Hey all, today I was given a special gift (well, I paid $24, but it was a gift nonetheless): a microphone pre-amp circuit (with mic integrated) AND a 0.5 Watt Mini Amplifier! Wow. I built both of them during class, it took about 1h30min to do both, and test. They are so awesome, the amp especially, so I made a video.<\/p>\n

My first attempt at video blogging. Unscripted, edited to remove screw ups. Oh, technology… In any case, the mini amp<\/a> is friggen’ awesome! A very simple design, aside from the IC, and the mic pre-amp<\/a> is even simpler. I’m not sure if I am allowed to post this or not (if its copyrighted, let me know and I’ll take them down), but I’ve scanned the schematics in case anyone was interested in building their own. Of course, those two links are direct links to the inexpensive kits, so if you don’t feel like looking for the parts, you can order the kit with all the parts.<\/p>\n

I was really quite impressed with how powerful the amplifier was. It is strong enough to drive my two-way, dual 6″ sub, floor-standing speakers, and create enough bass to feel in my pant legs and vibrate on my desk, equivalent to the volume I’m listening to music with my home theater amp right now. My predictions earlier at school were right: it would be equivalent to normal listening volumes. According to the equalizer display on my amp, it says about 0.1watts are going to the speakers right now. Now, I should be able to overtake any radio station with my FM transmitter!<\/p>\n
