Cheap Sound Sensor for AVR

Alexander Weber I searched the web for a cheap method to let the ATmega respond to sound. My knowledge in analog circuits is very limited, but what I do remember, is that you can not attach a electret mircophone to a controller pin. The signal of the microphone is just too small and has to

My baby Tesla coil.

I started building Tesla coil by first learning how to build an inverter from DC supply. I found an inverter circuit here made by Joshua D. Wyatt, from this link. There, he used the inverter circuit to power EL backlights and fluorescent tubes, so the output is about 127 VAC as he claimed.But I want 1kV or more to make at least 1mm purple plasma as Tesla coil usually produce! (30kV is required to make 1cm length plasma). Therefore i use MOSFET IRF 840 as a transistor for high switching rate (als.......

Hobby radio broadcasting

While the term is used in many different ways, on this blog I would suggest that hobby broadcasting is about trying new ideas and exploring interesting concepts. Unlike community radio, which is focused on the audience, I feel that true hobby broadcasting is mostly about the broadcaster. Trying new frequency bands, using different content delivery modes and exploring little used technologies .......

You win

When I moved to Seattle, I lived a gray shingled apartment building on Northeast 67th Street, a speedy bus ride to the UW, where I had just started school. My apartment had deep-pile carpet the color of weak tea and a floodlit view of a parking lot, but it was mine, mine mine mine mine mine mine mine. Even getting a utilities bill was exhilarating: it was in my name! I bought cheap produce at the stand a few blocks east, found a good Thai curry place a few blocks to the west, and got takeout fro.......
