FV-1 Multi effect full forum project ready to go. (ShimmerVerb Also)

Hey Mick,
I'm trying to assemble your circuit; I've just a question: can I use 1uF 100v instead of 16v? I've tons of Elna's...  

Bye.

Yeah you can use the 100v caps, as mentioned just watch out for the physical size, may need to lay them lay them flat if possible under the pots.

Finally I think your board is the best option,
but I will go developing my own board using ATmel family... where I'm alreaky skilled.

That sounds good, I look forward to see which direction you take with the Atmel route. I quite fancy the idea of incorporating an LCD with and the ability to name and store pre-sets.
Ians babelfish pedal has a LCD which is a few replies up in this thread.

Clipping signal with diodes is the easier solution. And for sure choice 1, but If I can built a small peak indicator (small in term of components used and easy) I'll put my choise on an input attenuator (like a voltage divider or like that..) In this way the input signal could arrive to FV1 as is with no additional clip.


LCD is cheap and very good choice.. but for my learning curve on FV1, it will take place on wave 2 :-)


My priorities are :
1) Respect of analog input signal : No additional clip, and No A/D D/A for the DRY
2) FX signal out of FV1 should has an analogic feeling as much as possible
3) 1590BB enclosure max size

Thanks again guys for your contribution ( I hope in a near future to start a tread with the result ! )

Just incase this is of any use to anyone.....


I also have the proteus design files if anyone wants them, ill be happy to pass them on.

Havent even started the coding yet

Well, i will use http://www.musikding.de/Box-Type-BB to include an Arduino board inside, so...I think I haven't any problem under the pots.
Bye.

I want it if possible 

Why not using Arduino nano?

[Mbas974]

...sorry for the OT.

what is the library in eagly to get FV1 device (it should be SOJ28X) but I can't find any..
Thanks in advance.

[tacromx]

the files are here....

Hey guys,
I have now just two simple mono jack for input/output connection.
How can I connect them to circuit to quickly test it?
Can you provide me a picture of connections on PCB?

Thanks,
dkmorb.

This picture should help you with off board mono jack connections.


Remember that the stereo jack on the input is used to switch battery power when a jack is inserted so with a mono jack socket place a link where there is a thick black line drawn.

Hey Mick...it works great!!! Now it's time to connect to usb ;-)

That's great Pasquale, I'm glad you got it up and running. I look forward to seeing your results on the usb.

Hey Mick,
USB works quite well (by arduino) and SpinCADBuilder!

Just anoter question: where can I drill three holes on pcb (copper free :-P )?

[dkmorb]

@tacromx, @Mbas974, @iami
Why not implementing a common solution based on small arduino (nano, mini,...)?
Do you really need to build your control hardware?
BTW,
I quickly checked iami's code -> nice way to swindle old fv-1 dsp!!! Think about a 25LC1024 SPI instead of internal memory... 
I quickly checked tacromx's design -> good idea to make "one big board"!!!

[tacromx]

 

i think you may need more I/O ports than a Nano or Mini has, use I/O expander maybe it will work.

I thought I would post this as a demo for the forum project, the two pedals played here are exactly the same as the forum FV-1 circuit and with the same software installed but they are the pedals I sell on my site so ignore the pedal names etc.
Adam has made a great demo of the sounds available and the full intro tune is built up using just the FV-1 pedals, so just as an example of the sounds that the FV-1 project is about here is the youtube vid. All the software is available and in the thread for DIY use.

That was excellent. That guys playing was perfect for those kind of sounds. Great sounding pedals!

[Mbas974]

dkmorb I'm available for a common solution (programming arduino or desiging in eagle as well)
but I won't coordinate the project....  and better start a new dedicated tread if you want starting this.

Sorry, I missed this post, I will upload the files of the pcb and you can check for yourself for where you can drill some holes, the files will open directly in diptrace for viewing and editing. I will see if I can do this in about an hour.tonight and they

[Ice-9]

Here are two pictures of the pcb. The first pic has the copper pour top and bottom in view and the second picture has the copper pours removed.





I have uploaded the diptrace files which can be used for editing and also make it easier to see what's going on. two files in the rar and again one has the copper pours removed.

Download the free diptrace to view/edit rar file
