Things I Learned: Video and Image USB Transfer Rates

 Using my camera as a camera and my computer as a computer just works better.

The video files from POTA and SOTA outings on the new camera weigh in on the order of GBs of data. That makes for some pretty great videos, but also for slowish transfer speeds, especially from the camera's USB port out to the desktop computer at home. The camera, a Panasonic Lumic DC G100D was clocking 15 MB/s downloading data to the computer. Switching to a Thunderbolt USB-C cable moved things to 16 MB/s. When I tried to move video files from the computer back into the camera's SD card, that data rate was even slower at aout 5 MB/s.

Fortunately, 12 year-old Mota, (internet alias), got a GameBoy knockoff for his sib for Christmas. The little gadgete uses a micro-SD card, and so yesterday Tawnse asked if we could get an SD reader so we could  move games on and off the machine. I ordered one. This morning, when I tried to use the SD port on said reader to move files from the camera's SD card, they went at a much faster 83 MB/s! 


As usual, integrating the kids' interests and mine is working out great :)

Update:

The point of moving the videos to another computer was that that computer was on the better WiFi network. Once I had the card reader on that computer, I tried another experiment. I tried to move a video directly from the card to Google Photos. The estimated time, once things setttled, for the transfer was 22  minutes. When I instead moved the file off the card, onto the computer, and then to Google Photos, the card to computer transfer took about two minutes, and the internet transfer rate went down to 20 minutes, so not worth the effort for one file at a time at any rate.

It also looks like moving files to Google Drive is faster than moving files to Google Photos. The settled estimate for the same size of transfer at 4:49 was 16 mintues. That transfer is directly from the SD card to the internet. I'll keep you posted on how reliable that number is.

The Chromebook I'm using only has one USB C port that brings in power, and at the moment is also reading the SD card. The computer slept and dropped the transfer since it wasn't on wall power. Trying again at 5:04, 18 - 19 minutes left at 5:05.  Sigh... 18 - 19 minutes at 5:46. Still having issues with measuring, but at 6:19 the estimate for a 3.8 GB file is about 11 minutes. Strike that, 17 minutes. 

Grrr setting time. 7:07 and 20 minute estimate. Already done at 7:26.


7:27 took less than 14 the next time I tried.

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1.  While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero.  This is typically explained in the following way.  While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare.  That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2].  Cabrera was utilizing a loop type of magnetic monopole detector.  Its operation is in...

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

Now available as a Kindle ebook for 99 cents ! Get a spiffy ebook, and fund more physics The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems , there seem to be fewer explanations of the procedure for deriving the conversion, so here goes! What do we actually want? To convert the Cartesian nabla to the nabla for another coordinate system, say… cylindrical coordinates. What we’ll need: 1. The Cartesian Nabla: 2. A set of equations relating the Cartesian coordinates to cylindrical coordinates: 3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system: How to do it: Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables. The chain ...

More Cowbell! Record Production using Google Forms and Charts

First, the what : This article shows how to embed a new Google Form into any web page. To demonstrate ths, a chart and form that allow blog readers to control the recording levels of each instrument in Blue Oyster Cult's "(Don't Fear) The Reaper" is used. HTML code from the Google version of the form included on this page is shown and the parts that need to be modified are highlighted. Next, the why : Google recently released an e-mail form feature that allows users of Google Documents to create an e-mail a form that automatically places each user's input into an associated spreadsheet. As it turns out, with a little bit of work, the forms that are created by Google Docs can be embedded into any web page. Now, The Goods: Click on the instrument you want turned up, click the submit button and then refresh the page. Through the magic of Google Forms as soon as you click on submit and refresh this web page, the data chart will update immediately. Turn up the:...
