Google Nest Mini Gutted And Rebuilt To Run Custom Agents

July 23, 2023 by Lewin Day 18 Comments

The Google Nest Mini is a popular smart speaker, but it’s very much a cloud-based Big Tech solution. For those that want to roll their own voice assistant, or just get avoid the corporate surveillance of it all, [Justin Alvey’s] work may appeal. (Nitter)

[Justin] pulled apart a Nest Mini, ripped out the original PCB, and kitted it out with his own internals. He uses the ESP32 as the basis of his design, since it provides plenty of processing power and WiFi connectivity. His replacement PCB also interfaces with the LEDs, mute switch, and capacitive touch features of the Nest Mini, for ease of interaction.

As a demo, he set up the system to work with a custom “Maubot” assistant using the Matrix framework. He hooked it up with Beeper, a messaging client that collates all your other messaging platforms into one easily-accessible place. The assistant employs GPT3.5, prompted with a list of his family, friends, and other details, to enable him to make calls, send messages, and handle natural language queries. The demo itself is very impressive, and we’d love to try setting up a similar assistant ourselves. Seeing two of [Justin’s] builds talking to each other is amusing, too.

If you’re more comfortable working with Google Assistant rather than dropping it entirely, we’ve looked at that kind of thing, too. Video after the break.

Stadia Says Goodbye With Bluetooth And Crap Game

January 15, 2023 by Tom Nardi 26 Comments

In just a few days time, Google’s Stadia game streaming service will finally shut down for good. But not for any technical reason, mind you. Microsoft has managed to demonstrate that streaming modern games over home and even mobile Internet connections is viable with their immensely popular Game Pass Ultimate service, and NVIDIA is making similar inroads with GeForce Now. No, like so many of Google’s failed experiments, they’ve simply decided they don’t want to play anymore and are taking their proverbial ball home back with them.

But not all is lost for those who shelled out money for Stadia’s wares. Not only will Google be refunding any money players spent on games, but a company representative has also announced they will be releasing a tool to unlock the latent Bluetooth capabilities of the service’s custom controller — hopefully stemming a surge of e-waste before it starts.

In a forum thread titled “A Gift from the Stadia Team”, Community Manager [DanFromGoogle] explains that information on how you can enable Bluetooth on the controller will be coming next week. In the meantime, he also announced the immediate release of “Worm Game”, a tech demo that staffers apparently used to test out capabilities of the streaming service before its public release.

That this ridiculously simple game, which looks all the world like something a kid would crank out during an after-school programming class, will be the final title to officially release on Stadia is a stunningly insulting epitaph for the fledgling service. But then, Google seems to have developed a special affinity for mistreating their most loyal ~~cattle~~ users over these last few years.

Enabling Bluetooth on a game controller might not seem like such a big deal, but in this case, it will potentially give the piece of hardware a second chance at life. The Stadia controller is unique in that it uses WiFi to communicate directly over the Internet to Google’s streaming service, so once those servers stop responding, the orphaned device will end up being little more than a curiosity. Although it does technically work over USB, being able to use it wirelessly will not only provide a more modern experience, but help justify its internal batteries.

The last time we mentioned the Stadia controller, it was to document one user’s attempt to rid it of an internal microphone they didn’t feel comfortable with. Now that the service is being put to pasture, we wonder if we’ll start to see more hacks involving the admittedly interesting peripheral. We’ll certainly be keeping an eye out for them, but if you see anything we miss, you know where to send it.

Hacking Google With Plasma

October 10, 2022 by Al Williams 17 Comments

Google recently made some videos to highlight cybersecurity. The video below is episode three, and it tells an interesting story about the first crash test dummy. However, the really interesting part is the story about a USB plasma globe built to hack into computers. One of the people who built that globe tells the story of its insides in a recent blog post that has a bit more technical detail.

The attack in question was in 2012, when people were starting to get the idea that inserting random USB drives into their computers wasn’t a great idea. However, what harm could there be in a cute little plasma globe that just draws power from the port?

Google Quantum, Virtually

July 28, 2022 by Al Williams 18 Comments

Want to try a big quantum computer but don’t have the cash? Google wants to up your simulation game with their “Quantum Virtual Machine” that you can use for free.

On the face of it, it sounds like marketing-speak for just another quantum simulator. But if you read the post, it sounds like it attempts to model effects from a real Sycamore processor including qubit decay and dephasing along with gate and readout errors. This forms what Google calls “processor-like” output, meaning it is as imperfect as a real quantum computer.

If you need more qubits than Google is willing to support, there are ways to add more computing using external compute nodes. Even if you have access to a real machine of sufficient size, this is handy because you don’t have to wait in a queue for time on a machine. You can work out a lot of issues before going to the real computer.

This couldn’t help but remind us of the old days when you had to bring your cards to the central computer location and wait your turn only to find out you’d made a stupid spelling mistake that cost you an hour of wait time. In those days, we’d “desk check” a program carefully before submitting it. This system would allow a similar process where you test your basic logic flow on a virtual machine before suffering the wait time for a real computer to run it.

