Huwawei HG658 and Network Switches

Hey Everyone~

While upgrading our network recently to support more computers over ethernet. I decided to buy a switch to extend our limited modem / router. Curiously it never worked at first and during a call to our ISP I was able to fix it while I was fiddling about (I told them how I fixed it but I doubt they will be suggesting the fix to others so I figured it would be helpful to post about it just in case).

For the life of me I can't imagine why this is a thing, but in the case of our modem which happens to be provided by our ISP; a Huwawei HG658 to be specific. The way I was able to get the switch to work was to plug it into the second port instead of the first. So if you happen to have the same problem (assuming this affects other modem / routers), just switch from LAN1 to any other port like LAN2 and it should work :)

Hope this helps people and if anyone knows the reason for this I would love to hear why!

Held back with no Good Reason

Hey Everyone,

You know when you have that moment where if you don't take a chance you could lose that moment forever? something you simply can't get back unless you had the convenience of a time machine? missing the last bus so to speak. Well there are many many things that we lose each day without any good reason due to a bizarre mentality from a bunch of callous, selfish and backwards people who can't seem to see what they have caused and continue to cause each day; they are their own enemy.

This mentality locks up knowledge that everyone should have the right to access without some kind of exuberant fee or VIP pass, knowledge like mathematics and many other fields that for some reason they don't want people to know, but them; possibly derived from an arrogant elitism: you can't copyright the laws that govern our universe and we would be far better off if such information was open to the public. Many, many things could be solved in our world if the right person sees the right information, at the right time and does something with it, it bothers me how many moments have been lost due to this keeping back of information and assuming that you need qualifications and a diploma to make a difference, how many diseases could have been cured and many lives saved or simply improved as a result if only the right mind was spurred with the right knowledge. Keeping it locked up only slows our development as a species and prevents creativity, involvement and competition to make our world a better place. Academics have lost their creativity and ability to think beyond the standard rules because they forget that the standards are simply a current approximation of known variables; it would be arrogant to think otherwise. What's worse is most of the people in control of the information are too close to the information to be able to think outside the square which happens to literally every field out there and they tend to forget this side effect of the human mind. There's a humming of potential just outside the doors, just open them and lets us in and watch the magic.

Some things that people might consider trivial are also effected, for example; they lock up games, music and movies, including many other things to the point of no recovery. The only reason we still have any today is due to a bunch of what should be hailed as heroes of the IT field; people who hack and crack DRM so that our cultural entertainment isn't lost to the void. Most companies bull**** this out of proportion; aka lie, in order to make them appear as the victims even though statistically the loss of money due to piracy is microscopic at best; usually only around a few percent or less and make substantial profit while destroying the image of a geographic who are saving our world from losing what we care about. These people are shunned for breaking the code and allowing us to enjoy our games and music again even though the companies have no desire to preserve them or to give us ownership of which we bought. The amount of talent and skill these people have is remarkable, they have so much experience within the IT field that any company would be foolish not to hire them, resulting in better software, better service to the user base. Everything simply improves including, ironically, the company's income.

Did you know that most people who pirate actually end up buying the products anyway? the irony is that piracy is one of the best forms of advertisement in the world but companies are too stubborn and arrogant to see it and prefer the more dishonest way while making enormous amounts of money in the process all the while making these amazingly talented people look bad.

The reason and cause behind the shoddy attempt to manhandle the internet, also known as SOPA and its continued remakes with just the name swapped for another acronym, was caused by these exact kinds of companies who only desire profit while not adapting to modern standards; they don't care about freedoms and are willing to sacrifice ours just so they can get an extra buck from the government or their own plans. What's worse is these people are living hypocrites who pirate software and music while trying to force a law against it, thanks to the Anonymous hackers we now know they did this. SOPA wasn't just for their agenda, it was also an excuse for the government to police society due to internal corruption which would violate any and all constitutional rights that many cultures have developed in developed areas; DRM for the internet basically. I can't even comprehend why these companies even try, all it shows is a clawing, desperate attempt to hold on because they seem completely incapable of adapting to the future and making money honestly while giving us quality products that we can hold and own ourselves.

DRM is completely and utterly useless, it costs thousands to maintain and all it does is cause suffering for many people as a result; even to the point of trying to take away our very freedoms which many many people had to fight off including myself; literally the internet fought back and showed how foolish the people are who tried to hold back society and how utterly ignorant they are of how the world is developing; the very thing they are meant to uphold and maintain the rights of.

Internet is one of those remarkable things that no one has the right to control; I can't even begin to formulate a sentence to describe just how important it is: literally as important as breathing air to be completely honest. It brings us together regardless of what language we speak or where we live; breaking the cultural barriers and destroying everything that is bad in society like racism, sexism, corruption etc. It give us a voice to speak out to the world and our governments without being pushed or shunned away, to share opinions and to find others like ourselves; it's fundamentally important to our way of life and for the future. It needs to become a freedom that everyone can enjoy without having to pay money, nothing is going to stop it and it's only going to get better and better and better.

