Minecraft Survival Prison (redstone)

I'd like to have a large and secure prison built on a minecraft survival server. I will gather all the needed resources myself and give more precise instructions on what elements to add myself. Should include multiple piston doors, automatic kill checks through dispensers, an auto-regenerating cobblestone cell, a bed trap for the cell, an ender pearl stasis chamber for the guard and composter x-ray glitch machines. The prison itself is simply an obsidian box, no outside architecture or design required. This is still quite a complex project which needs advanced redstone knowledge.
