This is a wired remote for Canon DSLR camera.  It's used on the Canon 1D, 30D, 40, 50D, 7D etc.  This cheap generic canon RS-80N3 wired remote has failed on me after about 2 to 3  years of infrequent use. Pressing the button did not create any response on the camera. I suspect there could be an open circuit somewhere in the remote.  The plug on this cheap remote are also very loose when connected to the camera. I found out that this cheap remote’s plug is lacking an additional outer ring that helps the plug to fit snugly into the camera’s remote socket. Here's a quick side by side comparison of the plugs with my Pixel wireless remote adapter cable (on the right). The wireless remote that i have is similar to this model: Since this unit is not working, let’s have a look inside the remote and see how it is put together before i throw it into the Ewaste bin. One of the unique thing about this remote is that it does not use a standard el...

Came across this Fujitsu USB optical mouse some time ago and found that it did not work correctly. The left mouse click seems to be electronically lock on the mouse controller when it is connected to a computer (windows PC). It’s seems like this mouse is destined for the recycling bin. Before I do that, I thought it would be interesting to disassemble the mouse and see if there is anything interesting inside. And here we go: Here’s the Fujitsu USB optical Mouse model HLMSE0038A-00. Here’s the bottom of the mouse. After disassembling the mouse, from the left to right: The PCB board, single self-taping screw, scroll wheel, plastic optical prism and lens and the 3 pieces of plastic mouse enclosure. A close up look at the mouse internals. Close up of the mouse PCB board(single sided board). And lastly, the PCB track layout side. Hope this will be useful to someone out there..:)

If you need to separate/demux the audio, video or both of the components without re-encoding from a mp4 file, here is a simple way to do it using the VLC player open source software (Download VLC from their official website: https://www.videolan.org/vlc/index.html ). In this example, I will be using the VLC version 3.0.1 64 bit windows version of the VLC player to perform the extraction/demux. I believe you do not need to have the same exact version in order to do this. I have tested this method using an older 2.2.4 32bit windows version and it worked fine. The following example are for audio extraction. For video extraction, it should be somewhat similar. In order to extract the original format out from the mp4, the first step is to identify what are the individual stream made of. You can use the following method to identify them.  - Load your source mp4 file into VLC player.  - From the top menu, goto Tools>Codec Information. You shoul...
