audio recording on IC -help wanted

[m.a]

Hello,

I am looking for an evaluation board that has an MCU (preferably low
power) and an ADC and UART.

I want that I program MCU in such a way that when it gets a command from
UART, it get 1000 samples from ADC and place on RAM and at the end of
capturing sending them to another system via UART.

speed of transfer to other system via UART is not important ( I have several
minute to do so).

ADC sampling rate should be 100KSPS.



Any help in selecting a suitable evaluation board is very appreciated.



Regards

er... why?

So it looks like you're working instead of staring at an
empty desktop (which could seem either a bit suspicious or

Ah... I see I can learn a lot from you folks.

Two problems I see:

1. All those icons on top of my Word File (I guess I *could* hide

2. Boss might get suspicious... "Are you STILL working on THAT

That's a good idea. Although I did give the uC board a good whacking
to see if it would fail again.


That's bad technique--whacking is what fixes things.


Ah yes! I remember, Archie Bunker in "All in the Family". Whacked his TV
to make it work. Then one fine day ... whack ... phoooieeee ... phssssst

Freeze spray or flexing, pushing, and probing the PCB with
fingertips finds most intermittent connections for me.

But if whacking didn't break it, try a bigger hammer.

That's pretty bad. I've been using leftover Toshibas, and they last

I bought 6 smoke alarms at once, so I went for cheap ones. 99p on ebay
I believe.

Oh, *that's* a smart move. Expected though.

I did of course test them. They detect smoke perfectly well.

True, you can still get 65C02's and 65C21's. It's the 6532's
that I have trouble with. Finding reasonable, unused and
non-counterfeit ones is getting touger and tougher. I tried
to talk them into making 65C32's. Sure... just ante up a $10K
upfront NRE... yeah, like a hobbiest can do that.


6502.org have an account at WDC and have done group buys there.
I doubt they could pony up 10 kUSD worth of orders, though.

That sounds like a potential business opportunity. If you are really
sure that there is enough of a market you could talk to them about it,
see if they'd support a "vintage processor store". Heck, you guys sell
very tasty 30 year old wine, why not processors?

You could look for Roy J. Tellason's page. He has lots of 65xx

Hi,
I am using 3 x 100 ohm SMD resistors connected in parallel fed with a
12 volt supply to make a small heater for a device.

I have calculated that the resistors will give a total of 4.3 watts.

The surface area of the resistors is 61.44 mm2 (6.4mm x 9.6mm)

Is there any formula to calculate the temperature that the resistors
will reach?

Thanks.

No. You'd need a very complex model indeed to predict thermal coupling for
an SMT part in almost any context. This really IS one of those things best
done empirically. If anyone posts saying different to this, ask them how
they're going to quantify the thermal coupling when they don't know your
board, your solder fillet profile, ambient conditions, etc...

What you can do is look for a manufacturers figure for thermal coupling,
hopefully given in the °C/watt rating used for heatsinking. They might
specify some conditions you can use as a guide. None of which is a substitute
for the test you'll have to make anyway, by which time you'll know all you
need to know.

Hi,
Thank you for your advice....I did think I was asking for the
impossible....trial & error it is then...

Regards.

Both do. It's called infra red radiation.

There's also conduction too.


Agreed that *should* be the case, but the fact is that the envelope of a
vacuum light bulb remains substantially cold in use, whilst a 6L6's

What lighbulbs have *vacuums* in the bulb ? It's normally filled with a

Add uP or properly muP to the decice type if NEC


some related info from one of my tips files below

On transistors marked C???? read 2SC????,similarly
A????-2SA????,B????-2SB????,D???? read as 2SD????.
Also ICs marked A???? can mean LA???? (Sanyo) and
B???? can be LB????,C???? can be LC????.
Also C???? and PC???? can mean uPC???? (NEC,for u
read mu) and D???? can mean uPD????.
On Sony ICs of the 70s and 80s marked with 3 digit numbers and no
leading letter such as 174A and 174-2 read as CX174A and CX174-2
Motorola MC14??? usually you can drop the 1 and then read remainder as
normal CMOS 4000 series number.
Signal diodes with one wide band followed by 3 coloured bands ,
one convention, eg
wide red , black, blue,red may mean the last 3 digits of the
type is 062, in this particular case 1N3062

On one of my long-ago jobs while in college, I once used a standard
Craftsman screwdriver to tighten a LIVE but loose 480 3-phase
connection.

