GameIO Review
The guys from www.electrobee.com were so kind to offer me a GameIO card for review. So here it is.
The GameIO, previously called Xiltendo CPLD Starter, is a slot-2 device that adds I/O capabilities to your DS. In a way it is similair to DSerial. It should be fun for a lot of electronics projects.
Super Simple SONAR
Thomas Scarborough’s electronics design have been popular. Here, therefore, is a “super simple” SONAR (designed by him).
New CCO Metal Detector
Thomas Scarborough has designed a new embodiment of the CCO (Coil Coupled Operation) metal detector, a new genre which he invented in 2004. This is the first IC design to appear on the Internet (there is a transistor design on many websites, and IC designs were published by Elektor and EPE). It took me just eight minutes to design this — which illustrates the simplicity of the principle.
Super Simple Counter
The freebie metal detector I previously designed for this blog is by far my most popular post. So here is another circuit I designed today.
