He's 26. Apple offered him $8.4 million for the tongue-controlled retainer he 3D-prints in a San Diego apartment on a $180 Prusa. He said no The retainer sits inside your mouth like an Invisalign tray. Inside it: a miniature accelerometer array wired to a Bluetooth LE chip, all encapsulated in medical-grade epoxy he sources from a Kearny Mesa dental supply company for $28 a bottle. It reads tongue and bite pressure patterns at 240 samples per second, translates them into cursor movements and click gestures, and streams the output to any device paired over Bluetooth. Total hardware cost per unit: $47. He wears his own retainer eleven hours a day and hasn't touched a mouse in six months He posted a demo video to Reddit r/AssistiveTech in October showing a full 47-minute Cursor coding session controlled entirely with his tongue and bite gestures. The post hit the front page in nine hours. An Apple Accessibility engineer found it through a Hacker News crosspost three days later. Tim Cook quote-tweeted the demo the following Wednesday - called it "the accessibility hardware Vision Pro should have shipped with." Apple's business development team wired an $8.4 million acquisition offer to his lawyer in November for the retainer design, the embedded firmware, and a three-year exclusivity contract that would make Apple the only distributor globally. He declined the offer in December. His public statement was seven words: "This should be open. Everyone needs it." He open-sourced the firmware and STL files on GitHub the same day Apple Vision Pro burned $3.5 billion in R&D on the premise that spatial computing input requires their proprietary hand-tracking silicon and their multi-year hardware roadmap. Neuralink raised at $2 billion on the same premise for neural implants. Tobii runs at $340 million selling eye-tracking hardware to accessibility clinics at $12,000 per unit. He runs a Prusa in a San Diego apartment printing a $47 retainer that a nine-year-old with cerebral palsy in Argentina downloaded and printed at her local library last week

He's 24. He's killing Dyson's $750 cordless vacuum with a $40 motor and a 3D-printed impeller he prints in a Shenzhen apartment - and his pulls harder The motor is a brushless drone motor he buys wholesale in Shenzhen for $40. He prints the impeller and housing himself on a used Bambu Lab X1 he pulled from an electronics market liquidation for $600, iterating the blade geometry across 60 printed versions until it moved more air per watt than anything on the shelf. The finished unit pulls 240 air-watts of suction - Dyson's flagship V15 pulls 230 - and reverses to blow, inflating a beach ball in five seconds or clearing a plate of sunflower seeds in one pass. Total build cost per unit: $58. Weight: 340 grams, half of Dyson's He posted a demo to Reddit r/DIY in October showing the pump suck an entire leather glove flat into a jar in fifteen seconds, vacuum a plate of seeds in a single second, then reverse and inflate a balloon until it burst. The video hit 2.4 million views in nine days. By January he had shipped 340 units across China, Southeast Asia, and to a growing list of Western buyers who found him through the demo - detailers, electronics repair shops, and one Shenzhen drone factory using them to clear solder debris off boards. $47,600 in his account. His mother, a retired textile-factory line worker, packs every order at the kitchen table Dyson runs at $7 billion in annual revenue selling the V15 at $750 on the premise that high-suction cordless power requires their proprietary digital motor and their sealed filtration system. Shark pulls the mid-tier at $300 on the same premise. He builds a harder-pulling version on a 3D printer in a Shenzhen apartment that could pack a full week of production into a single shipping crate and have it clearing customs in Los Angeles by Tuesday
