Jewelry can lose its shine over time due to dirt, oils and everyday wear, but a good cleaning can restore its sparkle. Whether you have solid gold, sterling silver jewelry or costume jewelry, knowing how to clean jewelry properly helps maintain its beauty.

Manga, the Japanese form of illustrated narratives, is thriving as a medium and a business. With the advent of the internet, it's become increasingly easy to consume manga online, instead of purchasing (or borrowing) the physical editions of the work.

A versatile modular holder designed for dusters or other cylindrical objects that fit within its rings. The system is fully expandable, allowing you to add as many rings as needed. For a standard duster, a setup with two rings and one end piece typically works well.

A nice way to stack away your dusters into a cabinet, or similar.

A simple and sturdy bird/critter feeder designed to mount onto any standard U-channel signpost (the kind commonly used for road signs). I installed one in my workplace parking lot so I could watch birds during my breaks.

• Attaches with just two M5 screws (easy installation).
• Features a 3mm drain hole to prevent rainwater buildup.
• The drain hole can be plugged to convert it into a birdbath.
• If printing with UV-sensitive filament, I recommend applying a clear UV protectant. For added durability, dusting the final layer with Titanium Dioxide powder can help reflect UV light and reduce gloss.

It’s a straightforward design that does the job well, whether for feeding birds or providing a small water source.

Mark Gurman, with a blockbuster scoop for Bloomberg:

Apple Inc. is undergoing a rare shake-up of its executive ranks, aiming to get its artificial intelligence efforts back on track after months of delays and stumbles, according to people familiar with the situation.

Chief Executive Officer Tim Cook has lost confidence in the ability of AI head John Giannandrea to execute on product development, so he’s moving over another top executive to help: Vision Pro creator Mike Rockwell. In a new role, Rockwell will be in charge of the Siri virtual assistant, according to the people, who asked not to be identified because the moves haven’t been announced.

Rockwell will report to software chief Craig Federighi, removing Siri completely from Giannandrea’s command. Apple is poised to announce the changes to employees this week. The iPhone maker’s senior leaders — a group known as the Top 100 — just met at a secretive, annual offsite gathering to discuss the future of the company. Its AI efforts were a key talking point at the summit, Bloomberg News has reported. [...]

My quick take on this is that it’s a turf battle that Craig Federighi just won. It’s not just putting a new executive in charge of Siri, it’s moving Siri under Federighi’s group.

How Gurman got this scoop before Apple had announced the changes — even internally — is rather unbelievable. It’s not “Bloomberg” that got this scoop. It’s Mark Gurman. And trust me, Apple PR did not leak this to him deliberately. I’m sure they’re now accelerating an announcement, at least internally, framing it on their own terms. I can only guess that Gurman hinted at his sourcing in the passage above: Tim Cook must have announced these changes at the Top 100 retreat this week, and at least two of those attendees leaked the news to Gurman. Unprecedented.

Also:

Rockwell is currently the vice president in charge of the Vision Products Group, or VPG, the division that developed Apple’s headset. As part of the changes, he’ll be leaving that team and handing the reins to Paul Meade, an executive who has run hardware engineering for the Vision Pro under Rockwell.

I don’t find it surprising at all that Rockwell was given this task.

Giannandrea will remain at the company, even with Rockwell taking over Siri. An abrupt departure would signal publicly that the AI efforts have been tumultuous — something Apple is reluctant to acknowledge. Giannandrea’s other responsibilities include oversight of research, testing and technologies related to AI. The company also has a team reporting to Giannandrea investigating robotics.

This I find a little surprising. But maybe I shouldn’t. I don’t buy Gurman’s argument that dismissing Giannandrea would “signal publicly that the AI efforts have been tumultuous”. Apple already signaled that publicly when they announced that all of the ambitious features for Siri and Apple Intelligence that were promised for this year’s OS cycle would be postponed until next year’s OS cycle. That’s public tumult. But I mean, you can see for yourself that Apple’s AI efforts have been “tumultuous” by asking Siri on your iPhone, right now, what month it is.

What Apple needs to signal is that they don’t expect to deliver a significantly better Siri without making significant changes to the team behind Siri.

