OK thanks, here's the close-up you wanted (doesn't show on the other side of the circuit board):

Think I got the jist of it :D

Diode, capacitor and relay added to basket, proceeding to check out :)


Thanks.

Edit: Dammit, they didn't have any sockets suitable for the low voltage relays, now my soldering skills will be put to the test :shock:

MrCrowley,

You might want to take a look at the following link, in particular the first circuit shown on the page.

http://www.the12volt.com/relays/page5.asp

For things similar to this I prefer to use the following kit:

Hope this helps.

Can I add antennas like the ones below to the transmitter to boost the range?
1
2
3

They would look pretty damn cool as well :D


In other news, some lady from the company I ordered from (element14) rang me up and asked what I do, to which I replied student, and then what I study and where I study. They probably ring up first time customers to see if they're working on any prototypes, I understand big companies like element14 who deal with extremely cheap components look for prototypes and offer out their products for free in the hope the prototype will get mass produced.

Or they think you're going to use it to build a remotelly controlled IED :shock:

On a similar note...

My parents had known about "Miniboy" since it first arrived back in June, a family friend came around the other day and my mum told her a little about it, the family friend thinks I'm going to shoot someone with it. The other night my parents go to a 50th and my dad comes back and tells me he doesn't want me firing Miniboy on the beach because it's too dangerous. Apparently, a different family friend had told him that he had heard I was shooting a "bullet" that "would kill people". :roll:

Don't worry, Miniboy is still being fired on the beach as planned, provided I can make sure no one else is in the firing line and the weather is good.

This is why I love people. :roll: The media is just as bad, if not worse than that. "Guns are bad! Guns kill people!" NO! Guns do not kill people, criminals do!! :banghead:

Okay so I wired everything up but the relay seems to be normally closed in that it disconnects when I activate the relay. I realise I said "normally closed" in my topic post but I was thinking in terms of valves :D

Apparently to reset the relay you reverse the polarity but that doesn't seem to make a difference, it's still powering the circuit until the relay is triggered.

Ah so maybe this is a normally closed relay because moving the 'power' wire for contact 2 to contact 4 turns the relay on and completes the circuit when activated. According to the spec .pdf, this is how it should work.

So Dewey, did I confuse you by asking for a "normally closed" relay when I really needed a normally open relay? If so, sorry about that. Looks like I can still use the relay at least :)


Edit: Oh and if anyone could help with this as well (couldn't find anything online):
Can I add antennas like the ones below to the transmitter to boost the range?

I was wondering why you wanted NC rather than NO.

Just drew what you wanted!

Here is revised to NO.

Perhaps it worked out for the best, at least it means I followed your diagram correctly :D

I'm starting to really like electronics, pity I didn't as a kid otherwise I could be a whiz by now! :wink:

Thanks for all your help and again, sorry about the confusion.

I know what you mean, almost every conversation with dewey provokes that feeling :?

It seems difficult and expensive, well for me anyway. The possibilities seem endless though, would be awesome if I knew how to use it.
