Dr. Phys. Eugen Pavel, Inventor of Hyper CD-ROM (Petabyte Optical Disc)

Reading time: 3 minute Dr. Phys. Eugen Pavel, from the Institute of Atomic Physics in Magurele, made a CD (Compact Disk), made of glass, with a storage capacity 15000 times higher compared to an ordinary one. In November 1999, his invention was awarded the gold medal at the "Brussels Europa" World Invention Fair. In the same year, the author wanted at any cost the serial production of this CD in Romania.

Pivetta Opera Only - Perhaps the most expensive audio amplifier in the world

Reading time: 2 minute With a height of over 2 m, a weight of 1500 kg and an impressive design, it looks more like a futuristic teleportation device than a power amplifier. Its beauty is matched only by specifications. In the construction of this applicator, some more special materials were used, such as: aeronautical quality aluminum and gold.

Bletchley Park - UK Cryptanalysis in WWII

Reading time: 3 minute During World War II, Bletchley Park was the headquarters of the UK's leading cryptanalysis organization. The codes and figures of several Axis states were deciphered here, the most important being the German Enigma and Lorenz cars, owned by the Government Code and Cypher School (GC&CS), which regularly entered the Axis Powers' secret communications.

Technical bulletin - Electronica Bucuresti Nr.10 - Televisions with 4 integrated circuits

Reading time: 2 minute The color TV that was to be manufactured at Electronica in 1983 consumes less than 100W from the mains and works freely at mains voltages between 150V and 250V. In this way, the design ensures that an essential task for the national economy and for the remote owner is achieved: energy saving.

EFD108 - The most used germanium diode in Romania (IPRS Baneasa)

Reading time: 3 minute Point diodes (like EFD108) can be considered the "ancestors" of Schottky diodes. They used to be called "Schottky microdiodes with germanium". Although constructive differs a lot, the operation is very close, the opening threshold is lower than the PN junction diodes with germanium (approx. 0.2V) and they do not have that "steep bend" in the opening area of ​​the junction diodes.

What are ICE (In Circuit Emulators) and how do they work?

What are ICE (In Circuit Emulators) and how do they work?

Reading time: 5 minute The emulator is a high-performance solution for developing microcontroller applications. If in electronics without microcontrollers the oscilloscope is used, in applications with microcontrollers the circuit emulators are also used. It is the most efficient way to see what is happening inside the microcontroller.
