EDIT: See you replied via email, thanks.
Hey there Scum,
Did you get my message re the Sensor? Also would like to know when it was last calibrated.. I believe the readings drift off after a while.
All the best :thanks:
I get why you would think it works like that, but spinning actual lasers is a much more costly way of shooting lasers on to a spinning mirror.
Glue a mirror on to an old PC fan or motor and shine the laser at the mirror from close USING EYE PROTECTION. Smoke a cigarette in the room...
Can anyone comment on the reflective efficiency of the thicker mirrors supplied with the optics set with 635nm at 45deg (as one would see in a knife-edge setup). When I turn it toward that direction it seems to reflect more yellow/green than red.
Would I be better to go with the fs...
I built a soundcard DAC about a year ago and I must have spent over 50 hours total assembling, tweaking, re-tweaking, re-installing drivers. The newfound freshness quickly evaporated and I realised how worthwhile buying a DAC would be (even if it is iShow).
Anyway I am here to help not convince...
Thanks for your review. I just tried out QS and to be honest I found it quite limited for making laser shows. (Please no one judge me!)
I am skeptical of getting a demo version of LSX from Dr Lava, right now I can't even register on his forum. Fingers crossed.
1) Does LSX offer...
My signal is NOT selected to be inverted in LFI so when I unplug the card, everything pops to max.
As far as I am aware the two options each have their drawback:
Non-inverted: Safe as long as the usb card stays connected
Inverted: No sofware crash protection, but safe against mechanical...
My problem: Hotplugging the soundcard pushes all channels to max output
The goal: To run a safe show
I have tried so far:
a) Relay linked to +12v and the usb 5v line ---> sucks power from USB making card useless
b) Solenoid to +5v usb ---> too delayed
c) Using usb 5v to power the correction amp...
Hey Rob. I loved the obelisk.
Do you remember when I came to say hi? I was the young blond guy.
I would love to be involved in some sort of laser project next year for AB if you're interested. I just finished my own 1W RGB 30k scanner unit, analog controlled.
Where did you get your lumina...
Cool idea James, thanks! What's the story with that avatar? Its my favourite!!!
I feel rather honoured that I received one of your 39 posts here on LPF. :wave: yay Love your software and I have been reading tons on the laserboy forum.
Have come a long way. Long way to go. ANYWAY!
Thank you so much for your reply and helping me out.
#1) Which alternative IC? Would the TL082 give the improved voltage or is the TL072 fine?
#2) So there is a positive and negative signal coming from one single connection which is fine BUT the galvo driver connection is as follows:
A friend of mine says although this style correction amp uses -12v, it does not incorporate -12v (or is it -5v?) into the output, meaning your scanners will only get a positive voltage, limiting your scan angle.
Is he correct?
I can post the schematic but I assume someone will know this off...
