That page has the reader download a .hex file into a Microbit and hold it to a screen to receive a secret message that must then be decoded using a Caesar Cipher.
The decoded word is appended to a bit.ly link and a landing page with more challenges is shown.
As I do not have a Microbit, I went about it a different way.
In the end I could solve both challenges using only Excel (and a web page to do the Caesar for me, but could be done solely in Excel as well).
The mission, should you choose to accept it, is to visit the page above and crack the message without using a Microbit. Use whatever tools you deem necessary. In the process you might learn a thing or two about technology and yourself.
In order to not publish the solution where search engines will find it and spoil the challenge, we can communicate here using Enigma encrypted messages.
If you want to take it easy on me, use 3 rotor machines, it takes me forever to come up with the initial settings for 4 wheel machines, maybe one day I will automate it.
