Email, and other dangers

We recently had a spate of emails arrive at work, some claiming to be from RBS and some from Santander.

My curiosity got the better of me, so I saved the attached Word document, brought it home, and studied it on a Linux machine.

It turned out to be rather easy to pull apart, but rather difficult to piece together and understand.

The FG-100 DDS Function Generator

I needed a stable sine wave oscillator that I could use for a couple of projects.

After a quick search on the net I found I could buy a multi-function generator via Amazon for only £27 post free.

A couple of weeks later the FG-100 arrived, with absolutely no documentation. Fortunately it is very easy to drive.

Bat Detector Overhaul: Portable Field Unit

Sooner or later I'm going to have to accept that the bats are not coming to me, so I need to get out and find them!

I could do that now just using the hand-held bat detector. But I'm thinking it would be nice to test the whole automatic design illustrated in an earlier post.

So I've put together a rough outline schematic and started collecting bits & pieces.
