These little stackable magnetic Arduino boards work with LEGO making building a snap

Now there’s even more you can do with LEGOs, besides stacking them and plucking them out of the bottom of your feet. Microduino’s new generation of little stackable Arduino modules, mCookie, is both magnetic and Lego-compatible. If you thought you could do everything with Legos before, well, you were pretty much right, but now it’s a hell of a lot easier.

Ay visiting the strong online Lego and Arduino builder communities, you can find plenty tech online to ooh and ahh over. Microduino took the suggestions offered by those communities on their first campaign in 2013 and ended up with its mCookie modules, which are remarkably easy to use. Soon, Microduino’s mCookies are going to be available to everyone; the company is finishing up shipments to backers.

Since September 2013, when the first Microduino campaign grew to funding success on Kickstarter, the web community has grown by leaps and bounds. There are an increasing number of tutorials, instructions, and project suggestions available online, giving builders a greater support system. The Microduino wiki is growing page by page, and has about 75 tutorials posted so far to get users started.

There are a bunch of Arduino model kits out there, but they generally aren’t as simple or as flexible as mCookie. For example, Microduino’s quarter-sized mCookie modules connect magnetically, so you don’t have to solder connections. And their unique 27 pogo pin setup keeps damage to a minimum when you stack the modules.

And, of course the little circular connectors so familiar from childhood let you snap the modules onto Lego blocks. The holes on the mCookies also fit M2 screws so your designs will be tougher than if they were attached only with the Lego snap combined with magnetism.

The colors define the module categories, and do so with a clear inspiration from Lego. Red is for core modules, blue is for communication modules like Wi-Fi, or Bluetooth. Yellow is for functions like GPS and audio, and teal is for extensions like motors or amplifiers.

Arduino’s been around for 10 years, and its open source nature means there are a lot of projects already out there as examples. Easily available info and project plans make it a good fit both for pros building their own new designs and writing programs for them with Ardunio IDE, and for beginners working on basic downloaded plans using the Scratch graphic tool. The videos show how easy it is using a music player as an example.

Microduino Studio began shipping mCookies to Kickstarter backers in the beginning of September, and the firm just changed the order status from pre-sale to actual-sale on their website. mCookie Kits are set up like college classes offerings. 101 is the basic kit that comes with eight different module types: Core with USB, BLE 4.0, 8M, a hub, mic, buzzer, and two LEDcolor and Crash modules. 201, the advanced kit, comes with 16 modules, all of the basic kit plus an amplifier, audio, RTC, OLED, temperature and humidity, light sensor, passive infrared and infrared sensor modules. The 301 kit has every mCookie an expert could want, adding Wi-Fi, 10DOF, motor, servo, shake sensor, joystick, color detector, and duoV modules to everything that comes in 101 and 201.

The basic kit goes for $80, the advanced kit is $150, and the expert is $260. There’s also a family kit that comes with all three for $480.

Toyota shifts gears: 15 New EVs and a million cars by 2027
Front three quarter view of the 2023 Toyota bZ4X.

After years of cautiously navigating the electric vehicle (EV) market, Toyota is finally ramping up its commitment to fully electric vehicles.
The Japanese automaker, which has long relied on hybrids, is now planning to develop about 15 fully electric models by 2027, up from five currently. These models will include vehicles under the Toyota and Lexus brands, with production expected to reach 1 million units annually by that year, according to a report from Nikkei.
This strategy marks a significant shift for Toyota, which has thus far remained conservative in its approach to electric cars. The company sold just 140,000 EVs globally in 2024—representing less than 2% of its total global sales. Despite this, Toyota is aiming for a much larger presence in the EV market, targeting approximately 35% of its global production to be electric by the end of the decade.
The Nikkei report suggests the company plans to diversify its production footprint beyond Japan and China and expanding into the U.S., Thailand, and Argentina. This would help mitigate the impact of President Donald Trump’s 25% tariffs on all car imports, as well as reduce delivery times. Toyota is also building a battery plant in North Carolina.
For now, Toyota has only two fully electric vehicles on the U.S. market: The bZ4X  and the Lexus RZ models. The Japanese automaker is expected to introduce new models like the bZ5X and a potential electric version of the popular Tacoma pickup.
Separately, Toyota and Honda, along with South Korea’s Hyundai, all announced on April 4 that they would not be raising prices, at least over the next couple of months, following the imposition of U.S. tariffs. According to a separate Nikkei report, Toyota’s North American division has told its suppliers that it will absorb the extra costs of parts imported from Mexico and Canada. Another 25% for automotive parts imported to the U.S. is slated to come into effect on May 3.

