Recreating the original Macintosh as a tiny, programmable computer — built in 2021 with a
3D-printed enclosure, plug-and-play AI modules, and a compact 1.54‑inch color screen,
designed so students can understand, modify, and extend it.

<p>
Among the many projects I built while starting my <a href="https://tjtl.persona.co/Startup"
target="_blank" rel="noopener">education technology company</a>, this one remains
a favorite. I worked closely with our mechanical and hardware engineers to bring the project to
life, while leading the overall product experience and software implementation — designing and
building the interaction layer end‑to‑end, from the on‑device UI to
every demo running on it. I also implemented the main system interface that students interact
with: a straightforward menu that lets them browse and run built‑in examples on the
device, or upload custom programs from our companion web app.
</p>
<p>
The device runs on a small color screen and hosts experiences ranging from a classic Mac
screensaver and a Python REPL to a VNC‑powered remote desktop. Beneath the retro
aesthetic, the hardware is genuinely capable — it can run real‑time face tracking,
object detection, and other machine learning models, all on a gadget small enough to hold in
one hand. It was designed so students could understand, modify, and extend it themselves.
</p>
<p>
What I enjoyed most was working at the intersection of design and engineering: rapidly turning
rough ideas into polished, delightful products. The same combination of fast prototyping,
thoughtful craft, and building tools that help people create is what continues to drive my work.

A spectrum visualizer that radiates outward from the center of the display, reacting to
surrounding sound in real time. The module's built‑in microphone captures audio
samples and digitizes them into waveforms rendered on the mini Mac OS interface.

<p>
Plug a camera module into the top slot — like inserting a cartridge on a Game Boy — and
it captures live video at up to 480p. Each raw frame is then run through a pixelization
algorithm that intentionally downsamples and quantizes it into a retro, Game Boy
Camera–style image — a deliberate aesthetic choice, not a hardware constraint.

<div class="demo-desc">
<p>
A multilingual poetry display that cycles through four poems in Chinese, Japanese, and
Korean — rendered using a stripped-down <a href="https://github.com/notofonts/noto-cjk"
target="_blank" rel="noopener">Noto CJK</a> font, compiled into a
bitmap header file and loaded from the micro SD card. An art installation that turns
the tiny screen into a contemplative, cross‑cultural reading experience.
</p>
<p>
When I shared the project on Instagram, a friend reached out — he was part of
the team at <a href="https://3type.cn" target="_blank" rel="noopener">3type</a>, quietly
working on a new pixelized CJK typeface called <a
href="https://3type.cn/fonts/dinkie_bitmap/index.html" target="_blank"
rel="noopener">Dinkie Bitmap</a>. He loved the idea of a tiny device rendering
hand-crafted bitmap glyphs on a 240-pixel screen, so I sent him the gadget to experiment
with. It was a nice reminder that the most unexpected connections come from sharing work
openly.
