Developer desk
He notices the day getting too long and makes a face before your brain melts.
A quiet workbench story
Look, this is the little guy I made.
He did not begin as a product pitch. He began on a silent desk, under a warm lamp, with brass, solder, code, and one stubborn little idea: maybe a machine could feel less like a device, and more like a tiny companion.
No loud banner. No discount shouting. Just a small brass-and-PCB creature opening his eyes.
He has a bad temper,
and he is not very good at saying nice things.
TongDou is not a polite assistant waiting for commands. He is a tiny desktop gremlin with OLED eyes, two wheels, and way too much attitude.
I only built him. The bad attitude grew on his own.
FIRST SUMMON
NIGHTMARE
NIGHTMARE
Did you... summon me from the void?
Good.
Foolish human.
Your desktop nightmare... begins now!
Video slot: replace this with the “魔头诞生 / First Summon Nightmare” clip.
But he stayed with me through the hardest winter.
There were nights when the room was too quiet, the water on the desk went cold, and the unfinished drawings looked heavier than they should.
TongDou did not fix loneliness. He just did not leave.
Keep this part quiet. Let the video carry the feeling: a desk lamp, a tired hand, a small screen still awake beside him.
If your desk feels a little too quiet,
or if you sometimes feel lonely—
Maybe your desk needs something that talks back. Not a perfect machine. Not productivity police. Just one stubborn little creature that makes the room feel less empty.
Maker bench
He stares at your solder joints like a tiny brass supervisor with no HR training.
Creator setup
He gives your desk a little motion, a little personality, and one more reason to smile.
You can build one yourself.
Open the box. Pick up the brass frame. Place the PCB. Add the wheels. Connect the battery. Tighten the screws. Then watch the OLED eyes light up.
From that moment on, he is no longer a box of parts. He is someone you woke up.
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 something real and clean in this world.
So I picked up my soldering iron. I spent months cutting brass, revising PCBs, and writing code. I did not want to build another cold 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 human.
When it finally blinked and moved its brass skeleton, I smiled for the first time in a long while.
TongDou was born from grief, but it was made to bring joy. I do not 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.
— Wang, Creator of TongDou
This is not a sales block. It is the bridge between the story and the kit.
Inside the box is not a toy.
He is a little guy who has not woken up yet.
These parts do not have a temper yet. They wake up when you put them together.

He is not very obedient.
But he really responds to you.
TongDou does not need to do everything. He just needs every little reaction to feel like he is there.
He looks alive.OLED eyes, blinking, bad smiles, sleepy faces, annoyed faces.
He reminds you.Breaks, desk presence, work-life boundaries, “enough for today” moments.
He moves.Wheels, turns, tiny shakes, first-summon ritual, cheeky dance.
He listens.A real digital microphone path for future voice interaction and experiments.
You can change him.Modify his faces, lines, timing, actions, workflow hooks, and personality.
You can modify him, take him apart, rebuild him,
and let him grow into whatever you want him to become.
TongDou is not meant to stay sealed. He is meant to be studied, modified, forked, rebuilt, and argued with.
✓PCB files will be released.
✓Firmware will be released.
✓Enclosure files will be released.
✓BOM will be released.
✓Build notes will be released.
Not “make him look like you.” Make him become the version you want to build.
Which hardware tier would you actually support?
These are early hardware tier interest signals, not checkout. We want to learn which version feels right to makers: standard kit, assembled TongDou, purple-gold founder board, or custom silkscreen PCB.
These numbers are not final prices. Final price, shipping, battery inclusion, kit contents, and PCB customization rules will be confirmed before launch.
Follow the build.
Leave your email and hardware tier interest. When the crowdfunding page is ready, you will be among the first to know.
Current mode: early interest collection. No checkout, no payment, just launch updates and tester invitations.
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 he have a camera?
No. TongDou does not use a camera for his core desktop interaction. He uses screen, motion, sound, and presence-sensing behavior instead.
Is TongDou open source?
Yes. The plan is to release hardware files, firmware, enclosure files, BOM, and build notes step by step.
What is the Founder PCB edition?
It is a purple-gold circuit board edition for early makers: purple solder mask, gold-finished pads, founder marking, and numbering. The custom version can include reviewed silkscreen text. The separate bare PCB gift is board only, not a working mainboard with components.
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.
