BrianHG, does Digikey have the Parts package under a specific name ?
jerryk:
I'm suffering from severe excitement.  My boards just came in from PCBWay.

Not really a "I made it", but this is my first attempt at hot air soldering under a microscope.  I think it's easier with just a magnify visor.

I just received the PCBs and getting in enough parts to assemble 2 of them.  You might as well wait till I upload a before/after audio samples on the weekend here on the forum.

If you take a look at my BOM files, the .cvs, tab delimited, scroll to the right and there are 2 different colums, with a 'Digikey' web link.  But, this weekend, on my official project page, I'll add a 'Share-Shopping Cart' link/file from Digikey so you may order, add/remove parts as you like.

My first ever PCB!  Second I have sent for manu, but it arrived first.  The other one got stuck with customs. :(  Have to wait on the bill to get it delivered.

It runs a strip of WS2811 LEDs to make a colourful lamp for my 7 month daughter.



KiCad 3D version:


PCB Layout (there were a few revisions after this like putting the power the right way around!):


Schematic:


Few teething troubles:
* ISP header has the power pins backwards (seems to be a theme)
* ATTiny in SMD format seems to have slower fall times on the data switching, so I needed a 1k botch resistor pull down to force it to fall faster.

But it works.
This is the prototype running:
