Method automated bus catching mechanisms

[Eedrah]

So far, I've generally lacked the courage to "pull the trigger". I've been considering setting up some kind of automated mechanism that would initiate the action. I imagine its viable in engaging many different methods, but I'll explain the two specific cases applying to my personally selected methods. I've put together a small CO generator. As I've set it up, all I have to do is put a tubed mask on, pour the formic acid into the addition funnel, and breath, I would lose consciousness very quickly. I've spent an aggregate of hours just sitting there with the mask on, holding the bottle of formic acid over the funnel, just too weak and scared to pour. I know that I'll inevitably conjure the courage, but as many of us here know, things often get worse over time, courage comes with more terrible desperation, and I'd really like to get this over with before it gets worse. I am hoping to assemble some kind of liquid release for the formic acid, on a timer, so I have some level of separation. Any ideas or insight on this would be appreciated.

Any extra component makes a method more prone to failure - but that's just me.
As for your setup specifically - if you want to go that way, maybe some gardening supplies would help you? There are sprinkle control devices that open and close water valves at specific time.
