That 2mm uses at least (2335 + 2235) * 2mm * 1mm = 2,280 mm^3 more material for the case. (a wall thickness of 1mm)

I don't understand your math. The 1mm (the wall) was there already, so why is it being counted here? Plus, multiplying by 1 doesn't do anything? Also, the 2mm extra won't be solid plastic (they'll be solid air, since that's why we're adding the extra thickness, for the room. If anything, the extra material for the case would be the perimeter length times the perimeter wall width times the height.

    Ah, thanks, I think what happened was that the asterisks were turned into italics and confused me. I think the message was edited to clarify.

      The post was fixed about 30 seconds after making it - due to the *s being interpreted as italics. It is a shame there isn't a preview button when composing posts.

        Or just more sane markdown handling :/

        I've started multiplying with "x" here... 10 mm x 10 mm = 100 mm^2.

        Although there is a "clear" way of representing the functions, I have come to think it might not be as clear to many people. For instance (3m+5m)(2m)/(2(2))=5m^3

New Feature: Delay - https://news.ycombinator.com/item?id=231024 https://news.ycombinator.com/item?id=231024 There's a new field in your profile called delay. It's the time delay in minutes between when you create a comment and when it becomes visible to other people. I added this so that when there are rss feeds for comments, users can, if they want, have some time to edit them before they go out in the feed. Many users edit comments after posting them, so it would be bad if the first draft always got shipped. Delay is initially 0. The maximum effective value is 10. It only applies to comments.

        This is fantastic info, thank you. I've now set mine to 5.

  That may not even be where the devices are most toxic to the environment :\ How about all the energy waste for manufacture of what are "engineered" as effectively disposable components & assemblies in numerous facilities? Also scattered local emissions, not only at the factories and delivery ships & trucks, but consumers kick up all kinds of exhaust and waste just earning the money to participate in such a scheme. And way more so for short-lived products that are the least bit overpriced compared to how they could be from the same factory.
