Hi Matt, will kokopelli have some sort of retro/compatibility mode so that we wan continue designing .cad circuit boards with it?

Thanks

Hi PartyTonight,

Short answer: No, but I'm developing a new library for pcb design and plan to port
Neil's example files.

Long answer:
All of Neil's PCB example files rely on an older render path that has been deprecated
for about six months. I'm not interested in maintaining both render paths (and the newer
render path is faster / better), so the GitHub version of kokopelli will not support .cad
circuit boards as provided in Neil's examples.

That being said, I know that a lot of people like starting from the examples and iterating
to create their own circuits. I'm working on a new pcb library (you can see the scaffolding
beginning to emerge in koko/lib/pcb.py) and plan to port over the example files once I'm
done. I plan to finish this task by the fall, so students in fab class will be able to use a
set of examples that actually work with kokopelli.

Let me know if you're interested in helping and testing out the new koko.lib.pcb library.

I'll be keeping this issue open to provide progress updates.

EDITED.

Hi Matt, thanks for your response.

Absolutelly, I'l be glad of helping beta testing and porting Neil's .cad files to the new library.

Also one of the things I wanted to add to the old PCB library was a set of dot matrix characters in order to place text in the boards like this:

final-06dotmatrix

The idea is to make a class (?) for the dots that make a circle depending on an array of parameters that are 1 and 0. And then create a library of characters that actually are arrays of 1's and 0's.

The advantadge over a font is that with dot matrix everybody can create custom characters (japanese hiragana, russian, arrows, etc…) just by changing the 1's and 0's. Also the dots could be as small as the milling bit.

I am now researching what would be the best matrix size (nxm dots) in order to be as universal as possible.So far I found that 5x7 was a standard back in the old dot matrix printers allowing numerals, uppercase and katakana. So that would be my starting point.

Cheers

Francisco

So class L_1210 from the old library would look like:

_pad_1210 = s2d.rectangle(-.032,.032,-.048,.048)
class L_1210(component):
''' 1210 Inductor
'''
pins = [Pin(-0.06, 0, _pad_1210), Pin(0.06, 0, _pad_1210)]
prefix = 'L'

So are you going to translate all the items from the old library (listed below)? How can I help?
