Just an update -

I got the LED working last night. I don't know why it's working now, because the configuration is the one that sparked. No sparks this time, and everything runs fine.



The potentiometer won't turn the supply all the way off. If you want a slower speed, you could piggy back a second behind it.

Later,

I would not suggest doing ANY wiring while your power supply is plugged in.

I'll have to add a disclaimer to the beginning of the thread.

As for the potentiometer, it will NEVER turn the power all the way off. Regardless of the type of potentiometer, you will only get a voltage DROP by using any type of resistor. The potentiometer is meant only to allow you to control the speed of the fan, which in part allows you to control the speed of your stir bar and the size of your vortex.

Great instructions, got my prototype working last night. Need to do some soldering this weekend. Big Thanks.

One question, i see you soldered your Pot, but you used the connectors on your power switch, should you not solder a power switch? Will the heat burn it out?

Thanks!

Radio shack should send you a free project box for all the buisness you send them

Hehe... thanks. I soldered my pot because I knew that I wasn't really going to be moving it around. I used the female connectors on the switch only because it was easier. Normally I would always solder and shrink wrap an electrical connection.

+1 to solder and heat-shrink. Another +1 to your earlier post stating to only work on wiring with no power supply plugged in!

I drool a little each time I come to this thread. I'm itching to build this but I just have too much on the proverbial plate to build the stir-plate. Can't wait though!

+2, I used clips as well on the on/off switch for the same reason as Tony, but my soldering skills have deteriorated to the point where I couldn't get the heat shrink tubing over the big a$$ glob I created. I either need to improve my skills or buy larger tubing.

That's easy enough to fix if you want to, just grab a little bit of solder wick and pull off about half the solder you put on. You should still be able to see the outline of the wire with the right amount of solder.

I agree, but excuse my ignorance; what's a solder wick?
