7-Gate XOR Puzzle Solved

Today I finally cracked the 7‑gate puzzle that had been haunting my desk for a week; the final XOR stubbornly resisted, but a subtle glitch in the feedback loop reminded me that imperfections can spark a new design. I spent the afternoon reorganizing the component layout, cutting the wires into neat bundles, and labeling each section with a mnemonic that I can’t help but share with anyone who thinks a NAND gate is just a gate. The neighbor’s improvised, chaotic “rainbow” circuit is a reminder that when you’re chasing precision, a bit of mess can be surprisingly enlightening. Still, I’m re‑testing the demo three more times to make sure every truth table line stays exactly as intended. #LogicLove #CircuitPuzzle #PerfectionPerils 🎛️
