Get Up Close to your Soldering with a Pi Zero Microscope

Do your Mark 1 Eyeballs no longer hold their own when it comes to fine work close up? Soldering can be a literal pain under such conditions, and even for the Elf-eyed among us, dealing with pads at a 0.4-mm pitch is probably best tackled with a little optical assistance. When the times comes for a little help, consider building a soldering microscope from a Pi Zero and a few bits and bobs from around the shop. Affordable commercial soldering…

Look at me with your Special Animatronic Eyes

Animatronics for movies is often about making something that works and is reliable in the short term. It doesn’t have to be pretty, it doesn’t have to last forever.

Hi, hope someone can chime in on this. This resistor http://imgur.com/a/X7uhR came from a Makita battery charger for a drill. Obviously it's released its magic pixie juice and it gotten a bit discoloured in the process. I feel like it should be a 10k 1% resistor but I'm not sure if I'm reading it all wrong. It measures about 133 ohm at the moment, out of circuit, not sure if that's due to failure or not. Also I reckon it's…

The Lake Erie Mamba is a 12-servo snake robot

If you want to build a robot that moves across the ground, the normal options are wheels or legs of some kind. Maker “joesinstructables,” however, decided to do something a bit different. He created a versatile, slithering system, which he calls the “Lake Erie Mamba.” He put a dozen Arduino Mega-controlled servos together in a reptile configuration to allow […]

Scare your friends with a 3D-printed animatronic eyeball

With October still six months away, you may not be thinking about Halloween decorations just yet. However, this Arduino-based ocular assembly could make for a spooky yet simple prop! There are few things more unnerving than an eyeball or three looking at you from some concealed position—such as under clothing as in the project’s video. If […]

Teenage Maker builds his own Arduino drone

When most people decide they’re going to build a quadcopter, they likely go to their favorite online retailer or hobby shop, and get the correct parts to connect together. 17-year-old Maker Nikodem Bartnik instead decided to customize things further, programming an Arduino to act as his flight controller, and constructing a transmitter (or “pilot” as he refers to it) […]

IoTuesday: DIY IoT LED Weather Visualizer

A few weeks ago, my coworker Blake approached me with the idea of building a weather visualizer inspired by the beautiful Rocky Mountains. The idea was to make an indoor visual display that would imitate the look and feel of the current weather outside. Blake had a strong idea of how the project should look. He stained reclaimed wood different colors to build a mountain scene based on the view from our office. Then he handed it…

Getting started with the micro:bit - Making a temperature gauge

As we continue with the micro:bit series, we look at another onboard feature: the temperature sensor. Interestingly, there is no separate chip for the temperature sensor. Instead, we read from the temperature sensor built into the main processor (nRF51822). While it was originally intended for detecting overheating, we can use it to get an idea of the ambient temperature (just make sure you’re not taxing the processor, as you’ll…

Qwiic Human Presence Sensor - AK9752 (SPX-14289)

This is not your normal PIR! The Qwiic Human Presence Sensor - AK9750 is a passive infrared sensor with four discrete sensors built into one digital package. PIRs are most often used in security systems to detect the movement of a human talking through the room. If you’ve ever seen a 1" white sphere in the corner of a room, that’s a PIR. We sell a simple PIR as well but the AK9750 is far more advanced. The AK9750 is a digital…

Qwiic Mux - PCA9548A (SPX-14293)

The Qwiic Mux - PCA9548A enables communication with multiple I2C devices that have the same address and between different bus voltages (2.8V, 3.3V, and 5V). The PCA9548A is a very easy to use I2C multiplexer enabling up to 8 buses. This means you can communicate with 8 of the same device or mix and match between 5V, 3.3V and 2.8V devices. The PCA9548A can be daisy chained as well, so, if needed, you can use up to eight of the shields at the same…

The MLX90393 is a tri-axial magnetic sensor capable of sensing very small fields (like the Earth’s magnetic field) while behaving as one would want and expect during saturation in larger fields (like a near by magnet). It turns out the favorite HMC5883L and other such sensors that are intended for compass applications have a low dynamic range but also strange and undefined behavior in large fields.
