For now, updates are only being made to the github repository. https://github.com/edson-acordi/4bit-microcomputer Main Features: Implements a 4 bit CPU2k x 16 Program Memory (up to 4k)2k x 4 RAM (up to 4k)4 Output Ports (16 outputs)4 Input Ports (16...
Orao's keyboard input works by shorting connections between 6 data lines (D4-D7) and 10 address lines (A0-A9). When a key is pressed, the connection is shorted between corresponding lines to input a key press. I.e., to type "A", the key short address...
Overview: Hardware tests have determined that measuring the average (after applying standard deviation) time-of-flight of approximately 500+ round-trip transmissions can produce reasonably consistent results. While this has not produced results that...
TD4 CPU Here is a schematic from the Internet: (source: http://kamakurium.com/wp-content/uploads/2016/01/cpu_td4.jpg) The entire CPU has only 12 TTL chips. Yes it has a switch based ROM! The schematic also shows the 12 OpCodes. It is not perfect,...
KEY FEATURES: Rotary Volume ControlTouch Based Mute/Unmute ControlAutomatic Potentiometer Position Determination and Calculation (this means that anytime the device is unplugged and plugged back into a computer the code calculates the position of the...
If you need to add some rotary encoder to your project, the I2C Encoder is the right choice! Reading a rotary encoder is not easy task, you need at least 2 interrupt pins for each encoder. When you need to add more than one encoder, it becomes more complicated...
Arduino Motor Shield PCB V1 | 4 Motors at Once Hey guys, welcome back. In my previous post, I explained what an H Bridge Circuit is, L293D motor driver IC and piggybacking L293D Motor driver IC for driving high current motor drivers. In this...
How does it work ? A basic acoustic levitator has two main parts: a transducer, which is a vibrating surface that emits sound, and a reflector. Often, the transducer and reflector have concave surfaces to help focus the sound. A sound wave moves away...
Some key parameters of the proposed extension design:Internal registers extended from 12 to 16 bitsProgramming model extended to contain:4 accumulators (each with own L(ink) flip-flop)8 index registers1 of 4 accumulators and its Link are the present...
Here's a youtube video of the driver running the 4 Digit Demo program:In order to control many LCD/LED segments using an Arduino (a typical 4 digit display has 32 segments) a display driver is required. These are integrated circuits which receive a serial...
A few months ago I decided to see if my first computer still worked. It's been languishing in various boxes and closets for nearly forty years now. This is what the computer, an Explorer 85 from Netronics Research, looks like: The three...
Circuit Design of Digital Thermometer The temperature sensor used in this project is LM35. The output of a temperature sensor is directly proportional to the temperature but in analogue form. Hence, the output of LM35 that means pin 2 is connected to...
1. PERSEUS-68 When I was 16 years old and personal computers did not yet exist in the world, I was determined to complete a computer on my own by 1980, when I would have turned 20. The computer I built in 1980 to achieve this goal was...
