mini telephone tone dialer?
Posted 04 August 2003 - 03:46 AM
for those who don't know, this is a radioshack mini telephone blue. It costs 1.97 here in 703 NPA and, in theory, could be a tone dialer. If you want to know, here are the directions, -in theory-:
1. Buy a friggin tone dialer, duh, there only like 1.97, if they're more, you know what to do.
2. Take out the fone cord that comes with it and cut an end off:
3. take the cut cord, strip (), and attatch a nine volt battery clip to the ends.
4. Now that the thing has power, instead of the mini speaker they give you, cut the cord used to go to the mini headset, strip () wires going to speakers, and attatch a new .25w, 8 ohm speaker or whatever is loudest for you.
REMEMBER, THIS HAS NOT BEEN TESTED, BUT SHOULD BE, I BELEIVE ITS A GOOD IDEA
BTW, pictures gathered from ALL OVER the internet.

DO NOT HOOK UP TWO BATS, IT JUS MAKES IT OVERHEAT, WITH NO VOLUME INCREASE.
What i am going to try next is screw the packaged headset and make my own, i jus need to get to the rad shack... ill report results later

well besides the fact that the hot glue might melt, you're going to have to go through the same shit again when one/both the batteries dies.
well, for real you could get like a case fan and stick it on there with some hot glue or super glue or with some zip ties or something and hook it directly to the battery and position it in such a way as to cool off the part that heats most.
have you tried different speakers to make sure it's not just a lack-of-power issue? maybe find a cheap hand helf am/fm radio that runs on a 9v or AA's or something and use the speaker from that since it's setup to run off that amount of power? just a thought..
good luck, let us know how it goes.

ok there we go..
you could try something like this
which uses one of these guys http://www.radioshac...LM386&pagenum=0
to build one of these http://braincambre50.....Audio Amp.htm
(which might be juicy enough to power a speaker at enough volume to pump out those tones)

You should be able to use a LM386 audio amp its a 8 pin DIP package. and the supply pins will take anywhere from 4V-12V and it puts out around 400mW @ 8 ohms. The only problem i see is that the if you increase the power output to near full the distortion can go as high as 10% compared to the average 0.2% at half power.
ill have to check some other typesthough. So if not this weekend then next i'll try to have this thing built.
EDIT: Oh well i feel dumb now dox posted the same thing almost ive really got to read before i post.
