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.


Stay tuned for more updates....
