Is this a drone footage? No! It a #DigitalTwin of Hickorywood park, a 3D world reconstructed by using #GaussianSplats using some fancy #AI technologies developed in collaboration with @earthbytelab.bsky.social It's now a world with colliders that one can walk through like a video game.

One of the reasons I cancelled my Oura membership is the cloud dependency, someone deciphered the BLE protocol: github.com/Th0rgal/open... My past weekend project: based on this protocol, I was able to build a macOS app that does data ingestion locally from my Oura ring... on to some ML training!

Sure, here’s what it ended up as. TrueNAS scale offline backup of my home TrueNAS scale.

I’m on iOS 26 beta 2, let me say that I’m really happy with CarPlay Apple Maps changes, especially the time and distance remaining info. I missed these on the current iOS, always had to use Google maps instead.

The home Whirlpool fridge LED was flickering for the past week, Whirlpool wanted $115 to replace (part# W11527432), instead I replaced 8 LEDs (2.45V forward voltage) in series for a whopping total of $2.03 from DigiKey! Years more of 💡

Congratulations to Rafael & team to get one of the most advanced 1.2 GHz NMR spectrometer (first in North America), thanks to funding by NSF (ie tax payers). Thoroughly enjoyed every talk & poster at the 9th Gateway NMR conference (u.osu.edu/gatewaynmr/) #nmrchat

Ok some success, I pressed the DTF transfer using a hand iron (155C) onto a PLA sheet like a garment. Transfer worked, but the PLA melted a bit!

It’s very interesting topic of RNG, it’s always fascinated me how random numbers are generated. My favorite microcontroller - ESP32 chips use ADC noise for random number generation:

#NMRChat blown fuses on BCU-I

Deb Sahu @debashishsahu.com · 25/03/2025
I was updating @brukercorporation.bsky.social topspin to v4.5.0 and BCU-I dropped off the BSMS after the upgrade. It was just a coincidence that fuses blew on the BCU-I at the same time, now got to figure out what caused the fuses to blow!

If anyone is looking for the chip, it’s XY805A following this schematic on its data-sheet. I used a 44uH inductor for ~40mA constant current for LED illumination. Inductor is needed as forward voltage of cold-white LED is higher than 1.2V supplied by battery.
