need help with stir plate build

Trying to build a stir plate with rocker switch and rheostat and DC computer fan all from radioshack. please help me with wiring it together. Thank you.

Do a search on DIY Stirplate

I have been. Nobody seams to explain the wiring to a rheostat they show eveything else though.

This thread should make it easy because it has lots of pictures.

I just built one. See the link in my thread for the wiring schematic. https://www.homebrewtalk.com/f11/just-built-stir-plate-336281/

Thank you everybody. I hard wired it so far and it works but, if anyone has a wiring diagram that would be clutch. Agian, thank you

Which link?

Here's the one I made, using an LM317:

Using a rheostat, the wiring should be simple. I assume you have an AC/DC power plug; hook one of the wires up to your fan, the other wire to the middle post on the rheostat. Put another wire from one of the outer posts on the rheostat to the other wire on the fan. If you want to add the switch, you can put it inline with any of the wires. Done!

I would like to thank everyone who answered the thread. my final result is great. thanks to you guys. i learned so much. i was going to leave the rocker switch out until cjb told me plain and simple i could just wire it in line. seems so simple now looking back at it. to anyone who reads this thread in the future, DONT OVER THINK IT. it really is as easy as you think. Again thank you all.
