Some time ago I have presented my new design a mini QuadroCopter. This new design required a controller but tailored to the size of the mini UAV.
It was quite a long time since I have written something about my QuadroCopter. Well the time has come. I have prepared a shot movie to which I invite you to watch.
Read more for some technicalities about the UAV.
Some time ago I have written about my RepRap clogging problem. When I have switched to PLA I had some problems with extruder jams. It was solved by switching to different extruder and adding a fan for active cooling.
Some time ago I have decided to switch from the ABS filament to the PLA filament. This is how it starts 🙂 …
The purpose of this article is to introduce you to one of the methods of making PCB which is the toner transfer method.
A model servo or servomechanism isn’t anything more than just a small DC motor with a transmission and some electronics.
There are situations when we would like to encrypt our Internet traffic. One of those situation is when we use a public computer. Those computers are vulnerable to sniffing. This article will shed some light on this problem.
Below you can see 3D printed components for my quadrocopter:
The Raspberry Pi allows you to connect a camera, either a dedicated one or a Webcam which can be connected via USB port. This post covers how to get an USB Webcam to work.
If your Raspberry Pi is connected to the outside world it is vulnerable. In one of previous post I have described how to make web server out of the Raspberry Pi. There you can find how to make it visible using DDNS.
There are few simple steps which you should follow to secure up your tiny server.
I have done a few project based on AVR microcontrollers. Recently, I have given myself a chance to try out Arduino. After my home thermometer broke down I decided to make a new one. Also it had a few drawback which required fixing. After some time I decided to use Arduino and design a shield for it which would enable this board to measure the temperature and display it. So here it is:
