The ocean is a hostile environment for man-made equipment, no matter its purpose. Whether commercial fishing, scientific research, or military operations, salt water is constantly working to break them all down. The ocean is also home to organisms well-adapted to their environment so DARPA is curious if we can leverage their innate ability to survive. The Persistent Aquatic Living Sensors (yes, our ocean PALS) program is asking for creative ideas on how to use sea life to monitor ocean activity.
Its basic idea is simple: everyday business of life in the ocean are occasionally interrupted by a ship, a submarine, or some other human activity. If this interruption can be inferred from sea life response, getting that data could be much less expensive than building sensors to monitor such activity directly. Everyone who applies to this research program will have the chance to present their own ideas on how to turn this idea into reality.
The program announced it will “study natural and modified organisms” (emphasis ours.) Keeping an open mind to bio-engineering ideas will be interesting, but adding biohacking to the equation also adds to the list of potential problems. While PALS will keep its research within contained facilities, any future military deployment obviously will not. Successful developments in this area will certainly raise eyebrows and face resistance against moving beyond the lab.
But such possibilities are still far away in a future that many never arrive, as is common with DARPA initiatives. Very recently we talked about their interest in brain stimulation and we’ve been fascinated by many DARPA initiatives before that. If PALS takes off, their living sensor nodes might end up face to face with the open-source underwater glider project that won this year’s Hackaday prize.
Boeing and DARPA are building a spaceplane. Right now it’s only a press release and a few concept images, but it looks like this is an air-launched system kind of like a Tristar/Pegasus, only much higher and completely unmanned. It’s a ton and a half to low earth orbit, with a goal of 10 flights in 10 days.
Up in Albany? There’s a new hacker con happening in a few weeks. Anycon is a hacking, infosec, and cyber security conference happening June 16 & 17th in Albany, NY. The organizers of this con ([Chris], and his company Leet Cybersecurity) are loosely modeling this con after Derbycon. [Dave Kennedy] of TrustedSec will be attending as the keynote speaker.
GOOD NEWS! [Casey Neistat] is under investigation by the FAA. [Casey Neistat] is the YouTuber that flies drones right in the middle of the Hudson River corridor, and is a menace to general aviation around NYC.
This is neat. The Supplyframe Design Lab is the Hackaday Mothership right in the middle of Pasadena where we host our designers in residence, host a few meetups, and slowly fill every cubic inch of space with either dust or tools. The Design Lab just won a design award. You can check out the ‘design’ part of the Design Lab here, but keep in mind it will never be that clean ever again.
Here’s an interesting Twitter to follow. Alitronik is a curator of the weird and wonderful cheap crap that can be found on AliExpress. Need an Altera Cyclone dev board? Here you go. A desk-mountable OLED inspection microscope? Done. A seven dollar Tesla coil? Dude, you can totally fit this inside a hat.
[Drygol] had a nice old Commodore C16 with a broken TED chip. A shame, really. He did what anyone would do: put a C64 motherboard in the case for a fancy stealth upgrade.
Is the great crowdfunded 3D printer boom over? Some would say that ship sailed after dozens of 3D printer crowdfunding projects failed to deliver, or delivered very low-quality machines. These people were wrong. This Polaroid-branded 3D printing pen might not get funding. A year ago, this project would have been funded on day one. There would have been writeups in The Verge on how Polaroid is turning the corner after decades of wasted opportunities. Now, the Crowdfunded 3D printer boom is finally over.
The Hackaday crew was at the Bay Area Maker Faire last weekend and holy crap did we have a blast. Everyone came to the meetup on Saturday except for the fire marshall. The secret OSHPark bringahack on Sunday was even more impressive. We also saw a Donkey Car capable of driving around a track autonomously, but the team behind it didn’t have their work up on the Internet at the time.
So [DARPA] wants to start hacking human brains, With the help of the biomedical device center at the university of Texas in Dallas. This does sound a bit crazy but DARPA does crazy. Conspiracy theorists are going to have a field day with this one.
The initial plans to turn us all into mindless zombies seem to be shelved for now, however they are working on what they call Targeted Neuroplasticity Training (TNT), which they explain means using the body’s nervous system to enhance and speed up the learning process. This could be achieved by using a process known as ‘synaptic plasticity‘ which opens and closes the brains synapses with electrical stimulation. They hope that by tuning the neural networks responsible for cognitive function it will enhance learning. Let’s just hope they don’t turn any humans into DARPA falling robots.
If you are like most people, your drone flights start on the ground and end either on the ground or–in more cases than most of us want to admit–in a tree. Earlier this year, DARPA awarded initial contracts for the Gremlins program. The idea is to produce unmanned aircraft that can launch from another aircraft and then later have another aircraft recover it.
The idea is to allow a plane to launch an unmanned sensor, for example, while out of range of enemy fire. Later another aircraft can retrieve the drone where a ground crew would get it ready for another flight within 24 hours. An aircraft facing missile fire could unleash a swarm of drones, confusing attackers. The drones have a limited life of about twenty flights, allowing for inexpensive airframes that use existing technology. You can see a concept video from DARPA about how air-launched drones might play a role in future air combat below.

