first, welcome to the site, lots of great info here for ya,
if you look thru some of the past years condo post, theres tons of photos of condo's.
a 5 gal. spackle bucket, loaded with stones/cement with 1" pvc pipe is all you need. not sure where your fishing but 15 to 20 feet is a good depth to start. (for winter fishing)
make about 5 of them, drop them in an area you like, the fish will find em, just drop them strait down with a double line and once it hits bottom, let go of one end and pull the line back up,
good luck and stay safe
