Compute

Computer issues stopped me posting anything yesterday - a shame as I use lots of non camera lenses (I adapt all sorts to my cameras) such as this rear projection TV lens
flic.kr/p/2obXFiF which works out roughly 150mm/1.2 and covers 5x4 comfortably.

Then there's crystal balls flic.kr/p/2m3ezUG flic.kr/p/2kjhN19

Fresnels flic.kr/p/2m3d1Fo

& microscope lenses flic.kr/p/2aSzfax

Finding something suitable for todays theme is more tricky...

I guess this board from an old mass spectrometer did calculations of some sort

When I re worded yesterday's theme I was thinking that you would have some good examples. IIRC today's was also one of dorsetmike 's though the original asked for computer accessories.

My son's 'gaming' chair.

Compute

Short of showing the results of some calculations on the computer screen a calculator is all that I can come up with. I don't think they make them anymore, probably the victim of their longevity - this one says 1987 on the back.  Has seen a lot of use.

Ok guys and girls, looks like I have come up with a difficult one today. Perhaps think small machines, coffee machine, sewing machine, vibrating tension relief machine.

1927 Magdeburg lathe in use up until about six years ago.

A small SouthBend Lathe I owned years ago.

[dorsetmike]

A smaller lath with milling attachment I still own.

A plotter cutter, same principle as a plotter for drawing but pen replaced by a blade, cuts card, vinyl, and other plastics; larger versions often used to cut lettering from self adhesive plastic for vehicles. Smaller ones like mine mainly used for cutting card or plastic sheet for models. Detail to be cut is "drawn" on a computer which then drives the machine.
