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...

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...

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 ...

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...

Dean : <p>I have dual runs of 0 gauge to my amps. They draw around 300 amps at full tilt. <p>Recombinant Gas batteries can be used inside a vehicle, I believe.<p>Not sure about the caps ability to stay charged even for music with quick beats. Based on the test, it drops in sync with the system with ...

Perfect site...thanks.

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

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...

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 ...

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.

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...

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
