This is a very nice video. Thank you for posting it. I noticed your website at the conclusion of the vid and am looking forward to checking it out. I'm working through my first bridge rectifier circuit (converting a 12.6AC signal to dc), and seeing how the capacitor affects the rectified signal was very nice. I've read about using a bleeder resister as well. Would that be useful, and how exactly would one wire it up? Thanks again, this looks like a lot of fun.
Very nice. I am curious how did you solve the ground problem? I always had trouble when using a signal generator directly without a transformer. I couldn’t isolate the source signal from the oscilloscope ground and the result was a half-wave rectification due to bad grounding. Very cool using LEDs though!
very good demonstration of Full wave rectifier + filter. i was just wondering what that ripple was on the un filtered sine wave. i wish i had my own cro :(
I just had to replicate your project. It's so cool. And I realize now that the 5V is due to voltage dropping across the diodes. I added a wrinkle to your design by using a wall wart with a 9v AC output rather than the usual DC. I didn't have a signal generator like you have. Of course-- the AC goes off and on so fast you can't tell it's happening. But my meters prove that I have AC going in at 9V and DC coming out at 5V.
I wish there were more vids like this. Makes it much easier to understand concepts. REALLY wish you'd put up a schematic with values. Especially want to see what reduced the 9v to 5v.
Very decent demo on this schematic. The use of the two scopes really put it down clearly! Loved the addition of the cap to demonstrate the smoothing effect. Your time making this vid was very well spent! Keep up the great work.
AWESOME :)

Why get 5volts DC why not 9 volts :O??

@ImUrtastyflava The voltage drop over a LED is ca 2V. 9V-2V-2V=5V.

@1sunstarter66 I used a differential probe, the black box in front off the right scope.

very good...a goog idea your project using led´s on the place of the diode´s.
congratulations..
I liked.

One of the BEST demonstrations I have ever seen to show whats really happening! SALUTES!!!

Great job, sometimes I wanted you to talk but you covered everything in bubbles. Overall a very good, well presented video. Thanks

thats quality! and helped me so much cheers mate! what were the specs on that cap you used ??

very good demo. Cool how you show how the filter capacitor smooths out the DC signal.
