Does anyone know what kind of chip could substitute as a replacement for this part??
I want to find something to replace that optoisolator that's cheap...I could make the one's posted as general guitar gadgets, but photocells aren't cheap.....
Any suggestions??
If you on smallbear they have a few different ones. I don't remember how much, so I don't know if they are in your price range or not. Other than that I just use the clm600's, I have some left over from when they were in production and got them cheap.
Matt.
NSL32 and VTL5C3 are good replacements.
DIY optoisolator is just as good as most commercial one.
so if i make the diy clm6000, what type of photocell should i use??
Also, where can I find them cheap???
I've had good results with the DIY CLM6000 per RG Keen's instructions on geofex. Radio Shack sells cadmium sulfide LDRs and at least one of them in the five pack goes in that wide of a resistance range <1000ohms->1meg. If using more than one in a given circuit-For best results, match them as closely as possible. It's definitely cheaper than the CLM6000, too.
I usually use Silonex NSL-19M51 or Vactec VT935G.
R.G. recomended some LDR's from Mouser in Neutron article
and L934SGC 3mm green super bright LED's .
I use L53SGC and they have same characteristics as L934SGC, but in 5mm format.
You MUST use green LED's because LDR's of that
type are most sensitive in green wavelength area ( around 560nm).
