Interfacing a Noritake VFD Module with Arduino

I recently bought a Noritake-itron VFD module off eBay. Noritake-itron specializes in making vacuum fluorescent displays for many OEMs. As such, there are many surplus modules being sold in secondary markets. The module I got has the model number CU20026SCPB-T26A, but unfortunately there’s not much information available on the internet for this specific model.

Inside an Agilent 66312A Two-Quadrant Power Supply

Typically, a lab power supply can only operate within a single quadrant. Take a positive voltage power supply for example, it can only output or source current. If any attempt is made trying to sink current into the power supply by connecting a voltage source with a higher voltage than the output voltage of the power supply, the power supply would lose regulation since it cannot sink any current and thus is unable to bring down and regulate the voltage at its output terminals.

VFD Clock – Putting Everything Together

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 earlier. Continue reading ‘VFD Clock – Putting Everything Together’ »

A DIY Vacuum Fluorescent Display Driver

In my previous post, I showed a simple vacuum fluorescent display filament driver built using a 555 timer and a custom hand-wound, center-tapped toroidal pulse transformer. And as promised in my earlier comment, I am going to show you the remainder of the VFD driving circuit here. Continue reading ‘A DIY Vacuum Fluorescent Display Driver’ »

VFD Filament Driver Using 555

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, I could not find any information on the internet specifically for this model. Continue reading ‘VFD Filament Driver Using 555’ »
