The Whadda Possessed Pumpkin XL Soldering Kit (WSXL108) doesn't need any carving, but you will need to solder all components onto the unique gold-plated circuit board. The components include colorful RGB LEDs that have a special diffused effect.
Once the soldering work is finished, the LEDs will perform 5 different light effects that you can choose thanks to the onboard button. The onboard ATtiny chip is pre-programmed with these animations, so your kit will work once you power it with the included adaptor. Place the pumpkin on a mantlepiece or behind a window to scare all those who pass by.
