You are probaply and hopefully going to learn how to make some kind of heatsink for your regulators or transistors for pretty sure free. And if not, hopefully even getting some idea, of course you can modify my idea.
I think that it is pretty stupid when people says like "this is my first instructable, so try not to be hard on this one.." and so on, and I thought that I won't say it that way. So I said it this way ;) Be so rude as possible! No, not really just kiddin'. Think this as an instructable as others. And have fun and let's get started with the step one.

Step 1: Things You Will Need.

So you will need:

Some transistor or regulator, of course
Some pieces of metal, I had some washers
Drill
Some small bolt and nut

Step 2: Let's Start!

So next you are going to drill a hole to your piece of metal. Drill the same size the hole is on the transistor, or drill a bit bigger hole to both like I had to do, because someone has aten my drill bit that size. I'm not sure but it may be 3mm hole. Sorry I don't remember anymore, because there's been couple of weeks when I took those pictures.

Step 3: Screw on the Heatsink.

The title may tell you something about this step. Screw on the heatsink. But before that you may wanna sand the edges of the hole if necessary, I didn't have to.

Step 4: Some More...

Now you're done! Then you can of course use any size or any kind of metal. In the next picture you will see something that will have some potential to be heatsinks. Any metal will work. Have fun and comment what you think about this instructable! And tell me if there's some mistakes or problems or just any other question or anything!
you need some kind&nbsp; of thermal paste, otherwise it wont conduct enough heat...<br /> <br /> nice project!<br />
i used toothpaste
As I know, those commercial thermal pastes contain zinc oxide. Once I noticed that we have in our bathroom some lotion that is used to put on babies if they have some kind of diaper rash, and it contained pretty much of zinc oxide so I think that might work pretty well as a thermal paste. Gotta try that next time I need thermal paste. And I think it may be even cheaper than commercial thermal pastes.
oh yeah, baby powder contains zinc oxide
look at <a href="http://forums.overclockersclub.com/index.php?showtopic=164465">this</a> then, more tips on using household stuff as thermal paste xD<br>
Yes the thermal paste would make it even better. It will conduct heat without it too. Thanks!<br />
Copper and aluminum conduct heat much better than steel, so if you have the choice, use pieces of those metals.
