Furter Burner Cooks The Wieners Just So

Sometimes you’re hungry for two sausages, and not a sausage more. [Wesley] designed his Furter Burner to handle precisely these situations, and it looks to cook up a pair of wieners a treat. (Video, embedded below.)

The process starts with a couple of wooden stunt wieners, and some foam board, with which [Wesley] roughs out a design. From there, a CAD design is drawn up and parts routed out of compressed board to troubleshoot the assembly further. Later moving on to a plywood version, having a wooden prototype quickly reveals plenty of things to improve, from adding handles to the grill surface to air holes to allow combustion.

The design goes through a couple of further iterations in metal before completion. The final result is impressive—resulting in a twin-wiener cooker that burns coals, complete with skewers for easy sausage handling and bearing [Wesley’s] own logo.

The video shows off the benefits of the iterative design process. It also demonstrates why it often makes sense to rough out designs in cheaper materials before going to the heavy stuff, particularly in a case like [Wesley]’s where the metal parts can only be cut off-site. Refining the design in-house first saves a lot of mucking around.

We’ve seen [Wesley]’s work before, too – like this impressive workshop storage solution.

3D Printering: Corrugated Plastic For Cheaper & Easier Enclosures

Clear acrylic panels have long been a mainstay of 3D printer enclosure designs, but they can also add significant cost in terms of money, shipping, weight, and hassle. An alternative material worth looking at is corrugated plastic (also known by its trade name coroplast) which is cheap, light, an excellent insulator, and easy to work with. Many enclosure designs can be refitted to use it instead of acrylic, so let’s take a closer look at what it has to offer.

What’s Wrong With Acrylic?

It’s not just the purchase price that makes acrylic a spendy option. Acrylic is fairly heavy, and shipping pieces the size of enclosure panels can be expensive. Also, cutting acrylic without special tools can be a challenge because it cracks easily if mishandled. Acrylic cuts beautifully in a laser cutter, but most laser cutters accessible to a hobbyist are not big enough to make enclosure-sized panels. If you are stuck with needing to cut acrylic by hand, here are some tips on how to get by with the tools you have.

It is best to source acrylic from a local shop that can also cut it to size with the right tools for a reasonable price, but it is still far from being a cheap material. There’s another option: corrugated plastic has quite a few properties that make it worth considering, especially for a hobbyist.

Building A Multi-Ton Power Loader For Fun

Exoskeletons, power suits, and iron suits in science fiction have served as the inspiration for many engineers and engineering projects over the years. This is certainly the case at [Hacksmith Industries], where Hackaday alum [James Hobson] has been building a massive mechanical exoskeleton since January 2019, inspired by the P-5000 Power Loader from the Alien movies. (Video, embedded below.)

Unlike the movie version, the [Hacksmith] power loader is not bipedal but built on top of the chassis of a small tracked skid-steer loader. Its existing hydraulic power unit also feeds all the upper body hydraulic cylinders. The upper body maintains the basic look of the movie version and was built from plasma-cut steel sections that fit together with a tab and slot system before being welded. Each arm has five degrees of freedom, controlled by proportional hydraulic valves. The power loader is controlled by an industrial grade control system based on the Raspberry Pi, running ROS.

Every single actuator is capable of applying enough force to kill, so safety is an important consideration in the design. It has emergency stop buttons mounted in several locations, including on a wireless remote. The ROS controller monitors the position of every cylinder using string potentiometers for closed-loop control, and to trigger the emergency stop if an actuator goes out of bounds. The power loader can be controlled by the onboard pilot using a pair of simulator flight controller joysticks, or remotely using a PS4 controller.

[Hacksmith Industries] is clear about the fact that they are building multi-ton power loaded for fun and entertainment, not because it’s necessarily practical or a commercially viable product. However, other exoskeletons have proven that they are a viable solution for reducing fatigue and risk of injury for industrial workers, and carrying heavy loads in rough terrain.

An Atari ST running a campground reservation system

Atari ST Still Manages Campground Reservations After 36 Years

“Don’t fix it if it ain’t broke”. That’s what we guess [Frans Bos] has been thinking for the past few decades, as he kept using his Atari ST to run a booking system for the family campground. (Video, embedded below.)

Although its case has yellowed a bit, the trusty old machine is still running 24/7 from April to October, as it has done every year since 1985. In the video [Frans] demonstrates the computer and its custom campground booking system to [Victor Bart].

To be exact, we’re looking at an Atari 1040STF, which runs on a 68000 CPU and has one full megabyte of RAM: in fact it was one of the first affordable machines with that much memory. Output is through a monochrome display, which is tiny compared to the modern TFT standing next to it, but was apparently much better than the monitor included with a typical DOS machine back in the day.

Since no campground management software was available when he bought the computer, [Frans] wrote his own, complete with a graphical map showing the location of each campsite. Reservations can be made, modified and printed with just a few keystrokes. The only concession to the modern world is the addition of a USB drive; we can imagine it was becoming difficult to store and exchange data using floppy disks in 2021.

We love seeing ancient hardware being actively used in the modern world: whether it’s floppy disks inside a Boeing 747 or an Amiga running a school’s HVAC system. Thanks to [Tinkerer] for the tip.
