Arduino Zero

double -> decimal digits

It is well-known that the x86 instruction set is baroque, overcomplicated, and redundantly redundant. We show just how much fluff
it has by demonstrating that it remains Turing-complete when reduced to just one instruction.

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 flag earlier 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 enough that it can be explained at the silicon level.

Radfahrer mit Bastelgeschick können sich mit einem Bausatz von Adafruit einen Helm bauen, der ihnen blinkend den Weg weist. Die auf der Arduino-Plattform basierende Hardware prüft Richtung und Position des Radfahrers und blinkt dann entweder links, rechts oder geradeaus in seinem Sichtfeld.
