Watch out! I just nuked 1-post user "gear101" after receiving five different complaints over the course of about 20mins that he's sending PMs to people offering to sell gear. Seems pretty fishy! I'm sure he'll be back under a different name but with the same old game. Be careful! Thanks to everyone who let me know about this guy.

Hello,

These are finally ready for production. A brief description for those that haven't been following in the other thread:

This board is a simple externally clocked, 8 Step flipflop/counter based sequencer that can count upward, downward, and pingpong. The CV output range is 0-10V. The clock input has a comparator to make clocking a bit more flexible, and there is a Gate output that outputs a 10V gate pulse. There are connections for 8 pots, 8 LEDs, Mode Switch and the CV/CLK/Gate IO jacks. The board is approximately 3"x3.5". It can be clocked into low audio range.

Boards are $20 each, which includes shipping in the US. Outside the US, please add $5 Per Order (not per board.) Please reference "FlopSeq" in the Paypal subject (as there are other boards open for orders right now.)

Paypal address is:

Thanks for the interest in this project!

Note: You can combine your orders for all three of the currently available boards if you like. I'm also going to leave the 258J orders open, and close them all at once.

Very tempting...

Is there a schematic you could share please?
I'd like to make sure I understand all of the sequencer's functions before I decide.

You mention connections for a CV pot and LED per step, but I can't tell if there is a Gate/Trigger switch per step too... I guess so if there is a Gate output, correct?

Is the Gate output the same pulse width as the Clock signal?

Cheers!

There is not a gate switch per step. Just a single gate output, with one pulse per step. I can plot the pulse-width tonight.

As long as all of the boards for the order are referenced, one order should be fine. I was trying to keep these separate early on, but it makes more sense to combine them at this point if desired.

Thanks!

Hi,

Could one do something cunning with the LED outputs to make individual gate outputs? Is there any break in these between steps?

TTFN,

Ben

I'm feeling sort of dense here, but it's not actually clear to me whether the number of steps is adjustable. The list of controls and I/O doesn't seem to refer to a reset or control for number of steps. 8 steps all the time? Did I miss something obvious (wouldn't be the first time!)?

No, no step count select. This was originally intended as a simple sequencer just for my Easel panel. Then some people expressed an interest in it. I'm working on a complex sequencer that will have step count, gate off/tie, division, 8 or 16 step versions, etc. But this will not be available for quite some time.

I'm uploading videos now, (not great quality, but...)
