Problem's Post 1

So... I keep running into problems with the electronic stuff. Every time I figure it out I think, 'Why didn't someone mention that?' Why isn't that on a list somewhere of what to watch out for or to be aware of when creating an electronic circuit/soft circuit really? Well, there probably is somewhere, on one of the various websites that deal with circuit's and the Lilly Pad, I haven't had the time to look. (Hahhaha time what's that?)

So, what I decided to do is start listing the problem's I've had and why I've had them. Start my own list and then I'll see if I can't find something later. If I can find it great if not well I have my own (though some of this is conjecture and not being a tech geek, will only go so far.) Still, I have only run into a very small number of techy people who seem to be able to converse on the subject of electronics in a way that makes sense, who can understand what I'm saying. Everyone else I feel like we're speaking different dialects of the same language and getting no where; curious that.

1. Adding extra stitching doesn't help your cause, it doesn't make better connections. The added stitching/conductive thread adds extra resistance to your circuit and can actually cause it not to work. So going back over everything to make it more conductive actually isn't a good thing. For example see: Attempted Glove Light Project
 
2. So apparently you don't need a resistor with the LilyPad LED's? I added one because I had six LED's and with the other ones I needed a resistor for about every five LED's. However, it didn't work. So I took the resistor out and now it works perfectly. So I went to the LED Calculator, to try and figure it out. Either I'm not understanding the spec's on SparkFun - LilyPad LED's, correctly or something, because according to the Calculator with what I put in there the 1.5 vol AAA, battery shouldn't even power the six LED's, let alone anything else. I guess I still need a dummy's guide to electronics. (Really the whole power source thing is confusing and I ask people to explain it and they don't want to. Though the general consensus is you shouldn't hook up a larger battery to the lilypad.)
 
2a. EDIT: The LilyPad LED's do have a built in resistor on them. You do NOT need to add a resistor to the circuit with those. I appropriated the image from SparkFun, because in this image you can see the resistor on the little board. (see the little black thing next to the LED light with the green/yellow'ish lines on it. According to another smart man I know, that is a resistor that has been placed on the board.) If you try and do something one way and then do it this way that is a GOOD thing to know.
Some of this stuff really comes across as being at cross purposes for me and not being easy. The LilyPad stuff almost tries to make it too easy without any good explanations. So that if you do one and try and do it the other way you run into a whole separate set of problems. Hahaha the Data sheet above for this LED light doesn't even explain it right, we had to do the math... anyway, yeah.

Issues, problems, uncertain questions that why I try and voice them come out all wrong. Either that or apparently I just don't speak tech. Never had this big of a problem communicating on something before. Anyway, enough rambling more work to do. *disappears*
