In the 1960s, fluffy aliens called "Tribbles" found their way onto the original Star Trek series. Characters from the show knew if the Tribbles liked or disliked them by the sounds they made. Andy has a stuffed tribble toy, but it's silent and motionless.
In this episode, Andy builds a new tribble that can react to your presence. Just know that if you're an undercover Klingon, the ear-piercing Tribble screeches will give you away!

![I Put Bluetooth 6.0 Channel Sounding on the nRF54L15 to the Test : Here’s What Actually Happens
Pat Deegan takes a practical look at Bluetooth 6.0 channel sounding using Nordic’s nRF54L15 DK, breaking down how RTT, phase-based ranging, and the new sounding packets behave once you get them off the bench and into the real world. He digs into RF captures, decodes the packets, rewrites the sample code into a cleaner library, and runs open-air distance tests using reflectors, SDR tools, and his own analysis workflows. If you’re curious about how channel sounding actually performs, what the measurements look like at the signal level, or how to start experimenting with the 54-series devices, this deep dive offers a clear view of what’s possible today and where the challenges show up: https://bit.ly/43HfnnM

![I Put AI Inside a Terminator Skull… and It Follows You - Raspberry Pi AI
@MAYERMAKES revisits an earlier animatronic #AI project to see what modern @raspberrypi –based vision hardware can really do in practice. Using today’s AI accelerators and camera technology, he explores how far edge AI vision has progressed, where it still falls short, and what design trade offs emerge when performance, power consumption, heat, and physical mechanics all collide in a real build. Along the way, he works through challenges with model compatibility, motion control, LED feedback, and hardware integration, showing how small design decisions can dramatically affect how lifelike, or unsettling, a vision driven system feels. If you’re interested in building with edge AI, learning from real world limitations, or recreating parts of this project yourself, be sure to visit the element14 Community to access the files, code, and discussion: https://bit.ly/3OEwnGM
