Edge computing is here! You've probably heard of this latest entry to the long lineage of tech buzzwords like "IoT," "LoRa," and "cloud" before it, but what is “the edge” and why does it matter? The cloud is impressively powerful but all-the-time connection requires power and connectivity that may not be available. Edge computing handles discrete tasks such as determining if someone said "yes" and responds accordingly. The audio analysis is done at the edge rather than on the web. This...

Polymorph is a non-toxic, biodegradable polyester with a low melting temperature of about 60°C (140°F). Prototype plastic parts can be made by simply heating the plastic beads in hot water until they turn clear and then kneading them together and shaping by hand. When it cools it becomes a nylon-like white plastic. Polymorph can be re-used by simply re-heating and re-shaping. Plastic beads are supplied in a heat-sealed plastic bag to prevent spillage during transport. So what do you do with...

AVR ISP Shield - PTH Kit Description: Did you know that your Arduino can spawn other Arduinos? Don't worry, it can't do it autonomously so you won't wind up with a replicator situation (-gate, not -Trek). The point is, the ArduinoISP sketch allows your Arduino to act as a programmer. You can use this awesome power to burn bootloaders onto ATMega chips, turning them into Arduino-compatible microcontrollers! In the past, this required a breadboard and a whole mess...

This is your tried and true white solderless breadboard. It has 2 power buses, 10 columns, and 30 rows - a total of 400 tie in points. All pins are spaced by a standard 0.1". The two sets of five...

This is your tried and true white solderless breadboard. It has 2 power buses, 10 columns, and 30 rows - a total of 400 tie in points. All pins are spaced by a standard 0.1". The two sets of five columns are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 29-20AWG. This board also has a self-adhesive on the back. The boards also have interlocking parts, so you can hook as many together as you'd like. Dimensions: 3.29 x 2.15 x...

The US1881 is an integrated Hall-Effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage,...
