After months being manufactured, the Utopiums are back! I will explain more about what they are in another post, but for now here are some photos.
Here are the packaged chips (20 of).
They also send you the remaining unpackaged dies. These have an excellent ability of confusing the camera’s auto focus.
The full die is 5mm by 3mm.
And this is what they look like under a microscope. They do get dirty very quickly when exposed to a dusty room.
On the bottom right of the chip logo are the thank-yous. The Tux and the Fedora logo are about 0.5 mm tall (perhaps the smallest ever?). You can see the diffraction grating giving a nice secondary colour.
At different angles, they look very different.
And here is a wise comment left by the one of the Async symposium reviewers.
I am still testing the beast, but it does work. It has executed a number of programs and the wagging slices do become by-passable. The biggest worry was the reset as that is quite complicated, but it seems fine. I will open source the design and the tool set some time next month.
