Build your very own burning laser. Unlike other popular ways of building your own burning laser I will show you how to do it properly to ensure a long and healthy life for your new laser. There are several reasons for building a burning laser this way instead of just connecting it to batteries and having it die in a couple days or months. The best reason is that it will be just a bit more powerful. But the main reason

for building this circuit is to regulate voltage and current. As simple as connecting your diode to a set of AA batteries is. You must realize that that you are feeding the diode too much current. It is also not protected from other dangers such as voltage spikes. This driver circuit will take care of that. One of the most important things you will need to do this project is a laser diode. The second is an Aixiz housing to put your diode in. You need the Aixiz housing in order to focus you beam when you are finished. There is a link to purchase one right from Aixiz below in the parts list. You can also buy the laser diode on ebay or you can simply harvest your own from an old or broken DVD Burner you may have laying around. And to answer the question you are asking yourself right now, yes it must be a DVD Burner. Any that are 16x or higher in speed. Normal DVD player diodes will not create a laser pointer with burning power. Never use a CD Burner for this project either. They contain infrared diodes. The light they emit is invisible to the naked eye and contain enough power to blind you before you will even realize it is happening. Simply put, stay away from CD Burner diodes. You cant actually see the laser it will make anyway. Now, harvesting a laser diode can be a tricky process as they tend to be very fragile and sensitive to static and other forms of shock. It is very important to take your time in harvesting your...
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.....
