What is the viability of a newbie being able to design this?
« on: January 15, 2017, 09:08:43 pm »
So I have this project where I need to design a PCB for a project.

The designed is centred around a Arduino "ATmega328" and a couple 7 segment displays.
I need to still have the USB part to program the micro controller.
Will also need a lithium battery charger and a secondary input that is between 10-20v to power the whole thing.

While I would love to just hand this off to someone, I don't really have the budget to do that so I am looking to design and get the PCBs made and components fitted on a run of around 50 units.


I have been watching Dave's older videos on doing this and feel like it is possibly something I could do myself?
Not really used circuit design software before. I have had a tinkle in CircuitMaker but it is a tad daunting looking at how much there is.
I am guessing it is best done in baby steps?
Tare apart the Arduino design and then design the drop down converter, then the charging circuitry.

Thinking it would be best to look at stuff already made, like those charging circuits you can get off eBay and reverse engineer them into my design?
(If that is allowed? Guessing most of these things are just straight off the PDF you get from the manufacture so no real problems there?)


What my question is here, is if this is at all viable for someone just starting out.

Thanks
Jack,

I think you should find all arduino ready modules that fits your need.
program it, discover how they work. make one protptype with ready made small boards, and breadboards.
then, once it works, ( one big step for you) you can go to the next step: make your own pcb with only what you need on it.
if you need 50 working units, better make one working first.


also if you are stuck on a problem, I'm sure you will get help by coming on this forum and explaining it.

On a similar vein is a reply in this thread along with some links to other PCB software:

Already got a prototype working using the Arduino Nano board. Though I have yet to program buttons or the wifi.
My main problem is the power stuff. I am guessing there are open designs out there that people share that one could use?
Or is it just a case of search though the forums as I am sure others have posted something similar.

I remember doing this is school years ago xD
Probably give it a go while I wait for PCB manufacture to make a test one and ship it.


Thanks guys!
