I don't think that these are instructions that anyone really needs. I just wanted to tell the world that it could be done.
Step 1: Remove the case from your thumbdrive.
It's pretty simple. Just find the seam and poke and pry.
Step 2: Cover all but the USB Connector with Polymer Clay.
Step 3: Bake
Step 4: Some thoughts that aren't really steps
On the ones I have the LED is useless. It is lit whenever the drive has power. I don't know why they even bothered with it.
They do make translucent versions of the clay but they aren't really clear. I may try just using a glass shard as a window in future attempts.
One last thing. I doubt anyone who uses a thumb drive needs this warning needs to hear this but.........Don't try this on a drive that has the only copy of data you need...Duh.
