Get a glass circle-cutter, then get that gun from another thread and just shoot the power button or channel buttons every once in a while. If you can shoot a doorbell from a block away, certainly no one will get hurt trying this

*disclaimer*
I cannot be held responsible in any way, shape, or form for your inability to grasp sarcasm and to realize you shouldn't ever use a glass circle-cutter for nefarious reasons, and even a lot of not-so-nefarious reasons.
