Transistor connection in the discharge path of the 555 timer

AI Thread Summary
The discussion centers on the connection of transistors T1 and T2 in the discharge path of a 555 timer circuit. Participants express concern that the emitter and collector terminals of these transistors may be reversed, which could prevent the timer from discharging properly. The role of pin 7 as the discharge pin is highlighted, along with the charging of capacitor C1 through three diodes. There is a consensus that the transistors are incorrectly oriented for effective discharge control. Proper configuration of the transistors is essential for the circuit's intended function.

Pin 7 is the discharge pin. C1 seems to charge via the three diodes, and the purpose of T1 and T2 would be to control the discharge. I agree with you, they are around the wrong way to accomplish this.

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...