But maybe the answer is as simple as that Giannandrea is good at leading and managing teams doing advanced research that is abstracted from product. So move the products out of his division and into Federighi’s, and put someone who knows how to ship directly in charge of Siri. Leave Giannandrea in charge of a division focused on research and technology. Attention has moved on from “machine learning” to LLMs, but Apple’s machine learning game has gotten very good.

This week’s EYE ON NPI is trendy and buzzy, it’s Boréas Technologies’ BOS1931 High-Efficiency Piezo Driver. This chip is a compact way to add powerful high-voltage piezo drive to any product, combining three chips: power supply, waveform generator and driver.

With a complete I2C/I3C interface that you can connect to any microcontroller/processor it’s the most advanced all-in-one piezo driver we’ve seen!

Piezo discs are multi-use devices that convert mechanical movement to electrical signal, and vice-versa. They’re most often seen as electrical-to-mechanical converters such as piezo beepers where an AC signal, usually 3 to 6V peak-to-peak square wave, is applied across the disk. The frequency of the wave is translated into a sound frequency. It doesn’t have the same fidelity as a magnetic speaker, but it’s much thinner, less expensive for the component and driving circuitry, and for 2 to 4 KHz beeps, it’s just fine.

Piezos can also be used the opposite way, where mechanical stress on the crystal is translated into an electrical signal. In this way it can be used as a switch or force sensor, again usually a few microamperes’ worth of current is generated. For these basic uses, your standard microcontroller pin, or at best an H-Bridge will work just fine: you can drive piezos differentially to get more Vpp across the disc, but essentially we’re still talking about only a few volts.

There are some times when you want to make a piezo really ‘loud’ – that is, putting 100+ Volts across the crystal to generate a big mechanical response. This is often not for audible use cases, after all if you wanted to do that you’d just use a magnetic speaker that can get to many many Watts of output efficiently. For example, when using a piezo to generate sonar waves for sensing objects or distance.

Or, in this particular use case, for creating an ultra thin liquid pump that can be used for portable devices in place of a heatsink or fan.

FYI there’s two variants of the chip: the BOS1931 and the BOS1921. The ’31 can only do piezo driving. The ’21 can do sensing as well as driving, so it can be used for force-feedback products. In this particular EYE ON NPI, we’ll just be chatting about the driving capabilities of both.

So, while we can do basic sensing/beeping with a few volts – when we want to have significant motion for blasting sonar or moving fluid around, we can only increase the movement by increasing the peak-to-peak voltage. Each piezo you buy will have a voltage rating – and you will need a boost converter to generate that peak-to-peak. For the BOS19 series of chips, you can get +-95V, so 190Vpp max, which will drive any piezo you find, and you only need 3~5V input thanks to a built-in DC/DC boost converter.

Boréas didn’t stop there. Not only do you get a booster, but also a full waveform manager with I2C/I3C control. You can can fill up a FIFO buffer with waveform bytes to generate different shapes. There’s a sine generator you can control with an envelope creator.

Or, you can piece together waveform shapes for different pump/haptic behavior, giving you the customizability of a byte-wise waveform generator with the simplicity of a sine generator.

They even have a Haptics Studio to help you craft the waveform you want.

The BOS1931 and the BOS1921 come in two packages: an easy-to-layout-and-solder QFN and a tiny-and-advanced BGA. Both have the same core, so just pick whether you need simplicity or small size. Since it’s a pretty serious boost converter and driver – the piezo connects directly to the output pins – you’ll need to watch your layout. Check the datasheet for their recommended setup to make sure you don’t have excessive power loss or EMI.

If you want to get started quickly, the BOS1921-KIT-B01 evaluation board will let you use their configuration software to quickly determine how your piezo actuator or sensor response to the waveform generator and booster before you start laying out the components on a prototype PCB.

If you have some serious piezo-ing you need to get moving, the Boréas Technologies’ BOS1931 High-Efficiency Piezo Driver can do everything from voltage generation, waveform shaping, and differential driving. And best of all it’s in stock right now at Digi-Key for immediate shipment! Order today and DigiKey will pick and pack your order in an instant so that you can be vibin’ with your fancy new piezo controller by tomorrow afternoon.

My design allows you to mount the camera at a 45 degree, but drilled to the left hand side of the wall.

My design includes a plate that is attached to the ring doorbell mount, this is so the camera can sit flush to the corner mount.
