Helping Harry’s Heart
Adam Taylor built a remote monitoring system to monitor his dog’s respiration rate to help the vet to adjust his heart medication. They used a X4M200 respiration sensor fitted to Harry’s (the dog) harness. Adam chose to use the free Adafruit IO service to send the dog’s heart rate to, since “along with [the] graphical view, I can also see the time stamped data” to share with “the cardiac specialist at Harry’s next appointment. – Hackster.io
CircuitPython BLE Remote Control On/Off Switch
rdagger has “multiple computers around the house, and sometimes they need to be rebooted remotely.”. Instead of manually opening the locked closet and rebooting their NAS, rdagger opted for a different approach. They built a BLE peripheral which “attaches to the front so the server can be turned on remotely from outside the closet”. – Read the guide on the Adafruit Learning System
Hacking the Sonos Ikea Symfonisk into a High-Quality Amplifier
Ikea released a $99 SONOS-compatible speaker, but a plastic enclosure can’t hold a candle to a pair of high-quality wooden speakers. Ben Hobby grabbed some tools and (literally) hacked one apart to connect it to his bookshelf speakers so you don’t have to. – Read the writeup on Make Magazine.
PyPortal IoT Plant Monitor with AWS IoT and CircuitPython
This smart-planter monitors your plant’s vitals on the PyPortal’s screen, logs data to Amazon AWS IoT, and sends an email to your inbox when your plant needs to be watered! Using Amazon AWS IoT with CircuitPython allows you to prototype internet-of-things projects faster than ever before. With CircuitPython, you’re able to instantly provision your device for AWS IoT by dragging and dropping certificates/keys. – Read the guide on the Adafruit Learning System
Mini Smart Home with Huzzah, HASSio and Crickit
The Mini Smart Home is a test bed that can let you move one step closer to making a truly smart Smart Home. When finished, you will have a completely independent system that hosts a customizable browser based User Interface, a device management system, usage and data logging, advanced automation tools, and user account security. This is all done with a Smart Home server OS called Home Assistant. – Adafruit Learning System

Scientists tracking eagle’s migration patterns rack up roaming charges
Russian scientists tracking the migration patterns of eagles suddenly ran out of money when they found the Eagles were migrating hundreds of miles away to Pakistan and Iran, racking up thousands of dollars of roaming charges. While this is funny – it’s also a scenario one should consider when building mobile IoT projects. – via BBC News
