Computing stuff tied to the physical world

Who needs a server?

With all those energy pulses flying through the air, we don’t even need a central setup to display this information on a little self-contained Graphics Board display – like so:

The “homeGraph.ino” sketch which drives it has just been added to GitHub:

There’s room for a little graph, but it’ll have to wait until the home usage counter has been rewired to measure the proper value (the value shown above is in fact the surplus).

  1. Nice :) The picture also suggests that you have solved the wireless power problem ;)

  2. Just what I was planning to make. I even have the enclosure ready. Different payload for me, but your example is a great start… Thanks.

  3. Good job, I even made my own PCB that better fits the GLCD and you could even log data to the SD card for later use.

  4. I’ve also found a lithium battery from a phone that’s similar size to the GLCD and it powers the whole thing for about a week, I’m sure I can extend that a bit more though.
