cadmium! [AvE], recently got 100,000 subscribers on his YouTube channel. Apparently, YouTube sends you a terrible belt buckle when you manage to do that. At least he did it without playing video games and screaming.
[Burt Rutan] is someone who needs no introduction. Apparently, he likes the look of the Icon A5 and is working on his own version.
Earlier this week, the US Air Force lost a few satellites a minute after launch from Barking Sands in Hawaii. This was the first launch of the three stage, solid fueled SPARK rocket, although earlier versions were used to launch nuclear warheads into space. There are some great Army videos for these nuclear explosions in space, by the way.
[Alexandre] is working on an Arduino compatible board that has an integrated GSM module and WiFi chip. It’s called the Red Dragon, and that means he needs some really good board art. The finished product looks good in Eagle, and something we can’t wait to see back from the board house.
The Chippocolypse! Or however you spell it! TI is declaring a lot of chips EOL, and although this includes a lot of op-amps and other analog ephemera (PDF), the hi-fi community is reeling and a lot of people are stocking up on their favorite amplifiers.
[Jeremy] got tired of plugging jumper wires into a breadboard when programming his ATMega8 (including the ‘168 and ‘328) microcontrollers. The solution? A breadboard backpack that fits right over the IC. All the files are available, and the PCB can be found on Upverter.
In case you haven’t heard, we’re having a Super Conference in San Francisco later this week. Adafruit was kind enough to plug our plug for the con on Ask an Engineer last week.
It seems almost compulsory that we start off with a dose of Star Wars. Here’s an epic AT-ST build that motorizes the iconic walker.
That two-legger isn’t going to be lonely. It bigger-slower brother, the AT-AT got a bit of motorized love as well.
What? You were expecting a BB8 build? We have one of those too. [DrYerzinia] has begun a design that hides a quadcopter inside of the BB8. The four 17″ DJI propellers fold up when not in use, extending through hatches in the outer shell when it’s time to take flight. This retains the rolling design you’ve already come to love in the BB8 and we’re going to keep our eyes on it!
Do you have a Teensy and some extra WS2812 strips hanging out on your bench? [etix] put his to use with an ambilight clone. This works really well: simple hardware which connects via USB to communicate with VLC. We applaud [etix’s] choice of Kung Fury as a demo video… a truly bizarre and entertaining short movie. +1000 for its use of VHS tape artifacts.
We just missed Halloween, but this set of wings is far too great of a build to be reserved for that one day. Alas, there is only the demo video but seeing the huge feathered structures fold and unfold is really impressive!
[Truebass] added an artistic accent to one of the walls in his home. He had several cellphone chargers from old phones in his junk bin. These were used to regulate power for some white LEDs. The finished sconces are made from chip-board covered in cherry veneer, all leftover from previous projects.
Want to drink your beer out of beer-byproducts? How about your coffee out of coffee-byproducts. It sounds strange, but 3DOM is marketing it that way, encouraging you to print your beer stein with this beer-byproduct-based 3D printer filament. They also offer coffee filament and have plans for future oddball building materials. Printer inception?
We ran a post about the secret computer of the New York subway system. There wasn’t a ton of information there, but that could change. The New York Historical Society is running a Kickstarter to expand their Computing History made in NY.
There are dozens of different 3D printable cases out there for the Raspberry Pi, but the BeagleBone Black, as useful as it is, doesn’t have as many options. The folks at 3D hubs thought they could solve this with a portable electronics lab for the BBB. It opens like a book, fits a half-size breadboard inside, and looks very cool.
The guy who 3D printed his lawnmower has a very, very large 3D printer. He now added a hammock to it, just so he could hang out during the very long prints.
There’s a box somewhere in your attic, basement, or garage filled with IDE cables. Wouldn’t they be useful for projects? Yep, only not all the wires work; some are grounds tied together, some are not wired straight through, and some are missing. [esot.eric] has the definitive guide for 80-wire IDE cables.
Like case mods? Here’s a golden apple, made out of walnut. Yes, there are better woods he could have used. It’s a wooden replica of a Mac 128 with a Mac Mini and LCD stuffed inside. Want a video? Here you go.
If you have a 3D printer, you’re probably familiar with PEEK. It’s the plastic used as a thermal break in non-all-metal hotends. Now it’s a filament. An extraordinarily expensive filament at €900 per kilogram. Printing temperature is 370°C, so you’ll need an all-metal hotend.
It’s the Kickstarter that just keeps going and going and going. That’s not a bad thing, though: there really isn’t much of a market for new Amiga 1200 cases. We’ve featured this project before, but the last time was unsuccessful. Now, with seven days left and just over $14k to go, it might make it this time.
We have our featured speakers lined up for the Hackaday Supercon, one of which is [Fran Blanche]. We’ve seen a lot of her work, from playing with pocket watches to not having the funding to build an Apollo Guidance Computer DSKY. In her spare time, she builds guitar pedals, and there’s a biopic of her in She Shreds magazine.
Halloween is coming, and that means dressing children up as pirates, fairies, characters from the latest Marvel and Disney movies, and electrolytic capacitors.
There’s a new movie on [Steve Jobs]. It’s called the Jobs S. It’s a major upgrade of the previous release, featuring a faster processor and more retinas. One more thing. Someone is trying to cash in on [Woz]’s work. This time it’s an auction for a complete Apple I that’s expected to go for $770,000 USD.
Hackaday community member [John McLear] is giving away the factory seconds of his original NFC ring (think jewelry). These still work but failed QA for small reasons and will be fun to hack around on. You pay shipping which starts at £60 for 50 rings. We’ve grabbed enough of them to include in the goody bags for the Hackaday Superconference. If you have an event coming up, getting everyone hacking on NFC is an interesting activity. If you don’t want 50+, [John] is also in the middle of a Kickstarter for an improved version.
Your 3D printed parts will rarely come out perfectly. There will always be some strings or scars from removing them from the bed. There’s a solution to these problems: use a hot air gun.
Everyone has a plumbus in their home, but how do they do it? First, they take the dinglebop, and smooth it out with a bunch of schleem. The schleem is then repurposed for later batches.
[Kratz] just turned into a rock hound and has a bunch of rocks from Montana that need tumbling. This requires a rock tumbler, and why build a rock tumbler when you can just rip apart an old inkjet printer? It’s one of those builds that document themselves, with the only other necessary parts being a Pizza Hut thermos from the 80s and a bunch of grit.
Boot a Raspberry Pi from a USB stick. You can’t actually do that. On every Raspberry Pi, there needs to be a boot partition on the SD card. However, there’s no limitation on where the OS resides, and [Jonathan] has all the steps to replicate this build spelled out.
Some guys in Norway built a 3D printer controller based on the BeagleBone. The Replicape is now in its second hardware revision, and they’re doing some interesting things this time around. The stepper drivers are the ‘quiet’ Trinamic chips, and there’s support for inductive sensors, more fans, and servo control.
Looking for one of those ‘router chipsets on a single board’? Here you go. It’s the NixCoreX1, and it’s pretty much a small WiFi router on a single board.
[Mowry] designed a synthesizer. This synth has four-voice polyphony, 12 waveforms, ADSR envelopes, a rudimentary sequencer, and fits inside an Altoids tin. The software is based on The Synth, but [Mowry] did come up with a pretty cool project here.
