Fresh hacks every day
Over at the Albuquerque, NM hackerspace Quelab, [Alfred] needed to test a bunch of surface mount LEDs. He ended up building a pair of 3D printed tweezers with a pair of needles attached to the end and a space for a coin cell battery. It works and Quelab got a new tool.
[tech2077] added an … Read the rest
It’s obvious this bike has some extra parts. But look closely and you’ll see the chainring has no chain connecting to it. Pedaling will get you nowhere since [PJ Allen] rerouted the chain in order to drive this bicycle using an electric motor.
He’s got beefy motor which pulls 350 Watts at 24 Volts. For speed control he opted … Read the rest
[Fabian.E] wanted to light up the rims on his bike, but didn’t want to shell out a bunch of clams to get it done. He came up with this system which uses magnets and reed switches to light up one arc or each bicycle wheel.
He calls it the lightrider and it’s based on the revolights concept. That … Read the rest
[Nabil] sent in an awesome electronic bicycle derailleur. Now, instead of pulling a steel cable with a shifting mechanism, [Nabil] can change gears electronically. As a bonus, the derailleur can be controlled by a small bicycle computer, so he’s always in the right gear.
The new electronic derailleur is controlled by a pair of servos with push buttons in … Read the rest
Bicycle commuters are often in a battle with drivers for space on the road. [Hammock Boy] does all of his commuting on two human-powered wheels, and is quite interested in not getting hit by a car. He decided to ply his hobby skills to build a device that helps keep him safe. It’s not just a tail light, it’s a … Read the rest
The bicycle tail and head lights that we’re accustomed to are small add-on modules. This take on the idea uses strips of LEDs to protect you from behind. They’re very bright, matching the pair of LED headlights that are attache to the handlebars.
Apparently [A.Davis12] had some LED strips laying around. There’s not what we’re used to seeing, but … Read the rest
If you want to see what kind of abuse you’re causing your body when out on those single-track rides this system is just the thing. It’s an Arduino data logger that [Wdm006] takes along on the rides with him. When he gets back home, a Python scripts captures the data dump and graphs it. It may sound like a neat … Read the rest
