Heatsinks for power transistors and regulators!

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

you need some kind  of thermal paste, otherwise it wont conduct enough heat...

nice project!

i used toothpaste

[godofal]

look at this then, more tips on using household stuff as thermal paste xD

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

Yes the thermal paste would make it even better. It will conduct heat without it too. Thanks!

Copper and aluminum conduct heat much better than steel, so if you have the choice, use pieces of those metals.
