The instant repeater was first made by Jontis_00 for the UTD.[1] It was made in two different designs: one design that only worked when switching the input from on to off, and another that only worked when switching the input from off to on (this design didn't always work).
Tavirider was the first person to start making instant logic gates. He did this by making a clock, and the different variables were on, or pulsing. So he could make simple logic gates. Check out this video for more info.

This new design of an instant repeater was released by SethBling via YouTube. It is somewhat compact, and it could repeat the signal instantly. It did not send pulses like the previous repeaters, so when the input is off the output is off. When the input is on, the output is on.
A device that inverts the input, as such it is also called an "Inverter" Gate. It is very similar to the repeater, just it has a few things switched around.
A device where the output is off when at least one of the inputs are on. Almost the same as OR Gate, except here the player combined the lines before an inverter.
A device that requires both inputs to be ON for the output to be ON. Basically an AND gate is an inverted signal hooked up to a NOR Gate. Easy to make and VERY big, but instant.
A device that requires both inputs to be ON for the output to be OFF. Basically an AND gate is an inverted signal hooked up to a NOR Gate, then into an inverter. Easy to make and VERY big, but instant.
A memory device that switches between on and off with each pulse. In simple terms, you can make a button work like a lever. Very compact design, 100% instant, but works on falling edge of the input. To make it work on the rising edge, put an inverter before and after the T Flip-Flop.
