Well, I have plenty of T's, and yes, for RC projects I think I would need to move to XT-60s some day. But as my current project is pretty much one-time one, I thought about using some of the T's from the large bag I already have :-) : The xt60 line of products includes regular side mounted versions. Interesting, I didn't know that. Actually, even T's are a bit overkill for my project, I expect the continuous current to be around 3 Amps only. So I might also look for XT-30s. : > If not - can somebody guide me how to create it?

This route is described in this very detailed manual: : http://wiki.geda-project.org/_media/geda:land_patterns_20070818.pdf : : 2) write a script in your favourite language to generate the footprint : file. This footprint generator approach is particularly useful if you : want to produce a large range of similar footprints. : : 2a) use a footprint generator written by somebody else. : : 3) use the GUI of pcb itself. You'd compose the footprint from lines and : pads. Then copy these elements to buffer and apply : Buffer → convert_buffer_to_element : Insert the footprint on canvas with a left-mouse click. : Add pin numbers and move the footprint string to a proper place. Check : and potentially change clearance of solder mask. : Copy the footprint to buffer and do : Buffer → Save_buffer_elements_to_file : This GUI approach is more tuned to deal with "interesting" shapes that : connectors tend to ask for. : For my own work-flow I added a few scripts to streamline the GUI : approach. (set the clearance, set the line width, extract all footprints : from a sheet) : : Hope, that gets you going, Thanks, I'll have a look at it. 1) seem to be the preferred option for me. -Yenya -- | Jan "Yenya" Kasprzak | | http://www.fi.muni.cz/~kas/ GPG: 4096R/A45477D5 | IORING_OP_NOP ... the benefits of doing nothing asynchronously are minimal, but sometimes a placeholder is useful. --Jonathan Corbet at LWN
