Buzz Wire Game Kit – DIY Steady-Hand Circuit with Buzzer & LED, STEM Model
Build the classic buzz-wire game: guide the loop along the twisting wire without touching it, or the buzzer and LED go off.
Designed by Mematrix Lab
Description
A steady-hand game that teaches circuits
This kit builds the classic buzz-wire game on a blue base. Shape the wire into a twisting track, fit it between the two yellow posts and wire it to the buzzer, LED and battery box. Guide the loop on the wand from one end to the other: if the loop touches the wire, the circuit closes and the buzzer and LED go off.

Shipping
Standard shipping: $9.00 for the first item, +$1.80 for each additional item. Free shipping on orders over $260.
We ship worldwide, by default with economical international post (UPU / China Post small packet) to keep shipping costs low. Orders are usually handed to the carrier within 2–5 business days, and economical international post then takes about 10–30 business days to arrive; these are estimates, not guarantees. Delivery time depends on the destination and on postal and customs handling. If you need your order by a certain date, email us before ordering: faster shipping can be arranged, with the extra cost charged at the carrier's actual rate. Items that contain batteries or magnets are marked on their product page and ship by a special carrier line; some countries and regions cannot be reached by that line, and if yours is one of them we refund the order in full.
Batteries & magnets
This item contains, or may contain, batteries or magnets (for example in a motor, speaker or rechargeable battery). Ordinary postal parcels with such items may not pass security screening, so it ships by a special carrier line, and its price includes a $10 surcharge for this. Some countries and regions cannot be reached by this line. If yours is one of them, we will email you and refund your order in full.
Customs & duties
Import duties, taxes and customs requirements depend on the destination country, the shipping route and the local customs office, so we cannot say in advance whether any will apply to your parcel. Customs may hold a parcel, ask for more information, or ask for duties or taxes to be paid, even when the declared value is correct. If you have a question about your country, email us before ordering.
