Like the traditional PIR sensor, RCWL-0516 is a widely popular sensor that also detects movements and is used in Alarms or for security purposes. This sensor uses a “microwave Doppler radar” technique to detect moving objects within its range. It has a sensitivity range of ~7 meters and that is very useful for multiple applications.

OPT4048 - a "tri-stimulus" light sensor 🔴🟢🔵

We were chatting in the forums with someone when the OPT4048 (https://www.digikey.com/en/products/detail/texas-instruments/OPT4048DTSR/21298553) came up. It's an interesting light sensor that does color sensing but with diodes matched to the CIE XYZ color space. This would make them particularly good for color-light tuning. We made a cute breakout for this board. Fun fact: it's 3.3V power but 5V logic friendly.

Scientists uncover advanced manufacturing strategies for piezoelectric and triboelectric tactile sensors

Piezoelectric and triboelectric tactile sensors are designed to convert mechanical stimuli into electrical signals, making them critical components in intelligent systems. Piezoelectric sensors leverage voltage generation through mechanical stress in non-centrosymmetric materials, such as quartz and polyvinylidene fluoride (PVDF), while triboelectric sensors operate on contact-induced charge transfer. Both sensor types offer unique advantages, including self-powered functionality and high sensitivity, but also face challenges, such as material brittleness and environmental limitations. A team of researchers led by Professor Hanjun Ryu from Chung-Ang University, South Korea, has introduced novel manufacturing strategies to overcome these limitations. The team's paper is published in the International Journal of Extreme Manufacturing.

Prototype time!

My first project in 2025. It was nice trip down memory lane, returning to 8bit micro controller. I am still trying to get the hang of the printing setup and new filament so the printing is pretty poor on this one.

AH I REMEMBERED WHAT I WAS GONNA SAY EARLIER but it's kind of stupid, lmao.

So my partner is getting into brewing beer and I got them a Tilt, which is a Bluetooth hydrometer. It measures specific gravity and temperature, which are things you want to know so that you don't kill your yeast or whatever. Except the sensor's Bluetooth range is super short, and it basically runs via a phone app, and the temperature we're logging currently is the crawlspace, accessible via the staircase closet. So they were like, wait, what do we do about this, because I can't leave my phone in the closet, that's my alarm clock.

In a kind of ridiculous turn of life imitating art, I was like, hold up, I got just the thing right at my desk. Bam. Old phone. We just needed to scrounge up a charger because the battery is so dead that after charging just enough to power on it claimed it was at 53% (to be fair to it, there is a very real chance that it's correct, and it just holds no charge at this point so the capacity is just THAT low) and now it lives in the closet logging sensor data.

And I was like, you know...didn't I just solve a major story detail with a much larger version of this...yeah, no, this is all vaguely familiar somehow, power supply issues and all. Kind of cool that the concept works though. Kind of weird that it came up at all?

We are not gonna talk about the fact that I still have at least two more ancient-ass phones in a drawer where that came from because look, man, sometimes you just need a camera/mic/mini computer with Bluetooth and wifi that fits in a pocket, and people just get rid of these things, but not me. I actually could build a shitty security system out of them if I was reaaaally inclined. I mean. I'm not. But it's technically possible.

For real though, If I pick up any stupid maker projects I still high-key am thinking about slapping Bluetooth into a necomimi headset and running that through an Arduino and learning to code just enough to let me skip songs/change the volume on Spotify with my brain, because it's entirely doable, and I mean yeah I could do that on my phone remotely too, but that's not funny, now, is it. I'm just not sure it's $350+ of parts funny. Kind of a big investment just to prove the point that haha look I am the extremely ADHD type of lazy where I would rather solve a problem via the most convoluted and complicated Rube-Goldberg type ass machine way possible rather than just perform a single simple action.

YEAH I'VE BEEN THIS SCATTERED ALL DAY AND I REALLY SHOULD GO TO BED SHOULDN'T I. I started playing Satisfactory. Mistakes were made. I'm going to dream about conveyor belts again and I did it to myself...

TCS34303 - tri-stimulus color sensor 🔧🌈📸

This weekend, we whipped up a Stemma QT breakout board for the TCS34303 (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TCS34303-OLGA8-LF-T-RDP/7428283) a 'tri-stimulus' color sensor. Most color sensors we've stocked have a red/green/blue/clear diode. This sensor can provide CIE 1931 XYZ output, useful for color correction, or photo/videography. To make it like our old TCS34725 (https://www.adafruit.com/product/1334), we added a white neutral LED. Since it has a 1.8V sensor, we had to add a lot of level shifting to make it compatible with 3 or 5V power and logic. Coming soon.

'Play-putty' that reads the body's electric signals could open a new field of flexible biometric sensors

A new study by University of Massachusetts Amherst researchers demonstrates the effectiveness of homemade play putty at reading brain, heart, muscle and eye activity. Published in Device, the research outlines the conductive properties of this material, so-named "squishy circuits." "[Squishy circuits] are literally child's play putty, that is also conductive," says Dmitry Kireev, assistant professor of biomedical engineering and senior author on the paper. The conductive squishy circuits—whether homemade or store-bought—are made of flour, water, salt, cream of tartar and vegetable oil. "Salt is what makes it conductive," Kireev explains. As a child's toy, this modeling clay is a malleable way to add lights to an art project by connecting them to a power source as a way to teach kids about circuits. Now, Kireev and his team have demonstrated that the material has more potential.
