[WIP] Blur/Sharpen

A new project I’m working on: a blur and sharpen module.

Features
blur input jack
blur amount potmeter
switch for white/black fade
switch for range (H/V)
CV input for dry/wet
Blur output jack

sharpen input jack (normalised to blur input)
sharpen amount potmeter (mix)
switch for range
Sharpen output jack

Blur + sharpen mix output jack
optional: dry output jack, potmeter for dry/wet, potmeter for gain

Progress:
Blur with dry/wet crossfader is working on breadboard, needs some gain finetuning
Sharpen concept is working, next is breadboard testing.

I think I’ll separate the Blur & sharpen projects, to keep it simple
the BLUR is now 4HP

Sounds like an excellent project yet again, looking forward to building it!

pcb and panel are ready for jlcpcb. proto1

the pot parameters are:
blur amount
additional gain

switch:
range

jacks:
input
cv (crossfade dry wet)
output

Would be curious to see your schematic if you’re open to sharing. We definitely need more filter modules out there so this is great to see!

I’ll post it when it is done and tested .
it is a combination of a lt1251 crossfader and a RC lowpass filter with added gain.
fun and simple, and very useful in my opinion!

it might change a bit when tested in a modular patching enviroment
(instead of the "is it working?’ breadboard land it is in right now)

The Sharpen module will be something like this:
pot controls:
edge mix
dry mix
edge gain

switch:
edge width

jacks:
in
out

the prototype in in and it mostly works :slight_smile:

I’m getting really cool results already, but it needs some finetuning (pot direction, normalized voltage on the CV input and some minor panel details)

preview with some other blurred new modules

“I am BLUR!”

Yes! so pumped to see this moving forward congrats.

also a futurama reference is always appreciated

and just gonna say the blurred out other new modules are very exciting!

Is the blur in the first photo (the one with the blurred modules) done with the module?

that would be cool, but no. (it is a photoshop radial blur filter)
however, I’ll post some clips later. Yesterday I got pretty nice fade/smear blurs out of it!

Definitely looking forward to this blur module!

check it out at super booth next week!

Nice work ! waiting for the release. Looks afordable and powerful :slight_smile:

Yeah I’m gonna need three of these. Awesome

Why CV on wet/dry mix instead of filter frequency? Keeping it simple? Animating blur amount would be epic, I would pay more for that.
