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

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.

PCBWay - PCB and Assembly Services

This is a Sponsored Post, The contributions from these Sponsor Firms help enhance and improve the delabs websites and services.

PCBWay -  PCB  and Assembly Services

PCBWay is a PCB manufacturer in China. They offer the most cost-effective PCB prototype services. The also manufacture larger quantities and provide product assembly services.

Axiom: 100kW motor controller

It is a 3 phase motor controller. It takes a DC voltage and generates 3 sinewaves for driving a motor, conceptually similar to those small ESC for drones and bikes. The difference is that this particular setup can safely work with a 400V battery, flowing 300Amps all year long.

"In order to give support to many electronic enthusiasts who want to build projects but do not have enough money, PCBWay is the first manufacturer who gives them at a low price."

Six reasons why PCBWay is the best PCB manufacturer

Considering a large proportion of electronics enthusiasts are students or beginners, PCBWay has created dedicated channels for sponsorship to encourage these electronics enthusiasts to create their own projects. PCBWay has sponsored more than 1000 projects so far which include robots, rockets, racing cars and so on. PCBWay has also sponsored Makerfaire, SHA2017 and other activities.

Fritzing is Product Design or EDA in Simplicity

"Fritzing is an EDA - Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard.."

Fritzing is Product Design or EDA in Simplicity

"in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing."

Fritzing Starter Kit to start learning Arduino

What do you get? The ultimate beginners book teaches you everything you need to know through a series of practical--yet playful--exercises. And that playfulness is the key! There is a paper robot who can turn his head; a fortune teller who is (of course) never wrong (no guarantee on that); a dinosaur who relays the news on your Twitter stream and a pong game on a big LED matrix display.

Fritzing Starter Kit to start learning Arduino

Fritzing's goal is to provide easy tools for documenting and sharing physical computing projects, producing layouts for Printed Circuit Boards (PCB) and teaching electronics.

    Amazing Jacob's Ladder

    So how do they work?  First two conductive metal rods are positioned in a rough “V” shape with a slight space between them at the base.  A sufficient voltage differential is provided from a high voltage transformer to breakdown the air in the gap between the rods.
