there are quite a few unusual components

Looking over the BOM all the parts look pretty common except those 8-way switches.

I am not sure you would save much money this way.

For me it's not really about the total cost but having $350 to drop all at once. Real-life stuff sucks up most of my cash but If I can buy parts here and there I can eventually get it built.

Anyway I will try to save up for one of these kits b/c they look awesome!

Hi, thanks for the kit, nice build.

Have received the update firmware email. I don’t have a computer, is there a way to update the firmware with an iPad or android tablet?

Thanks

Hello

Glad the build went ok.

The firmware updates are via MIDI Sysex, so if you ipad or tablet are capable
of sending MIDI sysec then it should be ok.

Sounds great!

Are the pots/jacks a special/rare kind?

Hello

Pots are 9mm snap in type, jacks are Thonk mono and stereo.
So not very rare, but its hard for me to guarantee working builds with user supplied components.

Hi Ryk,

Hope your doing well, thanks for all the recent updates.
Just wondering whats happening regarding the built Roland 100M format modules, any idea when they will be available?
I hope they are not on a first come, first served basis as im horrible at missing out due to not seeing when things become available.
Also any idea what the price will be?

Cheers, Rob

Hello

The Roland 100m version is in progress.
Currently waiting for panel prototypes, which is quite
slow process marching paint and surface texture.
The panels are bead-blasted to create a similar texture
to the original 100m panels, before painting.

I haven’t worked out the price yet, but it will be quite a bit more
than the Euro modules. Mainly due to the panel costs, and also the
rare and expensive knobs.

Hi Ryk,

after just finishing building it seems to work fine for just a few seconds, then it looks as if it crashes (LEDs disappear or some become static).
I presume I've probably got a short somewhere on the 5V line as the through hole regulator gets rather warm in that short time frame.

I'd appreciate if you've got any other ideas other than tripple checking all joints and removing any flux remains.
