I'm a high school student from Athens, Greece. I like to play arround with electronics, computers and programming. I have created some websites for school clubs and for personal use and i have participated 3 times on the Greek informatics competition. I also have done a bit of 3D design and 3D printing.

Unfortunately I do not, I made this instructable a long time ago. The provided schematics provide almost a complete diagram. With basic knowledge of electronics and a bit of tinkering arround following them carefully will do the trick. Let me know specifically where you need help!

I'm very sorry for the delayed reply, I have been inactive for a while. I wrote that code a long time ago so I had to take a look and that's what I came up. My code uses the function shutter to return the digits of the number that you want to print. What it does is it multiplies the number by ten (ex. 14.5 -> 145) and returns the 1st, 2nd, 3rd digit depending on the attribute y. When you feed it a 3 digit number like 145 it will turn it into 1450 and will return 4, 5 and 0 instead of 1, 4, 5. What i think will solve your problem is deleting or commenting out the line in the function that multiplies x by 10 (I actually quickly tested this in Python and it works so you should be ok). Then to remove the dot from the display just don't connect the pin of the 7 segment to power!

• I get the principle for controlling more nixies but how do you power them? Can i just connect all annodes for my 6 nixies (for a clock) on the same 180V anode of the power supply? And where does the cathode of the power supply connect (From what i understand all grounds/cathodes go together)?

I know it's been 4 months but i had the same problem. I guess you have FSX Steam Edition. Go to FSX installation folder (/steam/steamapps/common/FSX) and find the SimConnect.msi on /SDK/Core Utilities Kit/SimConnect SDK/LegacyInterfaces/FSX-XPACK. Run it, restart and you should be all good!

Basically remove the part of the code that calculates the speed. Just place the sensor far away from the center. A problem I had was the sensor not being able to catch the magnet due to the high speed.
