I've got some parts to build stir plates that I'm looking to give away. I believe there are 4 'kits' that are nearly complete but still need some odds and ends and to be put together as a whole. On top of that, I also have a small box of 12V computer fans that could also be used for building one. If you're interested in picking one up, let me know! This is going to be a first come first serve thing - I am trying to free up some much needed space and can't wait around months on end for people to pick this stuff up. Obviously I won't tell two people at once they can have something and have them race to my apt, but if you can't come for 2 weeks and someone else can get it tomorrow, that's the way it's gonna go! I have had far too many no-shows in the past!

I'm game

So... does that mean you want to pick up one of the 'kits'? If so, send an e-mail letting me know when you can come by.

If there are any free kits left, I'll grab one. Depending on where you live I can pick it up today.

Me too plz!

Sorry Paul - they're all spoken for now. If someone doesn't pick one up, I'll let you know.

I've still got some 12V fans kicking around if anyone wants some!

92mm w/ damper switch or rheostat?

and where can one find rubber grommets and the stainless screws that i can countersink into the enclosure?

RAE electronics might have some

Are they located in halifax?

I'm just giving away fans.. not any sort of voltage regulation. RAE is in Burnside.

I bought light dimmer switches to try and adjust the speed. Think these will do the trick, or should I go to RAE for rheostats? The dimmers were only $6, trying to do this on the cheap.

I think I paid less than $5 for a rheostat at the Source/RadioShack when I built mine.

I have some really nice brush metal potentiometers that are left over from building a DJ mixer. Did u want one?

Just a heads up, the $60 stir plate I got from OBK seems really nice! Works straight out of the box, adjustable speeds, nice heavy base. Can put on a demonstration tonight at my place. I'll let you know what sort of starter it makes in a couple months, ha.

Sure! I'd take two if you've got them, building one for LD as well.

Please, if you figure itll work. i have a nice cigar box that i will use, may end up looking kinda nice, though i'm still unsure if i will put ground effects under it yet

You will need a second resistor to create the voltage divider using a potentiometer. Also ensure the pot is adequately rated so you don't burn it up!

Also, to answer Chalmer's question, a dimmer switch is a rheostat (well, the old school ones that are inexpensive are - some of the newer ones use PWM), and would work fine - since they're meant for 120Vac use there's no risk using it for 12Vdc (though a 120Vac rating does not mean you could also use 120Vdc).

Guess its back to the drawing board for me

It's not very hard/expensive to do. The dimmer switch route is good, or I just went on Ebay and bought a computer fan speed controller from China for a couple bucks.

Also, for anyone interested in one of the free fans I've got, I'll have them with me at Tim's tonight.

Yes please if its 92mm or close to that, reason being i have read that for larger (ie 5L) flasks it's recommended

I don't know what size they are. The size really doesn't matter so much as the torque and RPM. Anyway - they're free. Either take one or don't!

got an extra hardrive magnet we can trade?
