Keep Pedaling to Keep Playing

Posted on by

It’s been said that the best way to tackle the issue of childhood obesity would be to hook those children’s video game consoles up to a pedal-powered generator. Of course, this was said by [Alex], the creator of Cykill. Cykill interfaces an Xbox to an exercise bike, so to keep the video game going you’ll have to keep pedaling the bike.

While there is no generator involved in this project, it does mimic the effect of powering electronics from a one. The exercise bike has a set of communications wires, which are connected to a relay on the Xbox’s power …read more

Simple Electric Bike Conversion from 3D-Printed Parts

Posted on by

Challenge: Perform an electric conversion on a bicycle. Problem: No significant metal working skills or equipment. Solution: 3D print everything needed to electrify the bike.

At least that’s the approach that [Tom Stanton] took to his electric bike build. Having caught the electric locomotion bug on a recent longboard build, [Tom] undertook the upgrade of a cheap “fixie,” or fixed-gear bike. His delta printer was big enough for the motor mount and weather-resistant ESC enclosure, but he needed to print the drive pulley in four quadrants that were later glued together. We can’t say we hold much faith in the …read more

Suffer No Substitutes — The Hudspith Steam Bicycle Is One-Of-A-Kind

Posted on by

In a bit of punky, steam-based tinkering, Brittish engineer [Geoff Hudspith]’s obsession for steam and passion for cycles fused into the Hudspith Steam Bicycle.

Built and improved over the past thirty years, the custom steam engine uses a petrol and kerosene mix for fuel, reaching a top speed of 32km/h and has a range of 16km on one tank of water. While in motion, the boiler is counter-balanced by the water tank on the rear as well as the flywheel, water pump, and the other components. However, [Hudspith] says he doesn’t have an easy go of it carrying the bike …read more

Arduino + Geometry + Bicycle = Speedometer

Posted on by

It is pretty easy to go to a big box store and get a digital speedometer for your bike. Not only is that no fun, but the little digital display isn’t going to win you any hacker cred. [AlexGyver] has the answer. Using an Arduino and a servo he built a classic needle speedometer for his bike. It also has a digital display and uses a hall effect sensor to pick up the wheel speed. You can see a video of the project below.

[Alex] talks about the geometry involved, in case your high school math is well into your …read more

Light Rider: A Lightweight 3D Printed Electric Motorcycle!

Posted on by

It sounds like the name of a vehicle in some sci-fi tale, but that fiction is only a short leap from reality. Light Rider is, in fact, an electric motorcycle with a 3D printed frame that resembles an organic structure more than a machine.

Designed by the Airbus subsidiary [APWorks], the largely hollow frame was devised to minimize weight while maintaining its integrity and facilitating the integration of cables within the structure. The frame is printed by melting a sea aluminium alloy particles together into thousands of layers 30 microns thick. Overall, Light Rider’s frame weighs 30% less than similar …read more

Snowed-In in the City? The Snow Bike Will Get You Where You Need To Go

Posted on by

If have ever gone snowmobiling, you may have thought about how to revive that thrill in the more confined atmosphere of an urban environment — to say nothing of their utility. In anticipation of heavy snowfall  over the winter in his hometown, [Ben] stripped the essence of the snowmobile down as an emergency vehicle and reshaped it into the Snow Bike.

This compact, winter transportation solution uses an e-bike controller, a chopped up ski, and a heavy snowblower track and a large RC plane motor for power all strapped onto a modified mountain bike frame. The motor mount is machined …read more

Barely-There GSM GPS Tracker

Posted on by

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 …read more

Hackaday Prize Entry: An Electric Bike And A Dashboard

Posted on by

Over the last few years, powerful brushless motors have become very cheap, batteries have become very powerful, and the world of quadcopters has brought us very capable electronic speed controls. Sounds like the perfect storm for a bunch of electric bike hacks, right? That’s what [bosko] is doing for his Hackaday Prize Entry. He’s building an e-bike with a big motor and an electronic dashboard, because a simple throttle switch would never do.

There are two parts to [bosko]’s bike, with the front brain box consisting of GPS, an OLED display, analog throttle, and a few wireless modules to connect …read more

DIY Pressure Regulator for Exciting SCUBA

Posted on by

To get a SCUBA certification, a prospective diver will need to find a dive shop and take a class. Afterwards, some expensive rental equipment is in order. That is, unless you’re [biketool] who has found a way to build some of his own equipment. If you’re looking for a little bit of excitement on your next dive, this second stage regulator build might be just the thing for you.

It’s worth noting that [biketool] makes it explicitly clear that this shouldn’t be used on any living being just yet. The current test, though, was at 120 PSI using some soda …read more
