LM386 Chip Amp

"It's always handy to have a little amp kicking around to trace audio signals, test mics, CD tape and TV audio outputs. You know, something that doesn't weigh a lot and isn't clumsy. There are tons of uses for this little circuit."

First Paper Transistors Produced

A team of Portuguese scientists have created the first Field Effect Transistor (FET) made with cellulose fiber-based paper. The new approach takes a common sheet of paper and uses it as the dielectric layer on oxide FETs, with devices fabricated on both sides of the paper sheet. And while other teams have reported using paper as the physical support (substrate) of electronic devices, this method is the first one that also allows the paper to be used as the interstrate component as well.

In other words, it's really cool.

More than a proof of concept, the team envisions its new paper transistors being used in disposable electronic devices like paper displays, smart labels, smart packaging, bio-applications, RFID tags, and more.... Full details will be published in the September 2008 issue of IEEE Electron Device Letters.

Capacitors Bypassing Effectiveness

I've done this both in my Nad cdp and yestarday i've done the same in my Musical Fidelity X-A1 integrated amp using Elna Cerafine and Rubycon caps, and i always have great results.
