Discussion Overview

The thread centers around a photo contest where participants are invited to submit images of measuring devices. The scope includes various types of devices, ranging from simple tools like rulers to complex instruments such as electron analyzers and detectors used in high-energy physics experiments.

Discussion Character

  • Contest-related
  • Exploratory

Main Points Raised

  • Participants are encouraged to submit photos of measuring devices, with a requirement to describe unusual devices.
  • One participant mentions an electronic tuner as their chosen device.
  • Another participant shares a photo of the ATLAS detector during maintenance, noting its unusual status as a measuring device.
  • A frequency meter is submitted, with specific details about its specifications.
  • One participant discusses a vintage NTSC vectorscope, expressing doubts about converting it to a standard scope.
  • A participant shares a photo of a caliper, which is questioned by another participant regarding its classification as a precision scribe.
  • A pycnometer is presented as a highly accurate measuring tool used in a lab setting.
  • A Kelvin probe is described, detailing its function in measuring contact potential difference.
  • Participants express admiration for each other's devices, highlighting the variety of measuring instruments shared.

Areas of Agreement / Disagreement

There is no consensus on the classification of certain devices, such as the caliper versus precision scribe, indicating some disagreement. Overall, participants share a variety of measuring devices without a clear resolution on any specific point.

Contextual Notes

Participants are reminded of the contest rules, including submission limits and photo requirements, which may influence the types of devices shared.

A Measuring Device

Pictures this week must have, as the main subject, a measuring device. This can be as simple as a ruler, a weight scale, a speedometer, all the way to an electron analyzer and the ATLAS detector at the LHC. Any device that actually gives you a quantitative value of something is a valid device.

To prevent me from chasing you and asking you to clarify the device in your photo, please include a brief description of it if it is an unusual device.

Contest Rules:

1. Any digital photo or digitally-scanned photo relevant to the theme will be accepted within the contest period. In case there's a gray area, or you're not sure if the picture is suitable, check with me first.

2. Please resize your digital photo to no more than 800 x 600 or 600 x 800 pixels. You may also crop your picture if you wish. You are also allowed to adjust the brightness and contrast of your picture but these should not dramatically alter the look of the picture. But other than those, any form of picture editing or modification is not allowed. This is a photo contest, not a picture editing/special effect contest. You may add a watermark or your name/nickname to the photo for identification purposes.

3. Upload your photos to any of the photo servers such as imageshack or photobucket. Then post it the relevant contest thread and link your picture using the img command. PM me if you do not know how.

4. Only ONE picture per member per contest. Once a picture is posted, it cannot be changed other than a total withdrawl by that member from that week's photo contest. Exceptions will be made for modification to comply with the rules, such as resizing.

5. At the end of the contest period, I will open a poll and every PF member can vote for the picture they like best.

6. Note that in case we have a large number of entries, I will do the polling in more than one thread. If that's the case, you can vote in each of the polling threads. The photos will be assigned in the polling threads in the order they were submitted.

7. The photo of the subject must be something that you took directly, not via in intermediary medium, and not taken by someone else. Unless otherwise noted, a photo of another photo, painting, print, etc. does not qualify.

8. You can use a picture only once. Once it is used in a contest, it cannot be reused in another contest.

9. Please post only pictures meant for submission in this thread. Photos not meant for submission must not be posted in the contest thread. Posting of more than one photos by a member may result in an automatic disqualification from the week's contest.

(An electronic tuner)
 
I think it is an unusual device, but it's in your list ;).

ATLAS during the long shutdown 2013-2014, partially opened for maintenance.

Here's mine.. I was hoping to be able to convert it from an NTSC vectorscope to a standard scope, but I don't think that'll happen.. Oh well, it was cheap.. Circa 1964 I think?

Isn't that more of a precision scribe than an caliper? My Mitutoyo calipers just packed it in after 10 years (and I got them used)... I used them as scribes a whole lot

A pycnometer, one of the most precise tools in my lab, capable of 6.5 digits of accuracy:

A Kelvin probe. It measures the contact potential difference between the tip and the sample. If you know the work function of the tip, then you directly measure the work function of the sample.
