Cardboard Longboard Uses Quarter-Isogrid Structure

Skateboards are most typically crafted by hand, carved out of wood layered by care. However, many makers have sought to explore alternative techniques. [Technovation] decided to combine alternative materials and digital fabrication techniques to produce this attractive cardboard longboard.

The structure of the board was designed in Fusion 360, featuring …read more

Vacuum Molding with Kitchen Materials

Vacuum pumps are powerful tools because the atmospheric pressure on our planet’s surface is strong. That pressure is enough to crush evacuated vessels with impressive implosive force. At less extreme pressure differences, [hopsenrobsen] shows us how to cleverly use kitchen materials for vacuum molding fiberglass parts in a video can be seen after the break. The same technique will also work for carbon fiber molding.

We’ve seen these techniques used with commercially available vacuum bags and a wet/dry vac but in the video, we see how to make an ordinary trash bag into a container capable of forming a professional …read more

Printed Parts Make DIY Electric Longboard Possible

Appalled by expensive electric longboards, [Conor Patrick] still wanted one, and wanted it now. So — naturally — he converted an existing board into a sprightly electric version at a fraction of the cost.

[Patrick] is using a capable 380KV Propdrive motor, capable of pushing him up to 30mp/h! A waterproof 120A speed controller and 6000mAh, 22.2V LiPo battery slim enough to fit under the board give the motor the needed juice. He ended up buying the cheapest RF receiver and remote combo to control the board, but it fit the all-important “want electric long board now” criterion.

Initially, [Patrick] …read more

This Electric Longboard Collapses for Air Travel

How do you manage to get an electric off-road longboard past TSA and onto an international flight? Simple — make it a collapsible longboard that fits into a carry-on bag.

The mechanical and electrical feats accomplished by [transistor-man] may not be the most impressive parts of this hack. We’re pretty impressed by the build, starting as it did with the big knobby tires and front truck from an unused mountain board and the hub motor from a hoverboard, turning this into a trike. The incredible shrinking chassis comes courtesy of a couple of stout drawer slides and cam locks to …read more

Hackaday Prize Entry: An Electric Longboard

The Hackaday Prize is in full swing, and that means we’re starting to see all the builds a few select people have been saving up for the past few months. [yowhwui] has been working on a 3D printed electric longboard for a while now, and this build is really solid. He already has over 150km on the odometer, and the 3D printed parts are still holding up.

The power for this motor comes from a 6374 brushless motor running at 192 kV. This, plus two 4S 30C 5000mAh LiPo batteries propel this longboard to speeds up to 42 km/h (2.18 …read more

Another Electric Longboard Goes the Distance

Looks like electric longboards are becoming a thing, with increasingly complex electronics going into them to squeeze as much performance as possible out of them. When an electric longboard lasts for 35 miles, can longboard hypermiling be far behind?

If endurance longboarding sounds familiar, it’s because we just covered a 25-mile electric that outlasted its rider. To get the extra 10 miles, [Andrew] cheated a little, with a backpack full of extra batteries powering his modified Boosted Board, a commercially available electric longboard. But the backpack battery was only a prototype, and now [Andrew] is well on his way to …read more

Long-range Electric Longboard Outlasts Rider

What could be better than a holiday ride past the palm trees and blue waters of a Mediterranean resort town? Perhaps making that ride on a long-range electric longboard of your own design will ice that particular cake.

And when we say long range, we mean it – an estimated 25 miles. The only reason [overclocker_kris] couldn’t come up with an exact number in the test drive seen below is that he got too tired to continue after mile 20. With a bit of juice left in the 64-cell battery pack, built from 18650s harvested from old laptops, the board …read more

3D Printed Electric Longboard Courtesy Of Stratasys

[Tallaustin] worked at Stratasys as an intern this past summer. They let him know that he was welcome to use their fancy industrial printers as much as he’d like. Not to waste such an opportunity he promptly got to work and designed an electric longboard, printable for a mere $8,000.

[Tallaustin] is presumably tall, and confided to Reddit that he weighs in at 210 lbs. For those of us who have had the pleasure of designing for FDM 3D printing, we know that getting a skateboard one can actually skate on without it delaminating somewhere unexpected is pretty difficult if …read more

Hacklet 112 – Skateboard Projects

Skateboarding is a sport that was born of hacking. The identity of the person who first nailed roller skate wheels to a board with a milk crate box is lost to history. Those crate scooters were a staple of the 1940’s and 1950’s neighborhoods. Everyone built their own scooter, so the designs evolved. Eventually the milk crates disappeared. At some point, surfers realized that they could use these wheeled boards to surf the concrete jungle. Things just took off from there. Skateboarding is now a multi-billion dollar industry, but at its heart there are still hackers trying out new designs. …read more
