12ft GPS Wall Clock
A discussion was held regarding the creation of a 6-foot tall alarm clock, modeled after a Timex faceplate. Initially perceived as an impractical idea, the project faced challenges that led to its suspension. However, the discovery of pre-packaged LED light...
The R2 Single Sideband Direct Conversion Receiver
The old common-base audio preamp, which has a noise figure of 5 dB, is a clear candidate for improvement in noise performance. A common-emitter configuration with shunt feedback provides an input resistance of 50 ohms, which is preferred by the...
loop antennas
A loop antenna is a radio antenna made up of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. This design includes two distinct types of antennas: the small...
gps altimeter
This device was developed rapidly for the USC Rocket Propulsion Lab, which is a student-run high-altitude rocketry initiative at USC. It was assembled shortly before the launch and programmed during travel to the launch site. The device utilizes a Picaxe...
6-17 MHz SW reciever
Its very simple as It uses only 3 transistors 2n2222. The Coils can be altered to change the range of reception by lowering or highering the frequency. More: This circuit is a SW band receiver of range 6 to 17...
1.57-GHz Front-End for GPS Receiver
The GPS is based on 24 satellites located in six orbital planes at a height of 20,200 km and circle the Earth every 12 h. Each plane is inclined at 55 to the Earth’s equator and contains four satellites. The...
Four Foot Box Loop Antenna
Please find attached your copy of my four foot unamplified box loop. It will tune from 525 kHz to about 1710 kHz covering the entire Broadcast Band. The umbrella stand described in the article is the type you would use...
