I found the following schematic from online sources. It’s about generating and launching ions. I did not built this circuit. But I’ll present some ideas on how to focus ions so that they will travel a longer distance.

Electrons gather at sharp points in metals. Electrons are emitted from a needle like sharp point as shown in Fig. 2. A negatively-charged plate may be used as an electron reflector to focus electrons along a line, thus producing a tight beam as shown in Fig. 1(b). Even a tighter beam is possible if the needle point is replaced with the structure shown in Fig. 1(c), though experimental verification is needed. To avoid loss due to corona, the entire wire and the reflector, except the sharp emitter, should be covered by an isolating material such as silicon etc. and surface variations should be very smooth.
Configuration shown in Fig. 3 can be used to bunch electrons using a magnetic field. Later, if the magnetic field is cut rapidly, bunched electrons are released and due to the focusing effect of the negatively charged reflector (NCR), they can be launched on to a target. A pulsed magnetic field would do the job if it’s generated by a pulsed capacitor discharge. So, if a HV capacitor is discharged on to a solenoid through an...
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.....