Tesla, Warner Bros. dodge some claims in ‘Blade Runner 2049’ lawsuit, copyright battle continues
Tesla Cybercab at night

Tesla and Warner Bros. scored a partial legal victory as a federal judge dismissed several claims in a lawsuit filed by Alcon Entertainment, a production company behind the 2017 sci-fi movie Blade Runner 2049, Reuters reports.
The lawsuit accused the two companies of using imagery from the film to promote Tesla’s autonomous Cybercab vehicle at an event hosted by Tesla CEO Elon Musk at Warner Bros. Discovery (WBD) Studios in Hollywood in October of last year.
U.S. District Judge George Wu indicated he was inclined to dismiss Alcon’s allegations that Tesla and Warner Bros. violated trademark law, according to Reuters. Specifically, the judge said Musk only referenced the original Blade Runner movie at the event, and noted that Tesla and Alcon are not competitors.
"Tesla and Musk are looking to sell cars," Reuters quoted Wu as saying. "Plaintiff is plainly not in that line of business."
Wu also dismissed most of Alcon's claims against Warner Bros., the distributor of the Blade Runner franchise.
However, the judge allowed Alcon to continue its copyright infringement claims against Tesla for its alleged use of AI-generated images mimicking scenes from Blade Runner 2049 without permission.
Alcan says that just hours before the Cybercab event, it had turned down a request from Tesla and WBD to use “an icononic still image” from the movie.
In the lawsuit, Alcon explained its decision by saying that “any prudent brand considering any Tesla partnership has to take Musk’s massively amplified, highly politicized, capricious and arbitrary behavior, which sometimes veers into hate speech, into account.”
Alcon further said it did not want Blade Runner 2049 “to be affiliated with Musk, Tesla, or any Musk company, for all of these reasons.”
But according to Alcon, Tesla went ahead with feeding images from Blade Runner 2049 into an AI image generator to yield a still image that appeared on screen for 10 seconds during the Cybercab event. With the image featured in the background, Musk directly referenced Blade Runner.
Alcon also said that Musk’s reference to Blade Runner 2049 was not a coincidence as the movie features a “strikingly designed, artificially intelligent, fully autonomous car.”

Audi halts vehicle deliveries to the U.S. as it mulls impact of tariffs
2021 Audi Q5

If you’d been thinking of buying an Audi, now might be the time.  The German brand, owned by the Volkswagen Group, has announced it would halt shipments to the U.S. in the wake of President Donald Trump’s 25% tariffs on all imported vehicles.
Audi is currently holding cars that arrived after the tariffs took effect, on April 3, in U.S. ports. But it still has around 37,000 vehicles in its U.S. inventory, which should be able to meet demand for about two months, according to Reuters.
Automakers on average hold enough cars to meet U.S. demand for about three months, according to Cox Automotive.
Audi should be particularly affected by the tariffs: The Q5, its best-selling model in the U.S., is produced in Mexico, while other models, such as the A3, A4, and A6 are produced in Germany.
Holding shipments is obviously a temporary measure to buy time for Audi and parent company Volkswagen. If tariffs stay in place, vehicle prices would likely have to go up accordingly, unless some production is shifted to the U.S. Volkswagen already has a plant in Chattanooga, Tennessee, and is planning a new plant in South Carolina. That latter plant, however, isn’t expected to be operational until 2027 and is currently dedicated to building electric vehicles for VW’s Scout Motors brand.
Other global automakers have also taken drastic measures in response to Trump’s tariffs. Jaguar Land Rover on April 5 said it is pausing shipments of its its UK-made cars to the United States this month. The British sports-luxury vehicle maker noted that the U.S. market accounts for nearly a quarter of its global sales, led by the likes of Range Rover Sports, Defenders, and Jaguar F-PACE.
And on April 3, Nissan, the biggest Japanese vehicle exporter to the United States, announced it will stop taking new U.S. orders for two Mexican-built Infiniti SUVs, the QX50 and QX55.
