Homemade Filter Fan Distraction
January 22, 2012
I was crusing YouTube and saw a few videos on these homemade filter fans from Altoid tins. I don't have a fan system since I usually just do my building on the kitchen bar area, so I thought this would be a good idea to build. After watching these videos and finding out that it was some article in Make magazine, I breadboarded the circuit and wrote down the diagram for the project.
The Filter Box
After a search through my parts and found that I had all the necessary items except for a box to contain everything. I then noticed one of the boys card boxes and quickly decided to use it for this project. I might have to do a quick paint job in the future. Here's the front side.
With the back side, I used the fan cover that was with the 12v fan from an old power supply. It looks pretty snazzy.
Finally a look at the internals. I know, not very pretty, but it functions well and I'm a little proud that I could actually get the thing soldered and working properly.
The only thing I think I want to do is find a fine metal mesh to put over the fan on the inside so the filter does not hit the spinning fan, slowing it down.
I need to put the fan close to the soldering area but it works fairly well. With the charcoal filter, it sucks in about 90% of the fumes from about 3 inches away.
