OK just for a bit of an off topic excursion 
It's an optical collimator bench for the modern day theodolites ( UTS /TS = Universal Total Station / Total Station
or as affectionately known by surveyors as "jiggers")
here's a side on pic ...
the collimator telescope is on the left and has an illuminated crosshairs target and digital camera down at the left end
The total station (TS) unit is to the right and in this pic is facing away from the telescope
The TS's are supposed to be stripped down, cleaned and calibrated yearly ( if the owner is good)
Once I have stripped down and relub'ed bearings and cleaned etc, I then have to realign the optics in the TS and check the EDM
( Electronic Distance Measuring ) accuracy and do adjustments to correct any errors. The unit above is a high accuracy unit, accurate to
1mm +- 2mm and 1 sec of arc +- 2 sec at 300 metres. The high precision units are 1mm/1 sec +- 1mm/1sec @300 metres
They range in price from ~ AU$40,000 to $55,000 depending on the model and precision.
These units are made in your home country by a company that Trimble acquired.They are used for general surveying and for machine control
the one below is set up for machine control -- it is optically and radio linked to the machine in the background

I photographed a sunset today, and I also took a shady selfie. Just for this PF thread, I very seldom take selfies

Red rose? Mine is a red _nose_ ( face paint, etc.) ;).Aufbauwerk 2045 said:I would like to post my photo. First I need to get a new webcam. Then some candles so there will be some light in the room. Also a Guy Fawkes mask. Finally a red rose, since that's my avatar.
Or I could just post a photo of someone who looks a lot like me. Although I would not do it for legal or just politeness reasons. I was amazed to find an apparent doppelgänger in a very surprising context. Creepy. Has anyone else come across a doppelgänger online? Would posting my doppelgänger be an example of "fair use?"

I had no idea how impressive the Tichy family actually are... .fresh_42 said:I prefer to travel with Ijon Tichy.

Jeremiasz Tichy, Ijon's grandfather, created the General Theory of Everything, and nothing stopped him from doing so... .

Best I know is the "Tiki" family from https://en.wikipedia.org/wiki/Thor_Heyerdahl . Not the same, but a really cool first name:
Thor. No need for a whole family when your first name is Thor.

So, I lost all my documents and to get new ones I had to take a picture of myself. I doubt this one will be accepted by authorities, but I admit I had plenty of fun![]()
Are you related to Robert Oppenheimer ?

School photo. How boring. Half a year ago. :)
Unfortunately I do not look much like a nerd, but everyone in the class hates me and my friend, because we are 'nerds' and always beat them in all the tests
