i just got a new unicycle and i wanted to make a video. any ideas on how to make a good hat-camera
Helmet cam video is kinda boing.
Get someone else to video you.
Do NOT buy a cheap helmet cam like the Tony Hawk, they are terrible.
If you search this thing called “Google” you might find what you are looking for 
i am sponsored by GoPro helmet cams, for motocross. they make good cameras for a good price. www.goprocamera.com check them i love mine.
i 100% agree i worked at a bike shop that sold those ones and there amazing vertually bomb proof too . yes we destroyed one but the guy was doing mach chicken on a dh course and decieded to hug a lift pole
