Valve Radio

The valve radio in the picture receives from about 1Mhz through to about 10MHz i.e. medium wave to short wave. Picked up Beijing Taiwan etc after 6pm when they start transmitting. Uses a speaker not headphones. Circuit is my own design. This is my valve electronics prototyping board. Why valves? Because I am just a bit young to have really had to use them so this was more of a fun exercise!

Model Railway

Although pleasently simple at face value there is a lot of skill in creating authentic scenery, writing the software to control modern digital trains DCC. Shunting so as to re-arrange wagons into the correct order gives a certain mathematical element to the whole thing, something you don't appreciate on the usual roundy roundy layout.