I survived. But only later did I stop to realize that the plastic was
probably not rated for any kind of voltage, much less anything in that
range. I get nervous just remembering. Methinks God protects
fools....

The plastic might have been enough actually, but I'd have been anxious
about a sudden lowering of resistance in that connection while working it,
if there was much current flowing. It might have melted explosively at you.
I once tried to reconnect a 240V 100A AC line (with no accessible upstream
switch) not realising that immediately downstream there was a full short
circuit caused by an earlier accident. There shouldn't have been, a pair of
100A terminal blocks takes a LOT to melt down and fuse together that badly,
but so it was, and on applying the connection, it swore at me the way only
a high energy short can (people several rooms away heard it shout), and it
sputtered my eyeballs and the skin of my face with a nice copper vapour
deposition that took days to grow out entirely, and itched fiercely most of
the time. For the first tem minutes I was totally flash blinded, and I was
in nervous shock (not electrical, I took care to at least get that right)
for several hours. Had to attend a science project that evening too, that
was no fun, it should have been, but all I wanted was a dark and quiet
place to rest for a while.

And the weirdest thing of all was that I did it TWICE. The nervous shock
set in instantly, I was so confused I pushed the cable in again as if it
would have worked right the second time. You have been warned! The nervous
shock alone will scramble your system so badly you'll do something wrong
again before you react sanely enough to start doing the right thing. I was
lucky enough to remain on my feet, on a chair I was standing on without
falling against the wall or worse, and had no permanent injury, but I think
fate gives us single warnings on stuff like that. We have to heed them.

You were very lucky you didn't get a belt from it as well ..I had one
many years ago when I couldn't let go, and it was fortunate that someone
was nearby who did notice and realise what was going on..

I still remember every microsecond of it, the pain was excruciating I
couldn't move anything just this loud humming and my body violently
shaking(

Jeez, you guys! When I said "I survived", I meant "nothing happened",
as in "I got away with it totally dude, no sparks or nothin'"
Your stories make me nervous all over again.
Maybe that's why most of my electrical career involves 5, 12, maybe 24
volts most of the time. I have cheap screwdrivers.....

I have a motor home which has the main battery for the engine and an
auxiliary battery to supply the lighting etc in the living area. With
the ignition off a relay switches the auxiliary battery to supply the
living area but when the vehicle is running the relay connects the
auxiliary battery in parallel with the main battery so that it is
charged. The circuit is badly designed because if the auxiliary
battery is flat and the main battery is fully charged (which it always
is) there is a very high current surge from the main battery to the
auxiliary which blows the 30A inline fuse. I, therefore, need to
insert a circuit to restrict the current to say 20A max.

Can anyone say where there is a suitable circuit diagram on the web?

Thanks for all the ideas. An isolator is the real answer and if I was

designing it from scratch that is what I would use but the relay
serves as an isolator albeit a very poor one. I had thought of using
a resistance to limit the flow and the bulb is a good idea but I am
concerned about the heat generated in the small space where the
circuits are installed.

For info. I have draw a wiring diagram of the circuit, as it is, and
put it here:

http://vanwiring.hobby-site.com

I had thought in terms of a simple circuit using a 2N3055 with a zener
in the common base circuit and if you scroll down below the wiring
diagram on the web site I have sketched what I mean. Anyone any ideas
about this one please?

The Osram 23W in the kitchen is original and eight years old. It doesn't
do so many hours but it does get switched on and off very frequently.
So I am not convinced of the argument I occasionally see that on/off
cycles kill CFLs.

** It kills the ones that are designed to start and reach full output very
quickly.

The heaters are run hotter in them and have high initial current levels.

Many independent tests have been done to verify the destructive effect of
many short cycles and it IS true.
