... You're exactly right. I'm not sure what I was doing before... I checked out other items they have and I was very excited to see some of their other products! They've got shrink wrap tubing and EVEN... USB A Male to open end wire. I can't even believe it... :biggrin: I'll be ordering up...

Every site I've found that carry these fans have minimum orders of 200+ or handling fees of $15 + shipping.

Sorry, I stopped getting notified of new posts for some reason. NoTime, those fans are PERFECT.:!) :!) As far as calculating airflow goes.. I'm not really sure how much airflow I'm going to need to cool off the heatsink. I am fairly familiar with about how much air a certain rpm will give...

hmm, I read through that PDF and found it pretty interesting. However, I don't think I'd be able to make a working circuit after reading through that. [sorry for double post]

Interesting stuff here... I was checking out the LM3224: InputMin Voltage 2.7 Volt InputMax Voltage 7 Volt Adjustable Output Yes Output Range Vin to 20V I'm guessing that's the sort of DC-DC converter I'm looking for. Looks good on the search page however when I add it to my order it...

When I put 5v (USB) through a 12v fan it won't even spin. I also tried 6v (4x AA), that also did nothing. I know this because I tried.

What's actually going on I don't think I ever posted what this was actually for. CAD renderings posted below. Copper heatsink with a rubber shell. Fans are inside pushing air through the grooves.

Alright, I do know that it is a very bad circuit. There are a few limitations of the project that have not been considered. 1) I am limited to power sources that portable computers have. Nearly all laptops have USB power and this gives consistent power unlike Firewire. 2) It is very difficult...

I was laughing at the word, that's all. And yes, after reading up on regulators, I realized they create heat. The whole project is to remove heat... that's why I took it out of the circuit. I have listened a lot to what everybody has to say, that's how I've gotten so far. Sometimes things work...

ab·hor·rent (b-hôrnt, -hr-) adj. 1. Disgusting, loathsome, or repellent. 2. Feeling repugnance or loathing. 3. Archaic. Being strongly opposed.lmao. I tested the regulator and it worked fine. However I learned that it drops voltage by converting it to heat. Removing heat is what I'm...

And the results are in The results are in... Check my circuit diagram and you can see what I ended up with. Any thoughts or final suggestions? Couldn't find a fuse lower than 250mA so I went with that. It may not be doing much but it makes me feel better

O_o :bugeye: erm.. :rolleyes: First off- that question doesn't belong to this thread Secondly- if you drive an ambulence that is equipped with a siren, you will already know how to change the lights. Thirdly- if you don't drive an ambulence, but have attached a siren to a vehicle... um.. yeah..

Yep, you are right. I forgot php pages show the modified date as the time you are accessing the page. heheo:) In that case the IF statement would work perfectly.

If it doesn't have both, look into a dazzle dv bridge: http://www.cwol.com/dazzle/dazzle-dv-bridge.htm It's got a good amount of inputs and outputs including firewire and NTSC
