Gaze Upon This Daft Punk Helmet’s Rows Of Utterly Perfect Hand-Soldered LEDs

The iconic robot helmets of Daft Punk feature prominently as challenging DIY hardware projects in their own right, and the results never disappoint. But [Nathaniel Stepp]’s photo gallery of his own version really sets the bar in both quality and attention to detail. The helmet uses a Teensy 3.2 as the main processor, and the visor consists of 328 hand soldered through-hole APA106 addressable RGB LEDs. A laser cut panel serves as the frame for the LEDs, and it was heat-formed to curve around the helmet and mate into the surrounding frame. Each LED is meticulously hand-soldered, complete with its own surface mount decoupling cap; there’s no wasted space or excess wire anywhere to be seen. It looks as if a small 3D printed jig was used to align and solder the LEDs one or two columns at a time, which were then transferred to the visor for final connections with the power bus and its neighboring LEDs.

After the whole array was assembled and working, the back of each LED appears to have then been carefully coated in what looks like Plasti-Dip in order to block light, probably to minimize the blinding of the wearer. A small amount of space between each LED allows the eyeballs inside the helmet to see past the light show in the visor.

The perfectly done array of LEDs in the visor is just one of the design elements showing the incredible workmanship and detail in [Nathaniel]’s helmet. His website promises more build details are coming, but in the meantime you can drink in the details shown in the aforementioned photo gallery.

With Halloween approaching, you might be interested in rolling your own Daft Punk inspired helmet. Not ready to do everything from scratch? No problem, because it’s never been easier to make your own with the help of a 3D printer and some LED strips.

Maker Faire NY: Programmable Air

At this year’s World Maker Faire in New York City we’re astonished and proud to run into some of the best projects that are currently in the running for the Hackaday Prize. One of these is Programmable Air, from [Amitabh], and it’s the solution to pneumatics and pressure sensing in Maker and IoT devices.

The idea behind Programmable Air is to create the cheapest, most hacker-friendly system for dealing with inflatable and vacuum-based robotics. Yes, pneumatic robotics might sound weird, but there’s plenty of projects that could make use of a system like this. The Glaucus is one of the greatest soft robotic projects we’ve ever seen, and it turns a bit of silicone into a quadruped robot with no moving parts. The only control you have over this robot is inflating one side or the other while watching this silicone slug slowly crawl forward. This same sort of system can be expanded to a silicone robot tentacle, too.

On display at the Programmable Air booth were three examples of how this device could be used. The first was a simple pressure sensor — a weird silicone pig with some tubing coming out of the nostrils was connected to the Programmable Air module. Squeeze the pig, and some RGB LEDs light up. The second demo was a balloon inflating and deflating automatically. The third demo was a ‘jamming gripper’, basically a balloon filled with rice or coffee grounds, connected to a pump. If you take this balloon, jam it onto an odd-shaped object and suck the air out, it becomes a gripper for a robotic arm. All of these are possible with Programmable Air.

Right now, [Amitabh] has just finalized the design and is getting ready to move into mass production. You can get some updates for this really novel air-powered robotics platform over on the main website, or check out the project over on Hackaday.io.

All The Badges Of DEF CON 26 (vol 2)

There were so many amazing unofficial badges at DEF CON this year that I can’t possibly cover them all in one shot. I tried to see every badge and speak with every badge maker — like a hardware safari. Join me after the jump for about fourteen more badges that I saw at DEF CON 26!

If you missed the first batch, check those badges out too — there’s even a Badgelife Documentary that you need to add to your watch list. Okay, let’s dig in.

Coolest Way To Watch 3D Printing: Lights, Camera, Octolapse!

Octoprint is a household name for anyone into 3D printing and anyone regularly reading Hackaday. Described by creator Gina Häußge as “the snappy web interface for your 3D printer”, Octoprint allows you to control effectively any desktop 3D printer over the local network or Internet. It even has webcam support so you can watch your printer while it works, meaning you can finally put that video baby monitor back into the crib with Junior.

While the core functionality of Octoprint is fantastic alone, its true power is unlocked through the plugin system and the community that’s sprung up around it. With plugins, Octoprint can do everything from control RGB light strips in your printer’s enclosure to sending status messages via Discord. One particularly popular plugin that has been making the rounds lately is Octolapse by [FormerLurker]. This plugin provides a comprehensive intelligent system for creating time-lapse videos of prints.

What does that mean? Well, instead of simply taking a picture every few seconds like you’d do traditionally, Octolapse actually keeps track of the printer’s motions while its running. It can then take a picture at the opportune moment to create a number of user-selected effects. More importantly, it can even take control of the printer directly; moving the hotend away from the print before taking a picture. The effect is that the print simply “grows” out of the bed.

