Stuart and Jochen have created an excellent BOM here: www.subzero.plus.comand here: http://www.handheld-competence.de/dsky/dsky_bom.htmlPlease visit.

Yes of course! You may event want a 20x4 LCD as this would give you even more room to display things like key setting and decrypted/encrypted message. Our inspiration (Kid's Game to Arduino Enigma Machine by sketchsk3tch) used an LCD.

Thank you for the compliments and feedback.We did consider using Cherry keys, but we have been using similar buttons in our Open Enigma for 4 years and have never had issues so we elected for the simplicity and ease of use of these integrated lighted buttons.Our Open DSKY runs on 6 AA batteries (9 volts) and although we did not leave a unit on until batteries are dead (yet), we believe that depending on battery quality, user selected brightness of Neopixels and 7 segments, number of lights turned on... the 6 AA should work for a whole week or more... The screw terminal can be used to directly hookup any 9 volt power brick if desired.

The banana connectors on Article 0 were just for show to act as a plugboard. On subsequent units, they are used for real physical plugboard.

@FrancescoS21 Good luck with your project.Rotor 1 is wired "EKMFLGDQVZNTOWYHXUSPAIBRCJ" so is A = 0, B = 1, C= 2, etc then E = 4, K = 10 and M = 12, etcRotorvals are the actual values of the rotors going in towards the reflector for encryption. Rotorsvali is the inverse effect: when they are bouncing back from reflector going through the rotors in reverse order.P.S. You will have faster reply from me asking the question through our e-commerce site "contact request".

First of all Kurtex, we suspect that you created your Instructable account for the single purpose of promoting a different maker’s project (or perhaps your own) to our followers. We consider this piggybacking. The excessive comments advertising another company, and the fact that you have no instructable of your own and you have not contributed to this community shows that you should probably reconsider your membership with instructables. Insonicbloom has earned the right to comment here as he is actually a Maker. He has authored a nice instructable to show people how to sequentially blink LEDs without the use of any micro-controller or 555 timing chip, flip-flop, decade counter, etc. Using simply 3 transistors to charge/dischage caps sequentially. It is a very cool project, very i...

It is a very cool project, very inexpensive to build, easy for beginners. Highly recommend it. Kudos to his craftiness and creativity.

We have waited several days to post an answer to this question as we needed to adequately research this other maker replica. Finally found it on the web. Here is a Telemetrics employee showing how they perform a “light test”. This is how the same lamptest is done on a Raytheon DSKY and on our Open DSKY. After viewing these 2 lamptests, should the idea of browsing the internet and running Linux on a screen smaller than your phone borrowing your keyboard and mouse from your computer, encased in a very nice DSKY looking box appeals to you, then Telemetrics has you covered. However, if you want an Open DIY DSKY Replica where YOU can participate as much as you want and has built-in expandability supported by a wide community, then S&T Geotronics has you covered.Our Open DSKY ...

