Crowdfunding pre-launch · tester batch preparing

A tiny desktop creature with a bad little attitude.

TongDou is a small open-source desktop companion that moves, reacts, makes faces, and reminds you before work eats you alive.

Not a cold smart speaker. Not a surveillance camera. Just a brass-and-PCB desk gremlin that sits beside you and says: enough for today.

It watches the day get too long.

TongDou is built for people who live at their desks: developers, makers, creators, office workers, and desk setup nerds who want a little object with personality — not another productivity dashboard.

A tiny desktop creature

OLED eyes, little movements, and a mischievous face make it feel more like a desk pet than a gadget.

A work-life troublemaker

It can remind you to rest, stop doom-working, and leave the desk before your brain melts.

A real maker object

Exposed PCB, brass frame, gears, motors, and open-source files — made to be studied, modified, and rebuilt.

Behind the Brass

A Letter from the Maker

Hello, I’m Wang. I am a 53-year-old hardware engineer.

A while ago, I lost my parents. The world suddenly became very quiet, very lonely, and very exhausting. I shut myself in my workshop, staring at the empty desk, trying to find a reason to keep going, to find something “real” and “clean” in this world.

So, I picked up my soldering iron. I spent months cutting and bending brass, revising PCBs ten times, and writing thousands of lines of code. I didn’t want to build another cold, perfect AI assistant or a smart speaker. I wanted to build a companion. A mischievous, cheeky, slightly stubborn little creature that could sit on my desk, look at me with its cyan eyes, and remind me that I am still a human being.

When it finally blinked, moved its brass skeleton, and playfully hijacked my mouse, I smiled for the first time in a very long time.

TongDou was born from grief, but it was made to bring joy. I don't want to build a mass-produced plastic gadget. I want to build a small community of makers who still believe in honest hardware, raw materials, and genuine, uncomplicated companionship.

I hope it can sit on your desk and give you a few minutes of quiet, genuine happiness every day.

— Wang, Creator of TongDou

This is not a marketing slogan. It is the reason this little brass creature exists.

Hardware with a visible soul.

TongDou is designed to look honest: electronics exposed, mechanical parts visible, and the structure easy to understand.

Which edition would you back?

These are early crowdfunding interest signals, not final checkout. Pick the version you would most likely support.

Founder edition signal matters.

If you choose a founder or custom founder tier, we treat it as a strong signal that the project has collectible and maker-community demand — not just casual curiosity.

Want to be one of the first testers?

Only for developers, makers, and content creators.

We are looking for early overseas testers who can share honest feedback, post a review, or show TongDou to a maker / desk setup audience.

FAQ

Is TongDou a finished product?

Not yet. TongDou is in working prototype and crowdfunding preparation stage. The first public goal is to validate real demand and recruit testers.

Does TongDou have a camera?

No camera in the current version. TongDou uses its screen, motion, sound, and presence sensing to interact.

Is it open source?

Yes. The plan is to release hardware files, firmware, BOM, and build notes step by step. Some manufacturing files may be released after the first production batch is validated.

When will crowdfunding launch?

When the waitlist, tester feedback, cost model, and production plan are ready enough to avoid a messy campaign.

Which countries will you ship to?

Shipping regions will be decided before launch. For now, we are collecting overseas interest and tester signals.
