This projector-powered augmented reality game takes climbing to a whole new level

Jon Cheng had a brilliant idea to improve his rock climbing skills and have fun while doing it. Using some basic web technologies and a projector, he turned the climbing wall of his local gym into a mini-arcade game. Cheng recently demoed his game during the community night at his local climbing gym, Brooklyn Boulders Somerset. As noted by Core77, the response from Cheng’s home gym and the Internet has been outstanding.

The premise of the game is simple. Climbers are challenged to tap the dots on the wall in order as fast as possible. Dots are projected on the wall by a projector which is connected to a computer that is controlling the game. The dots are placed according to the holds on the wall making it possible for players to climb and tap their way through the game. The placement and order of the dots were designed to accommodate newer climbers as well as challenge experienced climbers. They also are dynamic and can be modified for different climbing walls.

Players are allowed to use any hand hold, technique, or route they want, they just have to tap according to the order of the dots as displayed on the wall. Scoring is done manually by the operator with a leaderboard keeping track of the climbers who complete the course in the shortest amount of time.

Following this demonstration, Cheng was approached by the climbing gym and asked to bring his game to future events. When news of his game went viral, other climbing facilities contacted Cheng about modifying his technology and bringing it to their gyms. Cheng used javascript, ruby on rails and other web-based programming languages to code the timed challenge, which is controlled manually in version 1.0.

Cheng is looking to improve the game in version 2.0 by adding some automation into the mix. The team is developing a motion capture system using a USB webcam that would track climbers and score them automatically. There also is the possibility of adding sensors to the hand holds to provide details on the path each player climbs.

Zoox recalls robotaxis after Las Vegas crash, citing software fix
zoox recall crash 1739252352 robotaxi side profile in dark mode

Amazon's self-driving vehicle unit, Zoox, has issued a voluntary safety recall after one of its autonomous vehicles was involved in a minor collision in Las Vegas. The incident, which occurred in April 2025, led the company to investigate and identify a software issue affecting how the robotaxi anticipates another vehicle’s path.
The recall, affecting 270 Zoox-built vehicles, was formally filed with the National Highway Traffic Safety Administration (NHTSA). Zoox said the issue has already been addressed through a software update that was remotely deployed to its fleet.
Zoox’s robotaxis, which operate without driving controls like a steering wheel or pedals, are part of Amazon’s entry into the autonomous driving space. According to Zoox’s safety recall report, the vehicle failed to yield to oncoming traffic while making an unprotected left turn, leading to a low-speed collision with a regular passenger car. While damage was minor, the event raised flags about the system’s behavior in complex urban scenarios.
Establishing safety and reliability remain key factors in the deployment of the relatively new autonomous ride-hailing technology. Alphabet-owned Waymo continues to lead the sector in both safety and operational scale, with services active in multiple cities including Phoenix and San Francisco. But GM’s Cruise and Ford/VW-backed Argo AI were forced to abandon operations over the past few years.
Tesla is also expected to enter the robotaxi race with the launch of its own service in June 2025, leveraging its Full Self-Driving (FSD) software. While FSD has faced heavy regulatory scrutiny through last year, safety regulations are expected to loosen under the Trump administration.
Zoox, which Amazon acquired in 2020, says it issued the recall voluntarily as part of its commitment to safety. “It’s essential that we remain transparent about our processes and the collective decisions we make,” the company said in a statement.

Mitsubishi’s back in the EV game—with a new electric SUV coming in 2026
mitsubishi bev 2026 momentum 2030 line up

Mitsubishi is officially jumping back into the U.S. electric vehicle scene—and this time, it’s not just dipping a toe. The company confirmed it will launch a brand-new battery-electric SUV in North America starting in summer 2026, marking its first fully electric model here since the quirky little i-MiEV left the stage back in 2017.
The new EV will be a compact crossover, and while Mitsubishi is keeping most of the juicy details under wraps, we do know it’ll be based on the same next-gen platform as the upcoming Nissan Leaf. That means it’ll ride on the CMF-EV architecture—the same one underpinning the Nissan Ariya—which supports ranges of up to 300+ miles. So yeah, this won’t be your average entry-level EV.
Designed in partnership with Nissan, the new model will be built in Japan and shipped over to U.S. shores. No word yet on pricing, battery size, or even a name, but Mitsubishi has made it clear this EV is just the beginning. As part of its “Momentum 2030” plan, the company promises a new or updated vehicle every year through the end of the decade, with four electric models rolling out by 2028. And yes, one of those might even be a pickup.
Mitsubishi says the goal is to give customers “flexible powertrain options,” which is marketing speak for: “We’ll have something for everyone.” So whether you're all-in on electric or still into gas or hybrid power, they're aiming to have you covered.
This mystery EV will eventually sit alongside Mitsubishi’s current U.S. lineup—the Outlander, Outlander PHEV, Eclipse Cross, and Outlander Sport—and help the brand move beyond its current under-the-radar status in the electric world.
In short: Mitsubishi’s finally getting serious about EVs, and if this new SUV lives up to its potential, it might just put the brand back on your radar.

Toyota unveils 2026 bZ: A smarter, longer-range electric SUV
toyota bz improved bz4x 2026 0007 1500x1125

Toyota is back in the electric SUV game with the 2026 bZ, a major refresh of its bZ4X that finally delivers on two of the biggest demands from EV drivers: more range and faster charging.
The headline news is the improved driving range. Toyota now estimates up to 314 miles on a single charge for the front-wheel-drive model with the larger 74.7-kWh battery—about 60 miles more than the outgoing bZ4X. All-wheel-drive variants also get a boost, with up to 288 miles of range depending on trim.
Charging speeds haven’t increased in terms of raw kilowatts (still capped at 150 kW for DC fast charging), but Toyota has significantly improved how long peak speeds are sustained. With preconditioning enabled—especially helpful in colder weather—the new bZ can charge from 10% to 80% in about 30 minutes. Also new: Plug and Charge support for automatic payment at compatible stations and full adoption of the North American Charging Standard (NACS), meaning access to Tesla Superchargers will be standard by 2026.
Under the hood, or rather the floor, Toyota has swapped in higher-performance silicon carbide components to improve efficiency and power delivery. The AWD version now produces up to 338 horsepower and sprints from 0–60 mph in a brisk 4.9 seconds.
Toyota didn’t stop at just the powertrain. The exterior has been cleaned up, with body-colored wheel arches replacing the black cladding, and a sleeker front fascia. Inside, a larger 14-inch touchscreen now houses climate controls, giving the dash a more refined and less cluttered appearance. There’s also more usable storage thanks to a redesigned center console.
With the 2026 bZ, Toyota seems to be responding directly to critiques of the bZ4X. It’s faster, more efficient, and more driver-friendly—finally bringing Toyota’s EV efforts up to speed.
