    Many coffee lovers spend up to 5onacupofcoffeeeveryday.Tosavemoneyonecouldmakethemathome,butaqualitymachinewithPIDsstartat5 on a cup of coffee everyday. To save money one could make them at home, but a quality machine with PIDs start at 1000. Using an embedded system one could spend less than 50andafewhoursimplementPIDsintoanexisting50 and a few hours implement PIDs into an existing 400 machine that will last a lifetime. microcontroller. Learning C language combined with hardware implementation applied to cheap and simple everyday objects can improve everyday quality of life and save money. This is challenging because we have to incorporate the additional circuitry into a pre established circuit with limited space, and tie in new code. In addition to the PID controls that are commonly found on high-end espresso machines, Our team decided to implement a touch screen interface, which required programming using a proprietary IDE and language. The resulting product is able to match temperature and pressure consistency levels that are found in competing machines. When we added in programmability of pre-infusion we start to compete with machines in the $5000 range, like the La Marzocco GS3, but we go even further with a touch screen interface, and the ability to plot temperature and pressure over time on the included LCD screen

    The 16th Data Release of the Sloan Digital Sky Surveys : First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra

    This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17).Peer reviewe
