Hmm.. the many ba's is at an odd offset.. don't you want them only at
equal offsets?


Maybe like this?

s = "5b3000ba00260bababababababababababababababababa000bd1007bd10b810ba92"
p s.scan(/\G(?: (?:ba)+ | (?:(?!ba)..)+ )/x)
# ["5b3000", "ba",
"00260bababababababababababababababababa000bd1007bd10b810", "ba",
"92"]
