First thing`s first, what software to use I went with CadSoft Eagle primarily because there are lots of tutorials out there covering it, and that seemed like a good place to start. Once I understand the process I can worry about what software I use, but for now, there`s a free-to-use version of Eagle, it`ll do. On my Kubuntu box, installing Eagle

was just a case of installing the eagle package. For the Mac I had to download the installer from CadSoft`s website. I also downloaded and installedthe Sparkfun Eagle Library and the Adafruit Eagle Library. They really helped to simplify things, though I did find that I had to modify one or two of the packages, mainly just prettifying the silkscreen. I just couldn`t help myself! I`m going to skip theintricaciesof using Eagle, these posts are really just a log of what I`ve been up to and my own commentary on the process. There are plenty of tutorials out there on how to use Eagle. A good place to start would be the Sparkfun Beginning Embedded Electronics Tutorials. Eagle`s UI is unlike any I`ve come across. I`m still not quite sure if it`s genius or justreallyold. I suspect it`s the latter and that the paradigm used to interact with a computer has somewhat shifted since it`s day. However, if it ain`t broke, don`t fix it, and if you`re clever enough to be designing electronics, then you`re clever enough to work it! All I will say is that there are times when it seems staggeringlycounter-intuitive, particularlythe library editor. Also, I found the naming conventions used in some of the component libraries to be perverse. Yeah-yeah, I know, don`t blame the libraries, blame the person who doesn`t know what he`s looking at! All I`m saying is, the component descriptions could be a little more descriptive! Once Eagle was...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
