FFG

FFG stands for Falsch Farben Generator, literally, fake color generator, the original name of the circuit when it was published in german magazine Funkschau in 1987, realised by M. Klose and H. Neumayr.

The project have been resurrected recently as “Visualist” by Berto A and the documentation have been translated and publish on Makezine. The original doc (in german and in italian),  Berto A documentation and gerber files for the original board are available here.

The FFG is based on the original circuit and adds some modifications, mainly video rates CV control over each parameter (R, G and B level and comparators threshold) and NTSC/PAL compatibility.

The project will be soon available as a built unitDIY kits and circuit boards.

Happy to announce that preorder for FFG (aka #falschfarbengenerator) are open, available as a built unit or a DIY kit (pcbs alone will follow). First units/kit are expected to ship beginning of December. (Link to the project in bio)  FFG is a video colorizer based on a circuit from 1987, published in the German magazine Funkschau, project recently unearthed by Berto A under the name « Visualist ». (Original documentation and (yet untested) gerbers of the original board are available on github). FFG addresses a few issues from the original circuit while also enabling external modulation of each parameters, meaning it can be controlled using external signals such as audio or CV from a modular synth, from slow LFO/enveloppe up to video rate oscillator.
Another improvement over the original design is PAL/NTSC compatibility, using an internal switch to set the standard.  The device works by affecting colors (Red, Green, Blue, Magenta, Yellow, Cyan, Black and White) depending on the brightness level of the input signal. This affectation can be modified using the bitswap and invert switches, giving up to 32 color arrangement. 
Shout out to Iker for the enclosure design, @loobabalooba for the enclosure graphics, Berto A for resurrecting the project and providing English documentation, @videocircuits for documenting his Visualist build, M. Klose and H. Neumayr for designing the original circuit, and of course to everyone who supported me during the development of the project 🙏 🙏 🙏

Extract of the music video I did for @thedutyfreedom - Chronic Durations (check their bio for full video)  Mostly FFG and AVE MOD/CBV001(S) used here, shot on a CRT TV  #thedutyfreedom #chronicdurations

Quick test before shipping this FFG, with signals coming from an audio synth as modulations.

Okay, so this is how synced modulation looks like on FFG last revision. 
Quite happy with it so far, need some more tweaking on the CV inputs, so they’re 1V compatible to match levels coming from an LZX system. Each inputs have an attenuator, so standard 5V signals can be tamed a bit. *Two LZX Castle VCO modulating low and high threshold of FFG comparators, FM on the oscillator synced to hsync.* #videoart #analogvideo #ffg #falschfarbengenerator #lzxcastle #diy #syntonie #thispersondoesnotexist

FFG build documentation is almost done, still have to write the user documentation while I'm waiting for the final enclosure design. Should be able to ship a few kits to beta builders next week, will open preorder for built units soon.
