Doepfer Timeline

Doepfer Musikelektronik GmbH is a manufacturer of audio hardware based in Gräfeling, Germany, founded by Dieter Doepfer.The product range covers analog modular systems, MIDI controller, MIDI hardware sequencers, MIDI-to-CV/Gate/Sync Interfaces, MIDI master keyboards and special MIDI equipment. 

Dieter Doepfer began developing audio hardware with a Voltage Controlled Phaser (VCP) module for the Formant, a do-it-yourself-kit analog synthesizer from Elektor magazine in 1977. Several legendary modular synths followed while Doepfer also focused on the development of MIDI equipment during the 1980s.
In 1992, Doepfer Musikelektronik GmbH released the MIDI analog sequencer MAQ16/3 which was designed in cooperation with Kraftwerk. 
In the beginning, the company had direct sales and interested musicians would receive a demonstration by visiting other customers since the modular systems were deemed too difficult for typical music shop employees to demonstrate. 
Facing greater publicity, Doepfer shifted the distribution to specialized points of sales.

DIY Modular Case Ideas

There are many ways to house your (eurorack) modular synth, i wrote about the pre-manufactured options from Doepfer earlier, find that post HERE, but of course you can also try to build you own case.
There are many ways to make your own A-100/Eurorack case if you start out with just the basic rails and busboard, and you can make it as cheap or expensive as you can.

Check out a few ideas;
Wooden cabinets and side-panels are still very popular amongst (modular) synth enthusiasts.
These simple case standards for the pre-manufactured LC9 cases are very simple, and can be sooo useful Also check out the other great modular pictures on his site.
Matthew Goike (@Goiks) also has some nice wooden cabinets on display and for sale on his website:

...or do what Stretta did (or rather what his brother did), make a high-end wood/brushed aluminium cabinet with integrated LED-lights and some …

Doepfer A-150-8 Octal Manual/Voltage Controlled Programmable Switches Announced

Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.) Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:
Module A-150-8 contains eight manually/voltage controlled switches.  Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2).  The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. 
Two LEDs show which in / output is active (ie. which is connected to the common out / input).  In addition the LEDs are used for the programming of the module: For each unit the operating mode can be selected:  Toggle or Level controlled. In Toggl…

The Eurorack Standard

Many early synthesizer modules had modules with height in integer inches: 11" (e.g., Roland 100), 10" (e.g., Wavemakers), 9" (e.g., Aries), 8" (e.g., ARP 2500), 7" (e.g., Polyfusion, Buchla, Serge), 6" (e.g., Emu) and had widths in 1/4" inch multiples.
More recently it has become more popular to follow the standard 19" Rack unit systems like the 6U (Wiard), 5U (8.75" e.g., Moog, Modcan), and 4U (e.g., Serge).
Two rack 3U unit systems in particular are notable: the Frac Rack system (e.g., Paia) and the similar Eurorack system.

Manufacturers using the Eurorack format include DoepferAnalogue Systems, and Cwejman in Europe, and Plan B, Livewire, and Harvestman in the USA.

The Eurorack format uses modules of 128.5mm (slightly over 5") height.
Horizontal width is measured in "horizontal pitch", where 1 HP = 5mm (slightly less than 0.2"); most manufacturers use a horizontal unit definition of either 1U = 4HP, or 1U = 6HP.
