This project involved hacking a common Kill-a-Watt power meter to transmit data wirelessly usign an Xbee to my computer (Mac), and then upload the data to two different websites (Pachube.com & Google App Engine) to display graphically…
A much simpler and more useful alternative to plotting with Google is to use Pachube. Pachube allows you to upload your live data and share it with others. Likewise, you can use other people’s data feeds to control something locally or use many feeds to make composite plots, etc. The data is submitted using a fairly simple protocol called Extended Environments Markup Language (EEML) which you can learn about at Pachube.
To upload my data, I used one of the basic python scripts available on ladyada’s site and modified it to send the data tagged in EEML using this python library python-eeml from petervizi. Here is my resulting Pachube data feed and a Flash plot…
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
