Opinions: Last call for WPC Driver Board Feature Inputs



Going into final layout this weekend (unless the weather is nice) of our WPC
Driver Board. So far we have:

-Improved the 5V supply to work down to 5.5V input (from 7.5 in original
design)
-Removed all Bridge Rectifiers and replaced with Diodes (as per WPC95
design)
-Reduced inrush current into the existing 15000uF Capacitors
-Added a LED for the 50/70V supply
-Simplified (extremely) the Coil Drives

Any other improvements you would like to see in a low cost replacement
board?

PS low cost means that the feature should add a lot of cost.

PSS Does anyone really use the dimming feature? I could cut about $15 off
the board if this feature was removed.
