Further update for anyone interested 🤣 I am in conversation with Xvive to have some produced - they hit will be big, but will it be worth it.

I grabbed them from Huayi, they came from china to uk pretty quick also. How do you you feel they would do in the Compulator with the off resistance being so high ?

And that’s my dilemma, is it ok ??? They fly up quick to the Megs

Is that a hint of sarcasm Mr Robert …. Or …. Do you believe in your expert knowledge its ok ?

Update - they have arrived - light resistance is anywhere from 200 - 400 ohm, as soon as you take the power out they are up to 20m ohm in seconds. Do we think they are ‘NOT’ in spec 👀

So I think it was me that started the thread, heavens knows where it’s gone the legends @Chuck D. Bones and @Feral Feline added all the important stuff. I have actually just done a layout for it, probably sending it off for fab next week.

Just ordered a bunch of 10s, lets see what turns up - will probably be ext year !!!

Thanks man, really appreciate you chiming in !

So these are all over the eBay and Ali but the xvive ones don’t look like that at all ! Have you ever tested them ???

It’s for the Demeter Compulator. Where are you seeing them for $5 ??? I literally can’t find any ‘genuine’ ones anywhere.

So I know that this has previously been kicked about, but these things are all but gone I think. There is a seller in the UK but they want £20 each for them. Has anyone found a suitable alternative, opto coupler or LED and LDR combo. Thanks in advance.

Well - mine officially blow - I would love to say I have been educated but it’s all PHD to my primitive brain - thanks so much all !!!

Thanks dude - I was really confused as to why there like be a mix of that, and a few grounds kicking about. Iv knocked up a PCB layout for it. I would normally flood both sides for ground, but I have done one side ground and the other V.Bias. Every day really is a learning day.

So looking at this schematic I am confused with the whole V.Bias thing. I am likely wrong, but I would normally see ground where they are on this schematic. Do they just all link together through pin 6 and 7 of IC1 ? It’s got me all twisted as it’s not what a schematic would normally look...

Thankfully I always socket ICs. Popped 3 and 5 out and bridged them. The Ic is right under the gain pot so it a short hop to Vref. Not has chance to test but will report back tomorrow. Thanks again brother.

Ahhhhhhhh feck, thanks dude - now to hack the pcb 😩

Thanks man, also thanks for your awesome Eagle package - it’s helping learn layouts sooo much, bloody legend.

Thanks for digging that out man - looking at the schematic if I start with changing teh resistors in the power section to 10k and the resistor between pin 1 and 2 of Ic2a too 100k !!!

Hey all, so I have done a Klon board minus the charge pump. Used a pretty standard schematic. Just knocked one up and am getting zero sound at pin 1 of ic2, before all is fine. I have checked, checked and double checked all components etc, reflowed too - I am perplexed. Something tells me maybe...

Now I get it 🤣🤣🤣
