Man, i can't believe that someone gives his wisdom for free and does it even better than electronics classes at the university. Thank you very much Sir!
As I'm going binging through your series I am kind of amazed at the production value. You put a lot of work into these videos and it shows. I'm excited for this project (and hopefully for future ones as well!). Thank you!
I think designing your own simple PCB is the best way to learn how to read schematics. There are some good resources on designing PCBs, e.g., have a look at robert feranec and phil's labe. Even if you don't intend to become a hw designer, it's helpful as a software engineer to still go through the pcb design process once.
Hi I had a question. Does the power switch you used take in a variable voltage input and is it rated for DC voltage? I'm having the hardest time trying to source a rocker power switch rated for DC. I saw some illuminated ones rated for 6V DC but that would also unnecessarily complicate the circuit since I'd have to step down the battery voltage from 7.4 to 6V.
I don't remember the part number. But wouldn't surprise me if it's even rated for VAC (for much higher current/voltage than my robot) . It should be fine to use a 250VAC/10A and what not rocker switch in your low DC application as well. It's just a switch after all, the rating is more about the worst it can tolerate.
@@artfulbytes Thanks for the tip! Yeah since the voltage and current levels aren't going to be anywhere near those levels, even if its not slated for DC it shouldn't be a problem. Also, do you have any suggestions for a switch regulator to regulate the voltage from 7.4V to 3.3V? I'm not really sure how to approach this and whether I should buy a chip with external components or buy a converter module.
@@artfulbytes I will be designing the PCB. I thought the process would be to buy the switch regulator and external components and test the circuit first on a protoboard to make sure it works before I design it on a PCB. It'll be the first time I ever design a PCB though so I'm not sure if this is a good approach.
@@NotSionnix @NotSionnix That's generally a good approach. But designing a buck converter with discrete components is a bit cumbersome, and it might just be easier to find design examples online with a switch regulator as an integrated circuit (IC). Many manufacturers provide good schematic/layout examples in their datasheet. One example is AP63203, just needs a couple of surrounding passives. You may look at SparkFun's breakout (babybuck) as a reference.
First time I don't panic in front of a schematic. Thank you for making it so easy and interesting.

It is amazing what u r doing; keep it up! I would appreciate a separate video showing step-by-step how u created the board.
Thanks, yes I hope to cover more step-by-step PCB stuff later on.

Great video! I'm seriously considering buying the parts and try to follow along
Nice, let me know if you do so!
Thanks for this excellent series!!
Awesome work!👏👏
Definitely a great video. Funny to hear you saying that you are a beginner (where am I supposed to be then ?) 😂. Inspiring. Thanks
Haha, yes there are different levels of beginners I suppose. I consider myself a beginner when I compare myself to a professional hardware engineer :)
Great video series! keep it up man
Really great to someone having this good understanding in embedded system how do you learned all of this can you share.
Worked on projects, started small and progressed from there.
Liking the content. Keep it up

Hello there, how would your recommend learning PCB design. Are there some simulators that we can use to learn with ?
Start with a small rroject in KiCad. You can simulate parts of your analog electronics with LTSpice.
Are there any resources you would recommend for learning how to read schematics?

It depends, are you designing a PCB or just assembling loose components/modules?
