Since everyone here seemed to like my Pegboard designs, I figured I'd share this as well. When making the Only Sensor (see the home automation community or my site), I used this Solder Fume Extractor to keep my lungs nice and clean.
Fully 3D printable, and a full bill or materials on the link. Enjoy!
Hrm, not sure why the image returned a logo, but here it is:
Nice I've been meaning to build one of these but solder so infrequently that it's not at the top of my ADHD list.
One critique here is that your power jack is not rated for the amperage you're putting through it. Those black and green connectors are only good for 2-3A (even the listing says 2A). I have found that these work really well and claim to be rated for 10A.
Also if your fans are only 2.7A each and the controller is 5A, there's no real need to get an 8A power supply, but this is nitpickey and doesn't really matter either way other than a small additional cost.
All good input, I'll make some updates, thanks!
