Do more pcb stuff 👍

I hoped you would say that! 🤓

Just a tip from a fellow newbie. If you use one layer as ground and the other(assuming a two layer board) as power you get rid of a lot of power and ground routing. Nice and useful project!

[@DeveloperDIY]

Thanks, I was thinking of a ground layer but I didn’t want to over complicate my first attempt. I’m also conscious that the PCB will be mounted to a 500 degree oven and will probably be exposed to temperatures up to 60 degrees so having less copper might help with cooling.

[@philippeschjelderup9644]

@@DeveloperDIY I would say having more copper would be better for heat dissipation, and it will help the pcb stability shape wise. And if the card will have more heat exposed to it, I would make room for mounting a heat sink.

@@philippeschjelderup9644 I suspect you are correct. I wasn’t happy with the rectangular case, I think version 4 will have a round case which will suit the shape of the oven dome better. I’m also keen to redesign the board to hold the ESP32 chip and voltage circuits directly so I don’t have to use a dev kit. This will make the whole PCB smaller too. All useful tips are welcome, there is so much to learn.

@@DeveloperDIY I think that is wise. I also design my boards with SMD components, have made multiple circuits with ESP32-S2 and ESP32-C6(Zigbee version). My latest Automatic Watering System for my kitchen garden is currenly under testing... I have to upgrade to S3 since S2 is obsolete. I will go for ESP32-S3-WROOM-1-N4.

@@philippeschjelderup9644 an automated watering system sounds like a great project, do you make videos or articles about your projects? Also using Zigbee sounds great too. Does the Zigbee connection work with Home Assistant well?

This was great, thoroughly enjoyed watching from start to finish. Appreciate you sharing the mistakes and your process in adapting along the way.

[@DeveloperDIY]

Thank you, it’s difficult to judge how much detail to put in without it getting boring. I’m glad you enjoyed it.

@@DeveloperDIY As a fellow creator, I understand the pressure to deliver value without wasting time. I often worry about boring people with technical details, but your video was engaging from start to finish. It reminded me that the right audience values genuine connection over perfection. Thank you for the inspiration!

[@jeroenrevalk]

Are you gonna use al the recieved boards? Asking for a friend ;)

[@DeveloperDIY]

I’ll swop you for some of your pulled pork! 😋 that looks amazing!

KiCAD is afaik free for any purpose

[@DeveloperDIY]

You are absolutely right. This was my first dive into EDA software and PCB design so there was much to learn. I’ve since learned that KiCad is open source and has a great community dedicated to its growth. I’m excited to learn more about KiCad and PCB design in general. Hopefully, as my knowledge grows I’ll do a few more videos.
