Tech OnLine is a veritable haven for electronics engineers and information technology professionals. After completing the free registration process, users have access to live and archived Web casts, online courses, and technical papers. An example of the roughly hour-long Web casts is a touchscreen liquid crystal display design, but this is just one area of many. The site is continually updated with feature articles that cover many different hot topics, including a recent look at fourth generation wireless communications. A discussion forum is also available, but it does not seem to be very active.
