Nixie tubes, whereas largely a show methodology of the previous, are fabulous items of retro know-how able to exhibiting off characters as brilliantly glowing formed conductors. Immediately, you’ll principally see these tubes applied as fashionable clocks, however why not different family units?
As seen right here, and within the video beneath, SomeOnetyone created a three-digit Nixie tube angle gauge. The unit is pretty correct, even working upside-down at 1:55, and matching as much as a protractor at across the 2:10 mark.
This machine responds to angular displacement by counting up the digits proven on its three tubes. These are located on an higher perfboard stage, together with supporting electronics together with Siemens 74141 binary to decimal converter chips made in 1972. Extra elements include an Arduino Nano on the underside perfboard stage in addition to what seems to be a lift voltage converter to provide the tubes, plus an accelerometer.
The underside and prime ranges are affixed collectively utilizing a header association, which might facilitate straightforward troubleshooting and growth. The gauge’s firmware makes use of a shifting common to clean out the output which doubtless accounts for the ever-so-slight response time delay. Sooner or later, SomeOnetyone might combine velocity and acceleration over time features into the firmware, and a extra strong housing can also be deliberate. However, uncooked perfboard look does have a sure enchantment!
