An interesting kit to build and use, the kit produces 16 different sounds and can be controlled by on board switches or external coding. Two 14 pin ICs are provided, a 4066, quad bilateral switch, and a 4011, quad two input nand gate.
The kit contains 27 parts, one of which is a COB (Chip On Board). Construction notes and full instructions are included along with a 3 x AA battery carrier. This kit is extremely good value for money. Some soldering is required.
