Did you make an LC oscillator or a Twin-T oscillator?
Was its output a square wave?
Did you use an LM386 power amplifier instead of using an opamp?
Please post your schematic.
If he meant "comparator" the LM386 is an audio amplifier isnt it?
Also, all the images/attachments in this thread are completely missing so it makes this entire thread completely worthless. In fact less than worthless because it's here but there are no images to look at to follow the dialog so we cant see the circuit in question.
Yes, and that's a very very bad thing for a technical forum or web site for obvious reasons.
It effectively makes the threads with images totally useless and a waste of space, and probably very very annoying for newcomers who want to read the once very useful information.
I agree with MrAl whole-heartedly. Might as well close the site down if image removal is now policy.
I'm wondering if image loss is part of a bigger problem. Just recently when trying to access this site I've had delays of 1min or more 'Waiting for www.electro-tech-online.com', plus various pop-ups reporting 'data-base access error'.
