Wink O2 Case - in LEGO!

Here's the result of a quick experiment to see if it was possible to make an O2 case in Lego. The end result is quite robust, and I'm pleased with how it looks. I haven't yet tried fitting the electronics, it will need to be glued togther first, and probably a little internal machining to clear the taller components. Anyhow, here's a couple of views of it so far. DSCF1296.jpg DSCF1298.jpg

that is a great idea! did you consider using tiles for the front to hide the studs?

I think I'll probably just mill the front flat to take the studs off, I don't have any Lego pieces that are just flat plates with no studs.

If you mill the studs off you might end up with little holes in the front from the mold, If you do not have the plates I could send you some, if I counted correctly the case is 4 x 16 studs? PM me your address and I send you 8 white 1x8 tiles for it

And let the LEGO-dealing commence ^^
I actually like the idea.

But mine will be hard and strong, machined stainless steel. A man-case, so to say :-)

Exactly.

Sometimes music is best served just like love: dirty and intense.

Best regards,
Jokener

P.S.: Love does not require you to fight with a CAM-application to mill it in only two steps!
Well, at least not in my world.

This was really nice first soldering job Only thing I had problems with was I soldered all three legs of U6 together I needed like half an hour to actually correct that mistake. Oh yeah and I didn't have any good clips so it looks a bit messy.

After some testing with old earbuds it seems to work well. Now before I put it in alu case. Just need to find some alcohol and clean the board because its dirty after all that soldering.
