Re: gEDA-user: PCB Lockup/Optimization
Thanks for the help, that is indeed the problem. It appears whenever I autoroute the board AND it puts a via next to the edge of the board it's creating all those unnecessary traces. If I can keep it from putting traces on the edge of the board then I should be fine. Thanks again for you help.

There's a via at 47.43mm, 18.54mm. It appears to serve no purpose, as it has only lines from layer two connecting to it. However, *under* the via is a tiny copper trace on layer 1 (make vias invisible and you'll see it, but it does stick out a little on the side). At least, so it seems. It turns out you have *1500* tiny copper traces under that via. So, shut off layer 2, use a rectangular selection box to grab all those traces and the via, and delete them.

gEDA-user: PCB Lockup/Optimization
I have a PCB design that I have hand routed the power nets and then let PCB autoroute the rest. When I go to do to an optimize(say miter the traces) PCB just locks up and never returns, I have to manually kill it. And I have let it run for hours and it's still locked up. Is this a known problem and perhaps fixed in a later release? I have a fairly old version(2+ years). I have never seen this problem before, perhaps it's just some odd issue with this specific layout. It also seems to lockup if I tell it to rip up the auto routed traces, which leads me to believe it's a problem with the auto routed traces. _ Get back to school stuff for them and cashback for you.

Re: gEDA-user: Using SMT
Some tips on thermoelectric cooling: 1) Make sure you purchase sealed thermoelectric modules(the elements are sealed completely typically using silicone). If the units are not sealed condensation will form on the thermoelectric elements and they will literally fail within an hour or two. 2) Pressed fin type heatsinks work well in removing the heat. Blow the fan inward against the fins, do not blow laterally across the fins. Your best heat removal comes with turbulent air flow, not laminar air flow(which is why blowing inward, perpendicular to the fins is best). 3) Any ripple on your DC current will add unnecessary heat to the assembly(ie: heat that works against your cooling capability). Setups like you see for cooling microprocessors are a good analog and you should set up something like that to cool your modules. 4) As the temperature diffence between the cold and hot side of the thermoelectric increases the cooling capability goes down. Hence the better your heat removal capability(heatsink/fan) the better off you are. 5) When you assemble the thermoelectrics, sandwiching them between the heatsink and the cold plate make sure you use a torque driver to get the same torque across each screw. Use something like a bellville washer on each screw to equalize the pressure: http://www.rctek.com/fixings/bellville_washers.html If you have uneven pressure across each of the screws you could end up damaging the thermoelectric modules as they are fairly fragile. Also use an insulating washer on the screw on the cold plate side to isolate heat transfer along the screw from the heatsink to the cold plate. Good luck with your project.

That 500MB does not include VMWare. You simply link to the VMWare player download. My feeling this is irrelevant in the discussion. My uncompressed VMWare image for Fedora5 is ~3GB. I am guessing compressed you are looking at a 500MB download. I suspect you could do a stripped down version of the distro without things like OO that might help in that dept. If you want to pull in a broader audience this is a great way to go. You don't have to do anything to your Windows system other than to install VMWare Player and download the image.

Re: gEDA-user: VMPlayer Image
VMWare Player is free. There are also freeware tools out there to create VMWare images. From there you can do your linux + gEDA install and you are ready to go. The hook I've encountered in the past is I was never able to get the CD installs for gEDA to work on Fedora on a VMWare image. That may have changed recently. I've also tried qemu. It works but is an order of magnitude slower than VMWare. Interestingly certain linux variants were much slower than others on qemu. I did run Fedora Core under qemu for awhile and it was servicable. But once VMWare player was free there was no going back, the performance difference was substantial.

Re: gEDA-user: www.66each.com
I've used pcbfabexpress many times, both for double sided and 4 layer boards. Not a single problem so far. I used Advanced Circuits only once because their intro offer was good(check out their first $500 free offer). Otherwise Advanced Circuits is way more expensive than just about everyone else I've looked at. Company name can exist for ~$150 in just about any state in the US.

Most mosfets are driven with typically 10-12V for the gate drive. I have never seen a mosfet with a 50V gate drive requirement. If high side drive is a concern here you may want to look at bootstrap devices that are available to drive the high side mosfet. It's unclear to me exactly what you are attempting here but if I read it right you basically have 10V to work with(+5 and -5 supplies).

Does PCB have a renumbering command? This would be a command that would renumber the components on the circuit board say starting with the smallest value in the upper left and then proceeding to the lower right corner of the board. And this would also generate a was/is list, showing the old component refdes and the new one(ideally you would have an app that could take the was/is and update the sch file). ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Well at least with this proposed mod(the renumber) one would definitely want to update the netlist.

RE: gEDA-user: OT: UV exposure?
Most glass products block deep UV rays, you actually have to spend quite a bit of money if you want to use glass that will pass 350nm and below. And most clear acrylics will block UV(again,you can get UV passing plastics but they cost $$$). Glass has the advantage over plastic in that UV exposure will smash the bonds in the plastic and cause it to craze, this is what you see on older plastic car parts where it looks like the color has bled out of them or in clear acrylics the plastic almost appears to have shattered w/o breaking apart. So if you want a window that holds up over time I suggest going with glass(and no boro float glass, that passes UV). I might suggest only putting a window on the areas that require illumination. Cover everything else up. UV is nasty and it's energy is great for smashing the bonds of just about any material, plastics or DNA(skin cancer anyone?).
