Archive for the “Website” CategoryHere’s a YouTube video of noted Marketing guru, Seth Godwin, talking to the staff at Google. Somehow it all seems a little weird, especially when you know that Google owns YouTube. But, in spite of that unusual twist, it is an interesting few minutes. Take a few and enjoy, if you will.
Here’s another gem from Falconphysics! Steve Dickie found another unique web tool, a “video blackboard”, well really a whiteboard, but far more than a whiteboard. Using Sketchcast as a video blackboard complete with narration one can teach, literally anything that an instructor would teach to a class using chalk and a blackboard. But this lesson can be posted to a simple web page or series of web pages and archived for future re-use. Great! In this example below, done by Steve, he provides a simple set of lessons on the physics of motion with a example of an experiment with a model rocket. Well done, again, Steve!
 
Vernier Instruments:Using vernier calipers, micrometers, and height gagesPosted by: G R Peacock in Resource, Website
Perusing our keyword searches, I was surprised to see a great many rather basic searches on MeasurementBlog for what one would consider entry-level measurements. OK. Perhaps I brought it on by reminiscing about my first serious measurements as part of a lab exercise in college. So, maybe we should put more basic stuff here to help those just getting involved in measurements. Why not? There are plenty of good resources out there in Web-land and not all are easy to find nor reviewed and organized. Here goes: Searched and found a neat little web page on using a vernier caliper and micrometer. It’s a simple set of lab exercises and looks just what a beginner should consider. It is complete with illustrations and a step-by-step approach. Kudos on a really nice and informative web page written by: Lynn Seery, Asst. Professor QET at Sinclair Community College, Dayton, OH 45402 (email: lseery [at] sinclair.edu.) To quote his Abstract: ABSTRACT

The Kepler Mission, a NASA Discovery mission, is specifically designed to survey our region of the Milky Way galaxy to detect and characterize hundreds of Earth-size and smaller planets in or near the habitable zone. The habitable zone encompasses the distances from a star where liquid water can exist on a planet’s surface. Results from this mission will allow us to place our solar system within the continuum of planetary systems in the Galaxy. Read all about the background and the planned measurement methods: at Frequently Asked Questions. The key factors used to achieve the required differential performance for the Kepler Mission are: * Differential spatial photometry: The brightness of each target star is normalized to the average of all nearby stars, providing common-mode rejection in the measuring system. * Differential temporal photometry: Transit durations are a few hours to less than about half of a day. Brightnesses are compared to data just shortly before and after the test interval, so there is no need for long term stability. * Decorrelation of image motion: Motion due to the image drifting over time scales long compared to a transit produce highly correlated amplitude variations that are removed. * Optimal weighting of pixels: The individual pixels that comprise each star image are weighted to maximize the SNR. * Keeping each star image on the same pixels for three months: Eliminates effects of inter- and intra-pixel quantum-efficiency variations. * Operating the CCDs near full well capacity: Read noise and dark current are negligible. * Selection of an Earth-trailing heliocentric orbit: Stable thermal environment and negligible scattered light background.

