Solar Power and the Raspberry Pi – 6 Months in the Sun One of the critical subsystems of Project Curacao is the solar power system. The original solar cells have been exposed to the fierce sun for over 6 months. […]
Wind Power and WeatherPiArduino in the Caribbean Wind Power arrives again! Down here in the Caribbean for sun, fun and Project Curacao upgrades. Yesterday, we finished installing the WeatherPiArduino board into the Project Curacao Box and added the WeatherRack sensors to […]
Dead Man Switch The Battery Watch Arduino software has expanded to about 3000 lines of code. Guess what? There are certainly bugs in this software. One of the unresolved issues about the architecture of Project Curacao is that the software […]
Benchmarks: Real Time Clocks – Results for Raspberry Pi/Arduino We recently completed a 3.4 Million Second test run on a Raspberry Pi on three different Real Time Clocks(RTCs). These results are also valid for an Arduino based system. DS3231 PCF8563 MCP79400 […]
MouseAir Version 2 Takes Flight in New Video! The SwitchDoc labs project MouseAir is a bit more whimsical than WeatherArduino,BeaconAir or Project Curacao. This project detects the cat, loads a furry fake mouse in to a launching slot, fires a […]
BeaconAir On Raspberry Pi / iBeacons BeaconAir is a Raspberry Pi based project that reads the advertising packets coming from iBeacons and roughly calculates the physical position of BeaconAir by Trilateration. This is an application that uses the SwitchDoc Labs new iBeacon Python […]
WeatherPiArduino Complete and Ready for the Caribbean Deployment The WeatherPiArduino board is now up and finished. The board to the right of the WeatherPiArduino is a new board called the SwitchDoc Dual WatchDog. It implements an external watchdog function for both […]
Drawing and Displaying Graphs on Raspberry Pi and RasPiConnect using MatPlotLib We often have data that is better shown as a graph rather than a table. It is much easier to pick out a pattern when you show the data visually. […]
iBeacons Review and BeaconAir I just finished the development of a new SwitchDocLabs project, BeaconAir. BeaconAir is a portable Pi device to determine ones position in the house by trilateralation from three iBeacons. The RasPiConnect BeaconAir control panel is below: […]
Real Time Clock Python Libraries For Raspberry Pi – DS1307, DS3231, PCF8563, MCP79400 – Reviews/Results For devices like the Raspberry Pi, a Real Time Clock (RTC) is needed anytime the device is not connected to the Internet (if you care […]
