Thank you!

You know how a switch works, right? Now look at the jack and see what the little bits of metal do when you plug something into it. Got it? Now ignore the ground wire. What's left is two wires and a switch. Bingo.

Fellow banana fracers,

just wondering if anyone has converted Blacets Micro LFO to nanners

& would lend me the wisdom of yr experi-ances with regards to dealing with these pesky board mounted sockets hmmm.....

I have two ideas; first is expand the holes of the sockets towards the edge of the panel - drawback being an odd shaped hole & possibly a gap that will need a washer behind the banana.

2nd idea; (leaning in this direction at the moment) expand the size of the pot holes so that they & the board can be scooched over to the right, freeing up enough room on the left - drawback is misalignment between the knob & the ring of dots, but, this might make some room on the left for a switch to replace the normal in the Rate CV socket...

Plan to use a pull-up resistor on the Gate input, much like BananaPlug has described for the BZ Gate(Rst) input, hopefully that will work here.

Part of me is hoping that once I get the socket holes drilled out I'll get lucky & the bananas will just fit in... somehow I doubt it cry

Well, after playing around & taking a closer look I realized the best way to do it will be to remove the pots & LED from the board & mount the PCB on stand-offs, little trickier, but will be alot neater than hacking the panel.

They said it couldn't be done.... no wait, they said it probably shouldn't be done... wait, whose 'they' ... what?

that looks tricky DGTom nanners

, did the pull-up resistor work?

Yeah, exactally the same set-up on the Micros Gate In as on the Binary Zones Gate(Rst) - so after I got the latter to work as per BananaPlugs posts I did the same thing on the Micro, 220K from the socket to the switch pad on the PCB. The panel switch selects between the internal pulse or the socket for the Rate CV, which is awesome! Kinda thinking of putting a Centre Off in there so you can toggle between skewed waveshape / normal / CV'd without touching the pot.

I'm buzzing now the headache has worn off, that was easily the hardest one of the lot, the last few modules should be a breeze.

Love your blog Charlie, gave me an idea for converting the Quad Mix VCA - bring the internal Bias Voltage out to a socket = Global Volume control / multi-purpose CV source SlayerBadger!

Almost run of of nanners now! Gotta email Bugs grin

So as posted elsewhere, I bananafied all of my Frac modules except my two Wiards. I'm leaving the Borg alone, because I still might sell it, depending on how I feel about the 292c clones I'm building. The Noise Ring just kind of scares me – I definitely need to talk to someone who's done this (Tom Bugs was suggested in another thread).

Binary Zone and Quad VCA are half finished because I don't have any switches here at the moment, nor 220K resistors. I also somehow killed the 4204 on the BZ. So I have a Mouser order to place tomorrow.

N00b questions:

Switch terminology still confuses me – what kind of switch should I be looking for?

The 220K "pullup" resistor is just a standard 220K resistor, right? "Pullup" is just describing what it's doing?

And finally a pic:

I also have some "in progress" pics here: http://twitpic.com/photos/parasitk

Thanks for the info and pic! You wouldn't happen to have a pic of the back of the module would you? oops

Bugs, when replacing normals like Ext Rate with switches I connect the jack to one side of a spdt switch, the wire feeding the circuit to the middle and the alternate source to the other side. That way when Ext Rate is switched to use the signal from Aux out, it's also disconnected from the jack so you don't have the possible problem of shorting two outputs together.

Maybe your tiny switches are spst though.

My Binary Zone is fixed! Thanks to BananaPlug and DGTom for all the tips and help.

I punched a new hole for the switch, and left the jack where it was. I replaced the 4024 chip and all functions as expected. Did the pullup resistor thing, but I haven't tested it yet. I never really use that jack anyway oops

Next to finish: The QuadVCA and tackle that Noise Ring!
