Dang! Missed this one!

Could you put me down on a unclaimed order list or down on the next run if there is one?

cheers

Hello

I have received the boards, and testing seems ok.

When I am done burning 100 PIC Micros [phew]
I will PM everyone who reserved the boards
with payment details.

thanks

So amazing that all that functionality fits on such a small PCB!

hey ryk
looking forward to this
i have a couple of questions

what are the panel controls exactly?
i have tried to look at your photos but can't zoom in enough
i'm trying to work out my panel now and have to consider why kind of rotary switches im going to get.

also since i have reserved 2, is there there be a way to chain them?

Hi Ryk,

I want one if you have any cancellations please. Thanks!

djthomaswhite at hotmail Very Happy

I'd also be in for two of these if a 2nd run happens. Looks very nice.

Thanks, Ian

I missed this one Sad

If you do a second run I would like 1 pcb. If someone cancels their order I would be happy to buy their pcb.

i'd love to be on the list for 2 PCBs (with PICs).

so, to echo the sentiments above...

if someone cancels, or a 2nd run is done, please count me in!

and, really great work.

Hello

Thanks for the interest, if any body drops
out then I will contact people on the waiting list.

that is a lot of rotary switches!

perhaps a group-buy is in order to get some NKK miniture rotary switches for cheap.

Its planned that i draw a PCB for those switches( like the alphas) , so one can wire those with Ribboncable as used for Euro Powerconnections.
but it will then need some more space . ( MTA.100 connectors will fit too )

To get them etched for myself will take some time as i must hope that a friend has the Time.
So it will be untested maybe
you would need those switches in the printmount version. Maybe keep that in mind

I really like those NKK switches, what are we looking at pricewise?

Hello

Tim Servo · Posted: Wed Aug 20, 2008 4:55 pm Post subject: New sequencer project

Note that you can also use a pot to select the number of repeats per stage, as the input on the micro is actually an A/D input. You don't get the distinct 'steps' you do with a switch, but it certainly simplifies the wiring (you don't need the switch and the resistor voltage dividers anymore). the truly adventurous might even want to add an external CV input for modulating this. :-0

Tim (doesn't have distinct 'steps' either) Servo

Hello.

Yes, Tim is correct the switches can be replaced by 50k pots, like
the Max Stages option at the top of the drawing.

Please note tho, the resistors on the "stage" switches are only for the first
switch, the rest are all wired in parallel with this first switch.
I hope this makes sense.

I'm not able for now to draw something.
I must first see the Board to understand i'm fear,
and i any way think for now that i gonna build with Pots then.
It really seems to be much simpler to build with pots, AND spacesaving
