Let's Make Robots!

Guess what it is...

Byrik

Feel free to speculate on the project I'm working on. These are zoomed in and cropped photos. What are these components and what were they made from. But most importantly: WHY!??!????

What is the purpose of this crappy switch?


Update 2 nov 2010:

Ezekiel almost cracked this 100% ! One remaining question: why?

I am Speculating that this (copper clad) switch is a form of time-ing devise to synchronise part of a process that previously had no time-ing. (the trace is pretty clean considering the "Heath Robinson" contact array).

Ie a bit like the time-ing mech in a car to fire off the sparks to the engine - however in your case it will trigger off another part of the project so that a non self-destruct occurrence will happen. (or maybe not happen )

The black and white photo confused me at first (thought it was an blade for cutting brass tubing) but i see no through hole in the plywood.

1ms pulse is quite fast - so prediction for a fast cycle. (with much noise)

Why wood :- Maybe an Asimov project looms

You are MacGyvering some points for a really old car.

Yup, bounce testing.

Why?

to test various contact debouncing methods?

Specifically to test debouncing of a switch or encoder for your TJ legged robot?

It`s a cam operated switch giving you easily repeatable experiments in contact debouncing.

It's a german thermostat dating from the days of the Nazis. What it's made out of, I don't know. Clearly a little wood, a little spring steel, some lead/tin mixture perhaps. Maybe something from the Panzer parts bin. It looks to be in really good condition considering its age...

Is the plywood part of your TJ legged robot?

I agree with UltraMagnus on the cam. I think the contacts on the right might be some sort of pressure switch. So maybe there is an analog read on that, and the position of the cam will result in different pressure and a range of analog values.

The bit on the extreme right of the bottom picture almost looks like a piece of pull chain from a light fixture.
