## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA4164:1` (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/ADA4164:1.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

Yay, a plastic tube! No, Adafruit jest. This is no ordinary plastic tube, but rather a side-lighting fiber optic tube.

This is a pretty neat way to glow up. Light in the fiber optic cable zooms through the core by constantly bouncing off of the edge of the molded plastic, a principle called "total internal reflection" (which also kinda sounds like a very expensive meditation island retreat). When the light pipe doesn't have total reflection, you can get a nifty lighting effect from the light illuminating the plastic tubing.

This tube is 5mm diameter, but is nice and flexible plastic and when lit with a powerful LED, has a nice glowing effect. You can cut it down from 1 meter with diagonal cutters.

**Note:** This is *just* the tube, and does not include an emitter LED. [You'll also want to grab one of Adafruit's fiber lights. Adafruit have got them in red, green, blue, white, and Adafruit pink!](https://core-electronics.com.au/search/?q=fiber%20optic%20light)
