Very entertaining and useful, Tangent!

I was half joking when I suggested the epoxied penny. I don't think it's a good idea. |
Although the contact area would be far from optimal, it's a lot better than a paperclip. |
And then the thought of the paperclip falling off, and landing somewhere around the legs of the reg... |
Of course it's best to buy a proper heatsink |

Does this really matter since I will not be using a fan, so I will not have any air velocity (see the graphs for the part above) 2.) Is there another heat sink that would "fit" on the TREAD? The larger style used on the STEP doesn't look like it will even come close to fitting!! Thanks! |

I forgot to attach the heatsink... and it swung to full voltage output... luckily it didn't do any permanent damage to the valve or the regulator. |
