PocketPC: Direct download
Electro is the premiere electronics and electrical reference utility
available for the PocketPC. With an assortment of calculators, reference
tables and other invaluable tools and information, Electro is one program
you can't be without if you work with electricity in any form!
Electro received 5 stars (the highest rating available) from Roger Kadau of
Romulus, Michigan (Detroit Metropolitan Airport) who had this to say about
Electro:
"Fantastic product for the electronic hobbiest!
I'm the owner of an Ipaq PocketPC and I love this product. It's fast and
it's full of information.
Electro was rated 5 cows (the highest rating given) by
Tucows, one of the most respected
software review and download sites on the web!

555 timer design
Shows you the two basic 555 timer circuit configurations, astable and
monostable. For each you can enter component values and see the
resulting time and frequency output. Good for quick designs!
