In mathematics a signal is a real function of a real variable f(t). In electronics it represents the evolution of a voltage (or a current) over the time and depends on the performances of the stage of the amplifier. Through a memory buffer, samples move to a digital-to-analog converter that produces a voltage signal, after

I recently spoke to Piyush Sevalia, Executive Vice President, Marketing at SiTime Corporation,about their newly introduced 32 kHz TCXO (temperature compensated oscillator) which they claim to be the smallest, lowest power device in the industry. With its tiny footprint and ultra-low power consumption, the SiT1552 MEMS TCXO decreases the size and increases battery life of

When you are waiting for a very important letter to come, it’s really bothersome to go and check the post box again and again. The problem gets worse when you are not at home and anxiously thinking if the letter arrived or not. Well, now IoT or Internet Of Things is your savior. Following this
Smart IoT Postbox with Arduino, ESP-01, and idIoTware Shield Continue Reading
This video shows a simple circuit that can be used to control the position of an typical remote control (RC) style servo with an analog voltage. The PWM (pulse width modulated) control signal format for an RC servo is reviewed, followed by the presentation of a simple circuit that can be used to control the
Circuit Fun: Control an RC Servo with an adjustable DC voltage Continue Reading

Choosing $1 sound card for DC-capable low speed oscilloscope Continue Reading
Here’s something I’ve been working on for a while. It’s a digital guitar effects processor based on a PIC32MX. It started with a conversation with my brother John. We were playing with my mini drum-machine, using the tune mode to mash the hell out of the samples whilst running it though his bass guitar amp
