Amplifier.cd - measuring instruments - audio

The Content consists of theory, test, analog technique and measuring instruments for amplifiers, electronics and Hifi. by Ralf Richard Ohmberger

Amplifier.cd - measuring instruments - audio

Amplifier.cd - measuring instruments - audio

A Tutorial describes fundamental ideas of electro-technology and the general amplifier and audio technology. The test equipment gallery shows measuring instruments - older, historical and partly new.

Obsolete Test Equipment Gallery

The gallery shows measuring technique, with which electronics are developed. Some are special and classic devices, which are still in use and some already represent a historical value. Many of these devices have special functions, which are very popular. The side does not intend to show newest test equipment from the portfolio of the manufacturers (some devices excluded).

One Watt Mains LED Lamp or Tubelight

Lots if Light on One Watt, yes this works, but should be built by those experienced in High Voltage usage and Knowledge of insulation techniques.

Home Made Circuits.

This has to be encapsulated in a insulated fire retardant plastic enclosure. You can change the values around what is indicated to experiment with types of White LED available.

One Watt Mains LED Lamp or Tubelight

This project is not for Youngsters or those who are still learning. High Voltage can cause injury and can be fatal too, when used or applied without experience, training or supervision.

Arduino and Freeduino Knowledge

Things are easier than before, there is so much more you can do with this. Starting with a Embedded Project with Arduino type of uC is easy. A PC USB inteface for testing your code. Analog Interface is good for trying out Measurement or Robotic Projects.

Freeduino began as a collaborative project to publish open-source Arduino-compatible production files. The files that resulted from this project allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware. Over time, Freeduino has come to mean hardware that is "Arduino-compatible".

Arduino and Freeduino Knowledge

Freeduino is a free-form version of the Arduino, in that is not developed under a centralized design process.There is no Freeduino team, or anyone to ask permission of: anyone, anywhere, can design and produce a Freeduino product, no questions asked, no royalties paid.

It's sort of like electronic harware anarchy- or democracy, depending on how you look at it. We derived the Freeduino files from Arduino for exactly this reason: to see what the Arduino project would have looked like if it had open hardware distribution and manufacturing.
