**Rock, Scissors, Paper Adjudicator**- -2 sets of 3 inputs,
*r,p,s* - -2 outputs
*o1,o2* - if a winner,
*o1*or*o2*goes high, other low - if no winner, both outputs are low
- if only one pressed, both outputs are low
- for any error condition, both outputs are high

- -2 sets of 3 inputs,
**Hex to 7 Segment Decoder**- -4 inputs
- -7 outputs
- outputs are to drive 7 segment display for any input from 0 to F.

All digits must be unique!

**Braille Number Encoder Circuit**- -4 inputs (binary representation of number up to 9)
- -6 outputs
- output the braille representation of the input number

**Braille Number Decoder Circuit**- -6 inputs
- -4 outputs (binary representation of number)
- output the number of the braille input

**Fox, Goose, Corn Solver**- -4 inputs;
*fox_here, goose_here, corn_here,*and*shore* - -3 outputs,
*take_fox, take_goose,*and*take_corn* - output indicates which object farmer could transport for each case
*shore*indicates which shore the farmer is on

- -4 inputs;
**Binary to BCD Decoder**- -4 inputs
- -5 bits of output
- output is BCD value of input binary number

**Stable Isotope Number**- -4 inputs, giving atomic number for the first 10 elements in the periodic table
- -3 outputs, binary representation of the number of stable
isotopes of the element

**Most Common Stable Isotope**- -4 inputs, giving atomic number for the first 10 elements in the periodic table
- -? outputs, binary representation of the number of
neutrons in the most common
stable
isotope of the element

**Digits of**Pi- -4 inputs, giving binary number of decimal place (up to 10)
- -4 outputs, giving binary value of the corresponding
digit of Pi
(for input of zero, output should be binary value
of '3')

**Digits of e**- -4 inputs, giving binary number of decimal place (up to 10)
- -4 outputs, giving binary value of the corresponding
digit of e (for input of zero, output should be binary value
of '2')

**Numbers in the Fibonacci sequence**- -3 inputs, giving binary value of a number
- -4 outputs, giving binary value of the corresponding
number in the sequence (For instance, an input of 3 should give the
3rd number in the sequence, which is 2.)

**Number of factors**- -4 inputs, giving binary value of a number
- -3 outputs, giving binary value of the number of
factors, including one and itself, that the input number has.
(For instance, an input of 6 should give 4, since
the factors of 6 are 1, 2, 3, and 6.)

**Order entering confederation**- -4 inputs, to give binary representation of province or territory.
- -4 outputs, indicating what order the province or territory
became part of Canada. (The original 4 provinces would all have order
1.)

**Number of prime ministers from each province**- -4 inputs, to give binary representation of province or territory.
- -?? outputs, indicating how many prime ministers were born
in that province or territory.

**Provincial/territorial ocean access**- -4 inputs, to give binary representation of province or territory.
- -3 outputs, indicating which ocean(s) (if any) the
province or territory has access to, directly or by river.

**Hexadecimal to Roman Numeral**- -4 inputs, giving binary value of a number up to 15
- -? outputs, identifying which symbols are needed to indicate the
value in Roman numerals.
(The outputs will be X, V, and a few I's, but
*the order is important*, since you need to distinguish 4 from 6, and 9 from 11.)

**Month details**- -4 inputs, to give binary representation of month.
- - output indicating whether or not the month has 31 days

- output indicating whether or not the month contains an equinox

- output indicating whether or not the month contains a solstice

- outputs for 4 seasons, indicating whether any of the month is in the given season