I thought it would be interesting to take a closer look at Octolapse and see just what it takes to create one of those awesome time-lapse videos. It turned out to be somewhat trickier than I anticipated, but the end results are so fantastic I’d say it’s a technique worth mastering.

Hackaday Links: Benchoff Rants On Flying Cars

It’s time for Computex, and that means [Linus] has dropped something. I don’t know what, but he’s dropped something. It’s a meme or something at this point. What were the highlights? Asus announced Project Precog, a laptop with two screens. Yes, a touchscreen keyboard. It’s the 2018 version of the IBM Transnote or whatever that Microsoft thing was called. Why is it called Project Precog? Because AI or whatever. Unimaginative marketing is terrible. Intel is going to launch a 28-core CPU, and AMD is introducing a 32-core CPU. Awesome, core wars. And here’s RGB RAM because stuffing a case full of cold cathode lighting is sooo early-2000s.

Need a reverse engineering challenge? Here’s something from American Science and Surplus. It’s a 48 x 12 LED matrix, loaded up with driver ICs and power regulators. $20 a piece, so stock up and save.

Finally, the main event. The biggest story in aviation this week is that a media embargo has lifted on the Kitty Hawk Flyer. Kitty Hawk is a startup funded by Larry Page, CEO’d by Sebastian Thrun, and has received $6.5 M in funding. The Flyer, a one-man decacopter, was announced to the world through CNN Money and Casey Neistat. It should be noted that in the entire media landscape, these are the two outlets most ignorant of aviation: CNN needs no explanation, and Neistat flies quadcopters through the Hudson River Corridor at 1000 feet AGL. Additionally, Kitty Hawk is not exhibiting at AirVenture next month, which leads me to believe Kitty Hawk is trying to stay out of the aviation industry or simply doesn’t want knowledgeable people asking them questions. But I digress.

The Kitty Hawk Flyer is being promoted by the company as “a personal flying vehicle… to make flying part of everyday life” and a machine that will give you, “a world free from traffic”. It is being billed by CNN and Neistat as ‘a flying car’. Kitty Hawk is just fine with allowing the media to call it as such. Additionally, Sebastian Thrun is making claims about the Flyer that are disingenuous at best, outright illegal at worst, and should draw the ire of any investors.

In the CNN Money piece, Thrun claims the Flyer is capable of traveling at 100 miles per hour, which would be illegal. The Flier is certified as a Part 103 Ultralight, and under that regulation the Flyer “is not capable of more than 55 knots calibrated airspeed at full power in level flight.” The Flyer may also be overweight. The first version of the Flyer was basically a decacopter with a seat, and weighed in at 220 pounds. Part 103 regulations have a limit of 254 pounds, and it’s entirely possible there are more than 34 pounds of chassis and fiberglass on the latest version. I should also mention the safety training, while not required for a Part 103 ultralight, is insufficient: Casey Neistat’s underwater egress training was done in a Chuck E. Cheese-style ball pit. You can breathe in a ball pit, you can’t breathe underwater.

But legality aside, a Part 103 ‘flying car’ is just about the dumbest idea ever. You can’t use it to commute, and you’re welcome to call your local FSDO to confirm that. You’re not going to fly it in New York City or San Francisco because there are airports in the way. At best, this is a ‘flying ATV’ that you would take out on your farm; a toy for rich people. At worst, it’s the latest example of the Silicon Valley philosophy of ‘ignore laws and break things’.

Hackaday Belgrade Schedule Announced

Hackaday Belgrade preparations have now passed the flash point and the hacker village that is set to descend on Serbia in a few weeks grows larger and more awesome by the day. Prepare for a massive data dump on what is in store. But before you go any further, make sure you have a ticket.

Lasers, Mirrors, And Sensors Combine In An Optical Bench Game

Who would have thought you could make a game out of an optical bench? [Chris Mitchell] did, and while we were skeptical at first, his laser Light Bender game has some potential. Just watch your eyes.

The premise is simple: direct the beam of a colored laser to the correct target before time runs out. [Chris] used laser-cut acrylic for his playfield, which has nine square cutouts arranged in a grid. Red, green, and blue laser pointers line the bottom of the grid, with photosensors and RGB LEDs lining the grid on the other three sides. Play starts with a random LED lighting up in one of the three colors, acting as a target. The corresponding color laser comes on, and the player has to insert mirrors or pass-through blocks in the grid to create a path to the target. The faster you hit the CdS cell, the higher your score. It’s simple, but it looks really engaging. We can imagine all sorts of upgrades, like lighting up two different targets at once, or adding a beamsplitter block to hit two targets with the same color. Filters and polarizers could add to the optical fun too.

We like builds that are just for fun, especially when they’re well-crafted and have a slight air of danger. The balloon-busting killbots project we featured recently comes to mind.
