Tiny chips. Real circuits. AI that does more than chat.

this wooden desk lets you draw in midair.

watch the pen in the corner. lift it off the table and the orange line on screen rises with it. move your hand in a loop and the computer traces that loop in 3D.

it’s called MagDesk. there’s a small magnet inside the pen and 112 magnetic sensors under the wood.

they track where the pen is and how it tilts.

the pen itself doesn’t even need a battery.

@MagicalTux One cable for a 3.3 V chip and a 5 V sensor. That alone would earn it a spot on my bench

@paz_al3x This is exactly the kind of part I’d spend an hour looking for online before realizing nobody sells it

@Richmonddelmas At 3 a.m., “just follow the yellow cable” is a horror story all by itself

your eyes can't catch every bad solder joint. this tiny camera can

a microscope scans the circuit board while AI checks each joint and highlights possible defects right on the screen, in real time

how it works:
→ a Luxonis OAK4 camera captures the board
→ a computer vision model inspects every joint
→ anything suspicious gets flagged instantly

no squinting, no checking hundreds of connections by hand.

just a microscope, a camera, and a chip that never gets tired

@AlanBin44785396 100% agree, glare was the first thing that broke it. a diffuse dome fixed most of it, shiny joints stop looking like defects when there are no hot spots

your HDMI cable can leak what’s on your screen

watch the laptop on the left. it reconstructs the video playing on the monitor beside it from radio signals leaking out of the HDMI connection

this is TempestSDR. an antenna picks up the leakage, a HackRF radio captures it, and software turns it back into an image

researchers took this further with Deep-TEMPEST, using AI to make recovered images and text easier to read. this clip shows the original technique

quality depends on shielding, distance and interference. the picture is imperfect, but recognizable content still gets through

a wired connection can still leave a wireless trace

@AttackOnChitin I just wanted a laser diode. Why does it think I have enemies?

[Psalter @Psalteric]

@_MG_ @TahaOrsel I cut intro because the most interesting part comes after, and i get credits to Taha. So it's unfair from your perspective

@_Nidouille_ The router is uploading itself to the cloud

@ga0_lab If getting permission takes longer than building, you’re teaching students to stop trying

[Psalter @Psalteric]

@starmexxx A story this specific needs evidence just as specific. But thanks fo sharing

@TahaOrsel I wiil do it

[Psalter @Psalteric]

@sherlock_comms All info is true, idk what do you mean

@i2cjak Thanks for quote, appreciate that

@0xCodez Buying a phone shouldn’t mean letting it choose your next computer
