Train Time Ticker Will Save Your Morning Commute

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.

Sensor rig finds out if motorists are sharing the road with cyclists

Apparently there’s some cause for concern when it comes to bikes and automobiles sharing the roads in Austin, Texas. [Christopher Stanton] wrote in to tell us there’s a law on the books now that requires motorists to give three feet of space when passing a cyclist. This is pretty difficult to enforce as there’s no solid proof like the radar gun provides when it comes to speed limits. The hardware above is seeking to help by collecting data on passing habits. It measures and records the distance of each vehicle that passes you while on the bike. The goal isn’t to ticket more drivers, it’s to collect statistical data that might help change dangerous driving habits.

As you can see, a front equipment rack hosts the hardware for easy installation on a bike. It has an arm that extends to the side the same distance as the handle bars. The HD camera with wide-angle lens is set to snap a photo which can be used to determine the bike and vehicle positions in the lanes, along with the distance readout from the sensor.

We’d certainly be interested in seeing the numbers for average passing clearance in a heavily traveled urban environment. Even with bike lanes, things can feel pretty tight on a busy day!

The subway never sounded so good

Reader [Philippe] tipped us off about this video showing a set of subway steps being turned into a piano keyboard (english translation). The creators wanted to make taking the stairs rather than riding the escalator a bit more fun. They added pressure sensors to each step, then covered them with white and black keys to resemble a keyboard. When a passenger puts their weight on a step, the corresponding pitch is played out loud.

We may have lied in the title as this doesn’t really compare to hearing Josh Bell play for pocket change at your train stop. But coming across this setup on an otherwise mundane commute would really brighten up our day.
