Re: Pull-down Resistor
Hey everyone, I finally pulled my eleksmana se board out of the laser to add the 1K pull-down resistor as Greg documented in his post referenced above.
Now if I purposely unplug the USB while the laser is powered, and re-plug it, I get 4 or 5 flashes of laser light instead of a constant beam. The flashes doesn't seem to burn anything in their path, so I don't know if this is a low power mode, or something else. I was expecting to get NO laser light instead of the full beam, so I guess this is an improvement, albeit a partial one?
Has anyone else seen that kind of result after bridging the two pins as shown in Greg's blog post?
