I have built a full adder that completes all calculations in 2 ticks. This differs from my very compact adders by not using XOR ot XNOR. I have compacted this design, but I believe there is a lot more room for improvement in future small versions of this adder. I built this using torches, dust, glass and target blocks.

This adder works via cross-inhibition and NOR gates. So there are two core rails; these are directly linked to the A and B inputs, respectively. Each core rail has a torch at the end, which directly acts on the sum output. Each core rail has a cross-inhibitor that uses a torch to invert the opposite rail's input onto the core rail it outputs on. When carry is turned on, this will directly inhibit both core rails, preventing an output sum. For all other cases, there are two NOR gates directly acting on the sum: the first one takes the inverted carry and the inverted OR of both A and B; the second NOR also takes the inverted carry and a signal made from the inverted A ORed with the inverted B.

The carry circuit has a NOR gate with inverted A and B inputs acting directly on Cout, followed by another NOR gate that also acts directly on Cout; this one has two inputs: the NOR of A and B, combined with the inverted carry.

This has been implemented in Java.

This mechanism can play from 2 to 9 music discs. It has a lever that can turn the mechanism on and off as soon as the record finishes playing its song. The music discs need to be put in the dropper (the music discs are chosen randomly) (you need hopper minecart for this)

This TNT cannon has 7 different angles to shoot from (45 L, 33.69 L, 18.43 L, 0 Middle, 18,43 R, 33.69 R, and 45 R), 4 power options for firing (Power 1 (Red on Right):~60 Blocks,Power 2 (Yellow on Right):~150 Blocks,Power 3 (Green on Right):~270 Blocks,Power 4 (Blue on Right):~390 Blocks), and an option to choose between High explosive (top sign right of window)(More Damage)(More Spread) and Precise fire (bottom sign right of window) (Less Damaging)(Less Spread). There is also A new option to choose if you want the TNT shot to spread out some to hit those tricky targets between two angles! when the lever on the left of the window is put downwards there will be no spread, but if its flipped up there will be more spread. YOU CAN ALSO NOW SHOOT AT MORE THAN ONE ANGLE PER SHOT! Flick as many levers as you want on the left side of the control pannel (Concrete levers).

I have been able to make a compact full adder with a carry propagation of 2 ticks. This design still only uses torches and dust and remains within a 6 by 2 by 8 form factor, giving it a bounding box volume of 96.

I have made some changes from the previous design due to slow carry propagation and sum. The main change that made this possible was removing the final torch from my XOR gate, which converted it into an XNOR gate. For the carry, the NOR of A and B (this is already part of the XNOR gate) is then directly combined with the inverted carry-in in a NOR gate (carry NOR). This step is where the two-tick carry propagation occurs. Then the last component of the carry comes from the XNOR gate, which has already computed the AND of both A and B inputs; this is then directly ORed with the carry NOR output.

For the sum, a second XNOR gate is used. Wired with the output from the first XNOR and the carry input (which had to be un-inverted). This gives a sum speed of 4 ticks.

I have been able to tile this adder with a one-block gap between each adder. I have uploaded a schematic file for this on my MineMev(RUBENHILLIER).

7 different angles to shoot from (45 L, 33.69 L, 18.43 L, 0 Middle, 18,43 R, 33.69 R, and 45 R), 4 power options for firing (Power 1 (Red on Right):~60 Blocks,Power 2 (Yellow on Right):~150 Blocks,Power 3 (Green on Right):~255 Blocks,Power 4 (Blue on Right):~360 Blocks), and an option to choose between High explosive (top sign right of window)(More Damage)(Less accurate) and Precise fire (bottom sign right of window) (Less Damaging)(More accurate).

Sorry for the reupload. Something was wrong with the structure, but the issue is fixed! I hope you enjoy building and using my creation!
