I tell you, there are so many interesting "happenings" and "nuggets of news" and "tidbits of trivia" bouncing around the Internet that I can barely keep up. Over the course of the last couple of days, for example, I've seen so much "stuff" that my head is spinning like a top. For example...
My chum Wilfried in the Netherlands writes:
- Space Shuttles For Sale: As reported in PhysOrg.com, NASA is going to sell off its old Space Shuttles. Now, at $42 million I'm going to have to really start saving, but the good news is that this price already includes the $6 million shipping-and-handling charge. Hmmm, on the other hand they don't say anything about sales tax...
And then we have my friend Bob Paddock, who is constantly regaling me with tempting tasty tidbits, such as:
- Missing Memristor: Here's an interesting article from IEEE Spectrum titled How We Found the Missing Memristor. As you may recall, a memristor is a new fundamental circuit element that joins inductors, capacitors, and resistors.
Of particular interest to the readers of Programmable Logic Design is the note on page 6 of this article, where the author notes that he's published another paper showing that memristors could vastly improve FPGAs, shrinking them by nearly a factor of 10 in area and improving them in terms of speed relative to power-consumption performance.
- Space Computers: Here's an interesting piece from the NASA TechBrief's site discussing the replication of the functionality of the onboard space-shuttle general-purpose computers (GPCs) in field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs).
- Saving Forests: In this jolly interesting article titled Can we save forests by listening to the trees?, researchers describe how trees that are stresses emit sounds pitched too high for human hearing.
Bob notes that this might make an interesting project for someone armed with an FPGA... you could use some 4066 or 4053 transmission gates as a balanced mixer and an FPGA to generate a tunable carrier frequency for a down-converter from ultrasonic to human hearing range (Search for "Knowles Acoustics" on DigiKey: SENSOR ULTRASONIC 10K-65KHZ SMD).
Meanwhile, our old friend Jay Dowling is constantly rooting out interesting sites with which to tease and tempt me, such as:
And the list goes on... I was originally planning on posting separate (more detailed) blogs on each of the above items, but by the time I'd finished I would have another pile the same size. I'm too young for all of this...
