Security Engineering: Inside the Scooter Startups

Posted on by

A year ago, ridesharing scooter startups were gearing up for launch. Workers at Bird, Lime, Skip, and Spin were busy improving their app, retrofitting scooters, and most importantly, figuring out the logistics of distributing thousands of electronic scooters along the sidewalks of the Bay Area. These companies were gearing up for a launch in early summer, but one company — nobody can remember exactly who — decided to launch early. First mover advantage, and all. Overnight, these scooter companies burst into overdrive, chucking scooters out of panel vans onto the sidewalk simply to keep up with the competition.

The thing …read more

Hacking the humble Roadster Bicycle

Posted on by

Think of bicycles, and your first mental image could be something pretty fancy. Depending on which side of the sport you favor, you could end up thinking of a road bike or an MTB, maybe DH, CX, BMX, TT, tandem or recumbent.

But for people in most parts of the World such as Asia, Africa and South America, the bicycle conjures up a very different image – that of the humble roadster. And this simple, hardy machine has spawned innumerable hacks to extend its usefulness and functionality by enterprising people with limited means. For them, it is not as much …read more

Digital License Plates Are Here, But Do We Need Them?

Posted on by

It’s a story as old as time: you need to swap between your custom license plates, but you can’t find a screwdriver and you’re already running late for a big meeting at the Business Factory. You called AAA to see if they could come out and do it for you, but as luck would have it something must be wrong with your phone because the line was disconnected as soon as you explained the situation. As if life in the First World couldn’t get any more difficult.

Luckily, a company called Reviver Auto has come up with a thoroughly modern …read more

Shred The Gnar Without Paddling For Waves

Posted on by

[Ben Gravy] isn’t your average pro surfer. For one thing, he lives in New Jersey instead of someplace like Hawaii or Australia, and for another he became famous not for riding the largest waves but rather for riding the weirdest ones. He’s a novelty wave hunter, but some days even the obscure surf spots aren’t breaking. For that, he decided to build a surfboard that doesn’t need waves.

The surfboard that [Ben] used for this project isn’t typical either. It’s made out of foam without any fiberglass, which makes the board less expensive than a traditional surfboard. The propulsion was …read more

This Beer Keg Is A Side Car

Posted on by

Bikes are a great way to get around. They’re cheap compared to cars and can be faster through city traffic, and you can get some exercise at the same time. The one downside to them is that the storage capacity is often extremely limited. Your choices are various bags strapped to the bike (or yourself), a trailer, or perhaps this bicycle side car made from a beer keg.

Sidecars are traditionally the realm of motorcycles, not bicycles, but this particular bike isn’t without a few tricks. It has an electric motor to help assist the rider when pedaling. With this …read more

Buy Your Very Own Commercial Flight Simulator

Posted on by

If you happen to live near Phoenix, Arizona, have a spare US$10,000 or so kicking around, and have always fancied your own true-to-life commercial flight simulator, today is your lucky day. With just over a week to go on the auction, you can bid on a used flight simulator for a Bombardier CRJ200 regional jet airliner.

The CRJ200 jet was produced between 1991 and 2006, first being introduced in 1992 by Lufthansa. It’s a twin-engine design, with about 50 seats for passengers. With a length of more than 26 meters, 12,500 km (41000ft) ceiling, 785 km/h (487mph) cruising speed and …read more

Scramjet Engines on the Long Road to Mach 5

Posted on by

When Charles “Chuck” Yeager reached a speed of Mach 1.06 while flying the Bell X-1 Glamorous Glennis in 1947, he became the first man to fly faster than the speed of sound in controlled level flight. Specifying that he reached supersonic speed “in controlled level flight” might seem superfluous, but it’s actually a very important distinction. There had been several unconfirmed claims that aircraft had hit or even exceeded Mach 1 during the Second World War, but it had always been during a steep dive and generally resulted in the loss of the aircraft and its pilot. Yeager’s accomplishment wasn’t …read more

Low Tech High Safety and the NYC Subway System

Posted on by

The year is 1894. You are designing a train system for a large city. Your boss informs you that the mayor’s office wants assurances that trains can’t have wrecks. The system will start small, but it is going to get big and complex over time with tracks crossing and switching. Remember, it is 1894, so computing and wireless tech are barely science fiction at this point. The answer — at least for the New York City subway system — is a clever system of signals and interlocks that make great use of the technology of the day. Bernard S. Greenberg …read more

Electrifying A Vintage Outboard Motor

Posted on by

Clamped or bolted to the stern of the boat, outboard motors offer a very easy and (relatively) economical way of powering small craft. The vast majority of these outboards are gasoline powered, with electric models generally limited to so-called “trolling motors” which are often used to move slowly and quietly during fishing. That might be fine for most people, but not [Olly Epsom].

An engineer focusing on renewable energy by profession, [Olly] wanted to equip his small inflatable dinghy with a suitably powerful “green” propulsion system. Deciding nothing on the market quite met his requirements, especially for what manufacturers were …read more

A Quartet of Drills Put The Spurs To This Electric Utility Vehicle

Posted on by

Low-slung body style. Four-wheel drive. All electric drivetrain. Turns on a dime. Neck-snapping acceleration. Leather seating surface. Is it the latest offering from Tesla? Nope; it’s a drill-powered electric utility vehicle, and it looks like a blast to drive.

Surprisingly, this isn’t a just-for-kicks kind of build. There’s actually a practical reason for the low form factor and long range of [Axel Borg]’s little vehicle. We’ll leave the back story to the second video below, but suffice it to say that this will be a smaller version of the crawler NASA used to roll rockets out to the launch pad, …read more
