Alarm Clock to Turn on Stereo

For some reason, I am not waking up to my alarm clock anymore. It is pretty loud already.<p>I want to wire it to turn on a home receiver and a CD player that will play a CD to wake me up. Obviously, this is partly for fun since there are other approaches that are easier.<p>With DC, I would need a re...

Water Filter

The water at our house tastes pretty bad. We have a Brita water filter system that we use for drinking water. <p>One problem is the icemaker in the freezer. It is fed the same water and tastes terrible when it melts. As a result, we have been buying bagged ice from the store. This gets to be expensi...

Need Ideas for College Project

I have been assigned to do a collage for an art project that is based on our interests.<p>It can be more than just pictures on a paper. He described a previous project where Christmas lights were used around a cardboard box, etc. <p>So, now I have the desire to do something with electronics. I have ...

Re: Capacitors

Glenn,<p>THD wasn't really what they were testing for.<p>The cap was put inline while everything else was left the same. The voltage dipped to the same level with the capacitor while the input signal was left the same.<p>So, if the capacitor does nothing to prevent a voltage drop, the amp is going t...

Re: Charging 12V Battery while riding Bicycle

To keep a battery charged, does the charger have to exceed the battery voltage by a certain margin?

Electronic Components

I was reading through some posts and have come across a lot of components that I have never heard of.<p>Such as tuning capacitors, disc capacitors, and crystal resonaters just to name a few from the 1.5 volt clock thread.<p>Is there a good site that thoroughly explains the components I may come acro...

Capacitors

I've been heavily into car audio the past few years. <p>One question that is often posed is whether or not capacitors are useful in providing a stable input voltage to the amp. Many believe that a capacitor will eliminate or greatly reduce the voltage drops that occur when the audio amplifier draws ...

Re: New here

Awesome Mike.<p>Do you have a rough estimate of the total parts cost?<p>What impedance is it rated to put out the 68 watts at? What is the input voltage? 120vac or 12vdc?<p>Thanks for the time you put into making schematics to help others understand it too.

Re: New here

Thanks a lot for the warm welcome!<p>I looked at your site yesterday, Mike, and I saw you were going to have an audio amplifier project. I can't wait until you get the schematic up. <p>The only site I've found so far that has been extremely helpful is <p> www.bcae1.com <p>I'll probably have some stu...

New here

Hi<p>I just came across this forum while searching for something.<p>Based on the current threads, it seems very interesting.<p>I am new to electronics except for some audio amplifier repair that I do as a hobby. <p>Just wanted to introduce myself and I hope to learn some stuff.<p>Thanks
