Self-Assembly Electronic Kit (Soldering Required)

Ability Level 2: ModerateThis is a classic 'Ding-Dong' door chime sound generator kit with a low standby current.

We supply extra capacitors in the kit so that you can experiment with the 'Ding' and 'Dong' duration's. Oscillator frequency is set at 64kHz by a 510K resistor but you can change this to give the tone of your choice.

The kit includes a COB sound module, a motherboard for the supporting components, a 3" (75mm) diameter speaker, push switches, components and battery holder. Switch wire is not included (simple 2-core bell wire is fine).

N.B. This kit requires a reasonable level of soldering skill and it not recommended for beginners.

You can also purchase just the COB sound modules only without the additional components supplied in the kit.
