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.

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

Pre-orders for CBV001 modules and standalone units are now open! 
Expected shipping date: early February for modules, end of February for standalone units.  Footage processed in NTSC, stabilized using Stable and captured with BM Analog to SDI + Video Assist.  #videoart #analogglitch #analogvideo #cbv001 #stable #eurorack #syntonie
Quick test before shipping this FFG, with signals coming from an audio synth as modulations.

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 🙏 🙏 🙏

Entrée is now available!  Entrée (pronounced [ɑ̃.tʁe], french for input) is a Component to RGB colorspace converter and Luma Processor with the following features:  - Decodes SD/HD Component (YPbPr) to 1V RGBY outputs.
- Y signal is normalized to the processor input which features an attenuverter (contrast) and offset (brightness), plugging a jack in the processor input will break the normalization to allow the processing of another signal.
- Y pass-through RCA at the rear of the module to sync the sync generator/encoder to the external video signal.  It is an update of VU003B with a couple improvements:  - Low noise power supply
- Active attenuverter in the processor part
- 75R output impedance on the 1V output jacks to increase the bandwidth, resulting in a sharper picture in HD formats.  Some of those improvements can be applied to VU003B (both DIY and production versions), the details of those modifications can be found on Syntonie GitHub.
Get in touch by email if you’d like to have your VU003B modified.  The module is powered through standard Eurorack connector or DC barrel.  Inputs:  0-700mV Y, Pb, Pr, 75ohm
0-1V Processor In, 100kohm  Outputs:  0-1V R, G, B, Y, Processor Out, 75 ohm
0-700mV Sync Out (rear), 75 ohm  Specs:  - 8HP
- 90mA +12V
- 0mA -12V
- 0mA +5V
- 45mm deep  #eurorack #videosynthesis #analogvideo #syntonieentree #syntonie
