I'm waiting for the open source version of the Sarco Pod.. They originally stated they would release it if it became operational (the open source plans) but till now they haven't. From an engineering perspective, does anyone know if they'd be hard to D.I.Y? I would imagine not, as it's just a bigger version of CTB using gases, i think. like instead of something to hold the gasses in but only covering your head, it covers your whole body..so a bigger bag?
