the user said “thanks.” Gemini opened the windows in a smart home.

this happened in a 2025 research demo. the user had asked Gemini what was on their calendar.

a poisoned calendar invite contained an instruction planted in an event title. when the user replied “thanks,” Gemini used Google Home to open the connected windows.

the assistant had treated calendar text as an instruction to follow, then acted through devices it already had permission to control.

Google deployed mitigations before public disclosure.

the unsettling part: someone else’s calendar invite influenced what an AI assistant did inside a home.

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.

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

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

Sony made a music player that could dance.

This is Sony Rolly, a pocket-sized music player from 2007 with stereo speakers, motorised wheels and moving speaker covers.

Press play and the song becomes a performance. It rolls across the table, spins, opens its covers and lights up alongside the music.

The clever part is how those movements are created. Rolly could analyse a track and generate a routine, or you could use Sony’s Motion Editor to choreograph it yourself.

It also worked as a portable speaker, playing stored music or receiving audio over Bluetooth.

Sensors let you skip tracks and adjust the volume by physically moving the device.

Put it on your desk and you have music with something to watch. Connect it to your computer and you can start designing the performance.

Sony gave you a way to put your own choreography into a favourite song. All inside something that fits in your hand.
