So Mike is going to visit the Pleasure Dome (Max's Office)... I would love to spy you through a little hole, I'm sure this is going to be a delightful meeting with one of the greatest APP's old school bloggers.
I can remember how the Mighty Hamster built a high-speed serial interface between two low-end Spartan FPGAs by just using a hand-made twisted copper pair and delay blocks implemented with conventional LUTs and CLBs. I remember he was able to reach some hundreds of Megabits per second, a really impressive work!
I certainly remember and am grateful for all the good advice I got from the Mighty Hamster back when I was a FPGA fledgling on All Programmable Planet.
I didn't realize that Max land is so close to Rocket Land. The two places would certainly make for a rousing visit to the USA. Nor, did I realize that the space center there has a genuine Saturn V rocket. I've seen the one at the Kennedy Space Center, in Florida, and it's impressive.
@Duane: "I certainly remember and am grateful for all the good advice I got from the Mighty Hamster back when I was a FPGA fledgling on All Programmable Planet."
APP was a real cool place to learn new tricks and skills for the FPGA developer. I remember that you started writing about FPGAs from the ground-up and, soon after, you were teaching us how to wire & control COTS modules to an FPGA by using standard serial interfaces (I would highlight your I2C blog series). A very impressive progress!!
I can't believe you didn't mention, Max, that since the Papilio Duo meet its second stretch goal, the Hamster will be updating his tutorial for it. Since I backed it and one day would like to play with HDLs, I'm pretty excited about that.

On the subjects at hand (Morse, Hacking, and Wireless), it seems that systems were being hacked long before Captain Crunch and his ilk, back in the early days of what became electronics.
The Maskelynes were three generations of magicians, starting with John Neville Maskelyne in Victorian England. I ran across this link to a New Scientest article in a Wikipedia article about Neville Maskelyne, son of John Neville and father of Jasper:
It seems that Neville was a bit peeved at Guglielmo Marconi for many reasons, not the least for his claim that wireless telegraphy was secure, and, like Anonymous and other modern-day hactivists, hacked Marconi's Morse wireless demonstration to the Royal Institution in 1903 to embarrass Marconi and prove him wrong.
Thank you for sharing that. There's also a great "wireless telegraphy" hacking scene in The Count of Monte Cristo (1844). Telegraphy in the book predates electric telegraphy and uses a line of telegraph towers -- each visible to its neighbors -- to relay messages manually across long distances. The hero spoofs a message from Spain, which causes his enemy to make a financial bet that ruins him when the actual facts arrive.
Dare I ask about the placement of this tattoo? (Inquiring minds want to know)
And I'm writing this in jealousness of the amount of genius that will exist in one place in the space time continuum. (Have you checked with the authorities on the maximum amount of geniusness allowed in any given area (gs/m2)? You may be pushing the envelope of or universe in what you're trying to do.)

It's funny you should ask that -- only last week I had the shielding checked in my office.
Have you read Blood Music by Greg Bear? This also touchs on this theme. Now, that's one book I would recommend to anyone -- an extremely good read. In fact, now you've brought it to my mind, I think I'll read it again.
I just had a [most likely silly] thought.. How do you quote "SOS" in morse? Like "SOS is an international distress signal" without drawing rescue attention? Since I was born late enough to grow up during the digital age, I learned the ASCII table instead of morse code, but I can pick up the "SOS", but not the rest.

I don't think it woul dbe a problm because the listener would hear it in the context of the rest of the message. Like if you were at a play and one of the characters on stage said "I smell smoke, I think the building ios on fire," I doubt that the audience would immediately leap up and run out :-)
Or you could just space them sufficiently that it's obviously not one word. so you would send "S O S" instead of "SOS". Incidentially, I've heard that if you are really sending it as a distress signals you're supposed to run it all together as of it's one character instead of sending as three separate characters.
What can I say but the Pleasure Dome is everything that was promised, and I will never forget the unfriendly face which welcomed me - I'm going to have nightmares about people climbing out of random holes in the floor. And thank for letting me see all the wonders you have collected (esp. the Enigma machine).
The US Space and Rocket Center was awesome. Just to think that the mighty Saturn V can get off the ground is awe-inspiring. I love the cut-aways of turbo pumps that can move fluid almost as quick as an Aussie in a pub, I also enjoyed hiding from the rain under a Space Shuttle, taking to the guy who helped design the lunar rover (did you know that the wheels are hand woven piano wiere, and based on an a UK patent form the 1800's?), looking at the Saturn Launch Vehicle Digital Computer through a magnifying glass, seeing two ST-124-M3 inertial platforms - I want one!, standing by the Lockheed A-12, and checking out the Apollo 16 capsule's heat shield....
I also found out that if the don't fill some of the rockets on display with compressed air they would crumple. One has a small compressor sitting behind it just for topping it up every now and then!
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
