Day-3

Gonna work on Schematics

ToDo

• Add esp32-c3, shift registers

Devlog

I started by opening the kicad and working by adding the battery – but the kicad isn’t working properly (Some technical issues)

So, I switched the work to just sketch the rough idea about the led cube

I drew simple drawing showing the connection of the led’s – Cathodes should be joint together on both horizontal and vertical..!

The anode should bent with 90 degree and must be symmetrical

After the rough sketch, i moved on to add the schematics

I also sourced product for the esp32-c3 and found one by the manufacture – seeed studio

I used chatGPT to analyse some of the sourced products for the project.

That’s all for today

What’s done

• Added Battery, esp32-c3, Shift registers header into the schematics
• Sourced esp32-c3 and shift registers from digikey india

Day 2

Actually, i found some pcb boards online for this project
But i’m not gonna copy them – just for some inspo!!

Todo

• Layout the schematic (Before that decide about using Shift register or not)

Devlog

I was kinda confused because the online gerber files doesn’t include the shift register – idk the reason
So, i asked GPT to clarify that doubt!!

They are not using Shift registers because the cube is 4x4x4 and doesn’t need a lot of pins

We will jump into the Schematic diagram – and simultaneously add components in BOM

We will be using TP4056 module for charging but kicad doesn’t have built-in for it

Day 1

I just figured out that i couldn’t commit – when i just create a folder with no files inside it.
I was like fighting against it for 10 mins..!!

Description

Let me be clear with what i am building

I’m building a 5x5x5 led cube with battery built=in.

• It got 125 leds(Blue color) arranged in 5x5x5 – I’m gonna design two types of PCB one for base and another for layers
• It got battery built-in, so it can be brought anywhere
• It will have case for the bottom and i’m thinking for a case on top too.
• The code can also be easilt uploaded using USB in the bottom case

Todo

• Search for components and prepare BOM
• Import components into the Schematic diagram

Devlog

Let’s get started..!!

I’m searching through online for components.

Finally, i found source for Blue led It is diffused because it emits light all around and making it visible from any POV.

I also found a instructable tutorial – link

It’s actually getting one hour already – I’m gonna get my lunch…!!

Work done

• Found led and also a gold tutorial (Hehehe, i would refer it to finish this project)
• Learned a lot about leds (Diffused, clear – 5mm, 3mm and more..)
• Also, i got some idea about shift registers and why we use that here.
