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.

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.

I’ve attached the Solidworks files too if anyone needs to adapt it in any way.

NEW PRODUCTS – Adafruit PCM5102 I2S DAC with Line Level Output – 112dB SNR + Adafruit PCM5100 I2S DAC with Line Level Output – 100dB SNR

We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality audio playback. That’s great when you have enough processing power to decode WAVs or MP3s in real time. However, we don’t have a good selection of I2S DAC boards…until now! We really love the sounds coming out of the Adafruit PCM5102 I2S DAC with Line Level Output – it’s got clean, excellent-quality, stereo audio and does not need any MCLK or I2C configuration. Literally just pipe some I2S audio in and it ill just work.

The PCM510x comes in a few different varieties: we’ve got the the good-quality PCM5100 with 100dB signa-to-noise/dynamic range, and the excellent-quality PCM5102 with 112dB. The ’02 is a little more expensive but they are both quite good for any use and are pin-compatible so can swap between the two.

This breakout makes I2S digital audio easy: all you need to do is power it with 3~5VDC, and provide BCLK (bit clock), WSEL (left/right word select), and DIN (data in). The data lines are 3.3V logic only. By default it’s configured for I2S but you can also do Left-Justified by toggling the Format pin. Audio can be 16, 24 or 32-bit wide, the chip will automagically determine the right format from the WSEL / BCLK ratio. No MCLK pin is needed, the chip will auto-generate it internally from the bit clock – or you can provide it on the MCLK input if you want.

Other breakout pads provide: filtering (change from normal to low-latency by pulling high), mute (pull low to quickly set the outputs to ground), and de-emphasis for 44.1khz audio (default is off). The audio outputs are also available on breakout pads if you want to wire directly without using the 3.5mm jack.

Audio output is not AC-coupled because it is centered on ground: you can plug it into anything that is either AC coupled or has the same ground reference. Note that this is a line-level output, it cannot drive headphones – the output is for no less than 1K ohm loads!

Each order comes with one I2S Stereo DAC breakout and some header you can solder on for breadboard usage.

NEW PRODUCT – Snap-on Enclosure for Raspberry Pi Pico / W / 2 / 2W

Here is a cute and minimal enclosure for your Pi Pico to keep it safe during use and transport. This case has been custom-designed and 3D printed to accommodate the Micro USB and Bootloader button press with venting through the top cover. No screws or glue are required; simply snap the Pico into the bottom piece and assemble the top piece.

If you want to connect accessories on top, like a PiCowbell, simply leave the cover off.

It’s made of translucent milky white plastic with an SLA process, so you can still easily see the power good LED shining through, and there are no lines or blobbiness to the print.

Comes with two snap-together plastic pieces. No boards, cables, or accessories are included. Designed for the Raspberry Pi Pico, Pico W, Pico 2, and Pico 2 W which you can grab here! It should also work with any Pico-like board as long as the button and micro USB connector are in the same spot.

Image of various stills from FLOW from Blender interview

 

Flow is an enchanting film about the journey of a cat. It is notable for a few reasons – no words are spoken as the cat makes friends, gets out of scrapes, and generally survives a (post human?) drowning world.

It is also the first Academy Award nominated movie made in Blender! With a budget of only $4 Million, it is a testament to the power of open source.

Blender spoke with the director Gints Zilbalodis:

…Blender’s mission, where a small, independent team with a limited budget is able to create a story that moves audiences worldwide, and achieve recognition with over 60 awards, including a Golden Globe for Best Animation and two Oscar nominations.

How did you learn Blender?

I learned a lot online, but it was great to have someone with more experience next to me (Konstantīns). He did a lot of rigging and was much more technical than me, so I could ask him for advice. Sometimes, I needed something specific in the animatic, like the deer moving in a spiral, and he would write a script to automate it. This was before Geometry Nodes.

To celebrate its 45th anniversary, Collider took a look back at the behind the scenes hoopla on the set of Alien.

It all began 45 years ago, with the eerie premise of an interstellar cargo ship in the void of space with a crew encountering a dangerous creature. Alien was the disturbing flip side to the space opera fun of Star Wars: Episode IV — A New Hope (1977). There were no lightsabers and no poetic words on “the force,” instead, the world in Alien was dank and brutal, and the behind-the-scenes stress was almost as bad as getting attacked by a facehugger. The crew, cast, writer, and director might have wished they could have gone up against the nearly indestructible Xenomorph and be done with it, as the making of this sci-fi horror classic was an intense ordeal.

Have you ever heard of an icequake? Icequakes occur when groundwater freezes, causing the ground to tremble similar to a small earthquake. The phenomenon is somewhat rare, but recent cold blasts through the Midwest have folks feeling the freeze in more ways than one.

Because the Midwest isn’t a tectonic hotspot, detection relies on citizen scientists – primarily through the Raspberry Shake! u/dulce1021 has a great post on Reddit on how Raspberry Shake confirmed icequakes in Madison, WI.

TLDR: Icequake confirmed!

This is going to get nerdy, so strap in and prepare to be underwhelmed.

You won’t be surprised to learn that there aren’t a ton of professional high-grade seismometers installed in Wisconsin and streaming real-time data. However, there is a decent network of low-cost citizen science seismometers that we can use. These devices are called Raspberry Shakes and you can buy one yourself for a couple hundred bucks and stream live data to their site, which is where I went looking for data. Wouldn’t you know, in a city as nerdy as Madison, there were a handful of Raspberry Shakes with data to look at.

The James Webb Space Telescope has stepped onto center stage. But fhe value of the venerable old Hubble Telescope will never be lost, becuase its  stunning images still deliver. Here’s more form Astronomy Now:

With Hubble we can get into enormous detail about what’s happening on a holistic scale across the entire disc of the galaxy. You can’t do that with any other large galaxy,” said principal investigator Ben Williams of the University of Washington. Hubble’s sharp imaging capabilities can resolve more than 200 million stars in the Andromeda galaxy, detecting only stars brighter than our Sun. They look like grains of sand across the beach. But that’s just the tip of the iceberg. Andromeda’s total population is estimated to be 1 trillion stars, with many less massive stars falling below Hubble’s sensitivity limit.

Photographing Andromeda was a herculean task because the galaxy is a much bigger target on the sky than the galaxies Hubble routinely observes, which are often billions of light-years away. The full mosaic was carried out under two Hubble programs. In total it required over 1,000 Hubble orbits, spanning more than a decade.
