We rolled into Detroit this morning and immediately wanted to know what the teams for the Red Bull Creation were up to. But first thing’s first, what’s the surprise theme? [Brian Benchoff] caught up with [Tyler Hansen] and [Jason Naumoff] who filled us in. The theme is “Reinvent the Wheel”.
The seven finalist teams are competing in a live, non-stop build which started yesterday and continues until tomorrow evening.
There are many very cool visual effects for music, but the best are the kind you build yourself. [Ben’s] mini LED volume towers adds some nice bling to your music.
[Ben] was inspired to created this project when he saw a variety of awesome stereo LED towers on YouTube (also referred to as VU meters). We have even featured a few VU meters, one very recently. [Ben] goes over every detail, including how to test your circuit (a very important part of any project). The schematic is deceptively simple. It is based on the LM3914 display driver IC, a simple chained comparator circuit is used to control the volume bar display. All you really need is a 3D printer to make the base, and you can build this awesome tower.
See the completed towers in action after the break. What next? It would be cool to see a larger tower that displays frequency magnitude!

We’re a little under a month until the first cutoff date for The Hackaday Prize, and there have been a few questions we’ve been answering again and again: ‘what does ‘connected’ mean?’ and, ‘do I really have enough time to build something for The Hackaday Prize?’ Lucky for you, [Matt] from Electric Imp put together a very short demo of a sample THP entry. It’s a ‘HACKING’ light, kind of like an ‘on air’ light you’d find in a TV or Radio studio.
The idea for the project came from a tweet to [Matt] that seemed simple enough to implement. After grabbing an Imp and a breakout board, a LED, button, and resistor were wired up, with power supplied over USB. The code for the device was simple enough, and the Imp makes it easy to make that ‘hacking’ button tweet and serve a simple web page.
[Matt] pulled this project together in an afternoon, and although it’s not nearly as complex as the 3D printers, CNC machines, and freakin’ tricorders that are also entered into The Hackaday Prize, it meets all the requirements we’re looking for.
Of course, ‘connected’ is a very broad term, and even if you have a project that communicates with LEDs, a serial connection, or even pigeons, it’ll be more than enough to tick that ‘connected’ check box.
There’s still a few weeks until the first cutoff date for The Hackaday Prize, so get moving.

Have you voted in the second round of Astronaut or Not? You’d better get in there by Friday at 9pm EDT or miss your chance to win a Bukito Portable 3D Printer in the voter’s lottery.
You must vote at least once per round to be eligible. At the appointed time we’ll draw a random number and look up to see if that profile on Hackaday.io has voted. If so, winner winner (like the Rigol scope that was awarded last Friday). If not, no Bukito for you! This new round just started at the beginning of the week. Your vote quota has been restored, and we tweaked the interface to only show you each project once.
In addition to your own gain, you’re helping us choose which projects deserve a bit of swag. We’re one again sending shirts to the projects who rise to the top of the head-to-head gudgematch.
UPDATE: To clarify, you must vote in the current round to be eligible for the current voter lottery. Your participation in previous rounds has no bearing on the current round eligibility.
Born in the mid 60’s, [Tom Sachs] has always been fascinated with space, especially the Apollo program. Just like every kid of his generation, [Tom] imagined himself in Neil Armstrong’s and Buzz Aldrin’s boots, gazing over the lunar surface. He never gave up that dream, and years later as a successful modern artist, he built his own space program.
[Tom Sachs] is a master of bricolage . Taken from the French word for tinkering, Wikipedia defines bricolage as “… the construction or creation of a work from a diverse range of things that happen to be available, or a work created by such a process.” The term could also describe the junkbox procurement methods we use on many of our own projects.
Both [Tom’s] 2007 lunar program and his 2012 Mars program featured his astonishing lunar lander. Built from plywood, found items, and junk, the lander literally made us do a double take the first time we saw it. The attention to detail is incredible. At first glance one could mistake this for a simulator built by NASA themselves. After a few seconds the custom touches start to jump out, such as a “Thank You” garbage door from a fast food restaurant, or a bar stocked with tequila and vodka. The lander’s tools are not just for show either, as the gallery opens with a simulated space mission, which could best be described as a mix of art, improv, and an epic game of make-believe for adults.
[Tom’s] installations also include mission control, which in his Mars piece consisted of a dizzying array of screens, controls and an 80’s boombox. Dressed in the white shirt, thin tie, and horn rimmed glasses we’ve come to associate with NASA engineers of the 60’s, this is where [Tom] works. He truly is the engineer of this mission.
Editor’s Note [Tom] and the entire hacker community at large have a chance to go to space by entering The Hackaday Prize!

Have you ever wanted to build a robot arm, or even a full robot, but were put off by the daunting task of making all of those articulations work? Moti could make that a lot easier. The project seeks to produce smart servo motors which can connect and communicate in many different ways. It’s a great idea, so we wanted to know more about the hacker behind the project. After the jump you’ll find [nsted’s] answers to our slate of question for this week’s Hacker Bio.

Thanks to [Edward Snowden] we have a huge, publicly available catalog of the very, very interesting electronic eavesdropping tools the NSA uses. Everything from incredibly complex ARM/FPGA/Flash modules smaller than a penny to machines that can install backdoors in Windows systems from a distance of eight miles are available to the nation’s spooks, and now, the sufficiently equipped electronic hobbyist can build their own.
[GBPPR2] has been going through the NSA’s ANT catalog in recent months, building some of the simpler radio-based bugs. The bug linked to above goes by the codename LOUDAUTO, and it’s a relatively simple (and cheap) radar retro-reflector that allows anyone with the hardware to illuminate a simple circuit to get audio back.
Also on [GBPPR2]’s build list is RAGEMASTER, a device that fits inside a VGA cable and allows a single VGA color channel to be viewed remotely.
The basic principle behind both of these bugs is retroreflection, described by the NSA as a PHOTOANGLO device. The basic principle behind these devices is a FET in the bug, with an antenna connected to the drain. The PHOTOANGLO illuminates this antenna and the PWM signal sent to the gate of the FET modulates the returned signal. A bit of software defined radio on the receiving end, and you have your very own personal security administration.
It’s all very cool stuff, but there are some entries in the NSA catalog that don’t deal with radio at all. One device, IRATEMONK, installs a backdoor in hard drive controller chips. Interestingly, Hackaday favorite and current Hackaday Prize judge [Sprite_TM] did something extremely similar, only without, you know, being really sketchy about it.
While we don’t like the idea of anyone actually using these devices, the NSA ANT catalog is still fertile ground for project ideas.
