[Lee Davison] acquired an Acer laptop that didn’t have a display anymore. He had enough parts on hand to add in an LCD panel and give it a CCFL backlight. But when he started looking for an inverter to drive the backlight he couldn’t find one. What he did have on hand were some smashed screens that had LED backlights … Read the rest

Want to shoot lighting bolts from your hands to punish your enemies? You can (almost) do just that with this static electricity generator hack.
