	The micro-cameras I think you are refering to are made by 
Panasonic.  They have several kinds, and one is the size of your pinky.
They are color systems with 430 lines of resolution (SVhs).
The smallest measures 15/32 inch by 1&3/8 inch long without lens.
Supposed to operate in as little as 5 lux.  B&W available.

	Now while the camera seems tiny, the pictures I have show a 
brick sized support box connected to it.  The camera in a pen is not
self contained.

	Call Panasonic,industrial camera for more

I can handle ordering parts...  I was looking through a few catalogues for
RF transistors and came across a flyer from Ocean State Electronics (as far
as I know I have no local place to buy cool parts.. hehe) and they had
advertised this transistor:

2N2553    $2.75
"RF Power Transistor"
NPN, TO-39 case
VCE Max=40v     IC Max=1A
PD Max =7 Watts FT=500 MHz
"Great transistor for QRP"

I thought that was wierd that they had something more than just the number,
purpose and price.  Looks pretty decent for $2.75 I thought.  There was
another "RF Power Transistor" right next to it for $21, 120 Watts... (hmmm)

Thanks for your reply, I tracked the problem down to the 12 volt wall power
supply.  It seems it is _totally_ unfiltered and that's just not going to
cut it.

I'd send you the schematics, the problem is, I built this thing about a year
ago... I have NO IDEA where they are...!  <grin>  Maybe I'll write them up,
the thing consists of 9 resistors, 5 electrolytics, 9 ceramics, 1 epoxy
dipped cap, a coil, trimmer, 15 turn pot and the 1404... not incredibly
complicated.

Something I would be very interested in would be a more stable oscilator, say
maybe a VCO with PLL chip?  They don't cost a hell of a lot either...  I just
don't know enough about electronics to stick it together.

A while ago I bought the D.C. Kits FM Stereo transmitter kit... it was quite
small, but it worked well for about 200ft.  (this is with a VERY noisy FM
band mind you..)  Then, I happened to come across alt.radio.pirate... "gee,
looks interesting!"  I've been reading this group for a few weeks and saw
the modification list for the FM-10 (and other BA1404 transmitters).  The
thing that caught my attention was the "power amplifier" section.  So,
I trotted down to my local Radio Shack and got the parts, put it together,
and didn't get it working... <grin>  When I'm listening to it's output it
quicky fades in and out.  I can't hear anything that's played through the
kit on the reciever, just cycling interference.

The BA1404 is being supplied with 3 volts, there's only a 10pf cap and a
resistor (attached to +) between the chip and the antenna output so I don't
think that the power amplifier is getting to much output.  However, the input
voltage is 13 volts (off of an AC adapter (is that a bad idea too?)) and I
read how sensitive that circuit is to the value of R1 (the 220 ohm resistor).
So, could it be I need a larger value R1?  Or should I just give up on the
idea of trying this without an FM-10?

Also, since I'm getting about 200ft non-amplified, I guess I shouldn't be
expecting the 1.5 mile radius in the mod listing eh? hehe

As a bit of a reply to your previous post asking about small TV cameras, I've

Well a couple of things to try here, first you have nano-watts comming out
of the BA1404 so gain is very important here.  I would use a MRF-901 for
the transistor and increase the value of R1 to between 270 and 350 ohms,
R1 should be larger according to how much input you run at the stage.  Gain
with the 2222a is much less than the MRF-901 or other hi-preformance
transistors.  Expect about 1 mw out with the 2222a and 7 mw with the 901.
The whole purpose of the amp design in the info sheet is that you could
get all the parts at radio shack.  There is soon to be an expanded amp
section covering much higher performace amps (but you may have to order
the transistors, and chokes. )


I haven't seen the DC kit schamatic, so I don't know how it operates.  But
the FM-10 also has a feedback resistor going back into the osc section, from
the output, befor the 10pf cap.  This also helps power output.

If you want to snail mail me the schematics I'll take a look at them.

