I was thinking similar. Many masks on Etsy have a pocket built in the back so you can slide insert in an N95 filter. The mesh in that filter is rated to trap the microscopic aerosolized droplets that get through lesser quality filters. Replace often as needed and you are safe. Adding a filter pocket would be a good inclusion to the design.

Cool looking and terrific video.

Gonna try this. When ordering components noticed that the 1K resistor is not on the parts list. I too would be interested in a instructable mod that adds a flow timer

I keep thinking this might be improved by slipping the cut off Q-tip into a holder of some kind. Ballpoint pen or Sharpie etc. that have been trimmed and gutted. Even a mechanical pencil, pin drill. or electric eraser that all have (reuseable) mini collets. Something to give stability to the cardboard QTip and better griping for big hands.https://www.amazon.com/WSD-Sketch-Mechanical-Pencil-Sharpener/dp/B07MY2WCTC/ref=sr_1_17?crid=1CQJPT50GYVTV&dchild=1&keywords=mechanical+carpenter+pencil&qid=1586452665&sprefix=mechanical+carpenters%2Caps%2C229&sr=8-17https://www.amazon.com/s?k=pin+drill+hand&crid=2FX9BV66GHYFY&sprefix=pin+drill%2Caps%2C221&ref=nb_sb_ss_i_5_9https://www.amazon.com/Tihoo-Electric-Automatic-Additional-Replaceable/dp/B075Q66BMY/ref=sr_1_7?dch…

Very good!Wonder if it would be possible to do iris art as a photo or computer illustrated art then paper print the iris and glue in a cut cone shape?
