IoT Chore Reminder for the Serially Forgetful

The secret to domestic bliss often lies in attention to detail, an area in which we can all do a little better. But if paper notes and smartphone reminders are not enough to help you remember to knock jobs off your list, perhaps this IoT task reminder will give you the edge you need to keep the peace at home.

As [Andreas Spiess] points out, his best intentions of scheduling recurring tasks in Google Calendar were not enough to keep him on on top of his share of chores around the house. He found that the notifications popping up on his phone were far too easy to swipe away in favor of other distractions, so he set about building a real-world reminder. His solution uses a WeMOS D1 Mini in a bright blue 3D-printed box with from one to four LED switches on the front. Each box is linked to his Google Calendar, and when a task comes due, its light turns on. Sprinkled about the house near the task, like the laundry room or near the recycling, [Andreas] can’t help but see the reminder, which only goes out when he cancels it by pressing the task button. Simple but effective, and full of potential for other uses too.

Of course, the same thing could be accomplished with a Magic Mirror build, which we’ve seen a lot of over the years. But there’s something about the simplicity of these devices and their proximity to the task that makes sense — sort of like the Amazon Dash concept. We might build a few of these too.

Kindle weather and recycling display

kindle-weather-and-recycling-display

We’ve seen a fair number of hacks like this one that reuse a Kindle basically just for its ePaper display. [HaHaBird] has this device hanging on his refrigerator to display the weather and remind him about recycling day. It kind of make us wonder why we’re not seeing cheap ePaper modules on the hobby market?

The concept isn’t new, but [HaHaBird] does move it along just a little bit. He started by following the guide which [Matt] wrote after pulling off the original Kindle weather display hack. It uses a separate computer running a script that polls the Internet for weather data and generates a vector graphic like the one seen above. The Kindle then loads the image once every five minutes thanks to a cron job on the rooted device. But why stop there? [HaHaBird] tweaked the script to include a reminder about his municipality’s irregular recycling schedule.

Don’t overlook the quality of the hardware side of this hack. With its prominent place in the kitchen he wanted a nicely finished look. This was achieved by building a frame out of cherry and routing passages on the back to make room for the extension cable (so it could hang in landscape orientation) and a toggle to hold the Kindle firmly in place. Additional information on the build is available here.
