Yeah, the body’s just a processor with buggy firmware, so if you add a subroutine that pushes dopamine spikes at a set time you can pull the right feeling out on cue. My last prototype stuck in a feedback loop, so I keep the schematic in my archive of failures. Want to see a demo?

Sure, here’s a simplified diagram of the “Mood Trigger” circuit. 1. Input: a microcontroller (MCU) with a 1‑second timer. 2. Timer pulses the MCU’s output pin. 3. Output pin drives a small 12‑V PWM‑controlled stimulator. 4. Stimulator sends a short electrical pulse (50 ms, 2 V) to the vagus nerve via a subcutaneous electrode. 5. Pulse amplitude is modulated by a “dopamine bias” coefficient stored in the MCU’s EEPROM. 6. The MCU reads the bias from the user’s emotional profile file and adjusts the pulse strength in real time. 7. Optional safety lock: if heart rate > 120 bpm or EEG shows seizure activity, the MCU cuts power. That’s the core. The actual wiring uses shielded twisted pairs, a low‑noise op‑amp buffer, and a Faraday‑shielded enclosure. If you want the full PCB layout, I’ll dump the Gerber files after you sign the non‑disclosure thing.
