Troubleshooting an Odd Square Wave Oscillator: A Scientist's Analysis

AI Thread Summary
A user attempted to build a square wave oscillator from an online schematic but found it non-functional. Suggestions included using a 555 timer IC or a 74HC4060 chip as simpler alternatives for generating square wave signals. The discussion highlighted that many online schematics may be unreliable, often created by amateurs rather than professionals. The user expressed relief at discovering easier solutions. Overall, the conversation emphasized the importance of using proven components for oscillator designs.

I found a schematic from the internet that was claimed to generate a square waveform at a decent frequency. I built the thing but it doesn't seem to work at all.

I'll attach a picture of the schematic. Could you tell me what's wrong with it and if there is any other relatively easy way to make a square wave oscillator?
I really don't like running to my electronics store to get every little component.. The clerk already knows me by name.. :D

You could just use a 555 timer IC -- that's a common way to do a simple oscillator. Or you could use a 74HC4060 combination oscillator and divider chip.
 
ok, thanks.

Heh.. I looked into it. I thought, it'd be a lot more complicated.
Thanks
 
Berkeman is right, much easier to use 555 and those "schematics" from the net usually never work, since they are put together by amateurs, not engineers.
 
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...
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...
