## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5134:1` (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/ADA5134:1.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

## Description 

THE REACTOR'S MELTING DOWN! GRAB THE FUEL CORE, JENNA, AND EVACUATE THE COMMAND CENTER! With this **Rotating LED Warning Light with Adjustable Volume Buzzer Alarm,** you can monitor and easily alert humanoids as to the status of a project, machine, or even if the bathroom is occupied!

This alarm is very very simple - provide anywhere from 3V to 12V DC to the two power wires, and the LEDs inside start lighting up in a rotating manner. If the volume knob is turned up, you'll also get an incredibly-annoying buzzer sound as well.

If you want to turn this on only sometimes, you'll want to use a [power transistor (like the venerable TIP120)](https://core-electronics.com.au/tip120-power-darlington-transistors-3-pack.html) or [power FET (like this nice N-Channel MOSFET)](https://core-electronics.com.au/n-channel-power-mosfet-30v-60a.html) to enable or disable power. Since it isn't inductive, you don't need a protection diode. [Adafruit have an example guide on using transistors to power a high current item here](https://learn.adafruit.com/transistors-101/example-uses).

If you want something with multiple colors, Adafruit got some really nice [tower lights here](https://core-electronics.com.au/search/?q=tower+light).
