Re: gEDA-user: OT: help needed; asymmetric load after rectifier seems to disrupt its working.

Vcc and Vss are still sensitive to load. So if the design requires both Vss and Vee be equal and opposite, then it needs regulation - zener, for example. Your absolutely right, but that's what comes next. It is the regulators how create the difference in load balance.

gEDA-user: Draft documentation for Scheme API

2011-06-24 Thread Peter TB Brett
Hi folks, I've now written the documentation for the Scheme API so far (in TexInfo, simply because that was the quickest way to get it done and looking nice). I've put an HTML version on the web temporarily here: http://peter-b.co.uk/geda/geda-scheme/ That URL will change soon(ish), and I'll

gEDA-user: gschem add net problem

When I create a schematic, if I try to put more than one symbol on a net, it does not take. For example, if I were to put three resistors vertically, right next to each other, then add a net across all three on top, and another across all three on bottom, gschem indicates by adding a dot,

Thank you for your response. So how would I include the center resistor in the net as described in the example below, other than moving the resistors around in a irregular pattern and creating separate nets? I've tried creating separate net segments, but as soon as I add the next segment,

OK, I think I finally see it. In the example below, I would need to place a net from the pin of the middle resistor to the net connecting the outer two resistors. I can't just drop the pin of a part on an existing net. Tim On 06/24/2011 06:48 PM, Phil Taylor wrote: On 6/24/2011 4:06 PM,

I usually draw net stubs coming off any long net for the visual safety of seeing each one fully drawn. The risks of not doing it this way seem to great. It also makes different sized symbols fit in parallel without issue. So for three parallel symbols sharing one net there would be at least
