Building a $40 Stingray Detector That Fits in an Altoids Tin

You don’t see IMSI catchers. You don’t hear them. They sit between your phone and the network like a polite lie, impersonating a tower just well enough that your device shrugs and connects anyway. No warning. No vibration. Nothing in the UI suggests that your phone has just been convinced to trust something it never verified.

Any European sell some mid to insane level soldering training pcb? or know shops that ship from within EU that does?

Trying to avoid charge pumps for a negative rail means constantly tripping on diode drops and paying 10x for R2R opamps.

Not sure why I decided to "die" (go mad and/or broke) on that hill.

I'm alive again. Let's go!

This feels like some sort of crossover episode with a version of myself I thought died a long time ago.

I am alive, right this very moment, and live on twitch working on my little project of a virtual pet, all while listening to some chiptune BANGERS and doing my best to understand the notes a very burnt-out, frustrated patch left himself nearly a year ago.

Come say hi!

How We Built a Norns Shield: https://gnd.buzz/blog/build-norns-shield

New blog post. Not sure if it's useful to anyone but future me or people interested in SMD assembly using a reflow oven :)

If you are in Berlin and would like to build one as well, do reach out. Might make it a workshop.

Shout-out to @viernullvier for all the help and @xHain_hackspace for hosting 🖤

Patch Arcana Apr 6

Just a short little #blog update today - with all the good news going on around here, and the usual springtime rush of fresh energy, I'm going to be resuming work on #PETI, the homebrew #VirtualPet I started work on back in 2019.

There's just one itty bitty problem: the development branch is about six months stale and I have no sweet clue what the hell I was up to from back then.

I will be disentangling that during lab hours on my twitch channel tomorrow.
