I found this nice series of lessons on Python and Arduino interaction. These lessons cover topics ranging from installation of Python and Arduino libraries to connecting sensors and wireless communication.

Matthew Venn has designed a prototype energy wristband that would tell you when there is a change in electrical energy usage at home through a a gentle vibration. The wristband also consists of a 4-LED bargraph to display the current usage. A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a ‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4. Realtime energy use can be queried by pressing the button.

Marc Jensen, James Squires, and Shawn Roske over Make have posted great instructions on making an Apple watch door unlocker using RFduino, which can unlock your front door with just a tap on an app. We started this project to help solve a real-world problem: prevent our employees from being locked out of our office. Our security system automatically locks the doors outside of normal business hours. If someone steps out of the office without their security card or keyfob, they’re locked out. When this happens, people use their phone to call or email people at the office to let them

IngGaro‘s entry to the 2015 Hackaday’s Prize contest is an Arduino Alarm Shield that supports NFC and RFID activation with authorization control and can turn an Arduino Mega 2560 board into an anti-theft alarm system.The system is capable of sending email and GSM notifications and can be fully configured through a web interface. The system is composed by a main circuit (the arduino shield) installed in an hidden place and an i2c connected “remote control panel” near the main house door, offering LCD, capacitive buttons and RFID recognition. The whole system may be managed and configured from the webserver; webpages are published

Pete Mills’ has shared his cool-looking DIY Nixie clock design on his personal blog. His design is based on Atmega328 and uses software driven RTC and voltage booster to achieve ~175V DC for Nixie tubes. Nixie tubes are cool. They have great aesthetic appeal with their difficult-to-photograph, warm orange glow, and dem curvy numerals. They add an organic je ne sais quoi to a hobby with ostensibly digital design cues. Further, they pose technical challenges in the way of producing and switching the ~175 V DC needed to light each tube element. And as far as I am aware, there are
