I am building an alarm clock based on esp-32-c3 , mainly it has 7 switches , 1 lcd display , a buzzer and an enclosure to cover the pcb and mount components thts the brief view but here i am using >shift my specific key among the 7 , same like a keyboard , also two alarm specific switches for snooze and stop , thts some normal thing but i pulled this off with only 5 gpios . Also on software side i will be using esp-hal i mean rust unlike standard c++ arduino and esp ide's , as a rustacean thts my duty :D

Great job on this once again! Sorry for making you redesign the whole thing lol. Love how you're using arch and rust. Have fun building it!

This time i added the display , fixed the problematic pcb , wrote the base firmware also made the holes on the bosses to mount the pcb

Finally after the review , completely redesigned the whole thing , made the pcb smaller ,made the 3d box smaller too . Also estimated the price in jlcpcb to get the pcb its hella 3.51$‘s now i think i need to write firmware but before tht i havent made any holes on the cad’s mounting portion(i mean where the pcb and the esp is screwed), after i get it in hannd , i ma gonna do tht manually , it will be more helpful .

Hey, this looks really cool but I need you to make a few changes. Unfortunately your pcb is too large, it should be under 100mm in both directions, this is because going over 100mm increases the price for the pcb a lot. Also make sure you include a .step of your assembly in addition to that freecad file so people without freecad can use your model. Also what's up with those 2 extra buttons, I see you put they'll only be usable when the alarm rings but I don't think those will work at all. I also need you to write some firmware. Thanks!

Finally after a lot of work , i managed to design the cad case , but still i came to know this one has the screw socket size mismatch , i will fix tht and designing stage finished

i removed the resistors that i intended to use for pulling down as i came to see the official guide use the built in ones , i though why me? and removed those , also placed the switches with more precision and estimated the cost will be 10$ , perfect for the given budget now imma gonna do the cad

today i build the schematic and the pcb for init_dawn.d , it took me likely 3hr and 30 minute but due to some lapse problem i cant sync it , anyway i added only 7 physical switches because i dont need 12 , i used 5 gpio pins for the 7 switches , i have a proper idea to control them by using separate mode , 1: Configurable mode
2: Alarm mode
i mean when config mode , the bottom 5 switch will work and when alarm mode only upper two . Also the bottom right is kinda a shift switch , to change +/- for hour and minutes etc , its still a draft but the idea looks clean.
