DIY Your Own Intel 8008 Computer Clock!

Home hobbyists can be divided into two different types. The first type is the follower, which they might only follow what the people taught on the website and do the same, as the inventors did! In other hand, the second type is more like the innovator, where they’ll review, practice and makes some changes or modification with their projects! Honestly, which type of you belongs to? The straight follower or the creative innovator? Well, no matter what type you’re, today’s project is going to blow you off… For your information, the project is a clock based on an Intel 8008 first generation 8 bit microprocessor. Basically, it’s a fully operational 8008 computer. Hence, its 16k of memory space is compatible to be used with several combination or RAM and EPROM. You have to design the project into four input and four output ports. Also, don’t forget to include the front panel, so that it can be used to examine or modify memory, once it jam in an interrupt instruction! Please remember that you can’t load the 8008 computer clock down… Continue reading

The Compact and Powerful AVR-based Power Usage Logger

Nowadays, the electronic and electrical fields have been developed in lighting speed, especially after the invention of Atmel AVR. For those of you that didn’t know this AVR for, it’s a modified Harvard architecture 8-bit RISC single chip microcontroller and it’s the fine product of Atmel that was been developed in 1996. Do you know that the AVR is one of the first microcontroller families, which using on-chip flash memory for program storage, as the opposed to One-Time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time? Today, you’ll going to be exposed yourself to the world of AVR, by DIY an AVR-based power usage logger. For your information, this device monitors household power usage and logs it to an SD card. A simple analog front-end amplifies the signals from voltage and current detectors. Beside that, an ATmega168 microcontroller will be used to compute the power consumption by simply using the formula P=V*I, where V is for voltage and I is for current! For the consistency, the voltage and current will be sampled at 9615 Hz so… Continue reading

The Simplest AVR Controlled Clock

You’re always having the determination, which you would like to build yourself a simple and easy to navigate Atmel AVR controlled clock? However, your dream seems doesn’t become a reality, due to the many factors? Well, it wasn’t too late as long as you have the urge here… Oh, for those of you that don’t know about the definition of “AVR”, it is a Harvard architecture 8-bit RISC, which have been fully modified and developed by Atmel in 1996. The AVR has been known as the first ever microcontroller that being used in the on-chip flash memory for the program storage purposes. The types of programs can be One-Time Programmable ROM, EPROM, or EEPROM. There are four basic families for the AVRs and there are: tinyAVRs, which equipped with 1-8 kB program memory and 8-32-pin package megaAVRs, where it’s a 4-256 kB program memory and 28-100-pin package XMEGA is a 16-256 kB program memory and 44-100-pin package Application specific AVRs, which are a megaAVRs with some special features that not found on the other members of the AVR family, example… Continue reading
