That was a great compilation of information and circuit diagram Vortex, you should do it more often!

Lucky for me my $1 solder iron broke and the
$1 store has removed the long isle of tools ..
I broke down and obtained a real one at ACE.
WOW !!! :oops: heat makes solder melt !!!
I thought maybe I was holding my breath wrong.

I also broke down and ordered:
"Practical Electronics for Inventors" Paul Scherz; Paperback; $26.37
at Amazon.

I used a similar (not the same tho!!!)
relay from Advance auto parts, it charged?!?! the
batteries, but did not lite the neon under any
circumstances. Guess what, it had a "protection diode"
soldered in parallel with the coil! Imhotep acknowledged
that some relays have those, but for convenience, he
just tells us to get the RS 275-0001 relay and how to
modify it. Just a note for IRO users, and today we had
a new member sign up for Radiant Oscillator....

Welcome GLIDER!

Were you able to remove the diode?
If so, did your neon light up then?

NOTE: I've stated the neon is optional in previous posts,
but it is really nice to have when you hook up the wire
incorrectly because it stays lit to let you know that.
Labeling the connect points +/- source/charge helps TOO !! :o

Was it hidden away or easy to find the diode?

Thank you and I missed seeing your post above until now.
Been distracted I guess.

NO, took it back to Advance

YES, I got the RS275-0001

VERY hard to see, it is just under the coil, soldered in there parallel :oops:

You guys have been posting the wrong part number for Radio Shacks relay. it's 275-001 not 275-0001 http://www.radioshack.com/product/index.jsp?productId=3020762

ummm, I'll check, but I asked for a 275 dash double-aught 1 @ R.S.
and the package said 275 dash triple-aught 1 but perhaps I have
seen both... could be a typo I suppose, or I did not have my
old man reading glasses on :oops: :lol: :oops:

If -0001 is wrong, my bad, I started that. But asking for availability
on the phone, that part number has worked. :ugeek:

THANX V!!!

glad to see your not the only novice here mate :D
i too am a little stuck with this stuff.fortunately i am a fast learner even when the so called easy instructions are a bit dodgy for a novice to follow.

persistence is what keeps me sane :twisted:

i was originally thrown off by imhoteps drawing as the top wire is called 87 a.
my relay had an 87 a connection and i accidentally was using that.
but it was the top wires wrong markings . top wire is the new added wire .
though this was simple enough to work out on my own.
just have to think about what it is exactly that you are doing wrong.
instead of 87 a it should have been called something like 87s new connection point.

Hi all. I modified the radioshack relay and had it working, but it stopped now. (scratch head.) Has this happened to anyone else? I used a solar cell to power it and was charging two AA nimh batt. Left the room and came back about 10 min and, gonzo. Is this bad luck or did I do something wrong? P.S. will or does the neon turn off when charge batt is connected. Mine stayed on.
