Tapplock One+ is a Fingerprint-Based Lock

· · Cool Stuff Found

Tapplock came out with a new product called the Tapplock one+. It features 7mm reinforced stainless steel shackles, strengthened by double-layered lock design with anti-shim and anti-pry technologies, making it the ultimate utility fingerprint padlock. Plus, a state-of-the-art capacitive fingerprint sensor allows unlocking in under 0.8 seconds. Its adaptive algorithm means the lock becomes faster and more accurate with each access. You can store up to 500 different fingerprints per lock, and manage users and fingerprints via the Tapplock app. There are three ways to unlock: fingerprint, Bluetooth, and Morse code. The battery lasts up to a year or 3,500 unlocks. You can get a single Tapplock one+ for US$99, a double pack for US$179, and a four-pack for US$359.

These Algorithms Can Create Efficient Floor Plans

I’m always fascinated by a computer’s approach to human problems and experiences, because it usually ends up being something completely alien to us. Evolving Floor Plans is an experimental research project that I came across the other day. Using genetic algorithms, an optimized floor plan was created for a school.

The floor plan genome is a weighted, connected and undirected graph. Every desired room is represented with a node gene that contains information such as the room’s size. Connection genes specify two node genes to span as well as a randomly initialized weight; they are added in a random manner until the graph is connected. Adjacency requirements create a subgraph with maximum edge weight. For example, the cafeteria must be adjacent to the kitchen.

It’s neat that the optimization creates a building that looks like a biological cell. I’d love to see more examples, like an optimized apartment building or house with multiple floors.
