that would be great!! if you can box them i can send FedEx to collect...

 

There are some biggish items, boxing them up would be a pain,
If you and a friend would like to come and pick out the stuff that interests you, that could be arranged.

 

Ok, What sort of things are they?

Im intrigued

 

That transformer looks a bit small.
there are a few good supplies readily available. You do need to figure out your power requirements.
A good supply can be made from a PC supply. Google will help.
eBay have some interesting regulators. I recently have got one of these...

But have not set it up as yet.
For high current, a switch mode supply is better as the losses are less.
It is handy to have a number of supplies at set volts, as well as a variable one.

One like this will be good.

 

They are all the components that a electronic company would use
If you wish check my Profile/Information on this site.

 

ive found a 32v 1.5a power supply lying around, can i use it with the existing componants??

Im mostly only going to be using it between 6 - 12v in reality.

That sounds like it could be a HP printer supply.
So you have 48Watts to play with.

If you use a switch mode regulator with enough i/p volts rating that would be a good supply to use.
have a hunt on Ebay. There are lots there, and just make sure the regulator can take the input volts.

This one will let you get about 2Amps at 24V.

Limiting the output to 12V, you could get about 4Amps from that 32V supply with a suitable switchmode regulator.

 

Yes it is a HP power supply! Ill give it a go then.

Just make sure the reg you use can handle the 32V input, preferably higher! And if you go with an analog one, like the LM317, you will run into a lot of heating problems, mainly with higher current and low output voltage,

 

ive got the LM317 already so intend to use that. A big heatsink then!

 

Yep
That will be a good starting supply. many people have used the LM317 like that.
You could add one of these...

There is also one with volts and amps available there somewhere.

Do you have a multimeter? If not, these are EXCELLENT!!

A good multimeter is a must to help you develop electronics.
And this too.

Its ok i have a fluke 115 multimeter

tHIS http://www.minute-man.com/acatalog/Multi_Voltage_Economical_Power_Supply.html is pretty cheap and cool for a power supply, It is basically an LM337 with fixed voltages and a multi-tapped secondary, so it keeps the power dissipation down. I'm not saying it's the greatest thing in the word, but it's linear quiet supply. It's found on ebay too.

You could still build your regulator and get better control of your varied voltages, but you might not need it.

Right now, 3.3V, 5V, 12 V and 24V are common fixed single supplies.

 

i would like to add a constant 12v supply from this circuit as well as the variable, it will be to power a heatsink fan. How would i do this please?

I will be using the 32v 1.5A HP power supply for this.

 

VR1 is actually 5K

 

Hello,

Why do you want to waist so much power?
A switching regulator will be more efficient.
On ebay, you can get them:

For powering the fan?

 

Hello,

Why not use a mains fan?
Then you would not need to bring the voltage down.

Bertus

 

A switching regulator is quite ok for a fan. And running a 12V fan, not mains, makes sense. No mains wiring needed and that is a good thing.
I'd go as far as to add a couple of those switching regs, and have a 5V USB power socket as well as a banana plug post to the 5V.
And a preset 12V for the fan with another banana plug post.
And finally, have the variable output terminal.

 

thanks, i have a couple lying around so i will use one of those
