Motivation I was building some Lo-Fi CMOS synthies, just like the ones you see here: http://hackaday.com/2015/02/04/logic-noise-sweet-sweet-oscillator-sounds/ or here: http://www.nicolascollins.com/hackingtutorial11.htm Soon after I played around with some simple sequencers and multiplexers to generate more complex sound patterns. I thought it would be cool to have a device to gate oscillators or switch multiplexers with a random

Hey everyone, back with another project. The antiAFK is something I originally started working on almost a year ago, but its only been since 2014 started that I’ve been making real progress on all my projects. Plus, I just finished my MSc the other day so now I’ve got all the time to work on
antiAFK – Sending random keyboard commands Continue Reading
Transistors operating in their avalanche regions are often used to generate fast rise pulses (seeavalanche pulse generator using 2N3904). Many transistors can also avalanche when the connections to collector and emitter are reversed. When operating in reverse avalanche region, these transistors are sometimes referred to as negistors. Because the asymmetry and doping differences between the base-emitter

A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. With
New electronic technique promises to double optical fiber communications reach Continue Reading
Last night was another BuildBrighton nerd-meet-up and, luckily, we had a couple of these new fangled ESP8266 wifi modules to try out. In case you’ve been living in a cave with a tin can tied to the end of piece of string as an internet connection, you’ll probably know that these are the ultra-cheap wifi

A new kind of battery invented by Jay Whitacre, a professor of materials science at Carnegie Mellon University and founder of the startup Aquion Energy, could make renewable electricity more practical and economical around the world. Aquion is about to start full-scale production of the batteries at a new factory in Mount Pleasant, Pennsylvania. Whitacre

Get straight to the action. Connect sensors to your Arduino in literally 2 seconds. $35,000 Stretch Goal: On-board sensor tester If we hit this goal, we will include on-board LEDs that can be controlled from your Arduino board using your PWM/IO pins. This will let you quickly see how each sensor responds (ie. more you

Hi all! With a bit of delay, here’s my last work, a PICnano breadboard based on the PIC18F2550 microcontroller. I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino
