DIY easy to build audio signal-tracer project for 2019.
Hey everyone,
I've got a new DIY project scheduled for 2019, it is a piece of test equipment called an audio signal-tracer, the design outline is as follows:
* Has to be relatively easy to build so that newbies to electronics can build it, but at the same time, a bit more complex than a simple audio probe.
* Includes a stepped attenuator so that the audio signal-tracer can be used to trace signals in circuits where large signal levels are present, such as solid-state or valve guitar amplifiers, as well as DIY guitar effects pedals.
* Includes a variable volume control.
* Includes an internally mounted speaker.
* At least 1W audio power output.
* Includes an audio signal generator.
* Battery, or mains powered via a plugpack adaptor.
* Includes a probe with a grounding wire.
I'll be including a write-up of how I go about building the audio signal-tracer, which will also include a complete parts list so that anyone interested can build one for themselves.
