Hello people! (P.S. If someone can tell me why there are showing only links not whole pictures or thumbnails please give an advise.)
It hasn't taken a long time as I am here with another McGyver deserving project.
I made DIY cool tube previously but my bathroom fan was too weak to cool it through carbon filters. So I had to find one more powerful blower.
My first idea was to use radiator fan from some car and build a shell around it to make it as an in-line fan. But then my brother suggested to use heating blower. We had one from Audi 80 in our garage.

It had a bit broken shell but we fixed it quickly by soldering the plastic.

The main objective was to adjust it that there could be connected carbon filter and ventilation tube at another end. I had bought plastic wall attachment for 100mm tube

We soldered the plastic parts to the fan shell that it had enough area for 100 mm tube and there were no leaks.

Next step was to attach the tube to shell. we started by soldering but afterwards we discovered that burning plastic nicely melts together both parts and makes them as one. Almost welding.

There were another hole for some reason in the shell so I had to close it as well using the same technique.

Filter attachment was another thing to think about. I had two brand new 160mm carbon filters from cooking hood (afterwards I discovered that they don't remove all the smell, but that's later.) They are round but fan shell has square hole. I took a wooden plate and sawed an exact size square hole there with jigsaw. Attached it to the fan with wooden screws and used sanitary silicone to calk the connection.

For the filter I took another wooden plate and milled a 160mm hole using a pre-made template for 160mm holes. Then glued the filter to the plate and screwed both together. Used silicone again for the connection.

Last but the most important thing to worry about was to ensure the right power for the fan. as you know. car stuff mostly works on 12v. The switch has different resistors to dim volts for slower speeds. Pure 12v is the max speed and it can blow your plant trough the filter so I had to make it run on lower volts. As I didn't want to order special transformer, one my friend suggested that PC power block has quite strong power on 5v. The fan has 30A fuse in car so it means it works with 20A strong power approximately on 12v. That means that on 5v it needs not more than 10-15A. Usual 5v phone chargers and similar stuff works with some 1 or 2A max. But 250w PSU gives out 25A. That is the thing that I need.
Next step was asking to my friend Google how to fire this PSU without MotherBoard and it gave the needed info in first finding.

Last thing was to connect those wires and attach the fan to my cab.
So I have quite powerful fan for 9 EUR (the price of PSU) Not Bad! And it is so silent on those 5v. That PC coolers in my cab make bigger noise than this massive blower.
