## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5141:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5141:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Adding LEDs to anything makes it 5x better -- its a scientific fact! But when you have LEDs, you've got wires and power supplies and all that stuff is kinda annoying. What if you could have LEDs that light up without any wires or soldering or battery packs? Sounds magical! That's what makes this **Large Inductive Coil and 10 Wireless LED Kit** so nifty. It uses electromagnetic fields and inductive coupling to pass power through the air to light up lil LEDs soldered onto coils.Each order comes with one driver board (you'll need a 24V power supply to power it) and ten miniature LED inductors in an assortment of colors (two each of white, blue, yellow, green, and red).

Inductive charging is a way of powering a device without a direct wire connection. Most people have seen inductive charging in a rechargeable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil.

In this product, Adafruit have one reeeeeeeeeeallly large coil that forms the 'primary' of the power charger. Then, each individual LED has a smaller coil on the back. When the two couple, power is transferred from coil to LED and it lights up. You can have a large number of LEDs, all in different 3D space above or below the coil. You can also have them in different orientations, although you will get the best efficiency/power transfer when the two coils line up. You can also have the LEDs slightly outside the main ring, but, again, they'll not light up as bright as if they're right in the center.

These are often used for model makers, toy designs, or displays but we think there's a lot of potential here for art or craft or cosplay. The coil is large, but you get about 6" of vertical space to work within.

These are basic modules, and Adafruit don't have any datasheets or specifications for them. [Use the pre-soldered barrel jack to power up with 24V](https://core-electronics.com.au/24v-dc-1a-fixed-2-1mm-tip-positive-appliance-plugpack.html).
