Here is a collection of web pages of VU Meter projects that helps a newbie getting into the Electronics DIY Hobby Land.
A Hobby now in your School days or College can help you build a strong profession later. It is Edutainment that will make productive use of your spare time. Friends can do it as a group, during holidays. Parents should encourage healthy hobbies, as the children will grow in a positive and creative atmosphere.
Stereo led level meter – This is it. It’s a STEREO LED LEVEL METER. It’s the cheapest and best bar graph display available and best of all, it uses readily available components.
VU-meter by Archy – Then it hit me. A VU meter, big, beautiful, professional! From that moment started my thoughts flowing. Those VU-meter ICs that are sold in every electronics shop?
LM3914 dot-bar display driver – The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, providing a linear analog display.
Knight Rider Display Project – This project started out as a VU meter. I reused parts and pieces to improve the VU meter and give it additional functionality. It is amazing how much time it takes to create a small thing like this.
Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer’s sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal – which can be music, speech, or output from an electronic circuit.
Zelscope Sound card oscilloscope
Zelscope features the interface of a traditional oscilloscope, with conventional gain, offset, timebase, and trigger controls. As a real-time spectrum analyzer, Zelscope can display the amplitude and phase components of the spectrum.
The typical input voltage should be about 1 volt AC at the line-in jack of the sound card, so a voltage divider or a buffer amplifier is highly recommended.
xoscope for Linux – Similar Ptoject
Zelscope also allows for an easy measurement of short time intervals in mechanics experiments. Zelscope has proven useful in debugging music and sound processing software.
Hobby Electronics, Computing, Kits and Projects. Online version of Australia’s only electronics magazine, and is primarily directed to professionals, trades people and enthusiasts in the electronics, electrical, computer and related fields.
Silicon Chip Electronics Magazine
Projects to build do it yourself to save money, to learn new skills or simply for the fun of it!. Serviceman’s Notebook Actual cases, often unusual, from the bench of a full-time serviceman. Vintage Radio bringing back to life the discards of previous generations.
Each Silicon Chip design is carefully checked and tested and readers with the appropriate construction skills should be able to duplicate the design and have it work in the same or similar manner to the prototype.
