- This is a case exclusively for the iPhone 14 Pro Max.- Shipping will be carried out in the order of received orders.- An LED (1 piece) implemented without a battery lights up.- It does not light up during normal use; it lights up when a strong radio wave is emitted.- Set includes an iPhone case and a Tokyo circuit diagram A5 clear file (green or black)!
──────────The FLASH PARIS circuit map iPhone case features a red LED (1 piece) implemented on the Eiffel Tower that lights up without a battery.It converts the radio waves emitted by the iPhone into power, boosts the voltage, and causes the LED to light up.It does not light during normal use; it lights up when a strong radio wave is emitted. Because it lights up with the iPhone's radio waves, it lights randomly.It is more likely to light up when using data-rich Google Maps or map apps, or when the iPhone is searching for location information in elevators or underground malls.
The lighting mechanism involves an antenna circuit on the back of the circuit board that catches the weak radio waves emitted by the iPhone and routes them to the front of the board.On the surface, there is an amplification circuit that increases voltage and current to light the LED.The circuit that makes the LED glow without a battery was patented in 2020 (Patent No. 6667777).
──────────The circuit board cannot be produced without designing it in CAD.Since CAD is not a design software, each line is drawn manually with a mouse.It is designed with fine wiring patterns of 0.1mm in diameter.Only three colors are used: gold (gold plating), circuit board ink (green, black, white for the entire board), and circuit board ink (white, black for station labels).
While maintaining the surface design, the circuit for "LED lighting without a battery" is wired on both the front and back surfaces of the circuit board.
──────────For the Eiffel Tower, a 2mm LED is used; for the Arc de Triomphe, a 3.2mm resistor; for the Louvre Museum and the Orsay Museum, 2mm resistors; for major buildings, 1.6mm resistors; and for other buildings, 1mm electronic components are implemented.The names of the buildings are expressed with three white silk characters (e.g., ORS for the Orsay Museum).Major street names are also written in white silk characters.
──────────After installing the electronic components, each component is manually coated with resin in a clean room (Class 1000) until the surface tension causes the resin to fill completely, protecting the components.Bubbles and dust on the surface of the resin are carefully removed by hand.Designed and manufactured in Japan, all products are RoHS compliant (lead-free).The circuit boards are gold-plated.They are packaged in gift boxes, making them suitable as gifts.
──────────The materials for the iPhone 14 Pro case and iPhone 14 Pro Max case are TPU (thermoplastic polyurethane).TPU is a high polymer compound that combines the flexible elasticity of rubber with the toughness of hard plastic.The case includes a strap hole.
