> Anyway, today I'm in. Do you like the brake circuit ? :-) http://russell.servepics.com/temp/r100b.gif Too many parts, but it works well. C41 delays the brake turn on slightly for reasons related to implementation. To get good switching in all cases theory and practice diverged a bit - my theory anyway. The FET gates need to be taken well above the V+ rail to get good switching. Even when R42 is changed to 1k (helps pull the floating motor low) it needs the high level gate drive. A single reed relay with a normally-closed contact and diodes D41 & D42 to drive it would do as well.
