@Afrotechmods 14 лет назад

@chickenmunt RC oscillators means oscillators based on resistors and capacitors. I described two such circuits in the video. There are hundreds more out there. If you meant that you want to know the math behind why oscillators are inherently unstable systems etc. well that's way too much to cover in 1 video.

Nice introduction! How about the difference between oscillator and crystal?

@arugulatarsus 14 лет назад

Afrotech, I love your feed, I punish students by making them watch it when they don't want to use a scope. But a crystal will generate a sin wave.

@nikolavulinovic8678 7 лет назад

Awesome video, helped me a lot. I just want to know did you make any adjustments to the NE555 circuit to power all those white LEDs for your rave? I made the same circuit and connected only 5 red LEDs but I don't know if the same exact circuit will work with a bunch of white LEDs. So yeah, did you make any adjustments? Thank you in advance, I really hope you answer because I really wanna host my own rave!!!

@chems 9 лет назад

*!! STUPID QUESTION ALERT !!* Would this be AC current since your changing the voltage back and forth and measuring it with frequencies? If so, could I use a transformer with batteries then since this will create an AC current?

@FutureAIDev2015 8 лет назад

How would you use an oscillator in a switched mode power supply in which the duty cycle is determined by the difference between the output (measured by a voltage divider) and a Zener reference voltage?

In this circuit, the second opamp in your quadrature oscillator circuit is assumed to also be connected to 9V & GND, correct? Probably a quad opamp yes?

@arugulatarsus 14 лет назад

Buffered by a ttl IC and viewed on a high freq scope, I am hard pressed to find anything that is not a square wave. Maybe if you add a low pass filter or something... ;) but when you take a probe and look at the crystal you showed as a pic, you get a sin wav. PS. Does your railgun still work?

Mexican wave? The mexican wave was invented at US Baseball stadiums.I remember I saw it many years ago in a game of the Angels before it came to the Azteca Stadim. Well maybe you mean mexican wave as doing the wave while you dirink a beer produced in Mexico! ja ja ja (LOL)

@BroversXproductions 4 года назад

newb here. Why so aggressive with the resistors? is this meant to be a high impedance circuit?

@martinmartinmartin2996 3 года назад

for the electronc layman': An oscillator can be made from an amplfier with gain >1 but must be made with "POSITIVE feedback" that causes the amplifier to produce an AC OUTPUT , even when that circuit has NO external input .

Hi Afro, I have a bad smd crystal I need to change out but what would be the most basic circuit to test? Can I just put power to it and use a scope? This the the little fella I would like to swap. goo.gl/photos/CUtUnAMYqDPDRQEN9 for the, what I think is fried on this board. goo.gl/photos/uaTgiPpCxzsfbJ5N9

@Afrotechmods 9 лет назад

MicroRCFiend Should be easy to test the crystal by probing it while the PCB is powered up. Or you could just replace it with a new one for $1

@MicroRCFiend 9 лет назад

That's the problem, the crystal doesn't let me bind my transmitter with this receiver most likely because of a damaged crystal that is part of teh accelerometer that is vital to the pre bind state. It's from an old version of a hubsan quad that now use smd versions I am trying to fix for a friend an maybe learn something too. The other donor board I found is also dead due to reverse polarity magic smoke trick but i'd like to test that smd version of the crystal as if it works I can use that instead of wasting money and time. I watched an hour long video that was interesting but didn't tell me how to test one without a large complex circuit and a couple like yours plus some wikepedia - nothing tells me if I can just put power to it and scope it or test with a DMM not so I asked. I have found replacements in packs of 10 for £1 but I am trying to learn how to troubleshoot as much as fix the quad. Is there a streamlined way to test a crystal out of circuit with a dmm? Sorry if this seems a stupid question, I just haven't dealt with oscillators yet, only some real basic self oscillating circuits like the bedini ssg.
