What project shall I build with this?

irf630 am transmitter

Hello all!

I'm back again with a question about what to build with the few components I have, or at least be able to start with the ones that I have.

I want to build something for my hobby but not sure what. I am active in DXing shortwave and amateur radio, and also medium-wave (AM) radio.

I attached my inventory of parts to this message as inventory.rtf which should open in most word processors and write, notepad or wordpad.

SA,
If you want any one to replay plz don't attach a file like this, if it is pic you can show it here as an image or if it text you can write it here.
thanx

You can't build much of a radio from a handful of CMOS logic and slow opamps.
I suggest you choose an interesting project and start shopping from scratch.

To the 2nd poster (1st reply), here is the text contained in the file. Sorry if it's a bit lengthy. Well one of the things I've always wanted to have is a loop antenna pre-amplifier. Oh yeah, I was told once to collect all the data sheets on the components which I did and saved on a Zip 250 disk. I also was wanting to build a FM transmitter, or a exciter for a AM Transmitter. Anyone know of any good plans? I could also use other things too.

Well,
For an AM transmitter u can use the logic circuits to make an oscillator, but u also need a crystal. With this signal u can drive IRF630 as a PA, an modulate it on the power line. But this is illegal if you don't have a license!!!

7805 is a power regulator.

If you had at least a few small signal transistors (like 2n2222, BC547...), along with LM386 you could build a receiver.

But its better to buy parts for a specific project.

 

[gbowne1]

Cool! I also forgot to say that I found a Motorla MC6800P CPU chip in my collection too.

Well, yes, I know it would be illegal without a license. Don't wanna get into anything that isn't leglal, though I wanted to try some LPAM or LPFM some day.

It would be nice if I could have a filter for AM/MW and a pre-amplifier for my MW Loop antenna, a 30" x 30" square loop made out of 1/2" copper pipe.

Another way is to define your word scope and component you need then sell out the other component and buy the one you want.

 

[cyberrat]

How about an egg timer?

Us ethe 555 for the timer then have all the rest do some whizzy stuff with led's... lol

my first digital project is a touchless lamp switch using CD4013
