Cpu_from_scratch [bradthx.net projects] Recently I decided to take on a very ambitious project to design my own microprocessor from scratch.

A couple of things inspired me on this project, the first being a book I finished, Digital Apollo by David A. Mindell. This book details the design and engineering behind the AGC (Apollo guidance computer) and I was amazed to learn how well designed both the hardware and software were for it's time. The fact that it was designed completely with 3-input nor gates made it even more amazing. The second reason is the fact that several other people have done the exact same thing, built entire computers from basic TTL logic. The idea of designing a cpu from complete scratch using all TTL logic is just exciting. The specifications of my cpu will be as follows: Von Neumann architecture. The supporting hardware to the cpu will be: 16K of ram Real-time clock Memory-mapped i/o for output display, and input.

I've had a lot of requests lately for more information about macro photography, so as a little Valentine's gift to you - I've written a step-by-step guide for capturing those close-ups.

Have you seen a beautiful photograph in a book or magazine that captures all the detail of a flower or insect, close-up? The art of taking pictures of things extremely close-up is called macro photography. Professional photographers have expensive cameras and lenses that enable them to capture these macro shots in great detail, but did you know that your compact digital camera is also capable of macro shots?

You’ve probably already noticed it, but let me formally introduce you to the flower icon on the back of your camera – it looks like this: Pressing this flower icon button and activating the macro mode will enable you to focus closer to your subject and capture details in your images that were previously too small or out of focus. The list is endless! Potential problems and solutions Tips and tricks. Witness Camera. Video surveillance systems have rapidly grown from being a specialized equipment for high-risk areas (like banks and airports), to the point of being standard facilities of most places open to the public.

Nowadays, no shopping centre, office, industry can afford lacking one. In conjunction with a time-lapse video recorder, these little cameras play an active role discouraging theft and collecting evidences and precious information about the offenders. Despite their huge commercial success, video surveillance recorders have had little impact on residential markets. No doubt they would be useful at home as well as they are at work: according to the Police, most home thieves go unpunished, so in a sense homeowners must help for themselves. MAKE: Blog: HOW TO - Make Printed circuit boards - An illustrate. Here’s a good tutorial on making your own PCBs (Printed circuit boards).

And below is our round up with the many other methods - Creating Printed Circuit Boards (PCBs) is easy and fun for the whole family! But read the disclaimer — heat and corrosive chemicals are dangerous ;-) After you’ve prototyped and tested your circuit design, creating a PCB will provide a sturdy and reliable backbone for your circuit and will give your project a professional finished quality. Using PCBs can even help reduce the time you spend building circuits, especially if you are producing multiple units, as you only need to follow a parts placement diagram (there’s no longer any need to worry about specific interconnections).As is usually the case, there is more than one way to do it: there are numerous ways to create PCBs.
