Re: gEDA-user: PCB's at 10 GHz or 2.5THz?

Anyone doing anything in the THz range yet (yes, that is a 'T')? I have done 480THz. But it gets demodulated soon at the beginning of the signal path.

Re: gEDA-user: no pins in JUMPER10
I didn't put footprints in some components becouse I didn't get any error about that. They seem to have a default footprint already. Is it a problem to leave the default footprints? 2006/11/6, John Luciani [EMAIL PROTECTED]: On 11/5/06, Giorgenes Gelatti [EMAIL PROTECTED] wrote: i'm sending my project. it's very simple. Thank you. One big problem is that a number of your components do not footprints. For example --- max1, max2, trans1, uc1. The majority of your connections go to these devices. You need to pick the appropriate footprints for the devices that you are using.

I did already make my own, by copying the file for the DIP-40 part and changing it, mostly by editing the text in emacs and then by moving stuff around in gschem.

I'm not sure what your script does, but I would think that the real because reason is that pcb is fully capable of reading all old format data. It doesn't matter what new file formats look like so long as you aren't trying to use new features, write in one format and pcb will always be able to read it. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

If anyone wants FPGA code for 1-Wire, I have some. You can either click through the stupid (but innocuous) licence agreement at http://recycle.lbl.gov/llc-suite/, or e-mail me. I have two versions: one is a very simple one-bit transfer, minimal gates, but takes the real-time burden off the host computer. The other does enough sequencing to read a temperature from a DS1822; all the computer has to do is write the stimulus message to the FPGA at the beginning, wait 750 ms, and read the response message at the end.
