Reading between the Gerbers
10/24/2018 at 06:30 • 0 commentsThe "outputs" of what looks like the production version of the PCB's for both badge and expansion were posted to the official badge project, the zips contain a sub-folder with gerber files.
In the process of converting the gerber files into a KiCad board file, you will get the following layers doing "Open Gerber Files...". Note that these leaves out a number of layers that use other file extensions naming conventions. The "Outline file was manually imported by selecting the "*.*" file type option.
- *.GBL (Bottom Layer / B.Cu)
- *.GBO (Bottom Overlay / B.SilkS)
- *.GBP (Bottom Paste / B.Paste)
- *.GBS (Bottom Solder Resist / B.Mask)
- *.GTL (Top Layer / F.Cu)
- *.GTO (Top Overlay / F.SilkS)
- *.GTP (Top Paste / F.Paste)
- *.GTS (Top Solder Resist / F.Mask)
- *.Outline (Border / Edge.Cuts)
The mapping to KiCad layer names is shown after the Gerber convention. This comes in hand when using the Export to Pcbnew from Gerber viewer.
Also note that for whatever reason when I converted the *.Outline to Edge.Cuts, I got a duplicate outline of one on top of the other, which just caused the laser cutter to cut the same path twice. -
Image interperlations
10/23/2018 at 20:40 • 0 commentsAdded scaled reference image, rotation and scale is corrected, there is still some skew, particularly from top to bottom along the sides. The image resolution is adjusted to 640 pixels per inch in GIMP, this results in the 0.1" hole spacing equating to 64 pixels. Also added some transparent PNG's that were pulled and scaled from data sheets as basic references for assessing footprints.

Downloaded basic imagery and info from hackaday article and project page https://hackaday.io/project/161859-2018-hackaday-superconference-badge & https://hackaday.com/2018/10/17/the-supercon-badge-is-a-freakin-computer/
