Tremuls Lune LDR candidate

[chromesphere]

Hi All,

Does anyone know if this LDR would be ok to use for the Tremulus Lune?  I'm having difficult finding one out here in ozland:

http://www.jaycar.com.au/productView.asp?ID=RD3485&keywords=ldr&form=KEYWORD

The resistances seem ok...

not sure about the rise and fall time though..

If im reading the datasheet for the VTL5c2 correctly, it has a rise time of 3.5ms, this ones 50ms, and a fall time of 500ms, this ones 40ms.

Would i seriously even notice the difference (assuming those figures are important)?

Thanks for any help!!

Well, I can't answer your question, but I built two Tremulus and used random LDRs, and they both worked great.

Thanks Marcos,

I'm thinking im just going to give it a go and see.  It looks close enough.  Famous last words :-)

Futurlec has an LDR that fits the Trem Lune specs.

For the price of 2 Jaycar ones you could get about 12 of the others delivered.  Only catch is you just have to wait up to three weeks for them to turn up on your doorstep.

Cheers,

Hey! I just used this one in my tremulus lune, and it works like a charm:

LED/LDR combo. Just put the white dot where the neg. side of the LED goes. Easy as pie.

Hey thanks Custard!

Cant tell you why i've never bought from these guys before...4 dollars delivery, and their prices are pretty cheap too...

So i'm assuming the miniature 5k-500k is the one to go for?  Do you know what the rise and fall time is for these?  It says 'fast' but not anything specific.  I suppose, even if they are the same as the Jaycar ones, there 1/10th of the price!

  doesn't seem to be critical, but I don't have the NSL-32's Lune to compare fastest settings to.
  This one does plenty fast for me.
