LumiLor: el centro de todas las miradas nocturnas / Brouhaha trailer elèctrico de bici







LumiLor: el centro de todas las miradas nocturnas

Hemos visto luces delanteras y traseras de todo tipo. Dispositivos que proyectaban un carril a nuestro alrededor. Y ahora llega LumiLor, una pintura especial para pintar el casco, el cuadro de la bicicleta, el sillín, los pedales o cualquier otro objeto susceptible de mejorar nuestra visibilidad.

La ha desarrollado la empresa Darkside Scientific y se llama LumiLor: es una pintura electroluminescente que, además de brillar con enorme fulgor en la oscuridad, da a todo material recubierto una estética muy particular y permite aplicar el dibujo que nosotros deseemos.

LumiLor brilla con igual fuerza con cualquier tipo de superficie (da igual que haya esquinas o zonas más lisas o redondeadas), El objeto recubierto por la pintura se convierte en algo parecido a una lámpara debido a la electroluminiscencia, un fenómeno óptico y eléctrico en el que un material emite luz en respuesta a una corriente eléctrica que fluye a través de él.

LumiLor puede aplicarse en la madera, el vidrio, el metal o el plástico

En este caso, basta encender el interruptor para que el objeto recubierto por LumiLor se ilumine con enorme fuerza, mientras que al apagarlo recupera su aspecto original. Esa es una de las diferencias respecto a otros materiales reflectantes o fosforescentes, además de que en el caso de LumiLor podemos regular la intensidad del brillo.

Otra de sus ventajas es que LumiLor puede aplicarse tanto a objetos metálicos como plásticos, de madera, de vinilo, fibra de carbono o vidrio. Además, está disponible en varios colores (blanco, azul, verde, azul verdoso y naranja), y puede encargarse en otros tantos colores especiales.

El producto, eso sí, debe ser aplicado sólo por profesionales. Estos pueden pedir más información y adquirirlo en la página web de LumiLor.

Modular, electric bike trailer provides strain-free haulage

By C.C. Weiss July 22, 2014


The Rollout Trailer helps motivated cyclists to ditch the car … even when they have heavy gear to haul

The Brouhaha Bike Trailer from Wisconsin-based Rollout Self-Propelled Trailers puts a bit of horsepower behind your two-wheeler. Unlike on some other electric-powered bike trailers, that horsepower doesn't make pedaling any easier; it simply adjusts for the weight of the load so that the cyclist can pedal like normal while carrying everything from a full tailgating set-up to a stand-up paddleboard.

There is already a sizable market of electric cargo bikes and electric bike trailers. Models like the Ridekick are designed to augment pedaling with electric power, providing quicker speeds and less effort.

The Brouhaha is a different kind of e-trailer with a different goal in mind. When he began tinkering with the design several years ago, Brian Bartel sought to build a trailer that could help cyclists replace their cars when hauling all types of large cargo. He wasn't thinking just a plastic bag or two of groceries, but a month's worth of stock for a family of four. He built the trailer to exemplify the motto, "If you can carry it on top of your car, you can tow it with your bicycle and the Brouhaha."

In designing the Brouhaha, Bartel wanted to be sure not to interrupt the exercise of pedaling – that's the part of biking that's good for you, after all. He went about hacking an existing aftermarket e-bike kit, replacing the throttle with a proprietary controller and adding a force sensor to monitor the towing force continually so the controller can adjust motor output as necessary to maintain "zero towing force." So the trailer essentially propels itself while the cyclist pedals like normal.

The Brouhaha trailer is designed to be hitched to any bike. The cyclist simply turns it on and starts pedaling. To ensure the trailer doesn't start motoring before the cyclist is ready, the motor kicks in only after the wheels have spun through one full rotation. The trailer's braking also activates when the cyclist brakes the bike.

A combination of 36-volt (9 Ah or 12 Ah options) sealed lead acid battery and 500-watt motor give the Brouhaha trailer the muscle for some pretty impressive haulage. Rollout estimates that the motor system can handle up to 400 lb (181 kg) of gross trailer weight.

Rollout plans to make the trailer modular so that users can quickly swap out purpose-built racks and extensions for things like canoes, children and groceries. During beta testing, Brian's wife even towed a party set-up of beer, ice, meat, a table and four chairs to a Green Bay Packers game, in a twist on tailgating that demands new terminology – trailer barring?

The Brouhaha is but a prototype for now, but Rollout is running a Kickstarter campaign to raise US$80,000 to polish the hardware and software, smooth out performance and launch a production-ready model. The campaign offers a variety of price points, from a $1,200 three-month rental, to used prototypes starting at $2,500, and a $5,000 first-run production model.

If the campaign is successful, Rollout plans to move toward production this Wisconsin winter, bringing the Brouhaha to market in time for summer 2015. It also advertises customized builds on its website.