Repaired my Laptop's Power System Today

Hey Everyone,

There's nothing worse than a computer failure especially if the computer itself is fine but you can't recharge it and turn the thing on.

Recently my laptop stopped accepting energy from the power supply; lasted a good year and a half before this. It took a lot of fiddling to get the recharge light to turn on so I could use it but after a little while even that stopped working, I tried to De-oxidize the connection surface by cleaning it with some alcohol but even then it still didn't work.

When I was younger I had a tendency to take things apart; I was very curious of how things worked, sadly at that time of my life I had a habit of not putting things back together but thankfully I've learned better since then.

I decided that it was time to repair my laptop once and for all; by completely replacing the power connection inside, I had some spare electronics that was no longer of use that had a power socket which was compatible with a plug I had lying about so I De-soldered it from the board. It took a while to open up my laptop; finding all the hidden screws and storing them away safe so I could put everything back together eventually: I had actually opened my laptop a few times before this out of curiosity so I got pretty good at opening it this time. Once I had opened the laptop I unscrewed the power board and detached it, I aligned the new power socket up for comparison and it looked like it would fit inside perfectly so I began work on the power system. I detached the old socket and aligned the new one up, soldered it on and made sure everything looked ok.

Here you can see the new socket attached and the old one on the right:


After the new socket was successfully attached I discovered that one of the surface mounted components had disintegrated into powder under the heat of the soldering iron, it was just too close to the socket. I needed to know what I destroyed so I could repair it, I performed a continuity test and one side connected to positive and the other to ground which indicated to me that I had destroyed a small capacitor used for smoothing out the power coming in. I got out one of my 0.01uf micro farad capacitors albeit much larger than a tiny surface mounted one and attached it on the other side which had much easier to access connections that the ones the original component was using.

Here you can see the new capacitor attached and ready to go:






Once everything was soldered I double checked everything and placed the board back inside the laptop making sure to attach all the wires. I aligned it up and began to screw it back in place and thankfully it fit like a glove, here you can see it back where it belongs:















I hooked up the power supply to my new plug, it's one of those power supplies that support multiple connectors that attached to the end so I had to adapt my connection to it. I made absolutely sure that it would not break for a long time by layering heat shrink as these kinds of connectors have a tendency to break and bend otherwise. Here you can see what I came up with:




It worked! The charging light is lit and I have power again:



Sure beats the thought of buying a whole new laptop.

Orange Blue White

Hey Everyone,

Ever since I was a kid and sat in the back of the car as my parents would drive me about I simply loved looking out the window at the trees and the clouds in the sky, I also enjoyed night time when all the street lights were lit; mostly orange though some are white and I could have sworn I saw a green one. A fun little thing I discovered was If you look through the blue sun strip built into the glass at the top and watch the orange street lights through the glass, the moment an orange light would pass through the strip it would turn a shade of white.

I always found it fun and fascinating even though I understood at that age that the sun strip absorbed the orange light and what was left behind combined with the blue of the strip formed the white colour but it's small things like that that kept me thinking and helped me develop my analytical mind for the future. I always enjoy remembering the things that influenced me as a kid; no matter how subtle or what some might consider meaningless.

Repaired my Brother's Stereo Today

Hey Everyone,

I guess I'm kinda documenting what I've done here and there in my life on this blog; wasn't sure what I was going to end up posting here initially. One thing I enjoy doing is helping others with problems and doing everything within my ability to fix things before the unnecessary move to buy entire replacements which can cost quite a lot of money. I learn from each and every experience regardless if I fail; usually caused from over complex parts that are almost impossible to repair due to strange design choices to save money or overly complex moving pieces which I can't replace unless I had tools like a CNC or Laser printer to print new parts which cost easily within the thousands to tens of thousands of dollars.

Recently my Brother found that his stereo system wasn't allowing audio to reach the speakers after the head set was unplugged due to the headset mute feature and even when they were plugged in it required a lot of fiddling with the connector to get sound through the headset. I took an educated guess what the problem might be and headed outside with my tools and the stereo. After a few minutes I had the casing removed and examined the inside for damage or lose wires but I couldn't see anything wrong with it so I immediately went straight to where I thought the problem was; the stereo socket for connecting the headset. After carefully dismantling all the pieces that held the machine together and keeping the screws safe I finally reached the socket, I detached the circuit board it was attached to and immediately saw the problem; all the solder joints were visibly detached so it's no wonder why my Brother had such trouble getting it to behave.

Here you can see where the solder has shattered:


Stereo sockets can come with an optional extra connection that can be used as a switch to detect the presence of an attached plug from a headset which the machine uses to know when to mute the main speakers. Since the sense line was unattached the stereo system defaulted to assuming a headset was always attached; the switch inside would normally be connected until the plug is inserted causing a break in the connection, the fact that the solder was broken caused a permanent break so there was no way for the machine to know that the plug wasn't inserted anymore resulting in a permanent mute. As a fun side note to this you could attach your own switch to this sense line to create a custom mute feature and the option to have sound come through both the headset and speakers at the same time.

