43oh PCB Logo

it was pickier about the lighting, and getting a good focus, but the 0.1mm solder mask code did scan

 

for those interested in the etching degradation in the copper layer 0.1mm code, here is an image edited together from a bunch of shots through my little microscope , next to the same code in the 0.2mm size

I was able to scan it...

I couldn't scan either etched code, the masked code did scan. I'm using QRdroid at an S2.

Those look really good. It's hard to get an idea of scale from the photos - I assume the ones in the column marked 0.2mm have a pixel size of 0.2mm and the whole QR code is just over 2cm 5mm in size. I'm especially surprised at the resolution of the solder mask.

 

How did the track-style 43oh.com logo turn out? It looked OK on the protoplates I did but I'd imagine it looks much better on a PCB.

 

Coincidentally I was experimenting with home UV curable solder mask over the weekend and managed to get reasonable quality with some simple text. I only tried it because I forgot to engrave the text into the copper.

at 21 pixels wide, with 0.2mm the gross width would be 4.2mm squared! That is, without any padding, let's say we have two pixels padding on each side. Then the entire code would be 5mm squared. The 0.1mm pixel size would come to 2.5mm squared (under 0.1 inches).

Sorry - I appear to be unable to do simple multiplication this morning! @@roadrunner84 is right. I've edited my post above.

I meant the non-etched one.

here is the circuit logo on an actual board (my usb + SD card board)

 

It looks pretty good even though it has some vias cutting into it.

 

I was also piddling around with he QR code, and here is the same data "43oh.com" encoded but with a higher error correction built in, and that let me alter the code to actually say "43oh" as well

 

for those interested, here is the unchanged code.

Added some color. Feel free to criticize. i'd like to make stickers and give them away!

 

1.2.3.4.5.6.7.8.

Looking at it.. 2. looks clowny.

I like #3. The red letters look really good.

Same here #3 or #4

I prefer the single color mostly (cheaper, too).  If you MUST add color, #3 or #4 look best of the bunch.

True. Added red color.

True. Added red color.

LOL - I meant black, but that brings a thought:

Black or white logo on red background?

 

 

White logo on black or 'PCB-green' background?

   

 

I don't much care for the red logo on any background.

Just my $0.02.

 

 

Edited: Added renderings.
