Project Appeal

I was speaking with Chris Carpenter today and came up with the phrase/concept “project appeal” (I’m sure I’m not the first, it’s obvious)…

The 5mm LED version of the bili light has a lot of “project appeal” because the parts are so easily available and cheap, and because the soldering has that good “knitting project” nature to it- repetition in a good way, seeing something come together as you work. Is there a catch phrase for the concept of “good and creative repetition”, as opposed to the mind-numbing repetition of working on an assembly line? The word “repetition” has oodles of negative weight at this point, and I think it’s because of the assembly line, and the types of menial labor that come out of that. I have good role models in my family for GOOD repetition: knitting, crochet, spinning, weaving, all of these are very creative activities… in fact, it occurs to me that human creativity probably started, millennia ago, with these very activities.

Colin brought this up when we were hanging out at his bbq a couple weekends ago – the concept that the doing of the project has value, regardless of how technically correct it is or rather, perhaps in spite of the fact or even because of  the fact that the project is not something that an industrial production company would do. That’s part of the spirit of DIY: Do It Yourself because some mega-corporation is not going to do it for you, and if they did you wouldn’t want what they made anyway.

Anyway, the soldering of 120 or so 5mm LED’s has a lot of “project appeal”, and the question is: how to weight Project Appeal against a different project that might have less project appeal but better therapeutic efficacy?

I’d like to get the project to a place where you can have the best of both worlds, and with the MCPCB’s Vachik sent me, I can see how that might come together.

    • Good question!

      An “MCPCB” is a Metal-Core Printed Circuit Board.

      MCPCB’s have a metal core. Traditional PCB’s are constructed of copper plated onto fiber-glass or other inexpensive materials that are electrical insulators. However, these insulators are also thermal insulators. MCPCB’s have a metal core, which obviously must be electrically insulated from the circuitry, but is thermally conductive, allowing heat to be “sinked” away from the components mounted thereon. In the case of High-Power LED’s, the metal core acts as a heat sink or, more commonly, a heat conductor which carries heat away from the HP-LED’s to a more substantial heat sink.
