already posted in tutorials section, but figured nobody would see my post
so i got my "modified" 6 ch usb soundcard from midwest lasers and plug it in to find my scanners are still putting out jibberish when i can get it to drive the scanners at all. the test pattern (the only recognizable image i could get it to project) in spaghetti (lfi was totally unresponsive) has blanked areas that travel all around the design? now i find that i need another component called the "correction amp". ok... i kin find 1 of those eventually.
but im going through the steps outlined in 1st post and opening the .wav file provided in the link just to confirm all 6 channels work using headphones to listen for a sound(groovy trak btw, a real toe tapper) : front L and front R ok- white noise, volume of both channels change appropriately when i move volume slider, but rear R and rear L behave unexpectedly as i move the volume slider in media player to max. the sound goes from one channel to the next and fades completely out when the slider reaches max volume.(the only way to get full volume on both channels is to park it precisely in the middle)and the same with the jack for center and bass. is this normal or is there something seriously wrong with the mods or the soundcard itself? the only mod i can see that was done to the soundcard would be some new caps next to the output jacks, where im gathering i would connect the leads to the correction amp.
oh yeah 15kpps scanners if that matters.
HHHEEEELLLLPP! i got 12 days to figure this out.(we got a memorial day gig that , properly executed , will allow us to fire the boss/owner of our outfit) the best tech support i could get from the seller was to "just play with it and figure it out" for myself.
thanx

been doing my research, got the 2007 revision for variance filled out, my projector should be assembled by the time we get it back. applied for slightly higher power than i expect to actually be running by then , but just how else would yer propose plans for a constantly evolving beast?
ok so i have edited once already as my reading was very productive tonight, witch leads me to better questions, its prolly a good time also to share wot i have to work with at this point: i have a red dpss(?) the beam looks like a tem 30 on the transverse mode chart i found, and another red diode slightly higher wavelength but in a tiny housing and 2 adjustable lens that im guessing are the collimator. after removing the first of the 2 lenses the beam went from nice-n-round to a narrow stripe(found a thread here describing this very thing saying these r bad)beside the fact that the diode seemed to strobe at @40-60 hz and i believe i killed it trying to push the wrong voltage and current through it trying to figure why it was flashing so.(strobing still- so it was not the power and likely crap to start with) but i believe the driver/power supply looks like its all on 1 board and is potentially still useful(can post pix as soon as i learn how).now the dpss(allegedly, i havent taken it apart yet, but ist packaged like the dpss green yag)as i said resembles the traverse mode diagram labeled TEM 30 can this be made nice-n-round like the other with those 2 lenses? and when folks speak of a multimode laser do you mean it can go back and forth between TEM 10, TEM 33, TEM 31 etc. or is it referring to anything other than a single spot TEM 00?
now we also have an argon ion tube putting out @.25 watt(when we replace the power supply, will ask for leads at another time)but im not sure we can incorporate this into an rgb as the "blanking" method would be drastically different?
i have also just purchased an external usb soundcard with 6 channel out that im using to control a set of 15k scanners and blanking.(thanx 2 steve @mid-west) still using freeware, spaghetti,laserboy,lfi player. got a test pattern in spagh. but the areas where the laser is "off" seem to wander around the image??? as of this minute its still giving me fits, but im sure there is another place on the forum where i can beg for someone to walk me through that mess.
thanx so much for all the help,
