- This is a case exclusively for the iPhone 16 Pro Max.- Shipping will be in the order received.- An LED (1 unit) without a battery will light up.- It does not light up normally, but lights up when a strong radio wave is emitted.- This is a set of an iPhone case and a Tokyo Circuit Diagram A5 clear file (green or black)!──────────The FLASH Kansai Circuit Diagram iPhone Case features a single red LED implemented at Osaka Station that lights up without a battery.The LED lights up by converting the radio waves emitted by the iPhone itself into power and boosting the voltage. It does not light up normally, but lights up when a strong radio wave is emitted. Since it lights up with the iPhone's radio waves, it lights up randomly.It is more likely to light up when using information-rich apps like Google Maps, or when the iPhone is searching for its location in an elevator or underground mall.The mechanism for lighting up involves an antenna circuit on the back of the circuit board catching the weak radio waves emitted by the iPhone, which then travel to the front of the board. An amplification circuit on the surface increases the voltage and current to make the LED light up.The circuit that lights up an LED without a battery was patented in 2020 (Patent No. 6667777).──────────A circuit board cannot be made without designing it with PCB CAD.Since PCB CAD is not design software, lines are drawn one by one with a mouse.It is meticulously designed with a 0.1mm wiring pattern for thin lines.Only three colors are used: gold (gold plating), PCB ink (overall green, black, white), and PCB ink (station display white, black).While maintaining the surface design, the "circuit that lights up an LED without a battery" is wired on both the front and back surfaces of the circuit board.──────────A 2mm red LED is implemented at Osaka Station, 2mm resistors at 13 major stations, 1.6mm resistors at 28 stations with high passenger traffic, a 1.6mm capacitor at Esaka Station where the PCB ART moeco factory is located, and 1mm electronic components at the remaining 176 transfer stations. A total of 219 stations have electronic components implemented.The coverage extends west to Akashi Station, south to Wakayama Station, east to Kyoto Station, and to Kameyama Station in Mie Prefecture. A large ship is depicted on Osaka Bay. Station names are represented by three white silk characters (e.g., OSK Osaka).──────────After implementing the electronic components, they are coated one by one with resin in a cleanroom (Class 1000) by hand until the surface tension fills the resin, protecting the implemented parts. Bubbles on the components and dust on the resin surface are removed manually. The product is designed and manufactured in Japan, and all products are RoHS compliant (lead-free). The circuit board is gold-plated. It comes in a gift box and can be used as a gift.──────────The material used for the iPhone 16 Pro case and iPhone 16 Pro Max case is TPU (thermoplastic polyurethane). TPU is a polymer compound that combines the supple elasticity of rubber with the toughness of hard plastic. The case has a strap hole.──────────■ Product SpecificationsFLASH Kansai Circuit Diagram iPhone 16 Pro Max CasePrice: ¥16,200 (tax included)Colors: Green, Black, WhiteSize: 165mm x 82mm x 13.5mm (camera lens area)Weight: 52gElectronic Components Used: LED (1 unit), Resistors (193 units), Diodes (12 units), Capacitors (13 units)Magsafe & Wireless Charging: Usable (OK)
