Vital Chamber Idea but no idea where to begin

[Darkwanderer]

I have an idea to creat a device that works like a bed your sim can sleep in it but gain energy faster and fun. and other sims that watch it can gain logic. its the water tank you see in Sci-fi movies "Resident Evil Movie" Alice is in that water tank while Scientists are looking at the screens just an example. i have drawings of it and ideas in what it will do and what it looks like, but i have nothing to make it come alive and im not requesting this i just need a little help here. Where do i begin in making a project like this?

Learn to make textures (object recolouring tutorials), then meshes (object meshing tutorials). That will allow you to make the actual object itself, just not functional. Then learn some BHAV tutorials to get into modding (I believe what you actually need to mod is BCONs but it's pretty similar, IIRC).
