Today, I prepared the final face pieces for the ventilation system. I still have to cut some tubing but that's really not going to take long with my angle grinder. I use two tools for cutting most things - either a circular saw or an angle grinder. So, today I cut out the final octagonal surround for the outside of the vent. I still have to trim swarm though. I also trimmed the internal wood for the internal side. I would rather have used aluminum but I didn't have enough and I'm certainly not buying more materials!
Meanwhile, I've been reading up on CPU fans. It seems that they mostly displace 25-90 cubic feet of air per minute. I don't know most of the specifications of my fans but I'm guessing about 50 cubic feet and about 130ma power consumption. It will be interesting to see how much air is shifted by both working together. It will be more interesting to see how temperature is controlled too.
I tried my solar panel on the fan that's installed. It really didn't blow as hard as on batteries. Even on freshly charged capacitors it didn't run very powerfully. I'm just getting the feeling most of this funky, fancy electronic and electrical stuff is just garbage. Well, we'll have to see how it all works out.
