Every now and again, I make something other than clocks.. this is Dynamic Thermo and as you can see it is a Thermometer. This one in Fahrenheit as it now lives in the USA.
Made from an old DC Potentiometer thingy, it now has a 3 digit temperature display and a special Symbol Nixie tube to indicate the 'F' range on the RHS of the readout. Dating back to the early 1970's the piece of equipment is made from Melamine and Aluminum, and is a type of measuring bridge used to identify unknown resistances in lengths of cable.
I do have some more of these in the starting points, so if you wanted a little thermometer to compliment your collection of Nixie clocks, then just get in touch!
