gEDA-user: DJ's back
Is the site down? I can't seem to connect... Major storm hit NH, taking out power, phones, internet, roads, a few houses, and at least one truck. We're OK though, but at the peak there were close to 200,000 people without power in the area, mostly due to trees falling on power lines. We were without power for 51 hours, and without phone/internet for a little less than that. Fortunately, this happens regularly to us (it's a spring thing), so we had backup power, alternate heat sources, and even battery powered internet (VERY slow). However, our road was washed out just north of us and just south of us, so the only way to get anywhere was to take back roads around one of the washouts, then loop around town to get to the main road. The phone company's CO got flooded this time too, so phone service is still limited and spotty, and the cell system is overloaded. These were some back roads just up the street from me: http://cmonitor.mycapture.com/mycapture/enlarge.asp?userphoto=1image=59033thispage=1 http://cmonitor.mycapture.com/mycapture/enlarge.asp?userphoto=1image=59032thispage=1 More news and photos at www.cmonitor.com and www.unionleader.com. For those who don't know what a nor'easter is, here's a little weather lesson. The jet stream crosses the USA from West to East, and ends up here (East coast). As it turns up the coast, you get the typical cyclone system (think weak hurricane) with one side (the south east part) over the gulf stream in the Atlantic, and the other side (the north west part) over us. North of us is the cold air mass from Northern Canada. So, this weather system picks up warm humid air from the ocean, and dumps it on us as rain or snow. The prevailing winds are from the North East, hence nor'easter. Nor'easters can dump a LOT of rain or snow (we got 3 of rain) and create very high winds (up to 45 MPH here). ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: home-made dremel drill press
What I do is drill two pilot holes before applying the photoresist in the unusable border around the circuit and use them to align the masks before exposure. What I did this time is add some 13 mil vias outside the board (part of my usual process is to panelize two boards with a copper border around them to protect them against TT paper shrinkage), drill those vias, and use a few 13mil drill bits to pin the TT paper in the right place. The registration was off by about 10 mils, which wasn't bad, but I'd need to do better to use 13 mil vias (they're just the right size for wire wrapping wire). ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I cut the sides a little overside, then line them up using a strong light source. When they're aligned, I put a few staples in one end, verify I didn't tweak the alignment, and then staple the other end. Then I slide the board into the resulting sleeve. If you let it find its natural shape, the alignment is very good.

gEDA-user: Antenna Simulation
Hi, I'm searching for a graphical editor for antennas that produces input files for NEC (for those that don't know NEC: http://en.wikipedia.org/wiki/Numerical_Electromagnetics_Code). So it doesn't have to be a special antenna construction program, it just has to put out files in NEC format. I tried to run 4nec2 with wine under linux, but its so slow in the geometry editor that its not usable. Any ideas?

As for that chart, the interesting parts were the big gaps and its feeble attempts to keep up, not the actual temperatures themselves ;-) Fahrenheit is useful because the normal range of outside temperatures is 0 to 100 degrees. It's like metric, but with a more practical scale. Besides, we already use the metric system for drugs, soft drinks, and small pitch parts.

Re: gEDA-user: Antenna Simulation
Don't know of one for Linux. But in my experience, a graphical editor for NEC isn't of great value anyway. The amounts that the wire lengths are changing while you are tuning antennas is too small relative to the rest of the structure and to the screen size. What *is* useful is symbolic expressions in wire lists, so that specific points in space can be given names. Makes it much easier to move a wire joint, since by changing the X/Y/Z values for one point all the associated wire dimensions are adjusted. Brian Beezley's old AO and YO programs did that, and it was very convenient. I've often thought that a simple text-to-text preprocessor that resolved symbolic expressions would be very useful. -dave Stefan Dröge wrote: Hi, I'm searching for a graphical editor for antennas that produces input files for NEC (for those that don't know NEC: http://en.wikipedia.org/wiki/Numerical_Electromagnetics_Code).

gEDA-user: PCB testers needed
I got a whopping 1 response to this request a month ago but I figured I try again... This is good opportunity for active PCB users to help out! I have implemented user defined menus for the gtk HID for pcb. The menus are read from a resource file on startup just like in the lesstif HID. Instead of looking for pcb-menu.res, the gtk HID looks for gpcb-menu.res in the same locations. The reason for a different name is that the organization of the default menus for the lesstif HID is different than the gtk HID. However, the goal is for the menu resource files to be compatible. By this I mean you should be able to do something like ln -s pcb-menu.res gpcb-menu.res and have both the lesstif and gtk HID's have the same set of menus and hotkeys. One goal I had was to not change much in the way of the menu layout or hotkeys from what is currently in the CVS HEAD for the gtk hid. Despite this, I do expect there will be a few changes. One visible change is that all hotkeys are now defined through the menus. You'll see that under the Info menu, there is a Key bindings submenu. That is a catch-all place where all of the key bindings that aren't already assigned to the normal menus go. It has the side effect of providing an online reference. To try out the new menus, update to the usermenu branch. Do this by either cvs update -PdA -r usermenu from your pcb source tree, or check out a new working copy somewhere else with: cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/pcb login cvs -z3 -d:pserver:[EMAIL PROTECTED]:/cvsroot/pcb co -P -r usermenu pcb then ./configure --disable-doc gmake cd src ./pcbtest.sh The changes to get to this point were fairly far reaching and intrusive so I'd really really like feedback from some active users before I merge this work back to the trunk. What I'd specifically like feedback on are: 1) menus/hotkeys which worked in pcb-20070208 with the gtk HID and are broken now 2) any other wierd behaviour relating to menus or hotkeys that is different from pcb-20070208. 3) does this build with gtk = 2.8.0 and if so, does the Center() action (bound to 'C') work? Feel free to substitute current cvs head for 20070208. My goal is to get the usermenu branch up to the same level of functionality as what was in pcb-20070208 or current cvs head before merging the branch back to the head. While I care about bugs and other usability problems which existed in 20070208 and the cvs head, I don't want to try and address those until after issues which are specific to the usermenu branch are dealt with. Known issues: - Mouse section in the resource file is ignored. I need to learn about how the mouse buttons are handled in the gtk HID currently so I can hook up that section. - A fair amount of now obsolete code still exists in gui-top-window.c. I need to do some major house keeping. There is a file, src/todo which lists the remaining known issues with the usermenu branch. While I don't think this branch has any major instabilities in it, it should still be treated as alpha quality. So please make backups of any of your work! You have been warned! I'd love to merge this before the code sprint on saturday (or maybe as part?) but will hold off if problems are found.
