“This article explains to connect an Optocoupler System. This system is used to isolate the two power sources. Typical applications include medical where the patient needs to be isolated from possible power supply faults and surges to avoid electric shocks …
“This is a guide for creating a simple sequencer. A sequencer is a device that cyclically produces a series of steps that then drive an oscillator. Each step can be assigned to a different tone and thus create interesting sequences …
“The project presented here is a photodiode amplifier for visible light. The output voltage of the circuit increases linearly with light intensity. Low-cost BPW34 photodiode is used as a light sensor and OPA381 op-amp as an amplifier. OPA381 is a …
“The Intel 8086 microprocessor is one of the most influential chips ever created; it led to the x86 architecture that dominates desktop and server computing today. I’ve been reverse-engineering the 8086 from die photos, and in this post I …
“Corona has changed our lives: it requires us to physicially distance, which in turn leads to social distancing. So what could be a solution? Maybe a pet? But no, Corona comes from animals. Let’s save ourselves from another Corona …
“I’ve been wanting to control my camera switching from my modular synth. So I made a setup where a low to high transition on a digital input on an ESP8266 module generates an OSC message on the WiFi network …
“Giant Board is a single-board computer based on Arm Cortex-A5 SAMA5D27 microprocessor that runs at 500 MHz. It consumes about 140 mAh current when powered from a 3.7 V Lipo battery. Goal of this project : Prepare hardware for the …
“USB was supposed to be universal, and the main goal was to make a hot-swappable, super easy to interface with other devices but over the years the idea went haywire. There are so many different variants of these USB ports …
“This custom keyboard was created to speed up my 3D CAD development. My 60 most used commands are now just a click or two away. The keyboard is fully customizable, uses standard components and is easy to replicate since it …
“This cube is easy to build with no circuit board and minimum external components; and it comes with a lot of animations and effects. This is the third and final project in a series to see how much LED cube …
