Chichi

Hi, this is a cute chicken lamp, I call it Chichi. It runs on an ESP32-C3 with 2 WS2812B LEDs, and 1 slap triggers a color change while 2 slaps toggle the lamp’s power.

You don't have the pcb cart screenshot! Additionally, you cannot ask for funding for fillament :(

One final thing! You need to make a BOM.csv in your repo, which will have all the parts that you use & their prices.

Please looks for alternatives to amazon, as they are the retailer that usually has the most expensive parts. Look on sites like alibaba or temu!

Reduced the PCB size and updated materials & BOM

The LiPo battery wouldn't be able to provide a stable 5V to esp32, so I added a new module MT3608 Boost Converter for stable 5V. Updated my PCB as well! Also, I added price and link to modules in my BOM. I discovered that shipping is making this costly!!! Might have to update my tier.

The new PCB:

most of them are external modules, so i need not worry about the PCB size, it should fit inside the shell, at printing legion, i found someone who can print my model for just $5(thats rlly good including shipping) and PCB using JCLPCB can be easily made under $10!

waiting for approval finally

Your BOM is missing prices and links! Also add it as a CSV to the main repo

Updated PCB and 3d Model

I figured out a way to fit the pcb in this compact 3d model, turns out I was just doing wrong. I remove the huge symbols of piezo electric plate and LiPo battery and made smaller symbols.

also, while reviewing my design, @Iamalive asked for the original mode, its:

there. I didnt make much edits but i added a cylinder between its neck and hollowed out, so i can fit my PCB inside. They also asked for final render of PCB which is:

that's it!

Can you include an image of the original online model of the lamp you found, so we can see how much you've changed? Additionally please include an image of the final render of the pcb!

Made KiCAD PCB and Schematic!

I made the Schematic of this lamp using KiCAD, the symbols were really harder to get so i used custom footprint and symbol for LiPo battery piezo electric plate. Finally, routed the PCB and pushed to github! ABout to submit.

this lamp works such that, it glows using 2 WS2812B addressable LEDs, its kinda funny, but i used piezoelectric plate to detect slap. One slap on back is change color, two quick slaps is Power On/Off. I didnt find any suitable controller, so i decided to use esp32 c3 mini which is of very well size for my use case. and Rechargable battery so it need not stay plugged.

I have to find the parts online now and then I'll proceed with design Submission yay!

DEVELOPED A 3D MODEL OF THE LAMP

I USED FUSION360 TO RENDER A 3D MODEL OF THE LAMP, I FIRST TRIED MAKING MYSELF, BUT THEN I FOUND A REALLY WELL MODEL ON WEB, SO I MAYBE DROPPED MINE AND TOOK THEIRS, THO I MADE EDITS TO IT.

MY MODEL:
chichiii

THE ONE I FOUND:
chichii
