“The huge increase of portable devices during the last 10-15 years has lead to numerous companies seeking (and succeeding) to make significant profits in this market. Many consumer applications are now powered by accumulators, ranging from the omnipresent cellular phones …
“There are applications that require loose output regulation and current less than 20mA. For such applications, a linear regulator built with discrete components is a cost-effective solution (Figure 1). For applications with tight output regulation and requires more current, a …
“This Instructable is for making a programmable Pumpkin light with an ATTiny microcontroller. This was designed as a learning demo to introduce anyone (age 8+) into electronics and programming microcontrollers using the Arduino IDE.”
“Here is my version of the Raspberry Pi arcade coffee table. I got the idea from other great instructables on here and wanted to share my experience with the build. The table can play games from multiple video game eras …
“Create your own rc controlled led-strip for individual room illumination! Most rgb-led-strips are controlled by an infrared remote control. To turn it off or on or change the color, you have to stay in front of the receiver. This is …
“AN6877 is linear AF level meter IC produced by Panasonic and it is commonly found on many audio equipment. This chip is no longer manufactured by Panasonic and finding replacement chip for AN6877 is also quiet difficult. The circuit described …
“This innovation comes from the hand movements that can controll a robot. In this project i use flex sensor and i am taking the flex sensor reading and putting this reading on to the intel edison. as a analog value …
“This is my 2nd Instructable and my 2nd Arduino powered CNC, this time around I up the difficulty level by deciding to make a self contained CNC unit by design my own electronics enclosures and placements. The steps of this …
“This circuit sets up the common 555 timer IC to output a PWM pulse that can be varied by the position of a connected potentiometer. PWM (pulse width modulation) is commonly used to control the speed of motors or brightness …
“After several projects with PIC24 generating plain VGA signal, I managed to support the sprites in the real time. That gave me the idea to make the 2D video game, and my choice was the old Spectrum’s game “Jumping …
