I can attest that I gained experience across a broad range of disiplines during the design, construction and debugging of this train set and I trust that there will continue to be curious students and hobbyists who might also find them interesting and informative. I hope that some of you will be inspired to use your computers for something non traditional, as I once was. As my train set had its genesis as my own student project, I admit that I like to make time to answer quesions and offer help to the next generation of engineers and hobbyists. Drop me an email and let me know if I can help you start your own computer controlled model train.

We offer an eclectic range of products, many with a science or educational tilt to them, others simply handy or amusing. Value is important, and whenever we can, we carry surplus at prices well below retail. We love closeouts, inventory overruns, mis-manufactures, and items whose time has not come.

This site is intended to reflect my interests in electronics, computing and model railways. There are details of my present system and how it works, in addition to several practical projects.  Over time, I hope to add new projects and information, relating to the electronic control of model railways, and how to interface and control them using microprocessors or the PC.

Soldering is the process of a making a sound electrical and mechanical joint between certain metals by joining them with a soft solder. This is a low temperature melting point alloy of lead and tin. The joint is heated to the correct temperature by soldering iron. For most electronic work miniature mains powered soldering irons are used. These consist of a handle onto which is mounted the heating element. On the end of the heating element is what is known as the "bit", so called because it is the bit that heats the joint up. Solder melts at around 190 degrees Centigrade, and the bit reaches a temperature of over 250 degrees Centigrade. This temperature is plenty hot enough to inflict a nasty burn, consequently care should be taken.

Welcome to my personal page of electronic circuits that are mostly for model railroads. Shown are designs that were developed to solve certain problems or achieve a desired control function. There are throttle, train detection, animation, control and general purpose circuits on this page.

One thing I have tried to do is not show a schematic drawing. I feel that this scares many people away from electronic projects. For those who know how to read a schematic, please do not feel insulted.

Rutger Friberg is Model Railroad and Electronics editor in the leading Scandinavian MR Magazine \"Allt om Hobby\" since more than 20 years. Rutger is also author of a series of books in the area of MR Technology as well as co-author of Hobby and Technology books in Scandinavia. For many years (since1988) Rutger has also on a regular basis been giving seminars and workshops for broader audiences around the MR and technology topics. Since1991 Rutger has been member of the DCC working group within the NMRA technical committee and instrumental in bringing the Digital control system to the level of a National Standard in the US. In this context Rutger has also been giving a great number of clinics at each National Convention since 1992. Rutger is working hard to get new kids into model railroading, he developed the Junior Collage Programme and introduced it at the NMRA Convention in Kansas City in 1998. This programme has since then been very popular and been held in many places in Asia and Europe as well as yearly at the NMRA conventions.
