Recently I have acquired some IV-6 Soviet Numitron Tubes. Numitron tubes are just similar to normal vacuum tubes, but they run on low voltage and current hence making them highly attractive for low power project use.
Remember that $4 multimeter that I took apart? Well, I still have it. And its not very reliable nor useful. So, I have decided to make it useful! How you may ask? Well, I am going to make it display temperature so I can estimate the temperatures of different components and heatsinks. This is based on a tutorial by Embedded Lab, so I take no credit for the idea of this build. Here is the link to the project: http://embedded-lab.com/blog/?p=4951. I was thinking about doing a tutorial, but it’s already on Embedded Lab and I don’t want to plagiarise so I am just going to go through how I built this and a few modifications that I have made to the original circuit.
