Excellent Dave, FPGA.

I have a DEO Nano as well as a DE0. Looking forward to try it out as well as looking forward to any future video on FPGA and even Micro's

I love how symmetrically shrunken the quarter is - the text and image aren't distorted at all! It's impressive that you can shrink something like that to two thirds its diameter in microseconds and do it so perfectly.

For the geiger counter try  with a clock with luminescent background, the one that you can see in the dark.

You probably have to lift the skirt off of the smoke detector to get a signal. It's just an alpha source, and probably covered with a metal can to keep the radiation out. Please weigh the quarters. My prediction would be that the compressed one is slightly heavier due to oxidation on the surface. And FPGA videos, yes please!
Whoa! How the hell did Dave know that Bob is my uncle? Amazing!

Yes, please do some FPGA videos. I have just experience with microcontrollers yet and think reconfigurable logic is an interesting topic to learn something about.

Well, that made a decent dent in your mountain of mail.

But still a bit disappointed by this mailbag. A lot of (nice) postcard but only 2 nice items

Can two randomly selected, clean quarters be expected to have such similar mass that a bit of oxidation will make a measurable difference beyond the existing difference between them?

I definitely want to see FPGA segments using the DE0-Nano, please.  I've always wanted to know more about FPGAs.

The Timberline Lodge you looked at in the Oregon calendar was used in the classic Stanley Kubrick film, "The Shining" which was a rare example of a movie that was far better than the novel it was based upon, thanks to Kubrick's great talent, of course.  From Wikipedia:

"The 1980 movie The Shining used aerial shots of the Timberline Lodge as part of its opening scene, and exterior footage for some establishing shots of the fictional Overlook Hotel throughout the movie. The movie was based on the Stephen King novel of the same name, which was inspired by The Stanley Hotel in Colorado.[citation needed] Several of the exterior shots in the film which purport to show the lodge, such as those of the hedge maze and loading dock, were taken at Elstree Studios in England, using a mock-up of the south face of the lodge. There is no hedge maze (and hardly any level ground) at the Timberline Lodge. All interior scenes were shot at Elstree Studios as well, and do not depict the interior of the Timberline Lodge."

Another vote for showing us the FPGA demo! It's a new area for me.
You can do anything with the right attitude and a hammer.

If I knew, I wouldn't be asking. Then again, the question is if Dave has a precise enough scale.

That's probably about as likely as a chemist having a 6.5 digit multimeter.
