Edmund Scientifics sale on

If you wanted some AC fan speed controllers, now's the time - they're $1.02 (figures I'd have all I need already)
Speed Control for 115V Fans
Note not for sale by me - just something I ran into...

bigben2k · 02-16-2005, 08:52 PM

Perfect timing... Thanks!

bigben2k · 02-20-2005, 03:27 PM

Ordered 3.

I've been eying this item for a while, thanks Bob!

redleader · 02-20-2005, 05:18 PM

Does that just decrease the voltage, or can it actually alter the frequency?

bigben2k · 02-20-2005, 08:44 PM

I'll find out when I get 'em!

(I wouldn't count on a frequency change though; it's a pretty small package)

Well? [Now post is at least 10 chars]

bigben2k · 03-15-2005, 03:03 PM

I got them.

It's a simple circuitboard, 1" x 1", wrapped in a clear plastic. Since you're interested, I'll pick one apart, and report results.

DrCR · 03-15-2005, 04:14 PM

Looking forward to your report as well.

bigben2k · 05-01-2005, 05:06 PM

Finally!

I've got a pic of the unit:

It's a rather simple circuit. Note the trimpot on the bottom left.

I'll try to run some tests shortly; I've got a spare AC fan begging for this.

DrCR · 05-01-2005, 06:36 PM

Awesome, thanks for the update.

bobkoure · 05-11-2005, 10:56 AM

Sale's back on - and $1.02 again...

DrCR · 05-11-2005, 05:13 PM

How did the testing go?

bigben2k · 05-11-2005, 05:26 PM

No testing yet. I'll have to slap something together tonight, for everyone's benefit, and report tomorrow.

That looks like the controller on which I did some testing for you. Look up my thread “Taming my Comair Rotron”. In there you will se the testing I did. It was near the end of the first page.

Brians256 · 05-18-2005, 11:16 AM

That would be this thread.

bigben2k · 05-18-2005, 01:07 PM

Yep, that's the one.

Sorry, I've been working on too many things lately to keep up with this. I'll try to make some time for it.

FuzzyFace · 05-18-2005, 03:43 PM

Thanks Brians256 I forgot to put the link in the post.

And yes the controller does change the AC voltage to change the RPM of your fan.

DrCR · 05-18-2005, 04:57 PM

Thanks for the link.
