One of the worst things about sewing is finding out that your bobbin — that’s the smaller spool that works together with the needle and the larger spool to make a complete stitch — ran out of thread several stitches ago. If you’re lucky, the machine has a viewing window on the bobbin so you […]

The finger-tip sized ARM Cortex-M4F module with BT 5, BT Mesh, and 30 I/O The arrival of Bluetooth 5 was a significant leap forward for the IoT developer community, especially with its new Bluetooth Mesh functionality, which connects more devices and more sensors. Nearly four billion devices are expected to be shipped with Bluetooth technology

[Harrison] has been busy finding the sweeter side of quarantine by building a voice-controlled, face-tracking M&M launcher. Not only does this carefully-designed candy launcher have control over the angle, direction, and velocity of its ammunition, it also locates and locks on to targets by itself. Here comes the science: [Harrison] tricked Alexa into thinking the Raspberry

[Engineer2you] built a nixie tube clock and claims it is the simplest design. We felt like that was a challenge. In this design, the tubes are set up as a matrix with optoisolators on each row and column. With 60 segments, the matrix allows you to control it all with 16 bits. There are six columns, each

I’d like to share my latest project, a scanning laser microscope with you. Some words concerning the principle: The pinciple is quite simple. The laser beam is focused on the object and the reflective light is being measured with a photodiode (in my case a BPW34). To focus right the current through the focusing coil

Adafruit is now offering an assembled DC Motor + Stepper FeatherWing add-on board priced at $21.50 enabling you to use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors) with the companies FeatherWing range of controllers. Since the FeatherWing only uses the I2C (SDA & SCL

The computers we are used to working with are more likely to be at the smaller end of the computational spectrum. Sometimes they are very small indeed, such as tiny microcontrollers with only a few GPIOs. Others are single board machines such as a Raspberry Pi or an Arduino, and often a desktop or laptop

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, which is decidedly more off-road than America’s Power Racing Series. In pushing these little electric vehicles to the limits, many builders

In this tutorial, we will show you how to control DC motor using MATLB and Arduino. If you are new with MATLAB then it is recommend to get started with simple LED blink program with MATLAB. Creating MATLAB Graphical User Interface for controlling DC Motor After finishing setup with Arduino for MATLAB, we have to build GUI

Building stuff and getting them work, the way we want, has always been sheer fun. While that being agreed, building stuff that could fly would defiantly pump a bit more anxiety among the hobbyists and hardware tinkerers. Yes! I am talking about Gliders, Helicopters, Planes and mainly multi-copters. Today it has become very easy to
