2015 was the year of the unofficial hardware badge at DEF CON 23. There were a ton of different hardware badges designed for the love of custom electronics and I tried to catch up with the designer of each different badge. Here is the collection of images, video demos, and build details for each one I saw this weekend.
Gorgeous text treatment on back of this badge is indicative of [True’s] mastery
[TrueControl] did a great job with his badge design this year for the Whiskey Pirate Crew. This is a great update from the badge he designed last year, keeping the skull and bones outline. It uses a PSOC4 chip to control a ton of LEDs. The eyes are RGB pixels which are each on their own PCB that is soldered onto the back of the badge, with openings for the LED to show through. Two AA batteries power the board which has a surface-mount LED matrix. The user controls are all capacitive touch. There is a spinner around one eye, and pads for select and back. The NRF24L01 radio operates at 2.4GHz. This badge is slave to commands from last year’s badge. When the two are in the same area the 2015 badges will scroll the nickname of the 2014 badge it “sees”. The piezo element also chirps many different sounds based on the interactions with different badges.
[True] makes design an art form. The matte black solder mask looks fantastic, and he took great care in use of font, size, alignment, and things like letting copper show through for a really stunning piece of hardware art.
Keep reading for ten more great badges seen over the weekend.
This past weekend the Maker Faire returned to the motor city. While it seemed a bit smaller than previous years, the event still brought in a ton of awesome makers from the metro Detroit area and beyond.
Although we don’t feature too many woodworking projects, there were quite a few woodworkers at the Faire with projects ranging from custom longboards pressed with a home built iron mold to DIY kayaks with elaborate wooden skeletons built by a local group of Michigan kayak builders. The kayaks were quite impressive: hand sewn nylon panels are wrapped around custom frames made from steamed white oak. It’s great to speak with the makers about the specialized skills needed for kayak building.
Last week we challenged you to post your idea on environment-related solutions for the 2015 Hackaday Prize. We’ve gone through every entry and have chosen this week’s winners. What a tough process, there are so many interesting ideas to consider that we’ve done a round-up of some that held our attention.
Conservation was at the center of these projects and [Peter Walsh] is thinking large scale to improve the Bosch-Haber process. This process is used as a source of nitrogen for fertilizers and consumes 1% of all energy worldwide. Even small efficiency advances could have a huge effect.
From profound to whimsical, [TomaCzar] has an alarming solution to leaving the lights on. We enjoy his preamble about his family moving to Earth from a planet with unlimited energy (hence their habit of leaving the lights on). He plans to add an audible alarm to any light that is switched on for more than 10 minutes.
Those huge solar farms that use arrays of mirrors to focus the sun’s light on a central tower leverage a techique called Concentrated Solar Power. Traditionally they store heat in a pool of liquid salt for generating power around the clock. [PUNiSH3R] has a plan to build his own on a micro-scale. The Portable Micro-CHP will use similar concepts (less the molten salt) in a package small enough to be transported by a single human.
Undeveloped parts of the planet have huge problems when it comes to bootstrapping an electrical grid. [hickss] thinks blimps might be one way to alleviate the problem. The DayBreaker project will tether blimps to the ground, with a hydrogen feed supplied through electrolysis which keeps them afloat. While high in the air they can catch higher winds using a turbine and transfer the electricity back to the ground using the same tether.
Rounding out energy producing examples is the Domestic Geothermal Stirling Power Unit. We’ve seen geothermal systems that use heat exchangers to heat or cool your home. [Shrad] ponders the idea of also using the loops of circulating fluid to feed a Stirling engine that could help supply power to the home.
Way Out There Ideas
There were a number of interesting concepts that we think are well worth considering and debating. It’s hard to say if these are all feasible, but tossing the ideas around is just the kind of interaction that could lead to a big breakthrough. For instance, the image seen here is a freshly paved and painted asphalt parking lot. Asphalt Heat Harvesting imagines the Peltier effect being used on a large scale by embedding metal networks between layers of the pavement. A heat differential between the surface and the base layer could produce electricity.
We’re at a loss for understanding how the Open Source Modular Absorption Refrigeration Unit actually works. It seeks to supply refrigeration using a heat source instead of electricity. The diagram looks promising and we think OSMARU is a solid acronym!
Remember The Hunt for Red October? If so, you certainly remember the caterpillar drive which made the submarine virtually silent. [N-Monkeys] wants to use that and ocean water as a generator rather than a locomotive device. Check out Project InchWorm.
Congratulations to all three! We think it’s important to mention we are judging the idea on its ability to solve something affecting a wide range of people, its level of innovation, and the feasibility of the concept. There is no requirement at this point to have built anything or completed the documentation. Don’t be afraid to write down your own brainstorm… it might just win you a prize!
Next Week’s Theme
We’ll announce next week’s theme a bit later today. Don’t let that stop you from entering any ideas collection of entries may have inspired.
It’s easy to get sucked into the increasing the complexity when sometimes the craftsmanship can be what makes the project. [Alex Weber] proves the point with his minimalist marble machine. There are no death-defying twists and turns, no convoluted path forks or overly-complex lifting mechanisms. This is about a clean and simple design that looks amazing whether running or stationary.
Have we scared you off from building these yourself yet? No, that’s the entire point of this one… it can be excruciatingly simple, while elegantly crafted. Check out the video demo below to see how one oval, one battery, and one motor have no problem bringing a smile to your face.
Most of our energy comes from dead algae or dead ferns right now, and we all know that can’t continue forever. The future is by definition sustainable, and if you’re looking for a project to change the world for this year’s Hackaday Prize, you can’t do better than something to get the world off carbon-based fuels.
Building the machines that make sustainable energy possible or even just the tools that will let us use all that energy are just a few ideas that would make great entries for The Hackaday Prize. You could go another direction and build the tools that will build and maintain these devices, like figuring out a way to keep these batteries and generators out of the landfill. Any way you look at it, anything that actually matters would make a great entry to The Hackaday Prize.
It’s not as flashy as Tesla coils or electric vehicles going 200 mph, but the environment is more important than a bunch of cool baubles and sparks flying everywhere. When it comes to this year’s Hackaday Prize, you’re going to need a project that matters, and what’s a better way to do it than with something to help the environment?
While not traditionally a domain that rocks people’s socks, there are a lot of cool builds that can help the environment like this hyperspectral imager that’s a mashup of a spectrometer and a camera, or something that takes an image of an object, complete with the spectral data of each pixel. It’s useful for everything from farming, to forestry, to medicine.
And now it’s time to recognize a big part what makes the Hackaday Prize possible: our Judges and our Sponsors. First up are the Judges. We are fortunate again this year to be joined by top experts from around the world. We are going to briefly touch on each in this post, but you really should hit the Judge’s page for bios and links on everyone.
Welcome back, and so happy to have the new Judges this year!
