Collaborate Disseminate
There’s a good chance you already saw SpaceX’s towering Starship prototype make its impressive twelve kilometer test flight. While the attempt ended with a spectacular fireball, it was still a phenomenal success as it demonstrated a number of concepts that to this point had never been attempted in the real …read more
For some people, mowing the lawn is a dreaded chore that leads to thoughts of pouring a concrete slab over the yard and painting it green. Others see it as the perfect occasion to spend a sunny afternoon outside. And then there are those without the luxury of having a …read more

Milrem Robotics and InnoVfoam have teamed up to create a new family of foam-shooting firefighting robots to help or replace human firefighters in dangerous situations. Based on Milrem’s Unmanned Ground Vehicle (UGV) Multiscope Rescue robot, the system … Continue reading New foam-shooting robots to keep firefighters out of harm’s way
For about as long as hackers and makers have been using desktop 3D printers, there have been critics that say the plastic parts they produce aren’t good for much else than toys and decorative pieces. They claim that printed parts are far too fragile to be of any practical use, …read more

Time is critical when rescuers are alerted to a swimmer in trouble, a surfer who’s taken a dive or a yacht guest who has fallen overboard. We’ve seen a number of crafty assistance devices over the years that are designed to help keep waterbab… Continue reading Remote-controlled lifebuoy propels itself to save troubled swimmers
We’ve all seen a movie or TV show that got our imagination going, and the more studious of us might get fired up over a good book (one without pictures, even). You never know were inspiration might come from, which is why it’s so hard to track down in the first place. But one place we don’t often hear about providing many hackers with project ideas is the grocery store. But of course the more we learn about [Michael Kohn], the more we realize he’s got a very unique vision.
On a recent trip to the grocery store, [Michael] saw …read more

Here’s something remarkably displeasant. Can you cook a steak with glue? [Dom] and [Chris] from ExplosiveDischarge have cooked a steak using a huge, huge amount of two-part epoxy. The chemistry behind this is just the exothermic reaction when two-part epoxy kicks off, and yes, the steak (a very thin cut) was sufficiently wrapped and protected from the hot sticky goo. What were the results? An overcooked steak, actually. This isn’t a sous vide setup where the temperature ramps up to 50°C and stays there — the temperature actually hit 80°C at its peak. There are a few ways to fix …read more
[Pen Test Partners] have found some really scary vulnerabilities in AGA range cookers. They are connected by SMS by which a mobile app sends an unauthenticated SMS to the AGA to give it commands for instance preheat the oven, You can also just tell your AGA to turn everything on at once.
The problem is with the web interface; it allows an attacker to check if a user’s cell phone is already registered, allowing for a slow but effective enumeration attack. Once the attacker finds a registered device, all they need to do is send an SMS, as messages are …read more

For anyone living in cooler climates, the annual onslaught of snow means many hours shoveling driveways and sidewalks. After a light snow, shoveling might seem a waste of time, while a snow blower would be overkill. If only there were a happy middle ground that required minimal effort; perhaps an RC snow groomer with a 3D printed snow blower would work.
We featured an earlier version of this project last year. This year’s model features a slipper clutch — combined with a differential from a heavy RC truck — to forestall damage to the attachment if you happen to hit …read more
Sometimes, a simple fix is the best solution. Lacking extra funds for a proper remote-controlled gate-opener after the recent purchase of their farm, redditor [amaurer3210] built one as a birthday gift for his wife.
Supported on pillow block housings, a 10″ wheel is connected to the motor by via a 3D printed pulley and a timing belt turned inside-out to allow for slippage — in case of obstacles or manual opening of the gate. If you’ve ever worked with belts in your builds, [amaurer3210] adds that during sizing he uses a few layers of fiberglass tape as a stand-in for …read more
