I am going to scrap my old computer monitr. Its 7 years old and just blew today. I know the cathode can really shock you, but is there anything I should look out for? Is there a way to discharge the cathode? And another question, when working with high voltages, are you supposed to be grounded or not grounded? In a welding class in school I am taking they say not to be grounded(we are doing arc welding right now), I always thought you ARE supposed to be grounded?

My friend wants to use his cars subs for his stereo. I know a more then most people around here(my family and friends) about audio and audio setups. But I dont have a car yet so I havnt delt with that much so I cant answer his question. Would he just hook them up like a regular sub or would he need converters and/or amps?

It seems that the dollar stores with good stuff are usually the closeout ones, not the big chain ones like family dollar or dollar tree. I havnt been to a goon one lately because I have been busy, but when I go I willjust about anything I think I need or may need in the next year(I plan ahead ;))
-
Yeah, if there is enough wire then I will take it. I got a ton of wire from some old printers once. But my best find was a $1(dollar store) cable, it was a printer cable but it must have had 60 around 30g wires in it, and the cable was like 8 feet long so I will be good on the small wire for a long time.

I scrap electronics, my last one was a vcr. I got a ton of capacitors, and some diodes. I usually dont bother with resistors or surface mount unless I know I need one then I check to see if its there. I know just about everything I got except some of the stuff from the power supply. There is a pretty big thing that looks like a transformer, but i am not sure. Its black and wrapped with 4 rows of wire, and has 4 leads(2 on each end), and the number 10943 written on the side. I Have one thing that I thought was a huge transistor, until I saw it had 5 leads. It has a number on it: STRF6552. What is it? I searched google but didnt find pictures and many different prices(from 50c to $40). I have some other stuff, they look like electrolytic capacitros except they are totally round, solid black, and have a dot then 100 on one, and a dot and 330 on another. Could they be chokes? I have some other stuff but dont want to describe them because I will suck at it. I will try to get a pic of everything somethine, but for now do you have any clue what I said so far are?
-
Are you triyng to find the capacitance of surface mount caps?
-
Not trying to screw companies or anything, but return it and tell them that it just stopped working and get a diferent one. You could have blown anything in there, would be very hard to fix unless you can see something burned or something obvious.
-
Mouser has the SMD resistors, but not transistors. I know ebay has SMD transistors(the common 2n2222, 2n3904, 2n4401 ect...). You can check futurlec.com, and digikey.com.
-
Whats a 68000? I still have it so can get it off still.
-
I just got all of my stuff ftom TI, and its all surface mount. I dont think I will get much use out of them, but I will try.
-
Yeah, you have to make sure you know what you are getting. I got all standard ones, but on purpose I got 10 surface mount just for testing.
-
I used Maxim for the 555 and 556 timers. Ti also has them.
-
Go to the top post in this forum, it says something like "free chips". Just find what you want on the company site and order. But you need to find a button that says sample.
-
I made an order for samples, I got some 555, surface mount 555, and 556 timers. What should I do with them? Anything fun to do? Anything useful?
-
I am going to make the Minty Boost, but cant find the diode or the inductor that it needs. The diode is 1n5818 and the inductor is 18R223. I have some 1n914 diodes, but can I use them instead? I need stuff that I can get at Radio Shack because I am not making an order online for 2 parts.
-
I just got my stuff from Maxim in the mail today. I ordered it on tuesday, 2 days to verify the order and ship!

I just took apart an old Sega, there were 31 capacitors, took them all, and they are all 10uF, 47uF, and like 3 100uF. I need all the 10uF and 47uF for other things I do so that worked out well. I am on an old VCR right now, I have a bowl filled with caps. I dont bother with surface mount, and right now I am getting to the power supply and I have to be very careful of all of the exposed stuff. I wil write back later and tell how much stuff I got, and if I get shocked.
-
Ok, I will check them out. After I posted that, I checked Mouser, I got everything except for the transistors which eBay has. But I didnt pay for anything so I will check Philips(do they have free smaples?). Since I have never used SMT, what program should I use for making a PCB? Thanks
-
I am looking for 470 Ohm resistors, 4.7 Ohm resistors, 1.8 Ohm resistors, 10uF capacitors, and any one of these transistors, 2n2222, bc547b, 2n3904, 2n4401. I dont know what the kind I am are using are called, but they are the ones with leads. I need to save some space and switch to surface mount. I have searched for surface mount stuff that I need, but cant find it because its gets confusing with all of the choices. What site would be best for surface mount? Oh yeah, the resistors would be 1/4 watt, the caps would have to be anything above 5v. Thanks

There was one site on the first page of this topic(says that it only passive devices next to it). I like to see what I am ordering too, so I dont use mouser or digikey, I use www.allelectronics.com. I was thinking today about how radio shack turned from an electronics store to a crappy toy/cellphone/tv/stereo store. I saw pictures of the begining stores, and in one of the Short Circuit movies and it was awesome. Too bad that I am 15 and didnt use radio shack when it was better.
-
I just take stuff apart because I know somewhere down the road I will be looking for something that radio shack doent have, and dont want to order online(I start off with a $5 list and end up with $50, I cant stop!).
-
Am I the only one that takes apart broken or stuff for the garbage and takes the chips, transistors, capacitors, resistors, chokes, coils, and wire(if there is enough)? I used to take apart old printers that we had and just take the LEDs, but now I take just about everything(except SMT). I dont use all of it, but I have already used some(capacitors and a resistor). My VCR just crapped out, makes blue screen but will has audio, so I am going to scrap that pretty soon. An old monitor that we have is just about dead and ready to upgrade to an LCD, so I might take that for parts. I dont know if I want to mess with the cathode in it, dont feel like getting killed too soon, I can just see the news headlines "Cheap kid gets killed when trying to get $1.50 of electronics".
-
I dont really need chips, I need more passive stuff. Do any of those companies offer resistors, capacitors, pots and that stuff? I am also looking for some transistors and diodes that I cant find at my local radio shack (radio shack sucks).

Ok. I tested it and it works great. Thanks alot!
Any safety tips for opening a computer monitor?

Ok. It blew yesterday, and it will probably sit around for awhile before I get to it. Thanks for the help.