However, if you want an Open DIY DSKY Replica where YOU can participate as much as you want and has built-in expandability supported by a wide community, then S&T Geotronics has you covered.Our Open DSKY will execute as many Verbs, Nouns and Programs as humanly possible without an actual Saturn V engine or retro-boosters attached. Oh, our Open DSKY will be totally identical in size with the original when we release our password protected servo motor actuated concealment storage as an alternative back for the Open DSKY. This will allow some DSKY owners to hide their firearm or plutonium or favorite blend of herbs or spices inside their DSKY which is obviously out of scope in this instructable.Second, we haven’t seen a completed unit from Telemetrics. But we can tell you with reasonable certainty that the Telemetrics “Replica” is a very different animal indeed. It looks nice. However, we feel it is not a DIY project. Is it available as a kit? Can you download the files today and make your own? Hmm. This is Instructables.The real Raytheon DSKY contains no computer whatsoever and runs no code. It is merely a DISplay and KEYboard device. We have added to our display & keyboard a real Arduino Open Source microcontroller and an array of input and output peripheral devices which can easily be programmed/modified by any end user.A DSKY that can send/receive email, surf the interwebs and manage your stock portfolio seems to us a little out of scope compared to the original. And why would anyone want to run Linux on that tiny screen? We played with the 5” TFT LCD many years ago for our Open Electric car conversion and even considered it for our Open DSKY.http://evmaker.tumblr.com/day/2013/01/05/Fact: The MIT AGC computer that the DSKY connects to had 32K of ROM, 2K of RAM, 15 bit architecture on a single processor core and operated sub 1 MHz.Fact: Our Arduino microcontroller has only 32K of ROM, only 2K of RAM, a 16 bit architecture on a single processor core and operates at 16 MHz.Fact: The original AGC processor obeyed 36 finite machine instructions.Fact. The ATMega328 does have more commands, however it can process the same 36 instructions on a machine language level.Our upcoming Open AGC simulator to connect to the Open DSKY (if desired) will run all of the Apollo missions as well as interface to Kerbal Space Program. While our Open AGC will not contain as much Rope Core memory as the original, we will thread (and share via Instructables) a few bytes of Rope Core that actually works. No mechanical relays due to power consumption limits.These are 2 different product and there is room for both and many more as mentioned at the very top of this instructable.This is a DIY Open Source Kit. We learned very quickly from our Open Enigma instructable that different people put different levels of “Y” in DIY.The unit you mention looks very interesting and nice. Is it available as a kit? Can someone other than Sam build it? Can I download its STL files? Is a PCB offered at minimal cost? Everyone has access to the MIT code on GitHub, is this unit emulator code available?Kurtex, P.S. A lamptest on our unit is done by pressing Verb, the Number 3, the Number 5 and Enter. Works everytime. Just like on the real DSKY and more than likely on the one Fran Blanche is building. No mouse, keyboard, python shell script necessary…Our immediate reaction to your posts was to simply flag them as inappropriate which would remove them altogether. However, the other DSKY that you brought to light certainly has merit and your comments are helping people understand our product better thus generating traffic and interest.

Banana plugs and jacks are used to create a functional pluboard and fully functional cloth covered jumpers.

Attention everyone including Oscarbravo35, we have now posted all 5 required stl files to produce a complete Open Dsky. Oh, and we are currently Live on Kickstarter with some Early Birds discounts still available.

Because we are using Open Source software on Linux for our CAD Schematic drawing, we are currently working to draw the footprints for the components we used. There are no Arduino Nano, Maxim, etc, built-in. Sorry for any delay, we hope to have these schematics finalized soon.

starphire, thank you for bringing up the excellent effort from Fran Blanche. We have been following her progress closely, support her and truly believe that when she is done, she will have a DSKY that could fool Astronauts into thinking it was a real one. #no shortcuts. However, we first and foremost did not want to subject our kit makers to the high voltages required by authentic EL displays, did not have the ability or time to raise the capital required (~ $10,000) and also were not interested in figuring out how to fit 156 mechanical relays required to turn each segment on.

We are very impressed by both your patience/precision on assembling the paper kit and your skills in adapting it for lighting and button action. We bought the paper kit (and tools) with intention to assemble but I quickly (first night) realized I did not have the patience and time to accomplish the task.

Thank you for all your feedback. Good or bad, feedback is a gift.The schematic is currently being drawn and the STLs will be posted shortly.

Oscarbravo35, evbeurdn, Insonicbloom, vitalisam, camohatYou are all correct on both points. It is an expansive kit and we also feel an Instructable is NOT an Instructable unless the software code (INO in this case) and STL (if 3D Printed files involved) and schematic (if electronic circuits involved) and PCB layout are provided. We are really sorry about the 24 hour delay in providing these files, while we made sure the source code what available from day 0, we have just started added the other files to the instructable tonight. Step 4 (Schematic) will continue to grow in the next few days) but the neopixels wiring is posted, Step 5 (3D Printing) contains the Top plate and Bezel. Step 6 (Laser Cutting/Engraving) contains the Button Caps and Lampfield. Sorry about the delay.

Here is the full Arduino Production code for the GeoGuide.https://www.dropbox.com/s/u3op4enz57w0xdb/GeoTripS...

It is not possible on our Printed Circuit Board, but if you are building is from scratch, you can certainly use the dual or the quad...

Yes, If you go on eBay and look for IRF9Z34N (which are the same), you will find them for $1 to $2 a piece or less...