I got out my soldering iron, some spare solder and got to work replacing the solder joints with new solder making sure the socket had a nice and strong connection to the circuit board again. After I repaired the solder joints I partially put the machine back together just enough so I could make sure it worked before screwing everything back in and immediately I could hear sound coming through the speakers again. Turns out I was correct from the start and now my Brother can listen to music again; either through the headset or speakers without the need to waste money on a new stereo; at least for the time being.

Here's the end result of the circuit with a new set of solder:

Creativity at the Most Inappropriate Time

Hey Everyone,

This is just something I experience but wanted to share with other people who may not be aware of this.

I never knew that this was a semi-well known thing since it was something I discovered on my own; but there is a curious time just before you go to sleep when your really tired; it's almost like the brain can dedicate all its energy into one specific task, the task in question is raw creativity; the ability to imagine. This might also be related to the hyper active thinking which can lead some people to insomnia before sleep when you just can't stop thinking of stuff. I actually found an article recently that from memory said "Back during the ancient period of our species we didn't have much up time; the bed was regarded as an important location (which I take to heart since I love sleeping too) they noticed this phenomenon and called it the hour of creativity / imagination." At the time of writing I can't find that article so I'm most likely miss-quoting. There's a few articles out their that associate sleep with increased cognitive flexibility due to the way relational memories are integrated into your long term memory during REM sleep but that's related to unconsciousness whilst my post is a complementary to that in the conscious state.

Interestingly enough I would have guessed the imagination centre of the brain took a lot of brain power, probably from that fact that you can imagine pretty much anything and gives off the illusion that it is taxing on the brain but from further evaluation I've realized that it actually takes extremely little, either that or the pathways of the brain that allow you to imagine are easy for the brain to access without additional energy which is why it's all you are left with before sleep. Pretty much any additionally complex part of your brain's abilities besides seeing, smelling, touching and hearing takes a lot of effort to re-enable like trying to budge a heavy door to open with rusted hinges. When I am within this zone I'm so tired I could just drop at any moment but amazingly I can imagine things much clearer; with higher vibrancy and detail etc without much effort at all like a movie that I can direct. Things just flow so naturally that I use it whenever I can to improve the stories I write as well as refine things I've been working on.

So the next time you are at that stage where you just want to lay down and sleep the night away; no need to worry about falling asleep during this moment: just lay there and have a go at day dreaming, thinking about your art if your the artist type? or perhaps the story you've been writing? your current musical composition? what ever you want and see if it flows easier for you too. I can only speak from experience so this may not work for everyone but have a go just in case as it's an opportunity one shouldn't miss, you might be pleasantly surprised. Just remember to leave a notepad with writing equipment nearby or your ideas might keep you up all night.

Ironically it comes at the most inappropriate time, go figure.

Thanks for reading,
Ashton.

Repaired the Dishwasher Today

Hey Everyone,

One of the things I like to do around the house when something breaks is make absolutely sure that the thing that breaks can be fixed before writing it off for scrap and spare parts. Today I found all the cutlery and plastic in the dishwasher bent, burned and pretty much destroyed. I thought about how that could have happened knowing that it couldn't have been an acid from the dishwasher powder since plastic is immune to it so the only thing it could have been was heat.

I took out everything including the sliding draws so I could perform a test run. After a little while I noticed the distinctive sound that I always heard was gone; the loud grumbling noise indicative of the pump below. I opened the door after a minute and the heating element at the bottom was red hot but not a scrap of water was shooting about to cool it so something had stopped the pump from working.

It took a little time to disconnect it from the water and power before pulling it out from under the kitchen bench so I could examine it in detail but once I had it out I could get to work. I removed the front panel and examined every part of the circuit looking for burned out components or some sign of what had happened to it. The relays had a little singe but that was to be expected since the machine was 10 years old and I knew they were working as I tested the machine again with the relays visible. I took the circuit diagram, traced it to the main pump and found it connected to the second relay on line L1. I followed the wires and found one of them had snapped due to being unnecessarily tight against the corner of the metal frame; all the other wires seemed fine and not under stress, I grabbed my heat shrink, soldering iron etc and set to work.



I reconnected the wires back together making sure to heat shrink both sides and ran another test, this time I reconnected the water and the pump started up just like it had for the last decade. When I opened the door it shot water at me and drenched me completely; guess I had the water turned up too high.



After re-attaching everything back to the frame I slid it back under the kitchen bench and screwed it back in to the wooden frame. I added a few more screws here and there for good measure and in just a couple of hours I had a working dishwasher again and saved a lot of money too which is always nice. :)

Ashton.
