Great news! Any chance of some sort of build doc? Or is it idiot-proof?

Pretty Idiot proof. That said, I'll put one together just in case.

That's good, thanks. I can be a kinda special idiot.

Cool, great news.

I don't know if anyone is building this in a non-Euro format, but since I have to add a MOTM-style power header anyway, I was gonna try to build a little piggyback board with female 0.1" and male MTA156. Then I can also include a gate-to-trigger converter, and add a panel switch to choose "track-and-hold" or "sample-and-hold."

We'll see if I am not too dumb to actually make it work Dead Banana

Another fun mod to do it with another switch, to switch the s/h cap in/out of circuit. the circuit then becomes a VC switch, audio passes when gate is high, doesnt when gate is low. (it'll do this as is, but when the gate goes low, the cap holds it at the last voltage) just an idea.

That there's an interesting idea... so switch between having the cap in place and shorting across it? I might do that too if I have the panel real estate - I really want to fit this in one Frac unit (about 8 HP).

The switch would just essentially "lift" one of the cap legs, not short across it. you might want to try this mod out before committing it to a panel, as im not exactly sure how much the switch and wiring would affect the droop of the "Hold" function.

I like it! thumbs up

Necro thread bump.

Does anybody have a BOM for this V2 LFO ?

It looks very different to the V1 BOM, and there are no component values on the PCB (see Mike's post above).

I'm sure Randy posted this question during the recent chaos period for Muff's, but the thread has completely vanished.
I've held off building this because of no BOM and no panel, but I've got the bits to make a bracket and panel, and hate the thing just sitting there doing nothing, especially when I need more S&H and Pink Noise...

Re-doing a BOM for this right now. My old computer 'crashed' (5 years old kids tend to help with the process) I will be posting a BOM for this within the next couple days.

thumbs up

I'm looking forward to being able to get going with this build.
Many thanks for the pending BOM thumbs up

Many thanks indeed Mike.
Very much appreciated.

i would like to get one PCB/Panel set, is it possible ?
woodster
PCB's were available via Mike, but Panels were a separate matter.
I'd love to get some proper panels for the Miss10 PCB's, but I'm going to attempt some ghetto homebrew ones...
Randy
Does anyone have a photo of a finished V2.0 LFO PCB?

Thanks

Randy

I'm also having trouble finding the LM4558. Will these do?

http://www.ebay.com/itm/dual-opamp-8p-5-5mhz-MC-4558N8-MC4558N8-/40066 2684218

I have a bunch of TL072, can I use those instead?

Thanks

Randy

Hey Randy,

Mike gives a Mouser reference for the RC4558P as a suitable part in the BOM.
I presume it's correct, I hope so, as I have 3 on order for this module hihi

http://uk.mouser.com/Search/ProductDetail.aspx?R=RC4558Pvirtualkey5950 0000virtualkey595-RC4558P

As requested, I've attached a picture of my build, showing where I am currently with the PCB, and the component stuffing.
I'm now just waiting on the Trimmers (VR1 & VR2), a J111 (Q3) and a 47pf Wima Cap (C3) -



Let me know if there's anything else I can help you with.
I'm always happy to try to help a fellow wiggler get a build successfully completed.
Randy
Thanks woodster. I hate to order three little ICs from Mouser, the delivery charge will be a bit nuts. Those are the only things I think I still need. I've been using a heavy-duty aluminum cookie sheet as a source of panel material, so making a panel is up next.

Randy
woodster
Cookie Panel FTW

Randy
Does anyone have a wiring diagram for this? I also need the pot values, and I'd like to know what the trimpots are for?

Did I miss something here?

Thanks

Randy
woodster
Hey Randy,

Pot Values are there in the BOM above, 100k for VR3 and 10k for VR4.
One of them is LFO Speed, the other is a Waveform Skew, which is which ?
I don't yet know, but thought it would be obvious enough once I get a panel made and get it all wired up.

Trimmers, I'm not 100% sure about the functions, but was going to suck it and see when the time came, maybe there is mention in the old V1 thread ?

For a wiring diagram, I plan to go off the old V1 sketch, as I imagine it's mostly the same, even though the V2 circuit is slightly different to the V1
Randy
I'm looking at the panel on ModularGrid, which also has pots for white and pink noise and S&H in. I could do without the attenuators for the noise and I'm not even sure why there would be a pot for S&H in. I'm also not sure where to hook up the Fast/Slow switch.

I suppose I could just do the two controls and get it over with but Mike put together a really handy diagram for the v2.0 VCF here http://www.flickr.com/photos/23140551@N08/7736689048/in/photostream/ and having something like that for the LFO would be great.