I think this is legal.  There were a couple of pirate radio stations doing
this outside of England.  I don't know if they are still broadcasting.  It is
also the same concept behind government sponsored "Voice of America", "Voice
of Cuba", "Voice of Iraq" and what have you.  They just bombard a country
with powerful signal outside of their jurisdiction.  I believe that the money
spent on buying a freightor and setting up a pirate radio station off the
coast of America would be equivalent to buying your own legally run station.
In England where the airwaves are goverment controlled, this isn't the case.

     You may not have to build them if you do some hunting around.

     In the old days the cable tv industry used to be in the habit of jamming
watts down the head end of the cable and passively splitting it.  This was
before the FCC made them comply with rules and regs like everyone else.
Some of those old amplifers are still around (tubes), cover the full televison
range, are linear, etc.

     I experiemented with putting the output of a vcr into one, was able to
receive it, snowy but intelligible, about two miles away.  It was less than
ideal since neither the VCR or amp did anything about the lower sideband,
thus it was a double-sideband signal rather than vestigal sideband, but there
isn't a local channel two anyway, so no great harm done.

     Since the amp didn't show any signs of clipping, I don't think I was able
to drive it fully with the VCR.  I don't really know what the rated power
output of these things are, but I could put a 7-watt bulb on the output and it
would glow about half brightness (and that's really with a bad impedence
mis-match since it was designed for driving 75 ohm cable).

What is legal to do without benefit of license is very clearly spelled out
in Part 15 of the FCC regulations.  In recent years, these have become more
restrictive (the above example of a 4W pirate in the FM band is CLEARLY
illegal).  Also, the FCC recently "grew bigger teeth" - the fines permissable
for even first-time offenses have gone way up (how does $8,000 strike you?),
and the FCC is getting more serious about enforcement now that it can be
a real revenue-generator.  The short form answer is: don't try unlicensed
operation outside of Part 15 unless you're willing to take the risk of
MAJOR fines.

OK, I just replaced the 2 output stage transistors with at17a's.  I can now
get about 200mw out at 13.8 volts vs. 120mw with the stock transistors.
I am sure that MRF901's would work just as good, except that they may be
hard to mount on this board.

also note that output power @ 6 volts with the new transitors is about
100mw and 160mw at 9 volts.   Stock is 50mw and 90mw repectivly.

A heat sink is needed on each of these puppies, but they are in metal can
form so a piece of #12 or #14 copper house wire bent in a tight s shape
soldered to the tops of the transistors works great.

I just wish the video was cleaner, does anyone know if buffering the video
in would clean this up?

Also anyone know where to get cheap video cameras?  small ones?  I would
like to mount this in a remote control car and record while driving it around.

There's an outfit in Southampton, PA that deals in miniature cameras and
surveilance gear. It's Sherwood Communications Associates @ 
(215) 357-9065. As a 'for instance', they sell a miniature color camera
with 300 line res., min. 5 lux illumination that's about 3" square 
not counting the c-mount lens. They want ~$400 for it.
Alternately, you can get a mini B&W board camera (2x2-3/4x1") for
~ $195. Both operate @12vdc.

Subject: I need Turbo Pascal programming library for Sound Blaster

I need some kind of programming library for controlling Sound Blaster.
I am looking for a shareware or public domain programming library
for Turbo Pascal 6.0. I have most of the information how to contol
Sound Blaster, but I don't want to write all by myself if there is fre
source code available. 

I can myself program Sound Blaster D/A channel, but I have some
problems in controlling FM channels. That's why I am looking for
ready library that I can test some of my ideas.

I also appriciate Sound Blaster pro support. Also 4 operator OPL3
chip (used in SBpro 2.0) support would be nice.

There has been discussion about this topic in this newsgroup.
I tried to find some codes mentioned, but unfotunately those
codes had dissapeared from ftp sites I tried. I tried to get
/pascal/sbutil*.uue from hamster.business.uwo.ca, but it was
not there anymore. 

Any information appriciated. You can E-mail to me or reply to
this newsgroup because there might be may other who might be
interrested in this topic.
