Radio Electronics Magazine at Archive.org
Hugo Gernsback, sometimes called The Father of Science Fiction, started it as Radio-Craft in July 1929. The title was changed to Radio-Electronics in October 1948 and again to Electronics Now in July 1992. In January 2000 it was merged with Gernsback’s Popular Electronics to become Poptronics.
Gernsback Publications ceased operations in December 2002 and the January 2003 issue was the last.
Over the years, Radio-Electronics featured audio, radio, television and computer technology. The most notable articles were the TV Typewriter (September 1973) and the Mark-8 computer (July 1974). These two issues are considered milestones in the home computer revolution.

Radio-Electronics was aimed at electronics’ professionals such as radio and TV repairmen. And they were men, the tag line on the cover was “For Men with Ideas in Electronics”.
Radio-Electronics & Electronics Now
Radio Electronics was the “new” name for Radio Craft magazine.. Hugo Gernsback, sometimes called The Father of Science Fiction, started it as Radio-Craft in July 1929. The title was changed to Radio-Electronics in October 1948. In July of 1992 transitioned to “Electronics Now
“I make things, mostly technological, but don’t hold me to that, consistency is not a human virtue. Electronics and software, cast iron and plastics, microcontrollers in vintage automobiles, faux historical machinery that could (not) have been; finely crafted, rigorously rugged, reliable, most often.”
Tom Jennings – World Power Systems
The Model 01a (aka M01a) is a 3″ x 5.5″ self-contained controller board designed for embedded applications. It’s based around Microchip Inc’s in-circuit-programmable 14-bit PICs, and contains I/O expansion, a power supply and various goodies that I found useful in five years of using my previous controller board design.

The M01 board contains enough support hardware to pull off a lot of functionality. Before I get to handling common interface problems here’s a function-by-function description of the hardware. There’s some subtlety to some of the design that’s worth paying attention to.

Yes, there were electric lights powered by central stations before Edison’s! Carbon arc lamps saw extensive use throughout the USA and the world from the late 1870s on. – Charles Brush
Museum Of Electricity – Charles Brush
The General Electric Company was formed in 1892. It was the result of a meger between the Edison General electric Company and the Thomson-Houston Company, which themselves incorporated several other companies.
Electricity, technology, and lots of arcs and sparks!
Museum Of Electricity contains Vintage Electrical and Historical images and description. They include the Edison Lamp, Tesla Coils, Lightning and Atmospheric Electricity and the …..
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.
Nikola Tesla invented the Tesla Coil in the late 1800s. Here you will find some information and technologies related to that. HV is not safe and this is not a Hobby for Youngsters. Read to understand the dangers of High Voltage and Marvel at the phenomena.
The pulse-energy nature of the Tesla coil has long been a tough environment for the discharge capacitor. Coilers have built capacitors with glass bottles and salt-water, sheets of glass and aluminum foil, and more recently, polyethylene sheets, aluminum flashing, and mineral oil
Magnifier Tesla Coil
In a Classic Tesla coil, the magnetic coupling between L1 and L2 is around 20% (0.2). Tesla realized this caused a lot of loss, and he abandoned the design in favor of a 3 coil system with a very high coupling (60%).

“At the age of 10 we moved to Copenhagen for about 2 years. I had some friends there who knew that I liked old radios so regularly someone brought me one. (See my picture at the main page) Among them was the Bang & Olufsen – Grand Prix 48 K (photo). I liked this radio so much that I wanted to make it work again. There was not much wrong so I got it working. Later when we were back in Eindhoven, I made so many …….”

“Back in Eindhoven, there where the 60’s. Radio Luxembourg on my B&O etc. I got interest in guitars and amplifiers. I built several Amps. My first amp was something with the EF11 and the EL3. I also built a copy of the Philips EL6431 Amplifier. (That’s where the output transformer of my B&O radio went) In Eindhoven there was a repair shop called ‘De Radiodokter’. He had some old TV chassis in the display for 5 guilders each. When I had saved enough money, I bought some. Then when I was about 16 I made my first really working TV from these parts.”
History and accomplishments of the General Radio Company, one of America’s first equipment manufacturers for the radio and electronics industry.
General Radio Historical Society
Founded in Cambridge, Massachusetts in 1915, GR provided the tools and instruments that allowed the electronics industry to burgeon into today’s giant that fills our lives with radio, TV, computers, cell phones, DVDs and all the other electronic products in our homes, businesses and automobiles.
General Radio Experimenter
This pioneer publication first appeared in June 1926 and became the model for many others to follow (most notably the HP Journal). It began with engineers talking to radio amateur customers and gradually changed to engineers talking to other engineers, who might also be customers.
GenRad 1863 Megohmmeter
The GenRad 1863 Megohmmeter is the choice for production and inspection tests on devices with resistances up to 20 Tohms.

The 7A42 is 4 channel Plug-in amplifier up to 350 MHz. Conceived for the measurement of logic signals and offers the possibility for triggering the inputs logical AND/OR. So 4 data lines can be observed at the same time on the oscilloscope.
