They use the same technology as your wireless charging pad, but they're a lot smaller
Adding functional lights to a Lego construction is a fun way to take it to the next level, and the firm even puts light-up components on some of its sets, such as a luminous Christmas tree. However, because to the same technology that enables wireless charging, this brilliant hack allows adding illumination into a project ridiculously simple.
The Lego technique to lighting parts entails a battery-powered brick with an LED inside that is bright enough to shine through other transparent pieces. The LED brick rests within a Christmas tree in the latest Santa's Visit holiday set, but its glow can be seen from the outside through translucent tiles that function as Christmas lights. There are aftermarket lighting options for Lego, however they involve transparent pieces that have been modified with tiny LEDs that are connected to a power supply through extremely thin cables. Those cables may be mostly hidden away with appropriate design, but not totally, and they can be delicate, so taking a Lego Batmobile for a drive with functional headlights may not be the best idea.
YouTuber Cultural Gutural has devised a possibly superior approach to illuminate a Lego structure that eliminates cables and architectural constraints, and the gear is inexpensive and easily accessible online. A wireless phone charger has a wire coil that, when activated, may generate a current in an adjacent coil without touching it. It is what allows smartphones and wireless earbuds to charge wirelessly, and it is also why the technology is also known as inductive charging. It cannot power a gadget such as a smartphone without a battery, but it can readily power tiny devices such as low-energy LEDs.
This $20 AliExpress kit comprises wirelessly powered LEDs tiny enough to put inside transparent Lego bricks (not flat panels) and illuminate on their own when placed near a thin power coil. The light-up bricks may be blended with other bricks and even piled eight bricks tall while still shining, as Cultural Gutural illustrates in this video. The intensity of the small LEDs decreases as they move away from the supplied power coil, however numerous coils could be added into a display base, or even into a bigger model itself, extending the range of the wireless power transmission.
Unfortunately, despite the fact that the idea was submitted to the Lego Ideas platform—where builders can share their custom creations in the hopes that the company will turn them into real sets if there is enough fan support—Lego ultimately rejected the submission, citing the platform's strict rules that prohibit the use of non-existing Lego bricks and parts. It may one day inspire Lego to create its own version on LEDO (as this creator refers to them), but for now, it's a really easy and basic update that's less than most Lego sets.
