  1. Ok. It blew yesterday, and it will probably sit around for awhile before I get to it. Thanks for the help.
  2. 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?
  3. 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?
  4. 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 ;))
  5. 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.
  6. 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?
  7. Are you triyng to find the capacitance of surface mount caps?
  8. 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.
  9. 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.
  10. Whats a 68000? I still have it so can get it off still.
  11. 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.
  12. 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.
  13. I used Maxim for the 555 and 556 timers. Ti also has them.
  14. 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.
  15. 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?
  16. 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.
  17. I just got my stuff from Maxim in the mail today. I ordered it on tuesday, 2 days to verify the order and ship!
  18. 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.
  19. 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
  20. 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
  21. 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.
  22. 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!).
  23. 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".
  24. 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).
