Kerry Wong shows off his VFD clock he built after he completed the filament driver and the circuit to drive the multiplexed VFD segments we cover previously: After I completed the filament driver and the circuit to drive the multiplexed VFD segments, it is time to finish the VFD clock project I had in mind […]

A DIY vacuum fluorescent display driver
Kerry Wong posted an update on his vacuum fluorescent display driver we covered earlier: As I mentioned before, there are many driver chips (e.g. MAX6921, MAX6931) readily available for interfacing with VFDs. The driver circuit I am showing here is a bit more complex as it uses only the generic 74HC’s and discrete transistors. The basic […]
VFD filament driver using 555
Kerry Wong documented his VFD filament driver built: I recently salvaged a vacuum fluorescent display (VFD) from a piece of old test gear. The VFD is a 13 digit 7-segment multiplexed display and I thought it would look great in a custom digital clock or something similar. While it has the model number FUTABA 13-MT-54NA, […]
