The FLASH Kansai Circuit Board Map iPhone Case features a single red LED integrated at Osaka Station that lights up without a battery.
The LED lights up by converting the radio waves emitted by the iPhone itself into electricity and boosting the voltage. It does not light up under normal conditions but activates when strong radio waves are emitted. Because it reacts to the iPhone's radio waves, the lighting pattern is random.
It is more likely to light up when using data-intensive apps like Google Maps or other map applications, or when the iPhone is searching for location information in elevators or underground malls.
The mechanism behind the lighting involves an antenna circuit on the back of the board that catches the weak radio waves emitted by the iPhone. This energy travels to the front of the board, where an amplification circuit increases the voltage and current to light the LED.The circuit that lights an LED without a battery was patented in 2020 (Patent No. 6667777).

A circuit board cannot be created without designing it using PCB CAD.Since PCB CAD is not design software, every single line is drawn manually with a mouse.The design is meticulously crafted with wiring patterns as thin as 0.1mm.
Only three colors are used: Gold (gold plating), PCB ink (Green, Black, or White for the base), and PCB ink (White or Black for station indicators).The "battery-less LED lighting circuit" is wired between the front and back of the board while maintaining the aesthetic design of the surface.

A 2mm red LED is mounted at Osaka Station, 2mm resistors are at 14 major stations, 1.6mm resistors are at 27 high-traffic stations, a 1.6mm capacitor is at Esaka Station (where the PCB ART moeco factory is located), and 1mm electronic components are mounted at 173 other transfer stations. Electronic components are mounted at a total of 216 stations.
The map covers as far west as Akashi Station, south to Wakayama Station, and east to Kyoto Station and Kameyama Station in Mie Prefecture. A large ship floats in Osaka Bay. Railway station names are represented by three characters in white silk-screen printing (e.g., OSK for Osaka).

After the electronic components are mounted, each case is individually hand-coated with resin in a clean room (Class 1000) until the surface tension is full to protect the components. Air bubbles on the components and dust on the resin surface are removed manually.
Designed and manufactured in Japan, all products are RoHS compliant (lead-free). The circuit board is gold-plated.The product comes in gift box packaging, making it suitable for gifting.

The material for the iPhone 14 Pro and iPhone 14 Pro Max cases is TPU (Thermoplastic Polyurethane). TPU is a polymer compound that combines the supple elasticity of rubber with the toughness of hard plastic.The case includes a strap hole.
