Being able to capture sound, store it and play it over and over again never fails to leave me in awe of its pioneers, from Thomas Edison to Alan Blumlein, the British electrical engineer who, in 1931, invented ‘binaural recording’ – what we now call ‘stereo’. (Never heard of him? Blumlein amassed 128 patents in

I own two excellent AM transmitters – one is homemade with a single 6888 Tube and the other is a restored old KnightKit Broadcaster. Additionally, I have a high-quality solid state transmitter from SSTRAN that I use to broadcast music to my collection of repaired or refurbished antique AM radios. I desired a top-notch FM

This article will discuss the process of utilizing an Arduino Uno to effectively manage a boost converter with a power output of at least 10 watts. By utilizing only a few components such as an inductor, capacitor, diode, and a FET, it is possible to create a discrete boost converter. Please refer to the Wikipedia

Introduction Electrodes on the skin are used to detect muscle (EMG), brain (EEG), and heart (ECG/EKG) functions. These electrophysiological measures are commonly utilized for clinical use, research investigations, and even by enthusiasts such as those intrigued by brain computer interfaces. Numerous commercial systems are categorized as “medical grade”, indicating that they come at a high

Create an inexpensive basic wireless mesh network with arduinos and long range APC220 radio modules. Wireless mesh networks have the ability to accommodate non-functioning individual nodes and are resilient in challenging environments like forests and hills, where direct data transmission between points may be limited. Step 1: How the mesh works This is a wireless

Why make your own Arduino control system? Once I finished building my homemade telescope mount, I installed a Meade DS motor kit to power it. This system was very sluggish, lacking in power, and untrustworthy. I couldn’t modify the programming or upkeep the system either. I chose to develop my own telescope control system from

In this article, we demonstrate how to create a compact and practical Arduino DMX512 controller that can be used to operate a smoke machine with DMX or for testing purposes. Arduino Mega, Arduino UNO, and other similar devices can be utilized with minor modifications. Only a few cheap components are utilized. The setup includes 6

The Arduino is perhaps the coolest thing on earth. There are many types, the Uno, the Mega, the Pro, the Pro Mini, etc. etc. But one thing that often can be a problem is that you only have a limited number of inputs and outputs. There are many solutions for that, ranging from multiplexers to
Extra inputs for Arduino with a keyboard Continue Reading
For our project, we built a planar, 2 degree-of-freedom haptic device for educational use. The design is based on a 5-bar mechanism. We wanted to build a device that would have the versatility to teach various concepts, but would still be relatively affordable (as the goal is implementation in classrooms). For this reason, we designed
