Seems like all the buzz about autonomous vehicles these days centers around self-driving cars. Hands-free transportation certainly has its appeal – being able to whistle up a ride with a smartphone app and converting commute time to Netflix binge time is an alluring idea. But is autonomous personal transportation really the killer app that everyone seems to think it is? Wouldn’t we get more bang for the buck by automating something a little more mundane and a lot more important? What about automating the shipping of freight?
Look around the next time you’re not being driven to work by a robot and you’re sure to notice a heck of a lot of trucks on the road. From small panel trucks making local deliveries to long-haul tractor trailers working cross-country routes, the roads are lousy with trucks. And behind the wheel of each truck is a human driver (or two, in the case of team-driven long-haul rigs). The drivers are the weak point in this system, and the big reason I think self-driving trucks will be commonplace long before we see massive market penetration of self-driving cars.

How often do you see problems that need fixing? How often do you design your own solutions to them — even if they won’t be implemented at scale? Seeing that many of the municipal parking lots in his native Sri Lanka use a paper ticketing system which is prone to failure, [Shazin Sadakath] whipped up his own solution: an efficient RFID tag logging system.

There are one or two perennial scientific stories that sound just too good to be true, but if they delivered on their promise would represent a huge breakthrough and instantly obsolete entire fields. One example is so-called “cold fusion”, the idea that nuclear fusion could be sustained with a net energy release at room temperature rather than super-high temperature akin to that of the sun. We all wish it could work, but so far it has obstinately refused. As a TV actor portraying a space engineer of the future once said, one “cannae change the Laws of Physics“.

What’s the most un-intrusive GPS you’ve ever seen? How about for a bike? Redditor [Fyodel] has built a Teensy-based GPS/GSM tracker that slides into your bike’s handlebars and really is out of sight.
The tracker operates on T-Mobile’s 2G service band — which will enable the device to work until about 2020 — since AT/T is phasing out their service come January. Since each positioning message averages 60 bytes, an IoT data plan is sufficient for moderate usage, with plans to switch over to a narrow-band LTE service when it becomes more affordable. [Fyodel] admits that battery life isn’t ideal at the moment, but plans to make it more efficient by using a motion sensor to ensure it’s only on when it needs to be.

It’s taken as canon that girls mature faster than boys. In reality, what happens is that boys stop maturing at about age 12 while girls keep going. And nothing tickles the fancy of the ageless pre-teen boy trapped within all men more than a good fart joke. To wit, we present a geolocating fart tracker for your daily commute.
[Michel] is the hero this world needs, and although he seems to have somewhat of a preoccupation with hacks involving combustible gasses, his other non-methane related projects have graced our pages before, like this electrical meter snooper or an IoT lawn mower. The current effort, though, is a bit on the cheekier side.
The goal is to keep track of his emissions while driving, so with a PIC, an ESP8266, a GPS module, and a small LCD display and keyboard, he now has a way to log his rolling flatulence. When the urge overcomes him he simply presses a button, which logs his location and speed and allows him to make certain qualitative notes regarding the event. The data gets uploaded to the cloud every Friday, which apparently allows [Michel] to while away his weekends mapping his results.
It turns out that he mainly farts while heading south, and he’s worried about the implications both in terms of polar ice cap loss and how Santa is going to treat him next month. We’re thinking he’s got a lock on coal — or at least activated charcoal.
Our beef with this project is obvious – it relies on the honor system for input. We really need to see this reworked with an in-seat methane detector to keep [Michel] honest. Until then, stay young, [Michel].
Our hats off to [SpeedyCop] and his [Gang of Outlaws] for turning a junked former Vietnam War helicopter into both an amphibious vehicle and a road race car. Yes, that’s right. It’s both driven on water and raced in the 24 Hours of LeMons at New Jersey Motorsports Park.
It started life as a 1969 Bell OH-58 Kiowa (US Army Vietnam Assault helo) and had not only served in Vietnam but also for a federal drug task force. It was chopped up for parts and the body found its way to [SpeedyCop] and friends. The body now sits on an 80s Toyota van chassis, has a Mazda Miata rear suspension, and Audi 3.0 V6 engine.
The pontoons were originally added to hide the seam between the helicopter body and the van but they then inspired the idea of making it amphibious. And with the addition of a four-blade, 7000 RPM propeller from a parasail boat, the idea became reality, as you can see in the video after the break (we suspect the trailing line is a rope to pull it back to shore in case of engine failure).

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.
