These days, we’re blessed with wired and wireless networks that can carry huge amounts of data in the blink of an eye. However, some areas are underprovisioned with bandwidth, such as Schmallenberg-Oberkirchen in Germany. There, reporters ran a test last December to see which would be faster: the Internet, or a horse?
The long and the short of it is that Germany faces issues with disparate Internet speeds across the country. Some areas are well-served by high-speed fiber services. However, others deemed less important by the free market struggle on with ancient copper phone lines and subsequently, experience lower speeds.
Thus, the experiment kicked off from the house of photographer [Klaus-Peter Kappest], who started an Internet transfer of 4.5GB of photos over the Internet. At the same time, a DVD was handed to messengers riding on horseback to the destination 10 kilometers away. The horses won the day, making the journey in about an hour, while the transfer over [Kappest’s] copper connection was still crawling along, only 61% complete.
Obviously, it’s a test that can be gamed quite easily. The Internet connection would have easily won over a greater distance, of course. Similarly, we’ve all heard the quote from [Andrew Tanenbaum]: “Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.”
Notably, [Kappest’s] home actually had a fiber line sitting in the basement, but bureaucracy had stymied any attempts of his to get it connected. The stunt thus also served as a great way to draw attention to his plight, and that of others in Germany suffering with similar issues in this digital age.
Top speeds for data transfer continue to rise; an Australian research team set a record last year of 44.2 terabits per second. Naturally, the hard part is getting that technology rolled out across a country. Sound off below with the problems you’ve faced getting a solid connection to your home or office.
Oh [Rodger Cleye]! You had us at “unicycle, duct tape, styrofoam, and tie wraps”. But watching the horse-bike in action (video below) is just about enough for us to go out and make one ourselves. (For our child, naturally. We’re far too dignified.)
If you trawl around [Rodger]’s YouTube channel, you’ll see no end of odd motorized vehicles. Like last year’s motorized horse project, or this stormtrooper speeder. But there’s just something about the way that the horse’s legs move along with the rider that is slightly more enchanting. (That’s the “unicycle” part of the build.) And, we assume, the rider gets a little bit more exercise to boot.
We’ve featured a few builds of [Rodger]’s before, including his motorized couch build that’s obviously controlled from the seat-mounted coconut, and of course a pneumatic Boba Fett rocket.
[Lvl_joe] has been having a little fun with fire and an animatronic pony. The skeletal horse seen above is a child’s toy denuded of its original plush shell. That’s a good thing, because those synthetic fibers don’t play very nicely with flames. The toy originally retailed for around $300 bucks, but if you’re lucky, like [Joe], you can get one second-hand for $25 or less.
Since the horse is already motorized, it’s not too hard to patch into the drivers. Here an Arduino is used to take input from a Wii Nunchuck, letting you swing the fire sprayer to and fro. A grill igniter makes sure it’s not just spraying automotive starter fluid everywhere. You can hear the click of that tiny spark repeatedly firing in the demo video after the break. The starter fluid comes in an aerosol can. A custom trigger system holds the can in a PVC pipe, and actuates the valve with a Bowden cable.

[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance between the two pieces of copper changes, a measurement that is fairly easy to make with an analog to digital converter. The mat is being used to measure how well a horse saddle fits the animal. Data is read in through a serial port and then mapped using Excel. This prototype proves that the concept works but [imsolidstate] mentions that there’s room to improve the sensitivity and that there could be more noise filtering incorporated into the design.
