IP Time Clock using NTP protocol
https://www.electronics-lab.com/ip-time-clock-using-ntp-protocol/
by msuzuki777 @ www.instructables.com So this Lazy Old Geek (LOG) has a couple of clocks in my bedroom. One of them loses time when the power is lost. The other is semi smart and automatically adjusts for Daylight Savings Time. Unfortunately, it does this using the old standard so I have to re-set the time four […]
Hacking a Blood Pressure Monitor
https://www.electronics-lab.com/hacking-a-blood-pressure-monitor/
by Eduardo @ edusteinhorst.com: I’ve been meaning to hack my blood pressure monitor for a while, and I finally got around to doing it! So, the idea is to mod a regular electronic blood pressure monitor to make it wireless and connected to the Internet, much like iHealth BP5 or Withings’. That makes detecting trends in your […]
Arduino based MPPT solar charge controller
https://www.electronics-lab.com/arduino-based-mppt-solar-charge-controller/
by Abid Jamal @ electronicslovers.com: what is Mppt( Maximum power point tracking) ? “we use MPPT algorithm to get the maximum available power from the Photovoltaic module under certain conditions” How MPPT works ? Why 150W solar panel does not equal to 150 w? For example you bought a new solar panel from the market which puts […]
