BLE-based Crowd Indicator for Small Stores


Smaller shops may not be able to hire extra employees to enforce or monitor social distancing. This solution by Ian Mercer tracks every Bluetooth Low Energy (BLE) device nearby to figure out when the store is busy. - Hackster

PyPortal Home Office Busy Display


Diana Perkins (@diana_perkins) built a display using a PyPortal to show when someone in their home offices is busy. It’s controlled using a “rails app running on a machine on our local network so we can trigger it even if we already sat down for a meeting” - Twitter

Mesh WiFi Music-Reactive Light System


GlowFly is a WiFi connected, programmable and music reactive light system. When multiple nodes are combined, it is possible to span a mesh of WiFi connected devices which are synchronously reacting to music. - HackaDay

Aquarium automation system using a Feather nRF52840 and four extra FeatherWings. There’s an automatic fish-feeder and Raspbery Pi based fishpi monitors for temperature and lights. Scripts used in this project are open-source and on GitHub -Twitter

This Blog is Now Running on Solar Power


Lou Wrentius’ blog is now running on one solar panel and an old car battery. There’s a solar panel on his balcony “which is connected to a solar charge controller”. Clicking through to their blog, you can see a sidebar which shows the solar panel’s status. This widget runs on the same solar-powered Raspberry Pi which hosts the blog. If the weather is favorable, “the solar panel provides way more power than is required to keep the battery charged and run the Raspberry Pi”. -louwrentius

Dawn and Dusk Porch Lights


WiFi-enabled Wemo switch to turn off a porch-light at dawn and dusk. This switch includes an intelligent scheduler which obtains the location-specific sunset and sunrise times from the internet. - HackaDay

Adafruit IO Update: New Trigger Functionality

AIO Trigger Update

The Adafruit IO team has released some changes to Adafruit IO, our easy-to-use-internet of things platform. First is an update to Scheduled Triggers. Scheduled triggers now have a much more robust option to scheduling. If you’re familiar with cron scheduling, you’ll be familiar with this new system. You can schedule based on a number of new time and date options.

We’ve also added the ability for reactive triggers to email a value based on the feed that is being acted on, or now you can also update the value of any of your feeds from that trigger. For example, if the ‘humidity’ in your house is > 50%, you could update another, ‘dehumidifier’ feed to set the value to “ON”.

Finally, we’ve made further system changes that should improve the performance of Adafruit IO for all users.

Support Adafruit


Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
