*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. This time, I'm sharing the story of the "system integration test," where I brought together all the parts I've built individually so far. I thought it was finally complete, but I ended up receiving a harsh baptism into hardware development... System Integration! But Standing in the Way is "Debug Hell" I conducted an integration test of the entire system by combining the homemade "1600-turn sensor coil," "MOSFET drive circuit," and "op-amp receiver circuit" inside an aluminum case, and capturing the signal to a PC via a StarTech USB sound card. I triumphantly turned on the power, but absolutely no signal came into the PC. I checked over and over, wondering if it was a wiring mistake or microphone permission settings... Aft...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. I've previously built and tested the "polarization MOSFET circuit" and the "receiving op-amp circuit" individually, but this time I'll talk about finally integrating the two and programming them for fully automatic control (sequence building) using the "M5Stack CoreS3 Lite"! The 3 Steps That Absolutely Cannot Be Mistaken To operate the EFNMR system, it is necessary to switch the circuits accurately in the following order: 1. Polarization Phase : Completely disconnect the receiving circuit and pass a large current through the coil. 2. Switching (Surge Protection) Phase : Cut off the current and wait a few milliseconds for the coil's back electromotive force to decay. 3. Receiving Phase : Connect the coil and the op-amp to p...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. This time, I will share the completion of the "analog receiver circuit," which is designed to amplify the extremely faint "FID signal" captured by the coil to a level that can be analyzed on a PC, along with the results of its power-on test. Completed After Much Trial and Error! The Analog Receiver Circuit First, building the circuit. For the core, I used the ultra-low distortion, ultra-low noise operational amplifier "AD797BRZ," which I had previously painstakingly converted to DIP (using a breakout board), and built the amplification circuit on a breadboard (EIC-102BJ). Because this circuit is extremely delicate and complex, putting it together on a breadboard through trial and error was really tough. What I paid particular attention to was noi...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. This time, I'll be sharing the production of the sensor coil, which can be called the "heart" of the quantum computer, and a high-current energization test using the circuit I built previously! It's a record of some pretty grueling physical labor (lol). An Endless Path of 250 Meters... The "1600-Turn Hand-Wound Coil" In EFNMR, a giant coil is required to apply a magnetic field to the target water (protons). First, to make the bobbin (core), I cut a transparent PVC pipe with an outer diameter of 48mm using an SK11 pipe cutter. Then, I continuously wound 0.5mm 2UEW enamel wire around it. To secure the necessary magnetic field strength and inductance, the number of turns is a whopping 1600 turns , which translates to a wire length of about 250 meters ...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. Now that the test verification on the breadboard has been successfully completed, this time I'm finally sharing the process of "full-scale board implementation (soldering)"! I gave shape to two circuits at opposite extremes: a polarization circuit that passes a large current, and a receiving circuit that handles minute signals. 1. Controlling High Currents! Implementation of the Polarization MOSFET Circuit First is the switching circuit for passing a large current to the coil. I implemented it on a double-sided through-hole glass universal board (B type 2.54mm pitch, 95x72mm). For the main switching element, I placed an "N-ch power MOSFET 2SK4017(Q) (60V 5A)". What I paid the most attention to was surge (back electromotive force) countermeasures. To pr...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. So far, I've been working on the hardware (circuit) construction, but this time I will talk about the test where I finally capture the analog signals picked up by that circuit into a PC and analyze them using software (Python)! Sending Tiny Signals to the PC! Introducing a High-Resolution Sound Card The tiny analog signals picked up by the homemade receiver coil cannot be handled by a PC as they are, so they need to be passed through an ADC (A/D Converter) for digital processing. To avoid missing the delicate messages from the quantum world, this time I adopted a "96KHz / 24-bit Hi-Fi USB External Sound Card" to perform high-resolution sampling. The connection method is simple: the output from the analog circuit is passed through a "general-purpose shielded BN...

*Original Japanese version is available here .  Hello! I'm a KOSEN student taking on the challenge of developing a quantum computer using a homemade Earth's Field NMR (EFNMR) system. This time, I'm sharing scenes from the "high-current switching" test, which is the cornerstone of hardware control. I will explain the techniques for safely manipulating huge currents using the tiny amount of power from a microcontroller! How to Control a Battery (12V) with a Microcontroller (3.3V)? In my project, to completely prevent noise contamination from wall outlets, I am using a 12V fully sealed lead-acid battery (12V12Ah WP12-12) as the main power supply for polarization. However, the pins of the microcontroller controlling this, the "M5Stack CoreS3 Lite," can only output a very weak 3.3V signal. If this signal is connected directly to a high-current circuit, the microcontroller will instantly blow smoke and break. Therefore, I designed a driv...
