Nice built!But you really should have a resistor on each LED (+/- 220 homs) so they last longer and light-up better.Make sure you don't exeed your arduino's maximum amp' per pin.

Rasp' will be cooled by aluminium water-blocks. One small block for the chip under the board and a bigger one for the two on top and the block will be high enough to reach the chip under another rasp' stacked over, and so on. I plan on doing a nice acrylic manifold but still at the R&D department..

What about calling it "Simple Cavitation Machine"?

"Some would ague that aluminum is bad (...) it has a food grade varnish coating"Not only this is more than a pretty darn good point, it's a way of thinking. Taking account of the primary use of the material you choose, it may have some differences on it's final & overall performance. As an example, I've tested hundreds of 2L softdrink bottles and they always been able to hold 130 PSI...I just learned something here.

From what I see here, it sure can be done.I think the author stayed focussed on doing the important things first: eating raspberry pie.(send me an inbox msg when you're ready to conqueer the world 'cuz I'm in, dude)

What about temperature? Does it get much hotter?

Here's said pot' current adjuster screw...for what I know.What are you making?

After spending 2-3 hours browsing for a working solution, I read your instructable.Beside the page of the driver being in a language I don't understand, I managed to get a working driver for my "I think is real" NANO V3 (atmega328) wich I installed with it's installer straight from the downloaded files.It worked within seconds.You rock. This is worth much more than a simple medal: I'd pay you a drink. Or two. :)-a very happy man.

Since you have 3 sprockets on the front, you must keep in mind that the chain can't handle the "tweak", the angle.. And the gear ratio you get from the small front sprocket while on the small rear sprocket is not a goog deal, sort-of.. You will get the same gearing ratio with the middle front and middle rear... get the point? Ok, tehy say it's "21.. 24, 29 speeds".. My a*s... You can't get the system to work properly if the chain have to "twist" passed some point, angle. Go ahead and try, but it will always mess up or loose it's tuning, even if it's a Campi'full-aces-Tour-De-France-Turbo-Sh*t edition. So do your tuning with keeping the chain in a straight line in mind and shift within these "limitations", sort-of.This instructable is pretty straig...

Trial & errors, feeling & logic should be yout guides. This instructable is pointing the vital points, the real basics (wich is 99% of what there is to understand).Follow the steps, look, be logical and ride accordingly to the 'untolds' mechanicals restrictions from your system. It's different to each bike but the principles are here 110%.Ride hard, have fun.

..Then I clicked on the link "go here", it openned another instructables with another link "You can find out more about judging a contest here." and 'round we go...What am I missing here?

There is another great instructable of a maze made of wood, much more elaborated than this one and the result is pretty impressive. Very nice wood working. I'm not linking it because there's a lot to be seen while searching for it!

Nice work! Yup, very nice! Thumbs up!

Ok I reassembled it to check.. .. not really.. but.. warm.. or hot..?.. I did'nt noticed that before your comment.. I think it's the resistors on the board that gets hot, my fingers are too big.. But all in all, this circuit is simply a variable resistance with a reff. resistance.. And it's a next to zero amp value..

"the temperature will rise when switching + & -... did you feel how hot the sensor becomes then?".. I said I did'nt..."I have no clue why you would wanna do that... to melt the pcb? lol Just dont do it.."..What was your question/point, please explain I don't get it.. ;)

No, not at all.. It did'nt do much with this, I ripped it appart the same day. One of my first arduino project, so when it worked, I changed project. But why would you invert the + with the - on the thermistor?
