How the Bug-Eyed Eggliner came to life along with instructions that will help you to make your own. I believe that you can also use many of the concepts presented here in other projects and animations. The honey bee Eggliner already has two large eyes painted atop its body. It seemed logical to make them larger, 3 dimensional, illuminated and movable. I experimented with

a number of different spheres until I found wooden balls at Michaels, a local craft store. Wood is easy to paint and to work with simple tools and the balls came in a variety of different sizes. I decided to add a single 5mm LED to the center of each eyeball and to design and build a servo based mechanism to move the eyeballs back and forth. A PICAXE microcontroller is used to drive the servo and to blink the lights on and off. This list shows what I used to make the Bug-Eyed Eggliner. There are many substitutions that could be made if you can`t locate exactly what is shown here. Brass tubing - 12" long, 7/32" diameter - search eBay for "brass tube 7/32" - locally available at hardware stores & hobby shops - this must fit smoothly inside of the 1/4" tube described above Remove the motor block and base from the Eggliner by removing the outer four screws from the bottom (circled below). The inner screws hold the motor block to the base and do not need to be removed. Unsolder the bundle of red and black wires from the circuit board (area circled below). These wires connect the Eggliner`s interior lights to track power. We will solder them back on when we are all done. Remove the white cardboard oval that is inside of the Eggliner`s body. You can pry off the blobs of hot melt glue that hold it in place or you can cut it out. It will not be reused so damaging it during removal is not an issue. Unless you have VERY tiny hands it...
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.....
