• New Project: Enigma Z30 Machine Simulator

  Arduino Enigma • 6 hours ago • 0 comments

  While waiting for parts, I have decided to design a new PCB  for the numbers only Enigma Z30 using only parts on hand:

• Boards almost ready for production. A big update.

  The board is almost ready for production, can you spot the hidden vias under the G key?

  Here is the bottom copper layer. @Benchoff, Is this the latest Fritzing autorouter or is it done by hand?

  More pictures and the description of how it was done are here:

• Beginning the design of the main board.

  Next, we will start designing the main board. The main components here are the Arduino Pro Mini and some 16 segment displays. 

  The display and the Mega are arranged in a board the same size as the plugboard. A lampfield and a keyboard are designed as well,

  A proper Enigma Machine SImulator needs a working plugboard. The Mega 2560 Pro Mini has enough pins. Let's see if a plugboard can be put together in Fritzing.

  This is a quick concept thrown together. The holes are custom size vias. The board ends up being around 138mm wide.

  An order is placed for 3.5mm Female Stereo Audio Jack Connector panel mount M631. 

  This design will use common 3.5mm audio cables, so an order is placed for

  6" 3.5mm Eurorack Modular Synth Patch CABLE - BLACK - 10 PACK
  

• The discovery of the Mega 2560 PRO MINI/ATmega2560-16AU

  This is the board that makes this project possible. It is a smaller version of the Arduino Mega 2560. It has a Fritzing model. A couple of these are ordered.
