This is the innards of my TI SR-50. It demonstrates how far we've come in 36 years of electronic evolution. Today's circuit boards have very few "discrete components" on them, and the ones that are mounted to the board are much much smaller than these gigantic dinosaur bones. If you've ever fiddled with hobbyist electronics, you know what you're looking at here... resistors, capacitors, transistors, inductors, a PC board, a couple of Integrated Circuit packages... it was quite sophisticated for the time, but the computer that runs your car now has thousands of times more computational power than this thing does... and those computers are idiots compared to an off-the-shelf PC you would get at Best Buy. But it was super-advanced for the time. It would have been plenty enough to get the Apollo 13 astronauts home safely. As was, sliderules did the job, but not without some worry that maybe an engineer had positioned his slide incorrectly, each time he'd done the calculation, and this the quintuple-check was still wrong and the capsule would hit the atmosphere too steeply and having returned all the way from the moon, burned up 50 miles from safety. Oh for one of these calculators just a few years earlier. But oh well, the astronauts got home alright anyway, and we went on to create ever more powerful computing machines, only to have one of our Mars landers make it all the way to the Red planet just to burn up in the atmosphere because some programmer somewhere had thought the number he was working on was in feet, and it was entered in meters. Fortunately, that lander didn't have people aboard.
Well, that's enough of a ramble on the guts of my old calculator. I think boards like this, where the components are just sitting there, plain for all to see, are beautiful things. The new boards, motherboards for our modern computers and such, are marvels of electrical engineering, but they're not colorful, not engaging, not nitty-gritty sexy like these were. We'll not see them again, but they were, in their time, the very best we could do.

How do the images picked up by the spinning head get to the rest of the cameras electronics. By radiowaves transmitted a VERY short distance from these circular "aerials". Similar "aerials on the "fixed" part of the cameras electronics. Pretty nifty eh!
The power unit of ex-English Welsh & Scottish Railway/DB Schenker class 37/4 No.37422 was extracted at Direct Rail Services Ltd Kingmoor Depot, Carlisle today, 4th June 2012, by a heavy lift crane brought in for the purpose. Beyond the depot security palisade fencing viewed from the Kingmoor Sidings Nature Reserve, the power unit is seen on a road trailer ready for transportaton away from the depot as the shell of 37422, with its roof panel removed, stands alongside. It remains to be seen what will happen to this locomotive, but this may be a positive indication.

Exercise Dynamic Mariner tests NATO’s Response Force Maritime Component (NRF/M) and interoperability with NATO forces, enhancing flexibility and improving the ability to work together among Allied nations. It runs between 28 September and 8 October 2020.
The exercise brings together 31 surface ships, 1 submarine, 3 maritime patrol aircraft and other air assets as well as personnel, from Belgium, France, Greece, Italy, Netherlands, Spain, and the United States.
DYMR20 is led by the NATO Maritime Command and involves Standing NATO Maritime Group Two (SNMG2) and Standing NATO Mine Countermeasures Group Two (SNMCMG2), two of NATO’s Standing Forces on active duty that contribute to the Alliance’s collective defence on a permanent basis.
HNMLS De Witt and HNMLS Rotterdam conduct amphibious assaultin Cassis. Dutch Mariners in assault.

Ingredient for a simple target board: Perfboard, 6-pin DIP header, optional battery box, and two types of 20-pin socket: low cost and zero insertion force.
Photo taken to accompany short article on working with AVR microcontrollers, and making minimalist target boards for programming them.
it's a bit like building a model sailship, but you have to see beyond the surface... let's face it, sailships are prettier.
However, this will do sound, which is cooler :)

As part of the team building component of Term 1 Project Management, first term students are each given a box of dollar store objects and a mission: keep a marble moving along a course for as long a time as possible, with it ending up falling into an egg cup. Armed with plastic necklaces, dominoes, bendy straws, a roll of toilet tissue and other priceless objects, teams compete to create the best design to meet the goal. Upon completion, the teams analyzed their design for its strengths and weaknesses and the teams process key team dynamic components — How were design decisions made? How were disagreements resolved? How was leadership determined? Did team members contribute equally to the vision and how did they each fare when it came to implementation?

The gear is shown with a spacer already press fit into the 1/4" central opening. I would have liked to photograph all the components separately but I couldn't easily separate these pieces!

Viewfinder removed from an old film camera. _Really_ interesting mechanics - it's like a periscope with more magic.

Budget CPU more for heat dissipation reasons (low heat = low cooling noise).
Not a Intel chip despiteeveryone and their mum saying AMD are left for dead atm; It's moralistic buying.
What would you call this one? Tribal? I'm having trouble describing this pattern.
