anyone build a simple amp for me?

Several, in each of the mags, I'm sure....

The only thing they would need a bug
for is any private conversations in your house.

Yep, they do that to special people like Herc.

But does he have friends that visit, or is it to listen in on his
conversations to himself?

I think that says it all.... your brother has finally woken up to your weird
personality and wants shot of you. Unless he is of similar ilk and off in his
own fairyland.

BTW, do you have a real job working with real people? And if so, what is their
opinion of you and your "voices" emanating from everything electronic?

I ordered a manufactured one, but that reminds me I'll order the Oatley kit now.

They hear my thoughts via the satellite, and get told what to say via satellite
to abuse me. Last month I walked in the hospital and out and people
yelled abuse 50 times in 5 minutes. I was going to take my voice recorder
it might have got it, would have been classic.

Yeah eg: one of the talking electronics bugs books has a directional mic
project that could be reduced to that (omit the accoustic hardware).

No one here can design a circuit? My brother would get this running
in 30 mins in a jiffy box.

He hasn't answered my emails for a few months. OK since you have to
design and test a new circuit, though you can probably look one up, we
can go over $100. You can't use an IC though. Intel might sneak a little
radio receiver in there and cancel their signal. The Truman Show will be
going public soon and you'll all wonder why you were so blind to the
truth.

Herc

You can make an extremely simple high gain electret amplifier with little
more than a TL431 adjustable zener.

The amplifier will just about directly drive a 35 Ohm speaker but it would
run cooler and be better for battery use with Rl = about 2k

Connect the electret from control pin to GND and Rl from K to Vcc, use a
variable resistor (at least 47k) from K to control pin to adjust the
operating point (subtract 2V from Vcc and adjust for 1/2 the remainder
across Rl).

This resistor gives you a large amount of negative feedback which stabilises
the operating point, but you have to tap this resistor at about 1k or so
from the K end and shunt the tap to ground with an electrolytic about 100uF,
this shorts out the AC nfb giving the amplifier a huge AC gain.

You can use a simple audio amp chip to drive a speaker or couple it into the
inputs at the back of the stereo.

I have theory about signal induction on the auditory nerve but it would
require a 2.45 GHz radio signal such as that used by bluetooth and 802.11B
and G as well as microwave ovens.

You can cleanse the signal from anything affected by zapping it in the
microwave, anything that doesn't fit - jam the door latch interlock switches
with a couple if plastic forks.

Not only that, a couple of ovens here and there round the house
with the doors propped open with a stick will jam the signals
from all the ZZZT! BZZZZZTT! CRACKLE! CRACKLE! BANG!.
