Low power weather station with BME280 and Moteino

A few weeks ago I wrote about my new door monitor. It was the first step towards migrating my XBee based wireless sensors network to RFM69 radios using Moteino platform by LowPowerLab. I was truly impressed by the low power consumption so I committed myself to keep on working with them.

Coincidentally Felix Russo, the guy behind LowPowerLab, released the new version of it’s Weather Shield for Moteino. So it was time to update (or completely revamp) my trusty Arduino FIO based weather station… and last week I received a parcel from LowPowerLab with a pair of shields to play with: the new WeatherShield R2 and the PowerShield R3. They are both compatible with the Moteino (off course).

Manage and persist settings with Embedis

For months I’ve been searching for a settings manager for my Arduino and ESP8266 projects. There are basically two issues to take care of:

  • On memory settings or how do you access to the configuration values from your code
  • Persistence or how do you store the configuration across reboots

PCB milling

it’s been a while (ok, more than a whole year) since my last post. I could say I’ve been busy and it’d be true but I regret myself not writting here for so long… Anyway if you want to know what I’ve been doing just visit my family blog (only in spanish, sorry).

Blue footed boobies (yes, I know). Nothing to do with this blog but part of our family trip.

My idea now is to revisit old projects, the ones I’ve been working on for the last 18 months and even older, and also to write about new projects I’m involved right now. Good bye chronological order.

The months prior to our travel to South America I was working on some collaborative projects related to Barcelona’s network of public fablabs (named Ateneus), and here I am to share with you one of those projects, not only because I found the initiative interesting and the project worth sharing, but because it was cool to see how a 1.8×3 meters CNC mill (that’s 5.9×9.8 feet working area, for you imperialists) will remove the copper from a 2x3cm clad.

Do you see the copper clad? Me neither, but it’s there…
