(A small part of) The 6502 chip explained down to the silicon

The 6502 CPU's overflow flag explained at the silicon level  In this article, I show how overflow is computed in the 6502 microprocessor at the transistor and silicon level. I've discussed the mathematics of the 6502 overflow flagearlier and thought it would be interesting to look at the actual chip-level implementation. Even though the overflow flag is a slightly obscure feature, its circuit is simple enou ...

Make a Variable Resistor with 1 Million Settings

Make a Variable Resistor with 1 Million Settings Last week in my college physics lab we got to use these variable resistance 'boxes'. They had two inputs and six dials, and could generate one million different resistances across the two inputs. I knew I had to have one, and why not make it myself? This tutorial demonstrates how to build one for yourself for pretty cheap. Materials: 3" x 5" x 2" plastic proj ...

FidoCadJ – Simple and intuitive 2D vector drawing for electronics and not only

Description A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation here, sorry!) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few cl ...
