Ultrasonic Anti-Fouling Unit For Boats, Pt.2
22 November 2010
In the September issue we published
the details of the ultrasonic driver for
this project, which is housed in an IP65 case
for safety and protection from water ingress.
This month we describe how to encapsulate the
ultrasonic transducer so that it is completely
safe to handle. Once it is encapsulated it will operate reliably, even if it is submerged in the bilge of the boat. We also show a typical installation of the system in a large power boat.

Ab RFID Security System
14 November 2010
Here's a high-security system that's very easy to build but offers you peace-of-mind for your home, car - in fact, anything where entry needs allow the good guys in but reject the bad guys. Team it with an electric lock and you can have a keyless entry system as well!

Digital Lighting Controller For Christmas Light Shows, Pt.2
08 November 2010
Everyone who has seen this has been pretty impressed . . . and no wonder! While we originally intended it to make your Christmas Lights display the best in your suburb, with up to 32 channels and total power limited only by your power outlets, it's capable of controlling just about any lighting sequencing task you want to throw at it. Now we get on with the good stuff: putting it all together!

Build A GPS Boat Computer
24 October 2010
For all the boaties out there, this one could literally be a life saver!
You'll never be lost again: as well as telling you exactly where you are at the moment, it will also show you your speed and heading and can even navigate you back to your starting point or to that secret fishing spot! It can even tell you how much fuel you're using, along with a host of other vital information.
