Answer: Binary Secret #327

The secret message is:

Nice work!

Row by row

Row	Bulbs	Add the ‘on’ numbers	Character
1	01001110	64 + 8 + 4 + 2 = 78	N
2	01101001	64 + 32 + 8 + 1 = 105	i
3	01100011	64 + 32 + 2 + 1 = 99	c
4	01100101	64 + 32 + 4 + 1 = 101	e
5	00100000	32 = 32	a space
6	01110111	64 + 32 + 16 + 4 + 2 + 1 = 119	w
7	01101111	64 + 32 + 8 + 4 + 2 + 1 = 111	o
8	01110010	64 + 32 + 16 + 2 = 114	r
9	01101011	64 + 32 + 8 + 2 + 1 = 107	k
10	00100001	32 + 1 = 33	!

Crack it with Python

Python can do the adding for you. int(code, 2) reads a string of 1s and 0s as a binary number. Then chr() turns the number into its character.

secret = [
    "01001110",
    "01101001",
    "01100011",
    "01100101",
    "00100000",
    "01110111",
    "01101111",
    "01110010",
    "01101011",
    "00100001",
]
message = ""
for code in secret:
    number = int(code, 2)
    message = message + chr(number)
print(message)

When you run it, it prints:

Nice work!
