schematic drawing

[kaukasion]

oh yeah and it said on the casing that it was rated @ 500mA output

which is .5A right?

so at 4.5 x .5a
its good for what 2.25W?
lol not much but something to play with
now i need to design and input stage and output stage
with as few parts as possible

this is one hell of a newb project lol

[kaukasion]

ok i just realized i have d1 and d2 backwards on the schematic lol

[dmfraser]

103 on a capacitor means

10 times 10 to the 3rd power.

More simply, 10 plus 3 zeros tacked onto the end of it or 10,000 pFd.

10pFd = .01 µFd.

By the way, to get the µ symbol, hold down the Alt key and type 230.

500mA is indeed 1/2 Amp.

[kaukasion]

well since i have this for a power suppy stage anyone give me some ideas on how to beef it up?

and or just use it as a cheasy little experimental amp

anyone know of any amps that would only need this sort of power
2 watts lol

an obstacle to creativity. They might be good for producing a
nice-looking final schematic for presentation, though.

Hi Christer,

Are you one of those monks that writes down an assembly program for a micro controller and then convert it to ones and zero’s by hand using pencil and paper?


Kaukasion,

If it is for drawing schematics only, have a look at DesignWorks: http://www.capilano.com/dwmlite.html

It was originally written for the Mac some 20 years ago. It is one of the easiest to learn programs with a nice user-friendly user interface and on a Mac it gives splendid graphic results. It was written by skilled programmers (not engineers) for engineers and with a lot of help of engineers using it. It is available for Windows also.

Cheers

HI Pjotr,

No, if I program at all nowadays, I prefer high-level languages. I did
it the way you describe with my first computer, though. I didn't even
have an assembler for it, so I had to write assembler code on paper
and then translate manually to machine code and enter that by
hand. It can be useful to do a couple of times as a pedagogical
exercise, perhaps, but it's not a very efficient way to do it on
modern computers. It was a different thing 25 years ago, though,
having only 16KB RAM and only a casette recorder as storage
device.

I have learnt over the years, however, that sometimes or even
often it is better not to use a computer at all to do ceratain
things. I don't know how much time I have wasted over the years
insisting on using computers for things that I realize later would
have been both easier and quicker to do by hand. Too much of
modern software is also rather an obstacle than a help to use
computers efficiently IMHO.
