Jaycar Electronics Papanui is an electronics retail store at 45/49 Main North Road in Strowan, Christchurch, part of the well-known Jaycar chain and rated 4.4 on Google.
A good electronics shop works as part help desk, part store: the difference shows at the counter, where someone can look at a burnt plug or mystery cable and match it to the right part. Regulars bring the dead item with them — the fuse, the remote, the frayed lead — since matching a connector in the flesh beats describing it. The stock in shops like this runs from drawers of switches, resistors and connectors to hobbyist boards such as Arduino and Raspberry Pi, alongside power supplies, tools and car and security gear.
For anyone in Christchurch with a repair on the bench or a project in mind, the Papanui store puts that world of parts within easy reach.
