Enigma-E support
This page is primarily intended to give support to people who have built the Enigma-E kit. Any errata, omissions and additions to the manual can be found here. In addition we provide information to enhance your Enigma-E kit. If you've extended or modified your Enigma-E or if you've built your own case, please share this information with us, by dropping us an e-mail.

If you encounter any problems with your kit, please check our list of frequently asked questions first. Also check whether your problem is caused by a known bug in the software. You may also want to consult the Enigma-E user community (see below). If all else fails, drop us an e-mail.

 Known bugs

User community
One of the first buyers of an Enigma-E Building Kit, Martin Beekhuis, was so exited about the project that he has setup a Yahoo User Group to allow users to share their experiences and talk about the Enigma subject. The Enigma-E developers are also present on the group to anwer any questions you might have.

Build your own case
The Enigma-E comes as a plain PCB on which you build the components. If you want it look more like a 'real' Enigma, you would probably want to build your own case around it.

Some people won't bother about building a case and use the Enigma-E just as it comes: as a bare PCB connected to a power supply. But wouldn't it be great to put it in wooden box, just like a real Enigma? Or perhaps in a plexiglass case, so that you can see the interior?

The Enigma-E manual comes with full drawings of a suitable wooden box, just like the one shown on the right, but you may also download the drawings below and start building your case now. We would really like to see pictures of your own creations.

Adding letters to the lamp board
On an original Enigma, the lamps are covered by a film showing all the letters of the alphabet A-Z in the German order: QWERTZ rather than the more common QWERTY order. When a key is pressed, a lamp behind the letter is lit, so that you can write down the result of your encoding.

On the Enigma-E, LEDs are used to simulate the lamps, and the letters are printed in white on the PCB. The LEDs are aligned in the same order as the keys on the keyboard: QWERTZ, just like on a real Enigma machine.

You can make the Enigma-E more realistic, by mounting a piece of transparent material (e.g. plexiglass) over the LEDs, holding a film with all the letters on it.

Initially, no lamp film was supplied with the Enigma-E, but later we added a piece of polyester film that could be mounted over the LEDs. From serial number 1000 onwards, a professionally made litho-film with the correct typeface is included with the kit. Just in case you don't have a suitable film, you may download the PDF file below and print it on a transparent or polyester sheet.

Generate your own Enigma Codebooks
During WWII the Germans used different Enigma settings for each day. For this purpose, secret codebooks were supplied that were to be protected at all cost. We've now got software that allows you to print your own Enigma codebooks, along with several special message forms, both in English and German. Empty message forms are now also available in the popular PDF format, so that you can print them for re-enactment pruposes.

Zur Beachtung!
Most original Enigma machines carried a warning placard on the inside of the top cover. This sheet contained some maintenance hints and tips and a table to convert letters into numbers and vice versa. If you are thinking of building a wooden case for your Enigma-E, you may want to have the original Zur Beachtung! sheet. Click the image to enlarge. If you want a better quality image, please read on. In the download section below, you'll find a PDF file containing a suitable design, which you can print on a self-adhesive sheet.

Some original Enigma machines were not supplied with the Zur Beachtung placard presented above. Such was the case for example with many of the M4 machines that carried a hand-typed note or, more commonly, a printed Merkblatt-M as shown here.
Wolfgang Abratis from Germany has recreated the original sheet which is available for download below. Personally, he replaced the M by E followed by the serial number of his Enigma-E.

Using the M3 emulation - Warning
Due to a small misfeature in the Enigma-E setup procedure, you may run into trouble when using the M3 emulation. When using the M3 emulation, it is still possible to change the setting for the 4th wheel (although there is no 4th wheel). Please note that you should leave the setting for the 4th wheel at A.

The reason for this is that the M3 and M4 machines are actually quite similar. An M3 with, say, UKW B is the same as an M4 with its UKW-B and 4th wheel Beta, but only if the 4th wheel is set to 'A'. This way the U-boats (using a 4 wheel Enigma M4) could still communicate with the Wetterdienst who were using a 3 wheel M3 Enigma.

Over time, some modifications to the Enigma-E have been developed, both by our customers and by ourselves. If you want to improve your Enigma-E, please check our modifications page. At present, the following modifications are described:

  • Using white LEDs on the lamp panel
  • Fitting a serial port to the Enigma-E
  • Battery charger