Of course, if you really need a quantum computer, the simulation is probably too slow to be practical. But at least this might help you work out the kinks on smaller problems before tackling the whole enchilada. What will you do with a quantum computer? Tell us in the comments.

Google, of course, likes its own language, Cirq. If you want a leg up on general concepts with a friendly simulator, try our series.

Ask Hackaday: Would A Scooter Get You Back To The Office?

April 18, 2022 by Kristina Panos 75 Comments

So we’re two plus years into the pandemic at this point. Are you still working from home in the most comfortable clothes ever sewn? We figure that of the lot of you who said goodbye to that drab, tiled carpet in 2020, most have probably heard rumblings about returning to the office. And probably a good portion have at least been forced into a hybrid schedule.

Lots of companies would love to see their employees once again milling about all those ~~glass and steel observation tanks~~ office buildings they pay so much for. And while some are likely just forcing employees to come back, others are offering incentives, such as Google. The tech giant recently partnered with electric scooter manufacturer Unagi to provide a “Ride Scoot” program designed to lure many of Google’s US-based employees back to those brightly-colored code playgrounds they call offices with a fun mode of private transportation. The plan is to offer a full reimbursement of the monthly subscription fee for Unagi’s Model One folding scooter, which retails for $990.

The subscription is normally $49 a month plus a one-time $50 sign-up fee, but this amount will be slightly discounted (and waived) for eligible Google employees. There is one caveat to the system: an employee must use the scooter for a minimum of nine commutes to the office per month, although Google says they’re gonna be a bro about it and use the honor system.

Hackaday Links: February 6, 2022

February 6, 2022 by Dan Maloney 41 Comments

Last week, the news was filled with stories of Jack Sweeney and his Twitter-bot that tracks the comings and goings of various billionaires in their private jets. This caught the attention of the billionaire-iest of them all, one Elon Musk, who took exception to the 19-year-old’s feat of data integration, which draws from a number of public databases to infer the location of Elon’s plane. After Jack wisely laughed off Elon’s measly offer of $5,000 to take the bot down, Elon ghosted him — pretty childish behavior for the richest man on the planet, we have to say. But Jack might just have the last laugh, as an Orlando-based private jet chartering company has now offered him a job. Seems like his Twitter-bot and the resulting kerfuffle is a real resume builder, so job-seekers should take note.

Here’s hoping that you have a better retirement plan than NASA. The space agency announced its end-of-life plans for the International Space Station this week, the details of which will just be a run-up to the 2031 de-orbit and crash landing of any remaining debris into the lonely waters of Point Nemo. The agency apparently sees the increasingly political handwriting on the ISS’s aging and sometimes perforated walls, and acknowledges that the next phase of LEO space research will be carried out by a fleet of commercial space stations, none of which is close to existing yet. Politics aside, we’d love to dig into the technical details of the plan, and see exactly what will be salvaged from the station before its fiery demise, if anything. The exact method of de-orbiting too would be interesting — seems like the station would need quite a bit of thrust to put on the brakes, and might need the help of a sacrificial spacecraft.

“You break it, you fix it,” is a philosophy that we Hackaday types are probably more comfortable with than the general public, who tend to leave repairs of broken gear to professionals. But that philosophy seems to be at the core of Google’s new Chromebook repair program for schools, which encourages students to fix the Chromebooks they’re breaking in record numbers these days. Google is providing guidance for schools on setting up complete Chromebook repair facilities, including physical layout of the shop, organization of workflows, and complete repair information for at least a couple of popular brands of the stripped-down laptops. Although the repairs are limited to module-level stuff, like swapping power supplies, we still love the sound of this. Here’s hoping that something like this can trigger an interest in electronics for students that would otherwise never think to open up something as complicated as a laptop.

Back in July, we took note of a disturbing report of an RTL-SDR enthusiast in Crimea who was arrested for treason, apparently based on his interest in tracking flights and otherwise monitoring the radio spectrum. Now, as things appear to be heating up in Ukraine again, our friends at RTL-SDR.com are renewing their warning to radio enthusiasts in the area that there may still be risks. Then as now, we have little interest in the politics of all this, but in light of the previous arrest, we’d say it pays to be careful with how some hobbies are perceived.

And finally, aside from the aforementioned flight-tracking dustup, it’s been a tough week for Elon and Tesla. Not only have 817,000 of the expensive electric vehicles been recalled over something as simple as a wonky seatbelt chime, but another 54,000 cars are also being recalled for a software bug that causes them to ignore stop signs in “Full Self-Driving” mode. We’re not sure if this video of this Tesla hell-ride has anything to do with that bug, but it sure illustrates the point that FSD isn’t really ready for prime time. Then again, as a former Boston resident, we can pretty safely say that what that Tesla was doing isn’t really that much different than the meat-based drivers there.
