    TRIMMING AN AVI FILE. THE FILE SIZE EXPLODES

    The trimmer I use appears to be part of Windows 10 editing app. I call up photo or video file into "photos" app and click on edit & create › trim. I have GIMP which I believe is active. Also PIXIO but that may be disabled. I am not sure if either editor does video editing.

    WILLY LOMAN WAS JUST TOO DARNED ETHICAL

    That is too funny and too disconcerting at the same time. My earlier rant stems from what one might think is a problem in language translation. I will guess that 50% of blurred meaning can be attributed to an honest lack of translation facility. However, I think many vendors, salesmen, and sales...

    TRIMMING AN AVI FILE. THE FILE SIZE EXPLODES

    I made an audio/video recording with a fuji digital camera. I copied the file from the camera to my computer. The recording is 26 minutes in length with a file size of 1.79 GB. I trimmed a section out that I want to use. The trimmed avi is 2 min 45 sec long with a file size of 2.16 GB. What...

    WILLY LOMAN WAS JUST TOO DARNED ETHICAL

    No worries Willy. Grab your satchel and let's hit the road. The 21st century salesman has no obligation or accountability. Dazzle em with details or baffle em with bullshit. Make the sale trumps all rules that may have once applied. Get in soon tho. The hucksters and shysters will soon out...

    WELLCAM: ROUND 2

    Yes, I did mix two projects here. I strayed off on a tangent. One project is the Wellcam. In this project I would like to find a relatively inexpensive color video camera. I have noticed that medical procedures are a big user of cameras on flexible instruments. It has been my observation that...

    WELLCAM: ROUND 2

    There is a cell tower within 6 to 8 miles but I am not in "line of site". I was under the impression that repeaters were off the shelf devices. I may very well be using the wrong term. One that I have seen was Wilson brand.

    WELLCAM: ROUND 2

    Thank you Harold, I will look into it. The camera still has to be mobile and scenes viewable while it is 400 feet below grade, down an eight inch hole. On a related matter, I need to set up some surveillance cameras on a distant property. Unfortunately, it is my impression that WiFi is...

    WELLCAM: ROUND 2

    This project is in the que and approaching rapidly. My last efforts regarding this project, resulted in quite an acquisition of knowledge related to video workings. An off the cuff WAG, concerning my first attempt at fabricating an acceptable remote camera system, is, the DC level of the video...

    Connecting non-solderable wires

    I have considered trying silver solder but have not yet attempted it. What is ballpark temp required for silver soldering? I do recall that MAPP gas was required for the silver soldering. Regarding cadmium; is that a silver solder laden with cadmium? I seem to recall that cadmium is very toxic.

    Connecting non-solderable wires

    I will be trying to fuse copper wire, 22 gauge stranded, to nichrome wire, 22 gauge solid, Melting point of nichrome is approximately 2550 degrees F, melting point of copper is approximately 1980 degrees F. Is this difference of nearly 600 degrees in melting points going to be a problem? I don't...

    Connecting non-solderable wires

    Thank you for your suggestion. The connector you are describing sounds to be what I refer to as a "wire nut." If it is indeed what I think it is, they come in a wide variety of sizes. I use large ones for house wiring, motor connections to power input lines, etc. Unfortunately the connectors...

    Video monitor cable adaptation

    I did find an S-AV to VGA converter online. I have hooked it up and it works quite well. Unit sold for $5.99. Today I went to "My Orders," clicked on this device, then clicked on "Buy Again." Device was priced at $8.99. A little odd about the price increase I thought. Thank you for your previous...

    BATTERY RECHARGING DETAILS NEEDED

    Salvage is a billion dollar business opportunity. I still like the idea of launching a capture device to bring sats back to surface, under control. What's the count now? Approx 650,000 orbiting drones? Sorry, a little off topic.

    BATTERY RECHARGING DETAILS NEEDED

    Both the charging modules and converter modules are nicely priced. Thanks.

    BATTERY RECHARGING DETAILS NEEDED

    Compact size is always a consideration. The initial enclosure I used has dimensions of approximately 1" X 2.25" X 4". This size does not allow for use of any standard battery holder. Six AA cells taped together fits nicely and leaves a little room for circuitry and controls. Battery pack size is...

    BATTERY RECHARGING DETAILS NEEDED

    Good info. Thanks. For some lighting applications that I have developed, my needs are for a 9V battery pack. Six 1.5V alkaline cells work great but when batteries are spent, I would either have to have battery pack returned to me or expect consumer to make up cost of battery pack enclosure...

    BATTERY RECHARGING DETAILS NEEDED

    I religiously used Duracell coppertop AA cells in my Fuji digital camera. Excellent performance. I most often replaced the 2 cells when low battery indicator was midrange. The partially spent alkaline cells would read 1.37V to 1.40V, no load. I spent tens of hours trying to develop a...

    Video monitor cable adaptation

    Very nice device. Better yet, if I can locate a similar device which will convert my single "analog" signal to VGA, I will have my remedy. In a prior instance, I plugged my signal into, I believe it was the yellow panel jack, intensity I think it was, and acquired a usable video display. Not top...

    BATTERY RECHARGING DETAILS NEEDED

    According to the discharge graph,( 750mA draw ), the voltage drops from 1.45 to 1.25 during the first 20% of use, then meanders around 1.25V to 1.18V for the next 60% of time in use, then plummets to 0V in a short time. Probably why my single cell battery is rated at a 1.2V output.

    BATTERY RECHARGING DETAILS NEEDED

    I'm thinking 4.5V is lowest charging voltage. My NIMH cells are rated 1.2V so I figure 1.3V full voltage which equals 3.9V. That leaves .6V ÷ 3 = .2V. That sounds about right for a reverse voltage breakdown level 1.4V per cell.
