Vote Or Be Sorry — Round 2 Of Astronaut Or Not

b2

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.

 

[Tom Sachs] Builds His Own Space Program

sachslunarcapsuleinterior

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.

sachs-lunar-landerBoth [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!

THP Hacker Bio: Nsted

 

thp-contestant-bio-nsted

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.

Homebrew NSA Bugs

NSA

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.

Pi-Powered Anti-Cat Trap Soaks Felines And Other Animals

[Joshua] has a problem with cats. They like pooping in his garden. He decided to take action with this awesome automated and humane cat trap.

Now just to clarify, he did attempt a few other alternatives before going all out in cat defense – the easiest solution would be to get a cat of his own, but alas, he’s not a cat person.

The system uses a Raspberry Pi in a waterproofed housing with a PiCam. He’s written some rudimentary code to make use of the PiCam Python Library which also allows him to record pre-cat-trapping footage, much for our enjoyment. When motion is sensed, the Pi trips a 24VAC solenoid water valve, which turns on the sprinkler and quickly soaks the intruder.

Stick around after the break for quite a few videos catching the furry little buggers in the act!

A Simple Commodore 64 Cart Dumper

c64

While [Rob] was digging around in his garage one day, he ran across an old Commodore 64 cartridge. With no ROM to be found online, he started wondering what was stored in this ancient device. Taking a peek at the bits stored in this cartridge would require dumping the entire thing to a modern computer, and armed with an Arduino, he created a simple cart dumper, capable of reading standard 8k cartridges without issue.

The expansion port for the C64 has a lot of pins corresponding to the control logic inside these old computers, but the only ones [Rob] were really interested in were the eight data lines and the sixteen address lines. With a little bit of code, [Rob] got an Arduino Mega to step through all the address pins and read the corresponding data at that location in memory. This data is then sent over USB to a C app that dumps everything in HEX and text.

While the ROM for just about every C64 game can be found online, [Rob] was unlucky enough to find one that wasn’t. It doesn’t really matter, though, as we don’t know if [Rob] has the 1541 disk drive that makes this cart useful. Still, it’s a good reminder of how useful an Arduino can be when used as an electronic swiss army knife.

Upgraded Nerf Gun Keeps Track Of Your Ammo

[Paul] and his buddy [Jonathan] recently had a zombie themed Larp event to go to, so in the spirit of making the experience more realistic, they decided to upgrade their Nerf N-Strike Stryfe gun.

They started by cracking open the gun and making note of the available space for a few bells and whistles. Luckily, thanks to traditional plastic injection molding practices — there’s lots of room!

Upgrades include a magazine sensor, a jam sensor, a trigger sensor and a voltmeter to make the gun a little bit smarter. A knockoff Arduino Pro Mini takes in all these inputs and outputs it to a 7-segment LED display for easy visibility. Our favorite part is the ammo sensor, which keeps a tally of how many shots you’ve used. It’s simply an IR photo-diode and IR transistor in a Darlington configuration, connected to the GPIO interrupt pin on the fake Arduino.
