Anyone interested in building their very own Nixie tube indoor thermometer may be interested in a new kit created by Juergen Grau aptly named the NixieTherm. Featuring an IN-13 Nixie bargraph tube indoor thermometer kit offers a fully analogue design powered by a 5v USB connection. Watch the demonstration video below to learn more about this very unique thermometer that is sure to be a conversation piece.
“A Russian Bargraph-Nixie-tube shows similar like in the good old time a mercury thermometer the room-temperature with a variable glow hight lenght; however with NixieTherm you have a wonderful red-orange glow. At the same time six RGB auto colour changing LEDs, which illuminate the scale from the botton, give a never ending play of millions of different mixed colours.”
Features of the NixieTherm DIY Nixie tube thermometer kit include :
– Only analoge technique is used – The electronic circuity runs without any processor or other digital ciruity.
– Power supply via USB – Power consumption is as less as NixieTherm can powered up from a simple USB port. No driver needs to be installed. NixieTherm only “catches” the supplied voltage. As an alternative, NixieTherm can be powered from a standard Mini-USB charger.
– Low power consumption and self heating – 50…250 mA @ 5VDC depending on the lenght of the glow coloumn thanks to the high efficiency voltage tripler in the HV supply.
– High accuracy with LM35DZ temperature sensor +/- 0.5°C (+/- 1°F) adjustable.
– Displayed temperature range 14…33°C / 57…92°F
– Fully smoothed display in contrast to the steps on a digital controlled tube.
– The electronic kit – You get a complete electronic and mechanic DIY kit – and complete means complete:
– All electronic parts + PCB with assembled and soldered SMD parts
– Tested IN-13 Nixie bargraph tube
– All mechanical hardware and enclosure parts
– SMD pre-assembed
