Vfd Clock Schematic. The iv 6 indicators are used. Now if your tube circuit sort of set up get your microcontroller ready.
6 digit iv 11 vfd tube clock. The proposed 3 phase vfd circuit can be universally applied for most 3 phase ac motors where the regulation efficiency is not too critical. Vfd tube clock i would like to present to the public the project of my watches on vli.
In the end the oscillator frequency is about the same at approx 30khz calculated with formula f 1 0 693 c4 r3 2r2 in the schematic below.
The proposed 3 phase vfd circuit can be universally applied for most 3 phase ac motors where the regulation efficiency is not too critical. Introducing openvfd the colorful vfd tube clock with light effects that make the clock dance glow or turn into a rainbow i m here to share my result of creating my own dream clock with you. Clock pin of the 74hc595 pin 11 sck to pin d2 of the arduino uno. Vfd clock ys13 3 discontinued led clock graphic 5 7 1 6 discontinued nixie clock qs30 1 discontinued quick links.
