This is a great product! It worked perfectly first time, and provides a very realistic feel for how the Apollo Guidance Computer actually worked. The screens even have the indicator lights in a light gray when they're off, just as if there was a bulb behind a plastic legend. It was very well packaged and shipping was fast, Came with the needed cable, and the online documentation is clear and straightforward. I'll be enjoying this item for a long time to come. No complaints at all...definitely worth the price!

This Was The BEST Kit Ever!

For Sinclair Scientific Calculator Emulator

I have never got more enjoyment or satisfaction out of any project in my life. It is an absolute miracle that a Sinclair Scientific Calculator could be accomplished with a chip that could hardly do multiplication & division (and ran on only 324 words of instructions.) The creation of this calculator represents the triumph of the human spirit over the impossible. One hundred Hewlett Packard Engineers swore that this couldn’t be done. Nigel Searle (& now Arduino Enigma) have proved them wrong!

Best Project Ever!

For Sinclair Scientific Calculator Emulator

A Tour De Force! Absolutely Brilliant! The Sinclair Scientific Calculator Emulator from Arduino Enigma was my most enjoyable project EVER! Unsurpassed quality, unparalleled documentation & exhaustively detailed instructions: You could tell that this Project was TRULY a Labor of Love by this Project's Creator! Thank You Arduino Enigma!

Excellent!

For Sinclair Scientific Calculator Emulator

Excellent kit. Easy to buld. I very enjoy it. The chip is already preprogrammed - thank You.
It was working on first time. Only thing I dislike is Power On switching in down direction.
This calculator gives fun on party. Almost nobody knows RPN and mantise E.
I love all gadgets with Sinclair logo.

Great kit, easy to build and a cool calculator to learn RPN

For Sinclair Scientific Calculator Emulator

This is a great and simple to assemble kit. All you really need is basic soldering skills and you can put this together in under an hour. Everything is included including batteries to power it up after you've finished. The source code is open and you can learn a lot poking around the very elegant small code base that makes the Arduino Nano emulate a vintage Sinclair Scientific Calculator. And you can finally have a platform to learn Reverse Polish Notation (RPN) the mathematical entry format that this calculator uses. Overall a grade A+ kit.

Great Enigma Simulator

For Arduino Enigma I, M3, M4 Machine Simulator w/ Case

Works flawlessly, only thing needed was to download the .hex code and burn it into the Arduino.

Only bad thing, is that it needs external power supply either by USB-B cable or 9v battery. I put inside a LiPo battery, a LiPo charger and a 5v stepup with a small switch. Can be seen here: http://karman.cc/blog/archives/940

Also to complete the kit a separate hinges should be bought. Would be great if included with the kit. Also, I miss to be able to see the Arduino source.

A great model of the Enigma machine.

For Arduino Enigma I, M3, M4 Machine Simulator w/ Case

Just received my Arduino Enigma. I have been exploring it's features, and it seems to be a fully configured working model. I'm sure I will enjoy exploring it over the coming days. Have to assemble the case, and perhaps upgrade to the latest version, all part of the fun. The online documentation is complete and easy to follow, and response from the maker was quick and concise.

I'd recommend this as a great way to learn about this classic machine.

Great simulators!

For Arduino Enigma I, M3, M4 Machine Simulator w/ Case

I enjoy working with it. T is a recreation of an important piece of history that saved many Allied lives during WWII.

IT'S A GREAT SIMULATOR!

For Arduino Enigma I, M3, M4 Machine Simulator w/ Case

THIS ARDUINO ENIGMA SIMULATOR IS EXCELLENT. I'VE GOT TWO OF THEM. THEY WORK PERFECTLY. THEY DON'T NEED AN EXTERNAL KEYBOARD AND THAT MAKES THEM VERY PORTABLE.
