I have a blu-ray laser pointer made by a member here. The output of the laser seems real low compared to a PHR blu-ray I have running 160ma. I check the ma on the blu-ray made by the member and it is only 61ma. That explains the low output, LOL.
I unscrew the business end (an easy host to work on I might say) and attempt to adjust the output on the rkstar micro-drive with my Fluke meter in series with the negative pin off the diode. I can only get a range of 55ma-83ma. This is supposed to be a full range rkstar driver so something is wrong.
I am using two brand new lithium 3.0 volt CR123's in my host. That's 6.26 volts at the rkstar driver. That should be enough correct? or do I NEED two 3.6 volt CR123's to properly operate the rkstar micro-drive? I read somewhere that blu-rays with the micro-drive need 7.0-7.2 volts.
I checked rkcstr's webpage and the micro-drive full range should have a series resister (R1) marked 2R7. The rkstar driver I have has the series resister (R2) marked 4R7. I do not have a parallel resister on the R2 position of the driver board which I read is only for the pot range of adjustment, not max output.
