An RC aircraft can be expensive. If you plan to chase other RC aircraft on a path of mutual destruction, keep costs down with a disposable flying platform.

I had the idea of creating a night flyer out of one of my R/C combat planes. What if it could be done quickly using servo leads and be easily serviceable?

Radio-Controlled onboard power systems used to be quite basic, but with the introduction of electric drive motors and other power demands, things have changed.

Find out how to transition your facility from a reactive to a predictive maintenance protocol in this webinar.

How to use a series of capacitors and resistors to convert a square wave to a sine-like wave that results in a comfortable audio signal that sounds natural.

What are flip-flops and how do they work? Find out in this blog.

A working example of how RC timing functions in a DC circuit.

The founder of DigiKey started the company by selling a Morse code generator. See its original design alongside an updated version you can build.

Hydraulic and pneumatic actuators offer power and speed in repetitive use mechanisms. Each type offers distinct advantages and features.

Covering all combinations of button presses with if/then statements could generate hundreds of lines of code. Implementing bitwise logic minimizes code.

Make a custom breakout board for FadeCandy using DigiKey’s PCB Builder tool.

Mainstay 5 V logic is joined by ever lower voltage standards like 3.3 V, 2.5 V, 1.8 V and lower, resulting in the need for mismatched systems to communicate.

On Nikola Tesla’s birthday (July 10th) we remember his accomplishments and drive, especially towards wireless power.

Preventive maintenance is a common methodology intended to prevent legacy machine down-time, but it can come at great cost. Omron has solutions to reduce cost.

Digital panel meters are available in LED or LCD configurations with a wide array of text colors and backlighting if needed.

When a project’s physical size goes beyond using traditional project boxes and enclosures, custom extruded aluminum frames could be a good choice.

The benefits of logic and small signal switching using MOSFETs over other traditional transistor technologies.

As programming becomes more accessible to the masses, some basic but valuable bits of code may be forgotten such as direct port manipulation.

The SparkFun Teensy 3.5 has enough digital interrupts to handle three brushless DC (BLDC) hall sensor signal inputs and route display data where needed.

The Digilent AD2 can help in visualizing the output of hall effect sensors to aid in understanding and processing signals during project development.
