What is it?

A kit to make a Pseudo Random Number Generator (PRNG) for the RC2014. It is based on Linear Feedback Shift Register (LFSR) technology

Why did you make it?

To help me calculate random lottery numbers :-)

More seriously, a PRNG can be useful for a bunch of other things, including but not limited to:

• Generating test sequences for other circuits (counting up and down is not always the best way to test)
• As a component of a crypto
• As a source to scramble serial data
• (Together with a low pass filter) as a white noise source

It just depends how geeky you want to get...

What makes it special?

My testing shows it has better randomness characteristics that RC2014 BASIC's SW Random Generator. If you use the latter to pick lottery numbers, my tests show it will pick 27 more often than 10 (to take just one example).

It offers a choice of clock inputs:

• The system clock
• Its own clock, running at approximately 2kHz and deliberately not synchronised with the system
• An external clock, used to clock out a serial stream

Its output is available as:

• An 8 bit word (address selectable) using BASIC standard "INP" command
• A binary serial stream

What's included?

A PCB and all components required are included, including sockets for all ICs. A PDF with full instructions is available at the link below.

What else do I need to know?

MG011 has been designed for RC2014 with reference to the RC2014 Module Template. All pinouts used and the physical outline are in compliance with the RC2014 Module Template.

RC2014 is a trademark of RFC2795 Ltd.

MG011 has been designed for hobbyist use only and is not to be used for safety or business critical applications. MG011 is not designed to be used to support cryptographic or transmission security functions protecting data of any kind of value or sensitivity at rest or in transit. The kit assumes basic through-hole soldering skills.

The payment of any import taxes and duties will be the responsibility of the Buyer.
