Look what I scored on eBay. (LEGO guy for scale.)



Six IN-14 nixie tubes. These are such great tubes. They're a really good size, and they're pretty common on eBay. That makes them cheap. It was only $18 for six.

I've been wanting to do another nixie clock for a while. It's been a year and a half since I completed my first nixie clock. I think it's time for another one.

I can't believe it took 51 days for them to arrive. I ordered the tubes and received an email from the seller stating that he would need an extra week to mail them. He threw in an extra IN-19 for the trouble. It then took about a month and a half for them to arrive from Russia to the US. I guess they got hung up in customs, or were misdirected at some point. In any case, I wasn't in any rush to get them since I was putting the wraps on other projects. I'm just glad that they finally arrived.

Let's try them out! I set up my trusty nixie power supply and was able to power them no problem. I like these tubes way better than the IN-12s that I used in my last clock.



The IN-19 is pretty cool, but I have no idea what I'll use it for. The IN-19 comes in three varieties. This one displays the following characters: Pi, A/B, ~, <, -, >, +, dB. I'm not one to look a gift horse in the mouth, but the other variations contain °C and F. I could have made better use of one of those. They might have come in handy in a thermometer. Oh well.



I don't know if I should start from scratch, or use some of the remaining boards from the first nixie clock. The first clock was made up of 3 PCBs stacked on top of each other. (The main board, the driver board, and the display board.) I might keep the main board as-is, and combine the display and driver boards into one. It looks tricky, but I might be able to pull it off. It's just going to be hard running the high voltage traces.
