DC Lighting Control - Power 3 LED Strips

AI Thread Summary
To power three LED strips from a 12V DC source with options for simultaneous lighting, blinking patterns, or turning them off, using a 555 timer is suggested. However, the timer alone may not handle the required current for the strips. Instead, it is recommended to use the 555 timer to control a transistor or relay, which can manage the higher current needed for the LEDs. This approach allows for a simple and cost-effective implementation. Overall, this method provides flexibility in controlling the LED strips while ensuring adequate power management.

I currently have available a 12V DC source and from that I want to power 3 LED strips but I want to be able to either have them all on at the same time, blink the strips in a pattern, or have them off. I have done some research into 555 timers but it looks like they won't be able to handle the current. I'm looking for some ideas on how I can implement this simply and keep it on the cheap side.

use the 555 timer to drive a transistor or relay instead of directly driving the LEDs.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
