In this strange pandemic time, SC20 has gone virtual -- which makes our 27th SC research exhibit a bit awkward. We do still have a WWW page, http://aggregate.org/EXHIBITS/SC20/ , and Professor Hank Dietz will be available to chat via a Zoom link that will be posted on that page during times when he's available.

The Aggregate SC2020 Research Exhibit This is the home page for our 27th major research exhibit at the IEEE/ACM Supercomputing conference... which is not really a thing this year. Yes, University of Kentucky / Aggregate.Org officially is participating, but it's all virtual and not very interactive.

Well, our SC19 exhibit is coming to a close... here's what you missed.

We'll again have a research exhibit November 18-21, 2019 at https://sc19.supercomputing.org/ ... come see what we've been doing, including the completely operational version of what you see below....

Just created ShAKY (Shift Angle KentuckY) sensor module to monitor 9-axis motion of a Canon PowerShot. We created it for a variety of research experiments involving new methods to obtain better images in the presence of camera shake. It's on Thingiverse at https://www.thingiverse.com/thing:3665981

Once upon a time, in a lab not far from mine, there lived an evil old Stratasys 3D printer. It's not there any more. After all, I did say it was evil, didn't I? However, when it was discarded some years ago, I got a couple of big boxes of filament that were bought for it. Some was white ABS, but most is the P400 Soluble Support material... brand new from 2012. The Material Safety Data Sheet is https://store.stratasys.com/medias/?context=bWFzdGVyfHBkZnRhZ3N8MzQxNDQ3fGFwcGxpY2F0aW9uL3BkZnxwZGZ0YWdzL2hmZC9oMTYvODg5MDI0OTI0ODc5OC5wZGZ8MTZhOTBmNTk5MGRjYmEyNzFkZWZhMDBmODRmYTI3MWJjNDJiMmIwYzFiZmE0NjIwZjhjZTUyMmQ4YThiMWRjNQ

So, we tried printing with it on our ANYCUBIC hoping it might be a good filament to do test-fit prints, etc. -- which it seems nobody else has done. It prints very crisply at 230C on a heated piece of blue painters tape. It is essentially like an acrylic, with the resulting parts quite stiff, and they either suffer layer separation or shatter when they break. They don't dissolve, nor even soften, in boiling water, but the material turns from dark brown to gray after exposure to hot water.

Anyway, since nobody else seems to have done much with this filament (one spool of which costs more new than the ANYCUBIC printer we used), I figured I'd report our findings here.

We've just added another 3D printer to the lab: an ANYCUBIC Linear Plus (middle, between MakerGear M2 and Wanhao i3). Really an excellent printer; slow, but very nice and very cheap.

EDay open house is Saturday morning at the University of Kentucky. Our Marksbury lab will not be open, but we'll be showing-off a quantum computer and other goodies in 581 FPAT....

Well, we're off to SC18 with our fully operational 6-qubit KREQC... and some qubit keychain/fidget spinners. See you at SC18 in the University of Kentucky / Aggregate.Org exhibit! In case you hadn't guessed, the big thing we're talking about this year has to do with quantum computers....

Getting ready for SC18.... Meet KREQC (pronounced "creek"): Kentucky's Rotationally Emulated Quantum Computer... or at least it's first fully operational Qubit. :-)

A variety of things cooking this Summer. For example, just got a Walabot to play with RF imaging.... More soon.
