    Your suggested method of cleaning sounds good, just remember to try and not leave any lint behind from using the swab. The alcohol dries pretty quick too so that is helpful. Every now and then I remove all the covers off the back of my notebook (Acer Aspire 1751) and use my air compressor to blow it out. It has removable covers for the drive, ram, battery and a M.2 sata that come off. Just got to make sure to not spin the fan off the moon when blowing it out. Been there, seen that, got the T-shirt. Good Luck.
  2. Good Luck. Guess you could look in some of the tech magazines for someplace to start.
  3. I was sort of under the impression there was not such thing as "ethical" hacking. Computing and technology Computer hacking, including: Hacker culture, activity within the computer programmer subculture Security hacker, someone who breaches defenses in a computer system Cybercrime Phone hacking, gaining unauthorized access to phones ROM hacking, the process of modifying a video game's program image
  4. According to the chart at the website above, the total resistance of 18 gauge wire is only 6.385 ohms per 1000 feet. That's pretty low of something 1000 feet long. Since the wires are in parallel, it would be half that, so theoretically the total resistance would be only 3.1925 ohms per 1000 feet. Surely not too much and that is for 1000 feet and you are only going 50 feet. Personally, I wouldn't bother with it anyway given the small resistance and the short length of the total wire. When I went to school for my electronics degree (https://www.redwoods.edu/) I had to come up with a project of something that I could build from scratch and demonstrate that it was safe to use and I had to demonstrate it to the instructor. Since I am a fan of the old black and white monster movies, my first idea was a jacob's ladder. The instructor shot that down real quick so my second idea was a tesla coil (https://en.wikipedia.org/wiki/Tesla_coil). During the construction of the coil I used 1000 feet of 22 gauge wire around a 4 inch diameter piece of PVC pipe. That was for the secondary coil. For the primary coil, I used 1/4 inch diameter copper pipe, 28 feet long. I used spare parts for the rest of it, one of them being the PSU out of an old PC. At first, I was worried about the total resistance of the wire on the secondary but in the long run it really didn't amount to anything. We had a blast with that thing when it came to doing my final presentation. Unfortunately, after all was said and done, I had to dismantle it for safety reasons. The instructor didn't want anyone to plug it in and turn it on if they didn't know what the hell they were doing. But I did keep the secondary coil and it is in a box out in the garage. To make a long story short, you can solder the wires just like in your drawing and that is fine but considering the short distance (50 feet), I wouldn't worry about it. Good Luck and let me know how it goes.
  5. Lemme see if I got this right. You have 4 wires and they are all of equal length (say 50 inches) and size (12 gauge). You take 2 of the 4 wires and solder them end to end, and then when done with that, you take the other two wires and solder them end to end. As a result, you now have just two wires of equal length and size. Is this correct? If that is correct, lets assume the original 4 wires measured 100 ohm each (4 x 100 ohms). Then you take the first two wires and solder them end to end. That would make one longer wire of 200 ohms (2 x 100 ohms). Then you do the same to the other two wires also making a single wire at 200 ohms. So now you have two longer wires 100 inches long at 200 ohms each. Then you take the two wires of 100 inches at 200 ohms and solder them in parallel. So what you have now is 1/2 x 200 ohms for a total of 100 ohms over the total length of the wire. When you solder two wires of equal length and size you essentially are creating just a single wire out of the two because all the specs on the two wires are identical. Now, lets get back to the original 4 wires (50 inches long, 12 guage, 100 ohms), and instead of soldering them together to make two wires, we solder them all together to make just one wire. So, essentially, we have one wire, 50 inches long, but it has four "legs". (Sorry, couldn't think of a better word for it). Since there are now four legs to the single wire and they are connected in parallel, we figure the total resistance as 1/4 (4 wires) times the total resistance of just one wire (100 ohms). So, 1/4 x 50 = 12.5 ohms). So, four wires of equal length soldered in parallel in this case would equal just 12.5 ohms total resistance over the length of the 50 inches. For some really helpful information about how much resistance is inside a given length of wire at a given size, I found a place that has a LOT of great information. https://www.powerstream.com/Wire_Size.htm Let me know if I can be of any further help. If you want more help via email, I can do that too. Just click on my information and you will find how to contact me via email. Once again, glad to help.
  6. DVD Collection Software

    I believe he was sort of trying to avoid having to type in every single dvd title. That is why he is looking for something with the possibility of using a hand-held scanner. Found one called Collectorz but don't know if it uses a scanner.
  7. DVD Collection Software

    Yea, forgot what it was called. Thanks.
  8. I have a client that has an extensive collection of DVD movies. He approached me looking for my input on a DVD collection software package so that when he goes shopping for another movie, he can check the software to see whether or not he already has a particular movie in his collection. He currently has over 500 DVD movies. Anyone in the forums use anything like this? Maybe something that he can maintain the collection on his Windows 10 based PC while also maintaining a copy of the collection on his iPhone for use when shopping. Also, a hand scanner would be nice so that he doesn't have to input the names and UPC bar codes manually. Many thanks.
  9. [HELP] Electromagnetic Waves

    Just trying to figure out how I could draw a pic of a SSB wave and trying to explain how it works. I guess the best way to draw it would be to draw a full sine wave then cut or erase the bottom half of the wave away. That works for the pic, but in layman's terms I'm still trying to come up with the best of simple solutions for someone to understand that does not have a history of studying or working in electronics or communications.
  10. [HELP] Electromagnetic Waves

    Something tells me that it's a good thing that single-sideband (SSB) wasn't brought into the conversation.
  11. Although I agree with most of what is said here, there are things to consider. Are the wires of equal length? Are the wires equal in size, ie: 12 guage or 14 guage? Are the wires soldered in parallel or are they soldered in serial? For example, lets say the wires are identical in all ways. Same length and same size. Also given is the total resistance of just one of the wires = 100 ohms, therefore, the resistance of both wires is the same. If the wires are soldered in serial (end to end), then the total resistance of the wires would be 2 times 100 ohms or 200 ohms over the total length of the wire. If the wires are soldered in parallel, (side by side), then the total resistance of the wires would be 1/2 times 100 ohms for a total of 50 ohms over the total length of the wire. I know my answer is a little long winded but I wanted to make sure that you understood the reason behind the answer. That way if the question ever comes up again, you know how to figure it out for yourself. FYI, if there are four wires of equal length and size and each wire measures 100 ohms, then in series total resistance would be 400 ohms, but if they are connected in parallel, then total would be 1/4 times 100 ohms or 25 ohms total.
  12. Decent molex cable?

  13. Need help to verify if phone is new

    I would put my money on that not only is it NOT new, there is a good chance it is STOLEN.
  14. Looks good to me from where I'm sitting. After I got them hooked up and verified that all is correct, I put a bit of hot glue on them to keep them from coming loose.

    Is there a possibility this post is in the wrong place? Not to mention that black text on a black screen makes it hard to read.
