I have reserved for two type of temp&humid sensor IC on PCB ,one is SHT2X and Ti's HDC1000
originally I wanna to use HDC1000, but I find out that I place the IC too close to the mount hole,
so I turn to HTU21D
The sensor's placement is already near the drill hole for battery switch, but still influence by something on PCB, so maybe I'll just drill another one at the back, and put the sensor inside then pull out the I2C bus to main board to eliminate possible heating component.

Very nice build! I am a huge fan of wooden enclosures.
On a side note, where do you source your nixie tubes from? I would be interested in playing with them, but never know a good place to get them from.
Cheers
Hi,
I bought on Ebay , lot of Nixie tube there.
mostly IN-Series , like IN-14 or IN-18 (biggest) ,
this project is using IN-17 ,which is the smallest in the Series
(Because I can't afford the biggest one for six tube haha)
