I’ve built my own arc reactor…
Btw, Iron Man 2 was disappointing. Not recommended.
Actually, this is a LED battery-powered motion detector. When a moving object is detected by the IR sensor (max 5m range at 120°), the LEDs light up. Light intensity & duration can be varied. Bought on eBay for $4.15 (Rs 130).
