So I just blew up a cap on my speaker system for my computer... Made one hell of a sound. I don't think I have ever blown up a cap before (by cap I mean capacitor). Anyone have a really good speaker with sub solution for me? I'm apparently in the market for a new system....
So the quote above was posted Oct. 19'th and I have had this sub sitting in here since then taunting me. So I decided to go ahead and pull off the blown up cap and burnt up resistor and see if I can fix this sub system.
First thing I did was took my new Amtech flux (this stuff is awesome compared to the cheap crap out there!!!!) and fixed the two solder bridges I had on the board that caused it to blow up. This is what I get for soldering in a hurry. For those that don't know, flux will cause the solder to only attach to the terminals and makes it harder to bridge a gap. It will also make it hard to apply excess solder. But I cleaned up those solder bridges and removed the cap and resistor.
Next, I had to find a schematic for this system, and I actually found one, but I don't think it was this exact model. The reason I say that is because on the capacitor, it said it was a 1µf 20v, but what blew up was a 100µf 16v. So I just went with what was in front of my eyes and wrote it down.
The resistor is a little harder and I did have to go by the schematic and hope that is what I need. According to the schematic it is just a simple 1k ohm resistor. Cheap and easy.
I put both of those in my cart and less than $5.00 later they will be on their way. Lets hope I can get it up and running. Not sure what I'm going to do with the system when I do get it going, but I would like to get it going lol.
Always something going on...
Oh yea, replaced the capacitors on my washing machine that were dead and leaking and now the drain pump is locking up... ugh.....
Okay, this is now part 3 of this series lmao. Yea... "series"... ugh...
So you all know that I have had this old 2.1 speaker system on my computer for YEARS and the right channel ended up dying. So while I was in a hurry one day I decided to pull out the soldering iron and reflow all of the solder joints on one of the 3 boards in there. So I did that, I connected everything back up and
all channels were working, Right, Left, and the Sub were all working again. I'm awesome... Lets turn it up and get some bass going... "POP"
Then the magic smoke came pouring out of the sub where all the electronics live. I took it apart, again, and yup, a cap had completely exploded and a resistor was now black and unrecognizable. Well, I knew it was a resistor lmao.
That is where the second quote came in above. Found out the specs on the components and made two orders, one for the caps and on for the resistors. So now I wait.
A week after making the first order I receive the caps (only ordered two of them) but the resistors were no where to be seen. I contacted the seller (and opened up a case with ebay even though that is not what I meant to do, this time.... More on that in a sec lol) and he said "I'm sorry, I sent them out, they must have been lost in the mail. Unfortunately I'm out of stock of that particular item right now so I would be happy to refund your money". RED FLAG!!! I never received them and now you are "out of stock". I think you were "out of stock" and still sold them to me!!! Whatever, give me my money, I will go somewhere else.
So now we are a couple weeks after the initial order, I have the money back (like it really mattered, it was a little over a buck... Mmm, buck. Makes me want to cook up some back strap) so I make an order with a second company, twice as many resistors (I need ONE!!! lol) for the same price, so I order them. They said it would be delivered by Friday (today is Tuesday) so I sent the seller a message yesterday morning. I'm in america, they are shipping from america so I expect a return to my email during america's normal business hours. I wait, and nothing, no response. So, I open a claim.
By this time I'm pissed. All I need is some simple resistors to put on a board to fix what I had caught on fire lmao. Maybe the electronics gods are punishing me. Yea? Well I have a good one for them. hehe.
I know I have resistors around here which I purchased to bypass the VATS system on my wife's car. VATS is Vehicle Anti-Theft System. Basically it's that little chip in a key. Her chip went bad and I'm not paying $25 for a friggin key!!! So I bypassed it lmao. I searched all over for these resistors, but they are nowhere to be found. Then I see a bag of 5mm LED's, actually 3 bags, and since they are not native 12v LED's, they have resistors to bring down the voltage and the current so they don't blow up. Okay, they don't actually "blow up", they just fizzle out unimpressively.
There were two resistances in these packs, 460Ω and 560Ω. Okay, I can use two 460's and get close at 920Ω. Or I could put two 560Ω in series for 1120Ω. Or, just mix them and get 1020Ω. And that is what I did. The crappy thing is, now I have two resistors in place of one, which looks like crap but it's inside a box and you can't see it. But I still know it's there so my ADD sense (it's like spidey sense, but for things that need to be perfect lol) is going nuts knowing this. It looks like the resistors are having a rainbow party with the board. If you know what this is, shutup and don't say anything lmao.
So I have the resistors soldered in and I solder in the capacitor, cut all the leads, triple check for solder bridges, I'm good, it's time to test. I put it all back together and I set everything on top of my desk that way if it blows up my face is only about 8" from the output port of the sub lmao. But, I'm pretty sure it's going to be fine!!!
I wire it up and plug it into my headphone jack on the front of the computer tower and go go gadget youtube for some BASS. I don't care about the speakers, I care about the sub since that is the board that died lol. I find a 1:50 song and I let it go. Bass sounds good and yea BOI, I have both channels working so no more mono sound lol. So I crank it up and let that song play out. I hit another song with lower notes, it plays out, I hit a third song and, okay, the bass was a little too low on that one and was over extending the sub so it was hitting the grill so 4th song and oh yea, still working. I feel the back and it's starting to get warm which is normal and it's still going. My neighbors thought it sounded to good they invited the local sheriff's office over to enjoy it with us.
Okay, not really but I saw that joke on one of the youtube comments and thought it was pretty funny lol.
But dammit, it works and that is all I care about. It has been sitting apart and blown up for far too long. Of course I have this new system under my desk now so I have no idea what I'm going to do with my old system that I just fixed lmao. I guess it's time to move it away from my desk to make room for more clutter. lol.
Yes, I thought about putting all of this on video, but my personal channel doesn't get any hits and speakers are not really RC related so I just skipped over that. If I can get some chargers or whatever that have went bad, and I can fix them, I will definitely make videos on that to post to the channel. Man I miss making videos...
