Found some steampunk wire and used it for our Enigma: The black Cloth Covered wire is exactly what we needed to give the plugboard his period accurate look & feel.

This unit is almost ready to ship, missing only its leather handle & certificate of authenticity.

Busy Week-end!

Since the last post, we put a few coats of Polyurethane with light sanding between each coat. We also drilled a square USB hole to access the Arduino Mega USB port through the inside box, and affixed the German Merkplat label.

We tweaked the plugboard & added all 26 female Banana jacks and put a drop of Nail polish on every single nut to ensure there won’t be any movement.

Next, we will will stain & install the handle and make all 10 plugboard jumpers using steampunk type cloth covered period accurate wiring & male banana jumpers.

We expect to be completed with this hand-crafted commission and be able to ship it by the end of this week.

Started tonight the important process of staining, varnish, sanding, repeat, etc.

After that, we will be able to decorate the box with a period authentic look, adding a handle, label and plaques,

Our client requested a plug board so we are in the process of (re)designing this.

 We strive to always exceed our client(s) expectations:
They say that true craftsmanship is about the process of being intimately involved with the making of a product that is well-made, long-lasting, attractive and/or desirable. Another identifying factor of true craftsmen is their interest in the process of creating. The focus is on the product, the creative process, and how much we enjoy it.

The ironic part it that the brain of the product (the Electronics) takes only a few hours to create while the container, if done right, can take up to a week…

Stay tuned as we get closer to the finished product.

A touch of band sanding and manual sanding yielded us a super professional looking box. We are particularly proud of our “convertible” design: just like the Germans who could remove their Enigma M4 from its box to insert it in the proper cubby hole on the U-boat, we have created an inner box that can be extracted from the outer box if desired. Doing this will also reveal the USB port to the Duino. (40 hours).

Next is the important steps of staining, varnish, sanding, repeat, etc.

For this client, we selected Poplar as this is a quality wood that is similar to what the German used pre World War 2.

We bought two 8’ planks and using our Radial Arm saw, ripped both of them to the desired width. We then cross cut them to the specified length of each part. Using a Dado blade (datto), we grooved some edges to receive the hinges later. We then used the router to mill a few pieces to receive the half mortise lock. The drill press took care of creating our counter sink holes exactly where they were needed so we could screw all pieces together.

Then it was time for integration tests with both boards and the Mega.

Once everything performed as it should, we inserted all 5 screws in place, adding the perforated top plate.
Then the button caps and then the alpha labels on the keyboard. (1 hour total).

At that moment, we had a completed, tested, working Enigma Mark 4, but no enclosure.

It was then time to “make a box”.

For our client in Florida who ordered a custom built Enigma, (is this you?) we decided to document the whole build, step by step.

First was the assembly of the main board, (2 hours) then the daughter card (2 hours).

We then dropped the sketch on the Arduino Mega.

Final assembly with laser cut & routed text on Top plate, along with keyboard alphabet labels.

SUCCESS! Boards are populated & tested & work great!
We are now in business with our fully functional Enigma Replica. Available for sale at www.stgeotronics.com, these can bring your geocaching challenge to another level…

In response to the popular demand posted on our instructable, we created a pair of Prototype PCBs to make it easier for anyone to build his own Enigma Replica. They showed up during the Thanksgiving holiday & we are now busy populating & testing one to make sure it works just great. Please go to stgeotronics.com if interested. We also offer it as a kit, and as a fully assembled & tested device.

Our eCommerce Web site has finally arrived!

You can now order directly from our web site any of the devices we have been blogging about. We accept PayPal only.

Thank You.

Can I buy one LBE Pro/Mini Production Serial 1 of 10!

Enigma is completed & fully functional!

It behaves exactly like a German M4 & can decrypt anything that the real thing can encrypt with any Rotor combination!

It now has its own Travel Bug so it can be discovered. It also has an Instructable that is currently Featured on the front page of Instructables.com. Go check it out!
