Hey thanks alot,
i was reading like crazy last hours and also stumbled over the 555-timer.
Since i am not really from that field i yet dont know how to properly put that together to work.
so for what exactly do i need the resistors and capacitors or better do you have any circuit sketch for that?
I still didn't got exactly how to use that 555-timer. I saw in the sheet, that there has to be some control-voltage to set up the right flickerspeed, right? And therefore i do need the capacitor and a resistor, right?
Since i will buy here, i just post you the 555-timer, i probably would buy if it is the right one:http://www.conrad.de/ce/de/product/177113/Linear-IC-ST-Microelectronics-NE555-Gehaeuseart-DIL-8-Ausfuehrung-Praezisions-Timer
And here is the sheet:http://www.produktinfo.conrad.com/datenblaetter/175000-199999/177113-da-01-en-IC_NE_555_TIMER_DIP_8_STM.pdf
There are also circuit sketches... but i still don't get it completely.
Maybe someone can explain the circuit needed in short - that would be awesome!
Put a 555 timer on each LED on your walls so they all flicker at 33khz. It can have a small battery, 555 timer at 33khz, and one IR LED. Use ten batteries, ten LEDs, ten 555 timers, twenty resistors, ten capacitors, and place them on your walls at 10 locations.
