The Homebrew Computer Club was an informal group of electronic enthusiasts and technically minded hobbyists who gathered to trade parts, circuits, and information pertaining to DIY construction of personal computing devices. [3] [self-published source] It was started by Gordon French and Fred Moore who met at the Community Computer Center in ...
Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]
A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; [1] these elements are most often metal rods (or discs) acting as half-wave dipoles. [2]
However, a Yagi with the same number of elements as a log-periodic would have far higher gain, as all of those elements are improving the gain of a single driven element. In its use as a television antenna, it was common to combine a log-periodic design for VHF with a Yagi for UHF, with both halves being roughly equal in size.
Federmeyer used the term homebrew to describe hobbyist-driven development, inspired by the California Homebrew Computer Club of the 1970s. [14] After designing the cartridge for his own use, Federmeyer advertised it on Usenet, [15] followed by an unlicensed version of Tetris. [13] Since then, over 100 games have been released, [16] many ...
A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix.A helical antenna made of one helical wire, the most common type, is called monofilar, while antennas with two or four wires in a helix are called bifilar, or quadrifilar, respectively.
The Vectrex synchronizes the rotation of the disk to the software frame rate as it draws 6 screens: with the right eye covered: the left eye red image, then green, and then the blue image is drawn, and then, while the left eye is covered by the black 180-degree sector: the right eye red, green, and then the blue image is drawn.
An altered AWX antenna which had been designed and built by an amateur radio operator and has been used by the amateur radio station. An AWX antenna is an antenna which means that it can be used for All Wave radio frequency and is shaped like X.