The online slide show (MS PowerPoint[tm]) sharing web site, slideshare.com offers a unique opportunity for geeks like us and our readers (of course) to upload the new and old files of past technical presentations and bring them to a much wider audience. I am especially thinking of slides that are shown as part of a technical paper, even a marketing and sales presentation, that makes one or more interesting technical points, describes an experiment and its results, describes a new technical improvement and so on. An interesting web technology with several possibilities! You might post the slide show to a webpage with other, related ones, even from a seperate conference, to put it more in context or even create a virtual meeting with many slide presentations. Anyhow, here’s an example that I am trying as an experiment in this post: a slideshow on RFID technology. Appreciate any feedback, especially from the ThermoSense community, one that has a large reserve of underused PowerPoint presentations spread across the world and each usually seen only once and then by a very limited audience.
Some of the visitors may recognize that I a write a newsletter and occasional articles for Sensorsmag.com, formerly the website for Sensors Magazine. The magazine stopped publication of the paper version at the end of 2006; it’s all online now. The website, Sensorsmag.com and the Expos sponsored by them, continue, bigger and better than ever! So, too, I believe, are the resources they bring to measurements. They have a searchable online database of technical articles that is rich in useful information about sensors uses and a whole lot more. OK, some of the articles were not the best, being thinly disguised marketing prose from equipment suppliers, but even among these, non-peer reviewed stories, are some gems of technical information. We picked some of them and have been posting links and descriptions about them in the database at our site, TempSensor.net, along with similar listings for other online resource articles. (at last count we had reviewed and posted nearly 150 articles!) The articles are organized by sensor type; just click over there and find out more than you ever wanted to know about temperature sensor details. We are doing the same at Measurement Databases, but the going is a lot slower. That’s because there are so many stories scattered around the Web and it been mostly a solo effort until now. We encourage visitors to visit and suggest links, especially to the “tech gems” such as article reprints, white papers, online courses and tutorials about measurement and measurement devices that dwell in the depths of corporate and other websites. They seldom see the light of day (or a listing in a search engine); we’re changing the situation by shining a new spotlight on them As I see it, it is a true win-win-win situation: The organization or even an individual wins because their documented technical expertise gets broader coverage being listed in our resource databases, and… each new listing is featured as a title and working hyperlink on the front pages of our sites for a day or more. That, in turn, gets picked up by the dozens of spiders and web robots that search our sites daily! More links to their websites and more visibility for their technical expertise. Prospective and existing customers win because they can more easily find the information they seek. It’s referenced in more places on the Web and our website traffic continues to grow improving our rankings as some of the best technology resources for measurement on the Web. (About Temperature Sensors and TempSensor.net already have first page placement on many search engines!) We win since we grow our strong technology links wider and deeper. So, far we have not seen any search engine that can deliver better resource information than human-reviewed ones, like ours! When we grow, we earn more from our advertisers and can afford to continue to grow even more. So, again, I thank SensorsMag.com for a great web resource for anyone involved in measurement. You can search their article and news databases to see for yourselves. It’s enabled us build a measurement resource or two. We have already done it for Temperatures Sensors and have posted links to the real gems from Sensors’ and other websites on our site. We are doing it for other measurement devices at Measurement Databases and MeasurementMedia.com. (The latter website focuses on resources related to Publication, Standards, Meetings and Education related to measurement and measurement devices) I could use your input, too!

OK. I’ve been quiet enough. (Well, I’ve been busy building a measurement website “mini-empire”, see any of the links to them. That has kept me a little busy- but we did it-I had help- for two reasons: to build searchable databases and to pay for the structure - ads, mostly from Google, do that.) The goal is to organized the useful, informative & free resources on the Web into commented, searchable information on measuring. Oh, yes, and we want it available to all, free, no cost. My reason for making websites was to provide communications from more than just me; communications about measurement devices and their selection, calibration and use in industry & science. Our sites are evidently reaching a good number of students and some professionals, but that’s not enough! Hey, I don’t know it all, but I know enough to help some people stay out of trouble in a few areas. Some of you do, too, in the same areas and others as well. The fact is, about 99% of visitors to our sites really seek help in understanding how to “measure”. We can use your help. Just write or submit links, articles, anything but spam. (We delete all the spam we can find.) So, there’s a big need, not just how to find a vendor, that’s way down the list of steps in measuring but to learn how to take all the steps and to select a vendor with the proper care. There is also a need to help people, especially engineers and scientists, do a better job in measurements of all kinds. I’ll relate some of my experiences later in other posts. Meanwhile, I encourage those who do know about measuring and measurement devices to use our sites to post your favorite links, tutorials and comments on helpful online resources. Comment here, if necessary. You can do it anonymously or get credit. You can even help by submitting your own articles to share with the rest of mankind, who really needs the help. If you write well and want to participate as a regular author or editor, let me know. Our temperature sensor websites are pretty well in-depth and are good models of where we’d like to go with our other sites. Measurement Devices sites are still in growth mode; it’s a huge scope with copious free, online resource info and tons of chaff to get sorted to find the wheat. Results like ours won’t appear on Google, Yahoo or MSN any time soon because of their special problems with “chaff”. Same with Wikipedia, its content is too spotty, limited and often variable. And DMOZ is just too general , without commentary. TEMPERATURES.COM, INC. publishes information about measurement devices and measurement on its websites.
