Can you help me make DFAs for "begin and end", "at most three 1s", "no substring", and "mod" please! I'm confused on how to make them.

begin and end: {w{0,1}w begins with 010 and ends with a 0} at most three 1s: {w{0,1}w contains at most three 1's }. no substring: {w{a,b,c}w does not contain the substring acab }. even odd: {w{a,b}w starts with a and has even length, or w starts with b and has odd length }. mod: {w{0,1}w is the binary expansion of nN and n3mod5}. Assume represents 0 and that leading 0's are allowed. A number nN is congruent to 3mod5 (written n3 mod5) if n is 3 greater than a multiple of 5 , i.e., n=5k+3 for some kN. For instance, 3,8 , and 13 are congruent to 3mod5
