The Big Electronic Human Energized Machine, Only Too Heavy (BEHEMOTH) [1] was an electronic bike weighing in at roughly 450 pounds. It was created by a multi-disciplinary team of volunteers led by Steve Roberts, a self-taught computer hobbyist.
The BEHEMOTH took three and a half years to build and it involved teams of engineers, machinists, bicycle experts, and chip-makers working in labs and shops across California including Palo Alto, Milpitas, Santa Cruz, Soquel, Scotts Valley, and Mountain View. There were many technologies that were used in this project including but not limited to fiber-glassing, sheet-metal fabrication, machining, FORTH software programming, harsh-environment packaging, networking, power management, embedded systems and audio processing. According to Roberts, the BEHEMOTH was to be a "collection of all the geeky tools that he could imagine, integrated into a limited user interface available while pedaling a bicycle". [2] He envisioned a project where "computer and communication tools rendered physical location irrelevant." [3]
The BEHEMOTH logged over 17,000 miles while in service and demonstrated the integration of technologies for recreational use as a visible artifact of early wireless mobile networking.[ citation needed ] The BEHEMOTH was donated to the Computer History Museum, where it's currently on display. [4]
The BEHEMOTH bike contained many of the latest technologies of the time[ when? ] which were packed within the following three main equipment enclosures:
The console consisted of the following technologies: [2]
The RUMP consisted of the following technologies: [2]
The trailer consisted of the following technologies: [2]
In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. The term is also used for other devices which can both transmit and receive through a communications channel, such as optical transceivers which transmit and receive light in optical fiber systems, and bus transceivers which transmit and receive digital data in computer data buses.
A music sequencer is a device or application software that can record, edit, or play back music, by handling note and performance information in several forms, typically CV/Gate, MIDI, or Open Sound Control, and possibly audio and automation data for digital audio workstations (DAWs) and plug-ins.
A walkie-talkie, more formally known as a handheld transceiver (HT), is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
A mobile data terminal (MDT) or mobile digital computer (MDC) is a computerized device used in emergency services, public transport, taxicabs, package delivery, roadside assistance, and logistics, among other fields, to communicate with a central dispatcher. They are also used to display mapping and information relevant to the tasks and actions performed by the vehicle such as CAD drawings, diagrams and safety information.
A digital audio workstation is an electronic device or application software used for recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece.
Base station is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a "land station in the land mobile service."
Van Eck phreaking, also known as Van Eck radiation, is a form of eavesdropping in which special equipment is used to pick up side-band electromagnetic emissions from electronic devices that correlate to hidden signals or data to recreate these signals or data to spy on the electronic device. Side-band electromagnetic radiation emissions are present in keyboards, computer displays, printers, and other electronic devices.
A base transceiver station (BTS) or a baseband unit is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers. The network can be that of any of the wireless communication technologies like GSM, CDMA, wireless local loop, Wi-Fi, WiMAX or other wide area network (WAN) technology.
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers, speakers, headphones, projectors, GPS devices, optical mark readers, and braille readers.
An electronic game is a game that uses electronics to create an interactive system with which a player can play. Video games are the most common form today, and for this reason the two terms are often used interchangeably. There are other common forms of electronic game including handheld electronic games, standalone systems, and exclusively non-visual products.
Electronic media are media that use electronics or electromechanical means for the audience to access the content. This is in contrast to static media, which today are most often created digitally, but do not require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media. However, electronic media may be in either analogue electronics data or digital electronic data format.
FÉLIN is the name for the French infantry combat system developed by Safran Electronics & Defense.
The sport of amateur radio contesting has been responsible for the development of contesting technology specific to the sport. The most competitive stations participating in contests employ new and innovative technology, hardware, and software. Some of these innovations are exclusively used in the sport of contesting; others have seen wider application in amateur radio at large.
An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries.
D-STAR is a digital voice and data protocol specification for amateur radio. The system was developed in the late 1990s by the Japan Amateur Radio League and uses minimum-shift keying in its packet-based standard. There are other digital modes that have been adapted for use by amateurs, but D-STAR was the first that was designed specifically for amateur radio.
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They are received by another antenna connected to a radio receiver. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications.
MiWi is a proprietary wireless protocol supporting peer-to-peer, star network connectivity. It was designed by Microchip Technology. MiWi uses small, low-power digital radios based on the IEEE 802.15.4 standard, and is designed for low-power, cost-constrained networks, such as industrial monitoring and control, home and building automation, remote control, wireless sensors, lighting control, and automated meter reading.
The ICOM IC-7100 is a multimode HF/VHF/UHF mobile amateur radio transceiver. The IC-7100 has support for a wide variety of commonly used amateur radio modes including ICOMs proprietary digital voice mode DSTAR. Additionally the radio offers 100 watts on HF, 50 watts on VHF, and 35 watts on UHF. The IC-7100 is unique in that it has a large detachable control head with a slanted display so the transmitter can be installed elsewhere in a vehicle or home. The receiver used in the IC-7100 is a triple conversion superheterodyne and has excellent DSP and audio filters. The IC-7100 allows for connection to a computer over USB which enables the radio to be used for popular digital modes such as FT8, Winlink, and Packet Operation. Locations of nearby repeaters and sending APRS locations can be done with an optional GPS receiver attachment. Notable features that the IC-7100 lacks is an internal antenna tuner.
Steven K. Roberts is an American journalist, writer, cyclist, archivist, and explorer. He first gained public attention as a pioneering digital nomad, before the term became widely used, when from 1983 to 1991 he rode his computerized bicycle, a modified Avatar 2000, pulling a trailer with solar panels and a laptop across the United States of America. His book, Computing Across America, documents his journey.
