Soft circuit trouble? Answered
I am having trouble with a project that I am working on. I have 12 leds in parallel spiraling out from a centre connected by conductive thread, the Led's are yellow and where stripped from a battery powered led xmas light set. I intend to use the battery holder and on/off switch unit that came with it (2X1.5v batteries and has a 6.8ohm resister) to power the lights. Unfortunately when I connect the power supply to the lights the first led is bright and it each led following is progressively less bright, the leds at the end are pretty dim.
So this is basically the same circuit that the xmas lights had but with conductive thread instead of wire. I double checked that there were no loose or crossed threads. After discovering the problem I checked the details about the conductive thread and it has a resistance of 30ohms/foot. The length of the thread connecting all of the leds is roughly 1ft.
So I'm guessing the problem is that there is too much resistance in the circuit? Or is there something else I'm doing wrong?
Is there any way that I can change this circuit so that it can still run on 3v batteries (2x1.5v)?
