Chamberlain Group—the owner of most of the garage door opener brands like LiftMaster, Chamberlain, Merlin, and Grifco—would like its customers to stop doing smart home things with its "myQ" smart garage door openers. The company recently issued a statement decrying "unauthorized usage" of its smart garage door openers. That's "unauthorized usage" by the people who bought the garage door opener, by the way. Basically, Chamberlain's customers want to trigger the garage door and see its status through third-party smart home apps, and Chamberlain doesn't want that.

Here's the statement:

Chamberlain Group recently made the decision to prevent unauthorized usage of our myQ ecosystem through third-party apps.

This decision was made so that we can continue to provide the best possible experience for our 10 million+ users, as well as our authorized partners who put their trust in us. We understand that this impacts a small percentage of users, but ultimately this will improve the performance and reliability of myQ, benefiting all of our users.

We encourage those who were impacted to check out our authorized partners here: https://www.myq.com/works-with-myq.

We caught wind of this statement through the Home Assistant blog, a popular open source smart home platform. The myQ integration is being stripped from the project because it doesn't work anymore. Allegedly, Chamberlain has been sabotaging Home Assistant support for a while now, with the integration maintainer, Lash-L, telling the Home Assistant blog, "We are playing a game of cat and mouse with MyQ and right now it looks like the cat is winning."

A new BeagleBoard is on the way, full of FPGA hotness: the BeagleV-Fire has been announced. The new $150 Single-Board Computer (SBC) from the pioneering open source BeagleBoard company is built around a RISC-V chip that has FPGA features built in. The BeagleV-Fire is built around the snappily named Microchip PolarFire MPFS025T FCVG484E, a System on a Chip (SoC) that has five Reduced Instruction Set Coding Version 5 (RISC-V) cores and a big chunk of FPGA fabric built in. That means it combines the speed of RISC-V processors with the flexibility of Field Programmable Gate Arrays (FPGA), a big pile of logic gates that can be reprogrammed.

The new BeagleV-Fire includes a sizeable chunk of FPGA to work with: the core chip includes 23 K logic elements and 68 Math blocks, plus 4 Serializer/Deserializer (SerDer) lanes that can throw about 12.7 Gbps of data into and out of the fabric. On the BeagleV-Fire, the main chip is supported by 16 GB of eMMC and 2 GB of LPDDR4 RAM, plus a micro SD slot for extra storage. Gigabit Ethernet is also included, plus USB-C power and a few serial connections for debugging. There is no WiFi built in, but there is an M.2 Key E connection were you could plug in an a wireless adapter if you need it.

Like most other BeagleBoards, the BeagleV-Fire has two headers with 92 pins, which offer access to pretty much every signal on the board, plus lots of analog to digital stuff that works with add-on boards (BeagleBoard refers to them as capes). Also present is the usual 22-pin CSI connector for attaching cameras and other devices.

Want one? They are available for immediate order on BeagleBoard.org or from the usual suspects. It looks like they are already in stock for next-day delivery. If this all sounds familiar, it’s probably because we’ve been posting about this particular board for awhile now, covering both the announcement and first tests.

Ukraine is using $400 drones to destroy tanks:

Facing an enemy with superior numbers of troops and armor, the Ukrainian defenders are holding on with the help of tiny drones flown by operators like Firsov that, for a few hundred dollars, can deliver an explosive charge capable of destroying a Russian tank worth more than $2 million.

[…]

A typical FPV weighs up to one kilogram, has four small engines, a battery, a frame and a camera connected wirelessly to goggles worn by a pilot operating it remotely. It can carry up to 2.5 kilograms of explosives and strike a target at a speed of up to 150 kilometers per hour, explains Pavlo Tsybenko, acting director of the Dronarium military academy outside Kyiv.

“This drone costs up to $400 and can be made anywhere. We made ours using microchips imported from China and details we bought on AliExpress. We made the carbon frame ourselves. And, yeah, the batteries are from Tesla. One car has like 1,100 batteries that can be used to power these little guys,” Tsybenko told POLITICO on a recent visit, showing the custom-made FPV drones used by the academy to train future drone pilots.

“It is almost impossible to shoot it down,” he said. “Only a net can help. And I predict that soon we will have to put up such nets above our cities, or at least government buildings, all over Europe.”

Science fiction authors have been writing about drone swarms for decades. Now they are reality. Tanks today. Soon it will be ships (probably with more expensive drones). Feels like this will be a major change in warfare.
