This is an addition I came up with for Mumbo Jumbo's Tiny 3x3 Piston Door. It uses fire charges to light the portal and TNT to close it instead of lava or water. The piston door acts as the "Iris" for the portal which is why I call it a stargate. The design is not without its fair share of bugs but it is still fun to have another way to turn portals off with TNT.
