Product description
Halloween Ghost with Two Pulsing Eyes. Electronics kit with surface-mount components (SMD). Build a pulsing Halloween ghost that blinks faster when you hold it. This simple and fun SMD kit is ideal for anyone who wants to try soldering surface-mount components.
The kit consists of a printed circuit board with an operational amplifier (LMV358) that drives two red LEDs. When a battery (CR2032) is connected, the LEDs slowly pulse, creating an effect reminiscent of a living ghost in the dark. Apply pressure to the touch-contacts to make the eyes pulse faster.
The design includes 10 surface-mount components and can be assembled using a standard soldering iron. Assembly instructions and a component list are included.
