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.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