Aviation Week and Space Technology, the industry’s leading magazine, has been publishing “pilot reports,” on new aircraft for decades. Its pilot report on an aircraft called Centaur was the first in which the pilot doing the test never touched the controls. Centaur is an optionally-piloted aircraft, or OPA.
The reporter conducted the test while sitting in the back seat of the small, twin engine aircraft. Up front sat a person acting as the safety pilot, his arms calmly resting on his lap. Sitting beside him, in what is ordinarily the co-pilot’s seat, was an engineered series of linkages, actuators, and servos. The safety pilot pulled a lever to engage the mechanisms, and they began moving the pilot’s control stick and pressing the rudder pedals. The actuators are double and redundant; if one set fails another will immediately take over. The safety pilot can disengage the mechanism with a single pull of the lever if something goes wrong; unless something goes wrong he does not touch the controls.
In the back seat, the “operator,” commanded the plane through a laptop, using an interface identical to that of the ground control station for an unmanned vehicle. Through the screen, he could change altitude, fly to waypoints, takeoff or land. Pushing the “launch” button began an autonomous takeoff. The computer held the brakes, pushed the throttles forward, checked the engines and instruments, and released the brakes for the takeoff roll. The plane accelerated, took to the air, and began to climb out on a semi-autonomous flight.

Researchers over at MIT are hard at work upgrading their Robotic Cheetah. They are developing an algorithm for bounding movement, after researching how real cheetahs run in the wild.
Mach 2 is fully electric and battery-powered, can currently run at speeds of 10MPH (however they’re predicting it will be able to reach 30MPH in the future), and can even jump over obstacles 33cm tall.
We originally saw the first robotic Cheetah from Boston Dynamics in cooperation with DARPA two years ago — it could run faster than any human alive (28.3MPH) but in its tests it was tethered to its hydraulic power pack and running on a treadmill. It’s unclear if MIT’s Cheetah is a direct descendant from that one, but they are both supported by DARPA.
The technology in this project is nothing short of amazing — its electric motors are actually a custom part designed by one of the professors of Electrical Engineering at MIT, [Jeffrey Lang]. In order for the robot to run smoothly, its bounding algorithm is sending commands to each leg to exert a very precise amount of force during each footstep, just to ensure it maintains the set speed.

Well, kind of. This is one of [Jason Kerestes’] latest projects as a masters engineering student at the Arizona State University — A jet pack designed to increase your running speed by quite literally giving you a boost.
It’s one of the proposed solutions to the 4MM (4 Minute Mile) project, which is part of the ASU Program called iProjects, which brings students and industry together to solve problems. The 4MM project is trying to find a way to make any soldier able to run the 4 minute mile — quite ambitious, but DARPA is actually working on it with [Jason]!
The whole rig only weighs 13lbs and features two electric turbines which provide the thrust. They originally tested the concept by seeing if you could pull a person with an electric golf cart around a track to make them run faster — turns out, you can. Further more scientific testing led them to find that there is a specific thrust to body-weight ratio that works best, with the direction of thrust about 25 degrees below horizontal.
