A 3-dimensional LED cube, which I can program, to create Art. No more `Doug Stick Figures`, but something really cool. Follow along as I create Art. I looked through my parts bins to see if I had any microcontrollers left over as I was planning on doing the design around what I had. I found a PIC16F688 and was a little disappointed as it is not the best microcontroller on the planet, but the challenge is alway good.

So the core of this project will be this microcontroller. Its a start right As I have not done much with LED`s, other than to use them in circuits as a means of communicating whether the power was on or off, or what state the computer program was in, it was time to turn to google. After a short google search, I decided that the best starting point would be the datasheet on the PIC. While I was reading that I would have to continually eat tacks to stay awake and surf the net to earn the courage to come back to RTFM. A design was starting to form in my mind and I thought of a real simple circuit. I read some more datasheets, specifically on the STP16CP05 and finished the PIC datasheet and WHAM! Simple solution. Not really. I read for days and found this guy on web who really explained the core mechanics. Once the circuit was drawn I went into Eagle Cad Software to complete the circuit board. Everything tested out and the design was sent out to the PCB shop. While waiting for that I decided to tackle the tedious work of soldering together the actual LED cube. This part is very important as you need to ensure that the cube is really square. Not only that, there are a total of 125 LEDs in this project, so its a good idea to test everything as you go. To make sure that the cube would be square I made a jig out of 3/4 inch MDF board. I drilled 5mm holes for the LED`s and here is the final jig. I built the cube row by row. Once a...
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.....
