I have also just uploaded a video of Sidney Alford's shape charge demonstrations: http://www.youtube.c...h?v=28u4uz9Itro

I also have some pictures of the fireworks just after setup. If anyone wants to see them, I'll post them for you.

Attached below is my video from last nights show. Unfortunately it missed off some of the higher shells, but it got the majority of the finale.

Thanks to everyone yesterday for making it such a great event!

My dad and I are willing to supervise the pyro whilst everyone goes and eats!
This has been a fantastic event the last 2 years I've been, so I can't wait for tomorrow!

I do not have much programming experience myself but my friend is awesome so I think I might be able to get some help from him!

The XBee units are constantly scanning for other devices and when they discover each other then whey will send each other a code. They will 'handshake' and create a link between themsleves. The handshake itself just consists of the exchange of codes to tell them that the other unit is there and how to communicate to it.

The handshake is standard for XBee units to do themselves.
Here is the XBee manual if you want to have a look.

Thanks Phil

I will certainly design in failsafe devices for the unexpected events! I certainly do not want any mishaps! In one of my earlier designs, if the receiver was turned on before the transmitter then it would automatically put all the outputs high! Not really what you want!

Thanks for the warning, I do occasionally need reminding that if things like this go wrong then it could all quite literally blow up in your face! Certainly an outcome that I want to prevent at all costs!

Thanks,
Fred
