Where do you travel every day? Are there any subtle ploys to manipulate your behavior? Would you recognize them or are they just part of the location? Social engineering sometimes gets a bad rap (or is it rep?) in the mainstream, but the public-facing edge of that sword can keep order as it does in Japanese train stations. They employ a whirlwind of psychological methods to make the stations run like clockwork.
The scope of strategies ranges from the diabolical placement of speakers emitting high-frequency tones to discourage youthful loitering to the considerate installation of blue lights to deter suicides. Not every tactic is as enlightened as suicide prevention, sometimes, just changing the grating departure buzzer to a unique tune for each station goes a long way to relieving anxiety. Who wants to stand next to an anxious traveler who is just getting more and more sweaty? Listen below the break to hear what Tokyo subway tunes sound like.
Maybe you can spot some of these tricks where you live or something similar can ease your own commute. Perhaps the nearest subway has a piano for stairs or a 3D printing cyborg.

They say necessity is the mother of invention. But if the thing you need has already been invented but is extremely expensive, another mother of invention might be budget overruns. That was the case when [klinstifen]’s local government decided to put in countdown clocks at bus stops, at a whopping $25,000 per clock. Thinking that was a little extreme, he decided to build his own with a much smaller price tag.
The project uses a Raspberry Pi Zero W as its core, and a 16×32 RGB LED matrix for a display. Some of the work is done already, since the bus system has an API that is readily available for use. The Pi receives the information about bus schedules through this API and, based on its location, is able to determine the next bus arrival time and display it on the LED matrix. With the custom 3D printed enclosure and all of the other material, the cost of each clock is only $100, more than two orders of magnitude less expensive.
Hopefully the local government takes a hint from [klinstifen] and decides to use a more sane solution. In the meantime, you might be able to build your own mass transit clock that you can use inside your own house, rather than at the train station, if you’re someone who has a hard time getting to the bus stop on time.

New York City’s L train carries about 400,000 passengers a day, linking Manhattan and Brooklyn and bringing passengers along 14th Street, under the East River, and through the neighborhoods of Williamsburg, Bushwick, Ridgewood, Brownsville, and Canarsie. About 225,000 of these passengers pass through the Canarsie Tunnel, a two-tube cast iron rail tunnel built below the East River between Manhattan and Brooklyn in 1924. Like many other New York City road and subway tunnels, the Canarsie Tunnel was badly damaged when Hurricane Sandy’s storm surge inundated the tubes with million of gallons of salt water. Six years later, the impending closure of the tunnel is motivating New Yorkers to develop their own ambitious infrastructure ideas.

The fatal combination of not being a early riser and commuting to work using public transit can easily result in missed buses or trains. Frustrated with missing train after train while fumbling with a complicated transit schedule app, [Fergal Carroll] created a Train Time Ticker to help his morning routine run right on time.
A Particle Photon hooked up to a 2.2″ TFT screen — both mounted on a breadboard with a button — fit the purpose tidily. Weekday mornings, the Ticker pulls — from a server he set up — the departure times for the specific station and platform along [Carroll]’s commute every three minutes; at all other times, the Ticker can be manually refreshed for any impending trips.

A lot of us take roads for granted, at least until they are icy or torn up by construction. The concept of creating fixed paths seems to be in our firmware. Finding the shortest distance to food or water and marking a trail to it from home base has always been its own reward.
Roads have come a long way from the simple paths beaten by man and beast. But the basic configuration of paved roads hasn’t changed all that much since the Roman empire. Whatever they’re made of, they need to be able to drain water and support heavy loads.
New issues arose as modes of transportation shifted in favor of the automobile. Road surfaces needed to provide friction against tires. But how did we get from the stone-paved roads of Rome to the asphalt and concrete roads of today?

Do you have a spare mobility scooter sitting unused in your garage? Or, maybe you’ve got a grandmother who has been complaining about how long it takes her to get to bingo on Tuesdays? Has your local supermarket hired you to improve grocery shopping efficiency between 10am and 2pm? If you answered “yes” to any of those questions, then the guys over at Photon Induction have an “overclocked” mobility scooter build which should provide you with both inspiration and laughs.
They’ve taken the kind of inexpensive mobility scooter that can be found on Craigslist for a couple hundred dollars, and increased the battery output voltage to simultaneously improve performance and reduce safety. Their particular scooter normally runs on 24V, and all they had to do to drastically increase the driving speed was move that up to 60V (72V ended up burning up the motors).
Other than increasing the battery output voltage, only a couple of other small hacks were necessary to finish the build. Normally, the scooter uses a clutch to provide a gentle start. However, the clutch wasn’t up to the task of handling 60V, so the ignition switch was modified to fully engage the clutch before power is applied. The horn button was then used as the accelerator, which simply engages a solenoid with massive contacts that can handle 60V. The result is a scooter that is bound to terrify your grandmother, but which will get her to bingo in record time.
