My Rolleiflex stopped working - the mirror had locked up and it was all jammed - thankfully someone knew who to call, and guided me through taking off the side panel, and pulling a release lever that brought the mirror back down. This camera used to be very much the in thing in the 1960s - it features an all mechanical mechanism, with discrete shutter speeds from "Bulb" through to 1000th/s - this bunch of mechanics deals with shutter release, timing, mirror flip and film winding - amazing piece of kit.
To transform from Paralyzer to Eliminator mode, two panels on the side are first released. Then the gun is tilted upwards and the trigger is slowly pulled.
To transform back from Eliminator to Paralyzer mode, the side panels are first lifted. Then the gun is tilted slightly downwards and the trigger is pulled quickly. The side panels are pushed back into place.
Sorry for the low quality... I don't have a video recorder as of right now.

After years of use, truck tailgates need a little attention. When you don't have the proper rod guide pieces, ty-wraps work in a pinch. And, of course, the tailgate opening mechanism will fail when you have 100 lbs. of something you need to put in the back of the truck and can't open the gate.

I took my newest camera, the Hasselblad SWC, to the steam show this year.

When we first decided to go to Greece, there were two things on my must-see list: the Acropolis and this thing. It is an ancient computer of fantastic complexity and the only object of its kind that has been discovered. Seen here are fragment A (center, 180 mm across), which is from the back of the mechanism and contains most of its gears; B (left), which shows about a third of the Metonic (lunar calendar) spiral from the back dial face; and C (right), containing a portion of the front dial face (zodiac) and the indicator for the position and phase of the moon.
The mechanism, dating to the second or early first century BCE, was found by sponge divers in 1901 in a shipwreck off the island of Antikythera (which sits opposite the island of Kythera) and has been gradually decoded over the decades. From the outside it reveals only corroded lumps of bronze with enticing hints of gears and wheels. But X-rays and CT scans starting in the 1970s -- the object was too fragile and valuable to travel, so scientists assembled a room-sized early CT scanner in the museum -- have enabled people to accurately count gear teeth (crucial to decoding function) and even read fine-print inscriptions.
On the front was a large dial indicating the positions of the sun, moon and planets and phases of the moon. It used an eccentric mechanism to accurately model the motion of the moon, which speeds up and slows down as it travels its elliptical orbit; showed the phase of the moon with a half-black, half-white rotating marble; and is believed to have used epicycles (extra gears) to model the irregular motion of the planets. This device's forerunner the planetarium of Archimedes was said to have had similar capabilities.
On the back, the top main dial was a 19-year (Metonic) lunar calendar. The right inset dial told when the Panhellenic athletic games (Olympian, Nemean, Isthmian, and Pythian, as well as 2 minor games) were due to take place. The left inset told where one was in the 76-year Callippic cycle (i.e., which of the four turns of the 19-year Metonic cycle one was on).
The bottom main dial indicated the dates of future solar and lunar eclipses, with time of day and other details. The dial covers an ~18-year period (the Saros cycle); however, the actual repeat cycle takes three times that. The inset dial, divided into 3 sectors, tells where one is in this ~54-year (exeligmos) cycle and thus whether one needs to add 0, 8 or 16 hours to the predicted time of day.
A shout out to the Clickspring YouTube channel, which documents a step-by-step re-creation of the mechanism -- using only tools and materials that would have been available at the time.

Would you guess what this is?
It is an impressive lock mechanism (from the 16th century) of a big
metal box I found in the Citadel of Dinant, Belgium. I really love the
shapes, textures and symbols... I took this photo last summer and
forgot to share it (I made some edits to improve the details, colors,
composition...). View some of my other photos taken in Belgium.

A view of the mechanism inside my latest walker.
Of course, I used a system frame, not a Technic one. Adding pairs of legs is pretty simple, and using 6 legs will produce a more fluid movement!
This mechanism only allows the walker to go in a straight line. If you want it to turn, you'll have to power each side by its own motor.
LDD file can be downloaded on my website.
upon re investigating this title, i realized it was hilarious, and ironically true in part. A month later. ∆
Professor Michael Edmunds of Cardiff University who led the study of the mechanism said:
This device is just extraordinary, the only thing of its kind. The design is beautiful, the astronomy is exactly right. The way the mechanics are designed just makes your jaw drop. Whoever has done this has done it extremely carefully. In terms of historic and scarcity value, I have to regard this mechanism as being more valuable than the Mona Lisa.
'Sup guys. Here's the door mechanism, I hope it conveys the basic idea. Let me know if you have more questions.
I tried to keep it simple as possible, and seeing as the interior of the bullshark is basically all black, I removed it so you could actually see what's happening.
My project is fun, there are lots of details to discover!

Here's a reminder of what the Daily Mirror thought back in 2015. Five more damned years was a miserable prospect, yet somehow the buggers survived two further general elections and are still in power. Opinion polls suggest that they'll lose the election this year, but it would be foolish to underestimate the Tories' desperation for power or their ability to persuade people to vote for them.
