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. ... - 4

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. - 7
MFJ-993b Web Remote
Arduino Mega 2560 + Ethernet Shield to Drive 8 Relays for MFJ-993b
Arduino Mega 2560 Code to that supports a standard Ethernet Shield . i.e. Drive Relays hence outputs to MFJ-993b. Supports Up and Down for manual L and C Tuning, Autotune On/Off, Antenna Selection 1/2 and 100ms Short /1000ms Long for Tune. Op Note 1: You may need additional power for the 5V relay board; sometimes you can power the 5V relay board from the Mega 2560 - but reset/start the device first and then connect power to the relay board. Op Note 2: You will need determine pinouts to the MFJ-993b DB9 yourself. ... - 8
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. - 9

AntennaTuner
A remote symetric antenna tuner using switched relays.
This is project about DL3LAC's Antenna Tuner called "Christian-Koppler". The original tuner used an semidigital remote controller and 24line cable between the tuner unit and remote controller. I decided me to build the tuner unit and replaced the controller part by an ATmega MCU on both sides and linked them with cheap network cable. The used protocol between the controllers are RS422 based and is frame based with checksum. - 17
