Hong Kong Hacker Builds Electric Vehicle From Waste

Recycled Parts Round Out Soap Shaped Electric Car

November 30, 2021 by Ryan Flowers 13 Comments

[Handy Geng] has a knack for fitting his creations with a large percentage of recycled material. And as is exemplified by the video below the break, he also loves to mix the practical with the whimsical.

Using parts salvaged from motor scooters, trash heaps, and likely many other sources, [Handy] has put together a small vehicle that he himself describes as looking like a bar of soap as it slips across the floor. You’ll agree when you see the independent front and rear steering at work, allowing the car’s front and rear to be driven and steered on their own. Crabbing sideways, driving diagonally, and we’re guessing spinning in place are possible.

What’s also clear in the video below is that [Handy] is a talented fabricator. While not taking himself too seriously (keep an eye out for the 360° selfie cam!) he clearly takes pride in the work. [Handy]’s workshop and skill set show that at the core, he’s quite serious about his craft. We appreciate the creative use of scrap materials used in such an inspiring build. The turn signals and “communicator” hand is absolutely marvelous.

If building with recycled materials is your thing, then you’ll love the Trash Printer, too. Thanks to [Fosselius] for the tip!

Being Green, It’s A Rich Man’s Game

October 26, 2021 by Jenny List 245 Comments

It’s an old saying with an apocryphal origin: “May you live in interesting times“. We Brits are certainly living in interesting times at the moment, as a perfect storm of the pandemic, rising energy prices, global supply chain issues, and arguably the post-Brexit departure of EU-national truck drivers has given us shortages of everything from fresh vegetables in the supermarket to carbon dioxide for the food industry. Of particular concern is a shortage of automotive fuels at the filling station, and amid sometimes-aggressive queues for the pumps it’s reported that there’s a record uptick in Brits searching online for information about electric cars.

Nothing Like A Crisis To Make You Green

My VW Polo loaded for EMF 2018 — How I miss my little car, here loaded for EMF 2018.

This sudden interest in lower-carbon motoring may be driven by the queues rather than a concern for the planet, but it’s certainly true that as a culture we should be making this move if we are to have a hope of reducing our CO2 production and meeting our climate goals. A whole slew of lifestyle changes will have to be made over the coming years of which our car choices are only a part. Back to those beleaguered Brits again, a series of environmental protests have caused major disruption on the motorway network round London, not protesting against the traffic but campaigning for better home insulation.

For reasons of personal circumstance rather than principle, earlier this year I gave my trusty VW Polo to an old-Volks-nut friend and now rely on a bicycle. Living where I do within reach of everything I need it hasn’t been as challenging as I expected it to be, and aside from saving a bit of cash I know my general fitness level has gone up. Though I have less need for a car now than I used to, I intend to find myself another vehicle in due course so that I can do silly things such as throwing a Hackaday village in the back and driving halfway across Europe to a hacker camp. With an awareness that whatever I choose should be as good for the planet as I can make it then, I’ve been cruising the used-car websites to see what I can find.

A Robot To Top Up Your Tesla

July 2, 2021 by Danie Conradie 37 Comments

The convenience of just plugging in your car in the evening and not going into a gas station is great as long as you remember to do the plugging. You really don’t want to get caught with an empty battery while you’re in a rush. [Pat Larson]’s Tesla plugging robot might be a handy insurance policy if you count forgetfulness among your weaknesses.

The robot consists of a standard Tesla charging plug attached to a 2-axis robotic arm mounted on [Pat]’s garage wall. Everything is controlled by a Python script running on Raspberry Pi 4. After taking a picture with a camera module, it uses a Tensor Flow Lite machine learning model to determine the position of a reflector on the charging port cover. The platform moves back and forth to align with the charging port, after which it opens the charging port using the Tesla API. It then extends the arm towards the charging port, using ultrasonic proximity sensors for distance control, and again uses the camera module and Tensor Flow to look for the illuminated Tesla logo adjacent to the charging port. The charge plug is flipped out using a large servo, and after some final position adjustment, it takes the plunge. While robot won’t be winning any interior design contests, it does the job well, and adds a bit of convenience and peace of mind.

Other Tesla hacks we’ve seen include building a working Model S for $6500, turning an old Honda into a speed demon using Tesla parts, and a Casio F-91W that can unlock your Tesla.

Electric Vehicles Could Be The Grid Storage Solution We’ve Been Dreaming Of

June 7, 2021 by Lewin Day 157 Comments

As nation states grapple with the spectre of environmental and economic losses due to climate change, we’ve seen an ever greater push towards renewable energy sources to replace heavier polluters like coal and natural gas. One key drawback of these sources has always been their intermittent availability, spurring interest in energy storage technologies that can operate at the grid level.

With the rise in distributed energy generation with options like home solar power, there’s been similar interest in the idea of distributed home battery storage. However, homeowners can be reluctant to make investments in expensive batteries that take years to pay themselves off in energy savings. But what if they had a giant battery already, just sitting outside in the driveway? Could electric vehicles become a useful source of grid power storage? As it turns out, Ford wants to make their electric trucks double as grid storage batteries for your home.

Magna Announces Simple Drive Solution For Electric Pickup Trucks

April 14, 2021 by Lewin Day 68 Comments

Thus far, the majority of electric cars on sale have been aimed at commuters, fitting into the sedan and SUV segments of the marketplace. Going forward, there’s a very real need for electrification to touch the whole spectrum of automobiles, and that includes work vehicles like pickup trucks. A company called Magna have recently thrown their hat into the ring in just this space, developing a simple drivetrain that can be readily installed in pickup trucks without major modifications.

Electric Vehicle 1900’s Style: New Leases On Old Tech

April 8, 2021 by Al Williams 69 Comments

Excited about your new electric vehicle? Thomas Edison would be, too. He tried to produce electric vehicles for Ford around 1900. Petroleum-based vehicles dashed his dreams of the electric car, and the battery he wanted to use languished as a technological dead end. The batteries were long-lasting, sure, but they were expensive and had other problems, not the least of which was producing hydrogen gas. But that battery technology is receiving renewed interest today, because some of the things that made it a bad car battery make it good for alternate energy projects.

You wouldn’t think a century-old battery technology that was never very popular would make a comeback. But then again, who thought we’d see the return of bell-bottom pants or vinyl records? Continue reading “Electric Vehicle 1900’s Style: New Leases On Old Tech” →

Sony’s Electric Car Now Road Testing In Austria

January 27, 2021 by Lewin Day 73 Comments

The Consumer Electronics Show was not typically a place for concept cars, and Sony aren’t known as a major automaker. However, times change, and the electric transport revolution has changed much. At the famous trade show, Sony shocked many by revealing its Vision-S concept — a running, driving, prototype electric car.

Far from a simple mockup to show off in-car entertainment or new fancy cameras, Sony’s entry into the automotive world is surprisingly complete. Recently, the Japanese tech giant has been spotted testing the vehicle on the road in Austria, raising questions about the future of the project. Let’s dive in to what Sony has shown off, and what it means for the potential of the Vision-S.
