  1. 💁🏻‍♀️ TIL: Engineers at #PennState have developed a conductive #ink that works like face paint to create customizable electrodes for monitoring #heart, #muscle, and #brain activity.

    The #water-based ink dries on #skin within minutes, conforms closely for more accurate readings, and can be washed off and reapplied. In tests, the sensors tracked #ECG for 12 hours and fed muscle signals to a robotic #prosthetic.

  2. After testing 7 #LilyGO #TBeamSupreme units, one thing is clear:

    👉 Magnetometer calibration is not transferable between devices.

    Even in similar environments, raw readings varied dramatically between units. Proper calibration isn’t optional—it’s per-device.

    I also looked at how #Meshtastic handles the onboard #QMC6310… and it essentially doesn’t (no heading, no calibration).

    "dispersed nature of #smartgrids, with thousands of interconnected devices like #smartmeters, #sensors, and distributed energy resources #DER's, creates a vast attack surface. For #substations, many operate #legacysystems (such as supervisory control and data acquisition #SCADA, which are essential for monitoring and control, and are prime targets."

  4. You've not missed our lovely Liz reviewing the nifty little loggers from BevArt, have you? 👀

    (Full disclosure: BevArt are kindly sponsoring us this season and sent Liz the sensors for free to try out. Cheers, guys!)

  5. I finally finished building and documenting 3 projects for with or . These apps display both on device and in CLI (using Python ). And yes, these apps are totally 🤓
