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 under normal circumstances, but illuminates when a strong radio wave is emitted. Since it lights up from 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 map applications, 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 and transmitting them to the front of the board. An amplification circuit is built on the surface, increasing the voltage and current to illuminate the LED.The circuit that lights up an LED without a battery was patented in 2020 (Patent Number 6667777).

A circuit board cannot be manufactured without designing it using PCB CAD.Since PCB CAD is not design software, lines are drawn one by one with a mouse.It is meticulously designed with a fine wiring pattern of 0.1mm.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 are implemented at 13 major stations, 1.6mm resistors are implemented at 26 stations with high passenger traffic, a 1.6mm capacitor is implemented at Esaka Station where the PCB ART moeco factory is located, and 1mm electronic components are implemented at an additional 164 transfer stations. A total of 205 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 floats in Osaka Bay. Station names are represented by three white silk characters (e.g., OSK Osaka).

After implementing the electronic components, to protect them, each component is individually coated with resin in a cleanroom (Class 1000) by hand until the surface tension is filled with resin. Bubbles on the components and dust on the resin surface are then removed by hand.Designed and manufactured in Japan, all products are RoHS compliant (lead-free products). The circuit boards are gold-plated.They are packaged in a gift box and can be used as gifts.

The material for the iPhone 14 Pro case and iPhone 14 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.
