channel3
ESP8266 Analog Broadcast Television Interface
Channel3 is an experimental ESP8266 project that generates analog television signals directly from a microcontroller GPIO pin. It uses the ESP8266 I2S peripheral at an 80 MHz bit rate and DMA buffers to synthesize radio-frequency waveforms. An antenna connected to the output can transmit a signal receivable by an analog television tuned to Channel 3. The implementation produces luma and color information through carefully constructed one-bit modulation patterns. Several demonstration screens show text, graphics, color swatches, lines, and simple 3D scenes. A browser interface lets users select demos and experiment with generated modulation patterns. ... -

WSPR Scheduler
WSPR Scheduling application with automatic antenna selection
...There are four main tools currently available within the WSPR Scheduler suite of apps: 1) the WSPR Scheduler includes encoding software to transmit a WSPR signal within each timeslot & a decoder to receive & display received WSPR transmissions. Frequency selection is automatic. Antenna selection can also be automated by automatic switching according to the antenna configured for each timeslot. Operation of an auto tuner is also possible. 2) WSPR live reporter. This links to wspr.live to retrieve reports of own station WSPR transmissions from receiving stations. 3) WSPR Map - displays the reported transmissions on a World map to show the location of WSPR reports, 4) WSPR Solar - this retrieves solar geomagnetic data from NOAA & the GOES satellites. ... -

wxlls
WxLLS is a single station lightning location system.
WxLLS provides hardware, software, and scientific content for building a single station lightning location system. The azimuth to the strike location is determined using an orthogonal magnetic loop antenna. The distance to the strike is determined using various properties of the vertical electric field with the vertical electric field being sensed by a parallel plate antenna. The type of lightning strike, CG versus NonCG, is determined by using various properties of the electric and magnetic fields. Research continues on improving the distance accuracy, however, the direction is very accurate. ... -

Minimal-GPSDO
A GPSDO with superior performance using a few cheap components
...) ● Be self monitoring so the accuracy can be guaranteed without reference to a better standard ● Require no tuning by the user ● Give feedback to the user of the current status ● If it can be done in software, do it in software The initial design consisted of a U-blox NEO-6M GPS receiver with active antenna, a PIC16F1455 microprocessor, a 74HC04 buffer powered by a 5V wall wart. This achieved the criteria. The current design is the same with a more elaborate power supply. It is more stable than the original, and regularly delivers better than 10MHz±1mHz. -

ShiftRC
Simple cheap DIY RC receiver/handler.
...this project will host multiple version, some very simple ones, and some more complex. a similar thing can be said for the controllers, I will soon upload the schematics and designs for a steampunk style controller. but for a more simple understanding a simple remote might be a transmitter(led, speaker, or antenna for example) a button, and a capacitor to stabilize the button because every pulse you send changes the state. however high precission control is possible. Use the project and schematics however you want it as long as it does NOT restrict others. -
