An older article before the time of the plague. Could be a bit outdated. Original creation 26/01/2020 In this short report I will try to explain the procedure of creating a simple C# project with Visual Studio 2019 that will run on a Raspberry Pi 3B+. This project will utilize a I2C sensor (tmp75) to… Read More Creating and Running Simple C# applications on Raspberry Pi 3 with mono
One of the core elements of this project is the analogue amplifier that is the intermediate stage between the sensor and the Arduino board. Its purpose is to amplify the incoming signal from the sensor to measurable levels and sustain the voltage (that indicates the particle energy) long enough for the Arduino to sample it… Read More Radon Detector Pre-Amplifier
After messing around with BRAM modules in Vivado and experimenting with ways to initialize them, I have concluded that the best way to do so is the .coe file. A simple way to create one is python is shown below. References used : https://www.xilinx.com/support/documentation/sw_manuals/xilinx11/cgn_r_coe_file_syntax.htm PS: I know that truncating the last character of the file… Read More COE file creation in Python
Not really related to electronics or even programming but I have been toying with HxD and the effect that a Hex Editor can have on a picture as we “corrupt” the data within for quite a while. The results varied from interesting to outright destroying the picture. The real incentive to create something worthwhile came… Read More Creating glitch art by using HxD
Introduction The goal of this project is to create a simple model of a super heterodyne receiver on Matlab and test the efficiency of it as we try to demodulate sample radio files that are given to us. By the end of this post you will understand each stage of this receiver, how it works… Read More Simulation of a Superheterodyne receiver in Matlab
So, i was trying to make my laptop work as a hot spot.Pretty standard stuff by reading all those tutorials on the internet. I thought “i can do better than that”, so i made a simple batch file to execute the commands needed (for example to set your network parameters or close/open the network). The… Read More The importance of “EnableDelayExpansion” in batch
By using basic graph theory, we will try to find the complementary networks in a CMOS circuit. Our goal here is not to analyze graph theory or Euler paths but to understand and quickly determine said networks. This will be quicker and more effective by solving an example. Let us have the following Nmos network:… Read More Finding the complementary network in a CMOS circuit
By analyzing my blog data concerning an older post of mine , i realized that the majority of hits i got were about the schematic and the board layout of the FT232RL testing circuit.Without further ado, you can find the whole project in GitHub as always. The schematic of the circuit in eagle. A couple… Read More FT232RL Breakout Board
Click HERE to download the project from GitHub.Also bear in mind that this is still a work in progress and there are plans to update this library. Have you ever tried to make your arduino speak Morse to you?Ugh,no,not really? Well,for all those interested, grab your arduinos and 8 ohm speakers and let’s go! This… Read More A simple library for Morse code in Arduino
September 7,2015: This article is pretty much obsolete. To my surprise , though, HP’s drivers have been updated, so there should not be any problems. This is gonna be a short one. It is about a problem that came up when i tried to install the HP drivers of my “ancient” HP 5740 inkjet on… Read More HP Deskjet 5740 and the notorious hpf4ec10.dat
