A short while back on the microwave reflector, I posted a reply to a
question on a -20v DC/DC Converter. Since there are a lot of rovers on
this reflector, I thought I might also post this on the VHF reflector.
While I did not make a negative supply, I did make a positive boost supply
using the LT1070 to provide battery power to my laptop. Laptops normally
require 18v to 20v and internally convert it down. Unfortunately, the will
not operate directly on auto voltage. I mentioned to a couple of folks, I
would do a short write up for them. If anyone is interested, you can see
the results including photos on my website. Here is the link:

As time permits, I will put some more of the projects up on the site.
