I needed a desk fan at work.
I found a small discarded Telus traffic cone outside the office. I figured this would make a nice base.
I salvaged a seized 120mm fan from a server and re-lubricated it. Once it got warmed up it stopped making that noise (you know, that noise). Good enough for personal cooling I thought.
There is a stack of old and dying Cobalt web servers from the early 2000’s in the office. None of these will ever be used in production – or anything for that matter. Most have been gutted and the cases converted to shelves. There is now a box of old, but working, Cobalt 12v power supplies. These are cool power supplies because they’re small with a single MOLEX connector and power switch. Again, good enough for personal cooling.
