Mountable Laserlight Projector Creates a Personal Bike Lane for Cyclists

All the blinking lights and reflectors in the world aren't enough to prevent your bike from disappearing into a truck's blind spot. But what if you could extend the length of your bike by an 20 extra feet with the click of a button? That's the concept behind the Laserlight Core, a product currently raising funds on Kickstarter, Fast Company reports.

Laserlight resembles a small flashlight, and it attaches easily to the front of your handlebars. When biking, you can switch it on to project a laser image of a green bike symbol onto the street several yards in front of you. If the driver of a van, truck, or bus can't see your actual bike in their mirror, the idea is that the light will make them aware of your presence. The projection is about the width of a bike lane, so it may also encourage drivers to give cyclists more road space than they would have otherwise. According to an independent study on the light from Transport for London, bikers with Laserlight are about 97 percent visible at night to drivers in vans (compared to 65 visibility with a standard LED light).

Emily Brooke came up up with the concept seven years ago as a design student at England's University of Brighton. After a frighteningly close encounter with a van while biking, she wondered if she could invent a way to get the attention of drivers even when she was stuck squarely in their blind spots.

Her product, originally dubbed Blaze, launched on Kickstarter in 2012. The campaign was a success, and now she's returning to the crowdfunding platform with a new-and-improved version of the item. Laserlight Core is easier to mount than its predecessor and it also projects a clearer image. You can reserve yours with a pledge of $75 or more with shipping estimated for December of this year. (It makes a great gift for the dedicated cyclist in your life, too.)

This tiny air conditioner fan, which touts a 4.6-star rating, is unique because it plugs in with a USB cable, so you can hook it up to a laptop or a wall outlet converter to try out any of its three fan speeds. This won't chill a living room, but it does fit on a nightstand or desk to help cool you down in stuffy rooms or makeshift home offices that weren't designed with summer in mind.

New Virtual Tool Lets You Rickroll Your Next Zoom Meeting

Anyone who says the Rickroll is played out isn't thinking big enough. The classic internet prank—in which web users are tricked into watching the music video for "Never Gonna Give You Up" by Rick Astley—has been reimagined countless times in a variety of contexts. Now, Rickrolling has entered the Zoom era.

As Gizmodo reports, creative technologist Matt Reed has invented a genius tool that lets you Rickroll your coworkers. After receiving an invitation to a Zoom meeting you're not excited to attend, head to InviteRick.com and submit the invite link.

The tool is still in beta, and Reed has to initiate every Rickroll manually. That means Rick is only available to make surprise Zoom performances on weekdays between 10 a.m. and 4 p.m. EST. Once you've signed up for the service, you'll be added to a queue and updated on when to expect Rick to make his appearance. When the pop icon does eventually crash your Zoom, he'll stick around for approximately 15 seconds before making his exit. Hopefully that's enough time to completely derail the meeting.

InviteRick.com may only be around for a short while (Reed admits it likely violates Zoom's terms of service), so spread that '80s corniness while you still can. In the meantime, check out these epic Rickrolls from a simpler time in history.
