Hi. good job. How many led can you use? is that the maximum?

[uberscientist]

@magorwilly1 The datasheet for the LM3915 has information on adding more LEDs. A quick google.com search should be able to help you find it "lm3915 datasheet"

damn cuz mine is exactly like the schematics and it doest work...

[uberscientist]

@xtigoxxx email me pics of your circuit if you can here: uberscientist@gmail.com

I'll try and help

[xtigoxxx]

are you sure you did that acording to the schematics ?

[uberscientist]

@xtigoxxx

I'm not sure!

I think so, but I am not sure, maybe I tweeked something here or there... it's bread boarded in the video, I believe the one built as the schematic may be less sensitive than the one in the video, since it was designed to be attached to a bike wheel.
