Hi there, my knowledge of electronics is very limited and I am just learning by reading online and experimenting.
Recently my group of friends learned that we could install LED lights into toys that were used on gaming systems that would read a NFC tag ( chip) on the base of the figure. We would use 30GA insulated wire, about 35 inches of wire coiled at the base of the figure and when the game console would power on and scan it would turn on the LED that was attached to the toy. Problem is, it would blink. We made a few toys for friends but one person could not accept our gift because she feared the blinking might trigger an epileptic seizure. We read online that we could use a capacitor to store energy and give a steady stream of energy to the led. Recently in December the Disney infinity toys came out with pre-installed LEDs. They used a capacitor like we figured we would use in their chip. We tried scanning how much voltage a Disney portal NFC scanner used and it jumped from 13V to 20V back and forth. The Official toy with the pre-installed LED uses a 70mf 470Mf 25V KSC -40+105c PET Capacitor. We realized we did not understand how a capacitor worked when we tried adding one of these capacitors to our set up. 3mm LED connected to 35 inches of insulated wire adding the capacitor to the loop did nothing. We reversed the capacitor in case it was a polarity issue but it still did nothing when scanned. Here is a picture of the official chip, with a capacitor that provides constant steady energy to the LED. http://infinityinquirer.com/wp-content/uploads/2015/12/Screen-Shot-2015-12-03-at-11.10.41-AM.png?e087de http://infinityinquirer.com/wp-content/uploads/2015/12/Screen-Shot-2015-12-03-at-11.10.54-AM.png?e087de This is a great site where the person tore apart the figure and explained all he found. What are we doing wrong or are we missing to make our capacitors work with our NFC antenna? Or is a chip required with additional pieces? ( Sounds like it) Any help will be appreciated.
