...Some of these sensors are supposed to be more accurate than others, which may be true, and some are supposed to be faster at data acquisition than others, which is definitely true. I decided to compare sensors using a Raspberry Pi 3 for sensor control and data acquisition and a fairly powerful laptop running R to do the analysis.
This Instructable explains how I built WiFi enabled thermostats for my home. The thermostats are programmable with 6 different time periods during the day, although increasing that to any arbitrary number would be fairly trivial. They can be programmed (in the sense of setting times and temperatures) as well as controlled over the internet, and they have a touchscreen LCD display for local control as well.
Depending on current location, elevation, and velocity we all experience very real time dilation effects. Time does not pass at the same rate for everyone. The "Project GREAT" experiment in 2005 measured a 20 to 30 ns shift during a weekend family trip to Mt Rainier.

This is my arduino-based waveform generator using a 8-bit resistor ladder DAC. It runs with a sampling rate of 65536 Hz and can create any (whole-number) frequency from 1 Hz to 30ish KHz in sine-wave, sawtooth, triangle and different ratios of square wave.
Build a unique personalised gift that’s cool and reflects the character of the recipient.What’s different about this Word Clock is that it is small enough to sit on a bedside desk, displays the recipients name and has personalised messages that appear at different times ie. Happy Birthday, Carpe Diem, Good Morning or whatever you choose.Great for people of all ages who enjoy something a little unique.Please note: This a variation of the traditional word clock design. Credit must be given to the guys who came up with the original design. In particular these two instructables provided inspiration for this projecthttp://www.instructables.com/id/The-Word-Clock-Arduino-version/http://www.instructables.com/id/Javelins-Word-Clock/
Whether you are just beginning or have extensive experience with Arduino, there is something here for everyone.In the Electronics Lab, you can prototype and design before you build a circuit in real life.
These Low Cost Easily Programmable Circuit Boards can be Used for Projects in Many Academic Subject Areas I’m looking to share stories about teacher and student uses of these relatively inexpensive gadgets in their classrooms.
