Introduction For our final project we made a digital vocoder, which could be accomplished over this semester’s remote desktop environment. A vocoder is a synthesizer that generates sounds which are modulated by an input signal. It was originally designed to reduce the bandwidth of voice signals over the telephone, but was never introduced practically. It […]

Texas Instruments released the TPS62912 and TPS62913 family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. They offer low noise of 20 µVRMS for frequencies ranging from 100 Hz to 100 kHz and ultra-low output-voltage ripple of 10 µVRMS. Traditional low-noise power supply architectures include such technology like DC/DC converters, low-noise LDO, and an off-chip filter, like a ferrite bead. Integrating ferrite-bead

Introduction Dual Element Transducers are a kind of long-wave transducer with a split element. Half of the element is a transmitter, while the other half is a receiver. With dual element transducers, you can have an audio and visual performance simultaneously. There are many advantages to using dual element transducers in your projects, which you

Overview Our project consists of a 2m DotStar LED strip with 120 individually addressable LEDs and seven accelerometers with the Big Board to depict three different rides that are typically found in an amusement park: the roller coaster, the drop tower, and the bouncer. We implement 1D kinematic equations iteratively to approximate the real-world physics

Introduction and High-Level Design When we were brainstorming ideas, each one of us had different interests. Max wanted to do an audio-related project as he is working for McIntosh, a company that designs and manufactures handcrafted legendary home audio systems. Ben wanted to make something that would be highly visually appealing. Alek wanted to take
The DSG3000B RF Signal Generator series simplifies high power setup since an external amplifier is not needed. Engineers can generate more complex signals without additional hardware using the modulation schemes supplied in the DSG3000B with both internal and external IQ modulation capabilities. Saelig Company, Inc. has introduced the Rigol DSG3000B RF Signal Generator series, improving on the previous DSG3000

While adulations were still being showered on his work on the MORPHESP 240, Dr. Philippe Cadic (@Sulfroid on twitter), recently shared progress on another project called the RFL-Watch, via his twitter handle which is usually loaded with reports on the progress of his projects. Based on the RAK4260, the RFL-Watch is a wearable LoRa communicator device which at the

How about a method of automatic identification through radio signals that can bring you security and control the access of people to a certain location? This is possible through radio frequency identification or RFID from the English Radio Frequency Identification. And it is the assembly of this system that I am going to teach you

This little project is an example of a simple audio application using a PIC micro-controller. We decided to use the PIC18F4550 micro-controller for memory purposes. Using only digital inputs and outputs, we developed this simple piano/synthesizer with an 8 bit kind of style: Inputs from b1 to b11 are the push buttons in the circuit while
It’s a Microcontroller Based DIY Electronics Project. Named Wireless RF Module Using PIC Microcontroller. The RF module is a small electronic circuit used to transmit, receive, or transceive radio waves on one of a number of carrier frequencies. RF modules are widely used in consumer applications such as garage door openers, wireless alarm systems, industrial
