im locking in polish today

this bout to be the most polished thing ever

first things first, delete whatever i made b4

start w blank slate

okay, time to design a logo

will use Figma

o, r, p, h all layered on top of each other

v2 of logo

need to add 32 component to it

bruh ts is so hard

idk ill start afresh

ok im back at 3:45 pm

time to get back to work on this

ok that looks better

ok who let me cook

something needs to be in the middle

also got tons of positive feedback which is nice to hear

who let me cook

something forming?

i feel like this is enough

ahhhhhh

im trying to make it better

i tried to brand it as “the most comical devboard” but it did not end up working

i need to find a way to make this more personalized

ahhhh why is this so hard

project rejected :(

apparently it is too generic in terms of art

need to fix that!

looking at https://hardware.hackclub.com/gallery for inspo

i like https://github.com/NotARoomba/ember and Taranium-RP2040

made it comic sans

ahhhhh idk how to make the art better

redoing all the passives

going to change placement as well

some changes to values + decoupling caps added

done with pairs + placement!

wowoowowowow

time to see price bc i lessened number of items

bruh price is $93 now

$180 w customs and shipping 😢

I HAVE TO RESTART bc ESP32-S3 is too expensive

luckily i have rev2 still available which uses

routing time

wait ill add SK6218-mini

ok added

PCB done! need to add silkscreen now!

both sides done!

time to add Hack Club logo

BOOM!

ok sent message in slack

idk i feel like accelorometer is not needed

i think i might prepare for submission now

ok going to prepare for submission

added cool labels to evrything

creating render cause why not

Render

PCB + Schematic

KiCAD Render

JLC comes out to $40.30 👀

ok time to upload files and prepare README

I fixed DRC errors that Taran pointed out

now i want to add a neopixel to make it look cooler

going to use SK6812 cause why not

routed it!

will add 3d model

ok added it from SnapEDA

wait the headers are reversed; need to fix

time for silkscreen

raygen wants me to add another neopixel

was not planning to, but sure

added!

going to view other devboards

notes from other breadboards:

• label schematic to make it pretty
• label pins (seems to be very important)
• hack club logo + other silkscreen art

ok im locked in now

wow this is harder than I expected

first half done! one more half to go

had a bunch of problems choosing font and positioning properly

made post on Hack Club Slack

ok i think thats it for now; will come back to fix problems, tidy schematic, and prepare to submit!

seems like no major errors as nobody has said much on Slack

Taran told me to add which GPIO are being used for sensors, so I did that!

going to create order on JLC and source parts!

im doing everything except the pins cause i don’t really need them PCBA

ok i can do a lot of optimization

but first, i need to fix all the things Rudy mentioned

ahhh too tired for this; will do tmrw ig

@Rudy on Slack told me to use a ESP32 with built-in UART-to-USB

ig thats what we are doing for this

after brief research, I found ESP32-S3-WROOM-1 with 36 GPIO

will read https://documentation.espressif.com/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf

idk if I even should create a board bc its going to be super basic

copied USB-C w/o diode

going to use same power circuitry

added buttons

bruh my schematic feels so basic

pcb also feels too basic… idk if this is worth it cause its too basic

ok im back after a couple of hours

i’m going to make this a sensor board

finally mastered differential pairs in KiCad w https://www.youtube.com/watch?v=M13QxtPVrXY!

wait routing this is impossible

waiting for expert resposne in Slack; going to select some chips to use

after brief research, i’ve decided to use BME280 and LSM6DS3

BME280 is temperature, while the LSM6DS3 is accelorometer

after much reading of datasheets, came up with this! hopefully it is correct

rev 3 is complete!

time to fix everything I did wrong, such as:

also apparently my routing is inefficient

REROUTED EVERYTHING AGAIN BUT IT STILL DIDN”T WORK

AHHHHH

time to watch https://www.youtube.com/watch?v=KgOQaBUPiBo

ok that vid no good lets try https://www.youtube.com/watch?v=v2okbB05piE

AI slop vid; nvm lets try https://www.youtube.com/watch?v=0tuuMSxcVxg

got it working!

w render

and we are done with routing for rev2… wow this is turning out great! next rev, need to minimize vias from 15 to like 5
