“A spectrum analyzer is a measurement tool that displays real-time frequency analysis of incoming audio signals. It is usually an integral part of equalizers and audio signal processing devices. The vertical axis shows the amplitude of certain frequencies measured in …
“How to make a VU meter with 38 bars per channel on a modified 20x2 VFD display. A vacuum fluorescent display (VFD) is a display device commonly used on consumer electronics equipment. VFD emits a very bright light with high …
“Weather forecaster, which displays the weather forecast on the screen in the form of descriptive text. Story In one of my previous videos, I described how to make a cheap Advanced Barometer, used by sailors, yachtsmen, etc. It is a …
“This is a nice retro-look weather station and clock that I made with a POS VFD display for which I did not have any data and information. The device is very simple to build and contains only a few components …
“This project builds upon the PIC/TI83+ interface developed by ThomasHenry (see Nuts & Volts August 2013 A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project …
“Using an old VFD serial communication display for use with Arduino based microcontrollers. Story I remember back in 2018 that I got this screen (from an old guitar pedalboard) and didn’t know how to make it work. I was …
“This project took almost half a year to complete. I cannot describe how much work went into this project. Doing this project alone would take me forever so I had some help from my friends. Here you can see our …
“A DC Load is useful for testing lots of different things. If you have a power supply and want to make sure it’s able to deliver its fully designed potential, then you can use a DC Load to test …
“This is a vintage VFD tube clock that uses Ethernet for both power and data. The power is provided using 802.3at PoE+ and a Molex PD Jack that contains both integrated magnetics and a PoE Type 2 PD controller …
“The displays are driven with a daisy chained shift register. The converter on the left generates the 24V rail and the centre converter provides 1.5V for the filaments. Both converters can be disconnected via jumper for initial setup and …
