This chapter provides detailed schematics of a variety of power supplies suitable for use with the common Ar/Kr ion tubes available to the hobbyist on the surplus market. Included are examples of commercial designs (Omnichrome 150R and 532 head, Lexel 88 and head) as well a somewhat simpler but fully capable system for small air-cooled ion tubes (

SG-IL1) that may be constructed from readily available parts and will be satisfactory for typical experimental and light show applications, and may be easily modified to handle larger ion tubes or provide additional features. There are also a couple of `bare bones` designs (SG-IT1 and SG-IX1/SG-IY1) that can be `thrown together` relatively quickly and inexpensively and are useful for basic testing of Ar/Kr ion laser tubes. Either of these can be converted into a full featured unit at a later time. There are also schematics of several other ion laser heads including those from NEC and Cyonics/Uniphase, as well as interconnect wiring for some common systems. In conjunction with the other chapters on Ar/Kr ion lasers, these sets of schematics can be useful for understanding the principles of operation of ion laser power supplies or for repair of a broken unit. While what are presented here aren`t really complete plans, with a bit of effort, they can be adapted to a variety of ion laser tubes to provide any degree of performance and sophistication desired - from basic and simple to full featured with all sorts of bells and whistles. Brief descriptions are also provided of the Lexel-95 PSU, Spectra-Physics 265 exciter with a 165-3 argon head, and a few other systems. Schematics for these may be added in the future. The chart below lists each of the power supplies described in this chapter (most with schematics) and the...
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.....
