Snork Posted January 8, 2004 Report Share Posted January 8, 2004 oh my GOD! i just bought 3000 blues for 10 bucks on ebay. they are like 1 cent in japan. so suppliers in america that get a deal on them from japan sell them uber cheap on ebay. check them out. i also have 5000 green. 1.50 EACH that is REDICULOUS MAN! cold cathodes also are a great light source plus they are thing. it would be perfect to put int the russ rod channel Quote Link to comment Share on other sites More sharing options...
krazyderek Posted January 8, 2004 Report Share Posted January 8, 2004 that's cool dave, thanks for the link, although it looks like a school text book *cold shiver*.... so the only thing missing from my diagram is a resistor? (and of course the proper power source) ? on a side note i was actually thinking about taking electronics technician at a colledge next sept.... what's it like anyways?

daveq Posted January 8, 2004 Report Share Posted January 8, 2004 I'm not sure. I did the four year deal for the EE degree. I think the two year will actually be a bit more useful in terms of learning things other than theory. There was a ton of math (calculus I, II, III, IV, ...). I didn't mind it but some people hate math. If you like electronics and don't mind math then I would say do it. Nowadays web development and database software are the biggest employment opportunities though. I guess it depends if you are a do it because you enjoy it kinda guy or do it because you want the $$$ kinda guy. Some people are lucky and enjoy what they do and have it pay well also. I think the diagram would need to show the resistor and power source - yes. If it were similar to my circuit, there would be a resistor in series with each LED. It's not mandatory that you do that - just one way. The value of the resistor depends on how much current (which affects the brightness) you want flowing through the LEDs. Each color LED usually has a slightly different max current and voltage spec. They are usually in the range of 3 - 5V and 10 - 30 mA. So if you have 12 LED's, at 10mA each - that's 120mA through the system. For a 9V which has a typical mAH of 500, you can see how short of a life your battery will have. There are some real nice Lithium batteries out there with much higher maH ratings. Of course, they cost more. I use 4 AA batteries (~1000 to 2000mA each) which is why I was asking about an AA battery box a while ago. There's more to it than it appears for a beginner. Once the theory has been understood - it's onto the implementation. That's another learning experience. By the way, I don't think it's a coincidence that SIMS doesn't show any of their installation pics or talk about the power supply or circuits they use. For $600 a fretboard, they want to keep this stuff secret. They don't want people installing them in new boards themselves. Quote Link to comment Share on other sites More sharing options...
krazyderek Posted January 8, 2004 Report Share Posted January 8, 2004 i can't do something i hate...screw the money...... i get mega cranky after a couple of weeks... then just stop going to it (work or school course) although i like playing with wires, i did the phone system in our house, not the most complicated thing in the world of electronics but ya, dave..... i've seen (9V shaped) battery clips that hold 4 AAA(those are the smaller ones right?) batteries i think, and they're meant to fit into a compartment meant for a 9v, i duno maybe that would be something to look at, they might make something similar for 2 AA's then just use 2 of those, in the 9v battery boxes for guitars??? i know i have one of those thingy's around here i'll take a pic if i'm not making sense...

daveq Posted January 8, 2004 Report Share Posted January 8, 2004 I'm not sure I understand. Are you saying they would fit into the Gotoh 9V box? I have the AA holders that have a 9V type adapter for the wiring. It's the box/cover that I was looking for. Never found one suitable for a guitar.

daveq Posted January 8, 2004 Report Share Posted January 8, 2004 oh my GOD! i just bought 3000 blues for 10 bucks on ebay What type? What packaging - the T1 type? Are you talking about surface mount? Something doesn't sound right. I checked mouser and digikey - very similar pricing. Also similar to the other place I got mine (lunaraccents - I think? - I dunno). 3000 for $10 would be a bargain but I wonder if we are talking about the same product? Do you have pics? - or specs on them - what mcd rating? Quote Link to comment Share on other sites More sharing options...
Ava-Adore Posted January 8, 2004 Author Report Share Posted January 8, 2004 I think you need to spend some time with a breadboard and some components before making any plans. No kidding daveq, whoa... all plans are stopped for now. thanks everyone, almost jumped into a big mess. a little education on LED's and then maybe I'll start again.

Snork Posted January 8, 2004 Report Share Posted January 8, 2004 i have them they work fine. just regular 3mm leds. i cant remember the mgd's or whatever how bright they are is measured in. Quote Link to comment Share on other sites More sharing options...
daveq Posted January 8, 2004 Report Share Posted January 8, 2004 Snork - I just checked Ebay real quick. They do seem cheaper but not that much cheaper. I didn't see anything even close to the 3000 for $10 price. More like 25 for $5.00. Let me know if you still know of the supplier. Quote Link to comment Share on other sites More sharing options...
