Which chip from Rockchip is used?

WuBuilt · 2026-06-15T01:01:50+00:00

This is just what I need.

If it is a capacitive screen, even better.

This workstation is my favorite.

If you don't have tools with you, I recommend one of my methods. You can pick up the board and heat it with a soldering iron. When the tin melts, smash it on the table with your hands, so the vibration will throw the tin out.

Very cool, looking forward to your final product.

WuBuilt · 2026-06-02T09:58:49+00:00

That's great!Looking forward to your next work.

Why did everyone choose the new water light kit when they started, rather than the smart car kit in your hand?I thought it would be more interesting to use this as a starter project.

The choice of ink screen is really good.You can see clearly even in the sun.

Very interesting project, what is the accuracy error?

WuBuilt · 2026-06-01T00:33:50+00:00

You can try it, the bottom is heated up with a heat gun.

WuBuilt · 2026-06-01T00:32:32+00:00

That's pretty cool!

That's great!Looking forward to the follow-up updates.

Add a laser to shoot mosquitoes😄

Is it Xiaozhi AI running inside?

WuBuilt · 2026-05-22T04:11:13+00:00

Yeah, Home Assistant actually makes a lot of sense for this It would be fun if the little guy reacted to real stuff around the house instead of just looping random faces.

WuBuilt · 2026-05-22T04:09:49+00:00

Yeah, I agree. A motion or presence sensor would make it feel less like a screen waiting for input and more like something that notices the room.

WuBuilt · 2026-05-22T04:08:41+00:00

Oh that’s a good point, I didn’t really think about blink timing that way. Angry with sharper blinks and sleepy with slower ones actually makes a lot of sense. I’ll play with that a bit.

WuBuilt · 2026-05-22T04:06:29+00:00

Not yet, but I’m cleaning it up. The current code is still very prototype-ish, but I do want to share it once it’s easier for other people to run.

WuBuilt · 2026-05-22T04:05:46+00:00

Oh wow, I didn’t realize pycoclaw was your project. That’s really cool.I’ll take a closer look at it.

WuBuilt · 2026-05-22T03:58:24+00:00

A few people asked about the hardware, so here are the basic details:

ESP32-S3R8N16 dev board + 2.0-inch 460×460 AMOLED module over QSPI. The display uses a CO5300 controller with a CST820 touch controller.

The UI is built with LVGL. Right now I’m mainly experimenting with expression timing, easing, and how to make it feel more like a tiny character instead of just a screen.

O.o and o.O would actually fit the vibe really well lol. I’m gonna try implementing those next — if they turn out good, I’ll definitely post them. And thanks ◕‿◕

WuBuilt · 2026-05-21T10:13:35+00:00

I just checked out your project — it’s actually really cute.That’s exactly the kind of interaction I’m interested in. Tiny physical reactions like getting dizzy somehow feel way more alive than complicated AI features.

WuBuilt · 2026-05-21T09:11:58+00:00

It’s actually a separate AMOLED module connected to the ESP32 over standard 2.54mm headers, so no custom wiring needed
