Last October we learnt about "Total Internal Reflection".
shown here in this photograph. The LASER beam does not hit Tony's palm becase it is reflected inside the stream of water and bent downwards.
A while ago Alan presented an interesting demonstration on filters.
For example, how to stop your repeater input from overloading due to your repeater output being so close to the receive frequency, and so very strong compared to the signals that you are trying to receive.
Toby gave us a great demonstration on all sorts of Arduino kits and inspired us to go out and make something interesting.
Here is just a small sample of some of the boards that he has either bought, or made from kits, or designed and made himself.
Toby said for more information, have a look at the blog on his website at www.vk2tob.com.
This is followed by the Trans Tasman 160 Metres Contest held on the 20th of July 2013, showing the sparks coming from the chimney and part of the Double Bazooka Antenna.
This proves that you don't have to freeze to have a great signal.
Also a view from inside just getting ready before the contest began.
