Pragmatic Metrology is a site where people of all skill levels can learn more about Inspection and Metrology using the industry's most-common hand tools, surface plate tools, and key concepts.This free series of videos and resources is designed to let students to learn from home or work, following along with their own equipment. There are instructional lectures, hands-on demonstrations, and key point reviews.
This side project is intended to hopefully provide more online resources for learning about inspection and metrology and close the manufacturing skill gap.
Most of this content can be found online at other sources, but when its so spread out and not consistent, it makes learning challenging. I wanted to provide one consistent style and method but I encourage you to look at additional resources. Getting other perspectives will help you understand the more challenging subjects.
It's not a substitute for a hands-on instructor lead course you might find at a community college like Laney in Oakland, CA. However, for those who cannot attend classes, I hope you find the information here helpful to your inspection careers.
At this time, all content is uploaded and available. I'm not planning to put too much more effort into new videos or content. But there's already 28 hours of training videos (56 if you count both cameras), helpful resources, and practice exercises with drawings.
As I said, I encourage you to look at more sources of information. Websites, books, other videos, instructors, coworkers, colleagues, etc. Occasionally, while you're watching these videos, you'll see something you don't agree with (hopefully not a lot). Could be a mistake on my part. Could be the explanation is not good enough. I've tried my best but I know there's always room for improvement. Ask other's your concerns. If there's anything drastically, just flat out wrong, I'll try to address it. Mistakes happen. Understanding can change and evolve. The key to is keep learning and growing.
If you're interested, you can learn more about the Instructor's background here.
Video Quality and Distribution.
For now, all 28 hours of videos are uploaded for free on Youtube.
You may notice there are some problems with these videos:
- Audio is not synced
- An unfortunate consequence of the equipment I used. I do not have the time or resources to fix it. I do apologize and hope that one day I can fix the sync issues, but its going to be a big project.
- As a workaround, I suggest watching both angles on two devices or two browser windows. Play the video from the main angle, but the audio from the top angle.
- Audio quality is not good on some videos
- I know quality varies as well. Again, live and learn. I believe about 2/3 of the videos were made with a better microphone than I originally started with.
- Video quality is poor
- Part of this was due to the cameras auto-focus feature just not working.
- For the main camera view, sometimes there is too much glare off the TV screen while I'm demonstrating the tools. Try switching to the video feed from the top view.
- Part of the problem is Youtube's video compression processing. Made the video quality a little worse than the original files. An unfortunate consequence of online streaming.
- If the quality does not look good, try verifying you're getting the 1080 or 720 stream from youtube by checking the video player settings.
Your support is appreciated.
