Supersniffer 2000 - robot fart detection device
You should also work on design of the moutpiece's "screen" IMO.. At least you should have a version with finer screen or make it easy to insert a screen from the top.. When i have dry herb which crushes to dust .. it is likely that i eat some or the abv clogs the screen i have installed to prevent eating because there is space between the smile and the screen which gets filled.. Anyway that is not a huge pain.. I just pull out the mouthpiece and blow black to free the airflow and take hit again.. I also have success putting some damiana as a filter between the mouthpiece and the load but it also makes harm to airflow sometimes..
