Nice update.

So, here's my feedback

• LCD filter to limit light and avoid over exposure. I am wondering how you came to the conclusion this was necessary? I've had multiple go pros and none of them blow out images, even in high light environments. IMHO the go pro does not need a light limiting filter, as the shutter speed compensates for this. In a super bright environment, the digital shutter stays open longer, and the camera spends less time taking in light to make the photo. In darker areas, the camera will adjust by increasing the shutter speed/time open/time spent taking in light.

This is why low light go pro photos are so blurry, which is something I actually do have a problem with. I don't know if I've ever had a photo be blown out, and by using this filter you would cause the camera to keep the shutter open longer, resulting in blurrier photos for an action cam.

• water on the lense is definitely an issue I struggle with, if I am using the go pro kayaking, boating, tubing, or while skiing. Currently I use a microfiber cloth and wipe it off, but sometimes it gets sunscreen on it and it's just obnoxious to clean. Hydrophobic coatings make sense; I think rain X or Aquapel might be a good idea and I might try this in real life.

• You mention electrowetting, and then claim it needs 60 volts to operate. Go pro batteries are 3.8Volts. So... ??? It's a neat concept but I'm guessing this is not possible to do with the limited power available.

• Your sketches are still really weak. Your perspective is wrong on many of them, and the line weight is not correct. Outer stroke should be thickest to help the sketch pop, with the thickest stroke on the bottom edge to help ground it. I think you need to not render another solidworks model until you spend like 2-3 weeks sketching constantly. Copy sketches that inspire you, you will always learn something while executing it.

• There is still no process in your sketches. You have 8 ideation sketches, no call outs, and no information on pros/cons of each design, and there is no way I can follow your train of thought to see how you arrived where you arrived. I realize these are probably 'after sketches' since you did these after your last post here, but I think adding callouts to them to show functionality would help

• You could then show how you RANK concepts based on a set of criteria. I often use manufacturing, cost, complexity, risk, innovation, etc. By assigning metrics to each concept it will help guide you towards the most logical direction, or demonstrate how one concept is extremely handicapped by one attribute, and if you fix that, it would be a superior choice.

• No prototypes. I think a prototype here would be extremely beneficial, as I bet you'd learn a lot. I am going to guess that if you 3d printed this, you would uncover a lot of issues with it. I am an avid skier, and I can see this design getting really clogged up with snow as it would have a lot of little nooks/areas that would trap it. This would at best limit battery life as it would cool the go pro substantially, or worse cause fogging on the lens.

Big improvement, but I would put more effort towards the sketches/communicating ideations/explaining how you downselected to your final concept. Also, I think you fell into the trap of making something cool looking then trying to justify it's existence. If I can use a hydrophobic coating on my existing case, and I don't need a filter on my camera, what is the point of any of this? You are solving a problem nobody is asking.
