Enterprise playing cards could also be outdated in right now’s digital world; nonetheless, there may be nonetheless no faster solution to give somebody your contact info when assembly in particular person, so they don’t seem to be prone to go away any time quickly. That doesn’t imply that technophiles are content material to reside with fifteenth-century know-how, nonetheless. A well-liked pattern amongst {hardware} engineers is to construct customized printed circuit boards (PCBs) that function enterprise playing cards — solely far more fascinating. We’ve got seen examples that simulate the movement of a liquid or play the snake sport, as an illustration.
Now, YouTuber Construct With Binh has taken boring outdated enterprise playing cards to the subsequent degree with a PCB that runs a big language mannequin (LLM) totally on-device. With its distinctive theme, it’s positive to be a success at Halloween events this Fall. Known as the Bouija card (a mash-up of “Binh” and “Ouija”), it has an eerie consumer interface coated with LEDs that blink out messages from the poor laptop algorithm that’s perpetually locked away contained in the board’s silicon.

The Bouija card PCB is populated with an ESP32-S3 microcontroller with 8MB of PSRAM and 16MB of flash reminiscence, a USB-C charging circuit for energy, capacitive contact pads, and a bunch of LEDs. 40 LEDs in whole had been included — one for every letter and quantity, and some for particular functions.
So far as the firmware is worried, a lot of the work was already performed. Construct With Binh relied on the library beforehand created by Dave Bennett that makes it potential to run a small LLM educated with the TinyStories dataset on ESP32-S3 microcontrollers. This mannequin comprises 260,000 parameters and it might solely generate small and easy tales, so it’s nothing like carrying ChatGPT round in your pocket, however it’s an fascinating novelty all the identical.
After integrating the prevailing library with the capacitive contact sensors and LEDs of the Bouija card, Construct With Binh had a really distinctive, and spooky machine. It might blink out the textual content of quick tales on demand, and it really works fairly properly. Assessments revealed that the ESP32 chip can churn by way of about 24 tokens per second. Not unhealthy in any respect.
Construct With Binh’s enterprise card is an affordable solution to impress potential employers or purchasers, entertain your self, and spook your mates this Halloween, so why not make your personal? In case you are sport, there are many particulars out there on GitHub to get you on the appropriate path.
