Finding your way around this website
The content on this website has grown rather organically so I can imagine that sometimes it can be a tricky to find the information you are looking for.
So here a small guide to the tabs on the top of this page:

• Introduction
  The pages under this tab are meant to give a quick overview of the uTracer concept, the working principle, and its use. Most explanation will be done using the new uTracerNXT as example, although I will also use results and examples from the older uTracers 3 and 6. Under the sub-tab Project History you will not only find a small project history, but also a list of the uTracer versions I have worked on over the years, of which only a few made it into a real kit. An enthusiastic group of people has and still is contributing to extend the functionality of the uTracer family. You can find examples of this under sub-tabs Spice Modeling and Load line tool.
• Testimonials
  Already since the beginning of the uTracer adventure I have encouraged people to share their experiences and send me a few pictures of the tubes tester they created around the uTracer. Although the uTracer3 is no longer available, I encourage you to have a look at the hundreds of beautiful embodiments people have come up with!

• Order
  All the information you need to order a uTracer. Ordering a uTracer is a two-step procedure. You mail me first at Ronald@dos4ever.com so that we can first discuss technical related issues (if any). I then bring you into contact with my wife who is handling all practical stuff like finances, administration and shipment.
• All Weblogs
  I like to use the weblog format to document the development process of the uTracer projects. The weblogs force me to properly write down the thought process driving the development. They are therefore primarily intended for my own documentation, but I know many people find them interesting to read. On the Project History page you can find a table listing all the different uTracer versions including a link to the corresponding weblogs.
  Shortcuts to the main weblogs pages for the: uTracer3, uTracer6, and uTracerNXT
  Of special interest is the Lab Notebook page which discusses ideas and concepts that one way or the other do not fit in the regular weblog pages. Many of them relate specifically to the now obsolete uTracer3, but some of them are also of interest to users of the utracer6 and uTracerNXT such as:
  • Tracing transistors
  • Measuring the anode resistance of pentodes
  • Forming electrolytic capacitors with your uTracer
  • How to accurately trace diodes and rectifiers with the uTracers
• Frequently Asked Questions (FAQ)
  A list with some of the questions I regularly get, including my answers. Currently the questions are still very much focussed on the uTracer3. Re-organizing and updating of this page is also very much on my to-do list, but nevertheless, the page contains very useful information.
