Feature wise it has a blur amount & extra gain compensation potmeter,
CV over dry / wet (crossfader from dry signal to blurred result)
filter range switch
input & output jack.
A nice and simple DIY project
The BLUR module can be used as standalone video effect
At extreme blur settings you lose sync (this can be adjusted with a smaller capacitor value at c8)
The gain setting is too high, this should be adjusted with other resistor values at r18 & r28
The CV input will also be unsynced, so it will scroll.
If you use the same source and add some variations to it, you can get nice results.
image changing effects such as keying & highpass filters / edge enhancers work really good:
the results are partially blurred effects and shifted patterns.
I’ll post some screengrabs later!
