Pulse Generator, part suggestions?

Hey, I want to make an external pulse generator, mainly so I can power a simple coilgun. I know I have to have a bunch of capacitors hooked up in parallel, but what value would be ideal? And what kind of transformer do I need? Say I use a 9v battery, how would I calculate the ouptut voltage? I know trial and error would work best for me, but I don't have any transformers lying around so I need advice on which one to get. Thanks.

solar pulse motor help! Answered

Ok so I have two questions. First I have a very week solar panel like it can't even power a motor I can power with a AA. I would like to know how to test how much voltage it can produce. Second I'm wondering if I could use this week solar panel to charge some little capacitors which would charge up and then discharge with enough voltage to power my motor. Would this work? thanks for your help!

Rapid Pulse LED Program

Hi there! I have successfully been making some LED hula-hoops but my ultimate challenge lies before me: I want to program colour-changing LEDs so that they pulse ultra-fast and appear 'white' when at standstill but leave rainbow trails when they move. I believe it to be an optical illusion caused by the pulsing... I assume this requires a PIC program but I have no idea where to start or even if I am on the right track - does anyone out there know how I might achieve this? thanking you in advance, Amelia

Turn dial to generate pulses

Here is my proposal. I'm building a pan/tilt unit. I plan to have a 200 step motor attached to a 20:1 worm gear, (the latter is needed so it will 'lock' in place, and not be solely reliant on the motor's holding torque.. So in order for the output shaft to turn 180 degrees needs the worm gear to turn 10 times. In turn the motor must do 10 revs, which would need 2000 pulse steps. It's the pulse generation that's proving difficult. Whilst a 555 timer could generate pulses, I want it to be 'mechanical' For example, if I turn the knob 90 degrees, I want to create 1000 pulses, (45 degrees creates 500 pulses) and so on, so the knob matches the physical position of the camera. If I turn the knob 180 degrees in 1 second ... the motor will turn 180 degrees in 1 sec. If I turn the knob slowly, pulses will be generated slowly, and the camera/motor will turn slowly. My idea at present is some sort of optical encoder ... but that would need 4000 divisions on the wheel!! Or - a 1024ppr wheel with a 1:4 step up gearing ... but such encoders are several hunderd Pounds!! And I would need two of them!! I have software that will allow me to print an encoder wheel, but resolution will have to be 'course' since it will use an LED / transistor, so I suspect around 64 divs. I purchased a RC servo, wondering if I could remove the motor, and turn the output shaft by hand. Couldn't be done. I've also considered 'planatary gears' in reverse to 'step up' the revs ... but I cannot locate any 'hobbyist' versions other than the Tamayia type. Also briefly looked at RC servos, but having done the maths, it would be impractical to get the output to move (say) 0.1 degrees as the motor would only move about 1/4 of a rev and have no torque!! (One option may be to make it continuos rev, and place a feedback pot externally.but again, moving 0.1 degree around a pot would create minimal feedback) Incidentally, 0.1 degrees is the stepper resolution 180 degrees / 2000 steps Anyone any ideas? Bearing in mind that the speed of the pulse train is dependant on how fast the control (pot) is turned, and also matches physical camera position. Encoders are preferred option as it's then possible to electronically guage which way the motor is turning. If electronic, here is (sort of) what the circuit would need to compute. (Sample and hold?) Moved from 0 to 45 degrees in one second. That degree of movement needs 500 pulses, thus need to generate a pulse width to get 500 pulses in 1 second timescale. ** This is just to give an example. The actual sampling rate would be much faster. If it was a 'slow' 1/10th second, in the above example it would check every 4.5 degrees, and generate 50 pulses in that time scale.

Need help with pulse width modulation for motor for aiming laser pointer

I'm trying to build a model with a small remote control laser pointer aiming system. I'm not exactly a mechanical genius and, I don't want to spend over $100, or much over $30 if I can help it. I figured I could set up a simple pulley system with some cord running from the laser pointer to two small electric motors, one for right and left and another for up and down. I don't need the laser pointer to swivel 360 degrees, just about 90 vertically and horizontally would work fine. If I were to attach a few monetary switches, I would be able to run the motors one way or the other, and get the laser pointer to point wherever I want. The main problem I am having is that every electric motor I find has a RPM in the thousands. Such speed would jolt the laser to one side or the other without any means of fine adjustments in aiming. I've looked around and it seems to be the general idea that either a PWM (pulse width modulation) controller or gear box are the best options to get lower RPM out of a motor. I don't have much room to work with where I want to mount the laser pointer, so I decided to go with a PWM controller and spread the components around the model to save space. I've been doing my best to construct this.... www.discovercircuits.com/PDF-FILES/SIMPLEPWM2.pdf ... but my knowledge of circuitry is rather limited, having only take a college course on basic circuitry, I'm in a little over my head. Could someone please identify the component labeled "PULSE WIDTH ADJ" (center bottom, between the two diodes) is it two 250K resistors in series with the lead to the left acting as a resistive load or something else? Also, what is the component labeled "IRFD024" (far right below the motor) I would be very appreciative for any information that would aid me in getting a PWM controller to slow a motor down to around 50 RPM. If some one has a better idea all together, I would be willing to scrap the motors for another project and start from scratch.

What is the best design for an electromagnet in a pulse engine?

I am a complete bigger to all magnets, electromagnets, and electronics in general. Recently I've had an interested in different electric motors and have been looking into trying to make a pulse motor that is both efficient and powerful. To do this I want to be able to have the best arrangement of the magnetic fields of the neodymium magnets on the spinning disk and the electromagnets on the outside. I started playing around with the magnetic calculator found on https://www.kjmagnetics.com/calculator.asp but I don't really know what I'm looking at, just that different shapes and sizes have different fields and strengths.  Since a pulse motor is built by using an electromagnet to repel a neodymium magnet, what would be the best design for a strong burst electromagnet in the direction it's repelling the neodymium magnet? Also, what would be the best shape for the magnet to have the biggest repelling effect from the pulsing electromagnets?

Hall effect sensor to trigger relay

Hi!

My control system can't deal with this. What I need is a simple circuit to turn the sensor's pulse output into a contact closure. Can anyone help? Thank you!

Controlling two servos with one pin and a NOT-gate

Here's an interesting idea. It may be possible to control two servos independently with only one output pin and an inverter/NOT-gate. Normally, a servo is at its 'center' position when a pulse is 1.5 ms & its angle (or speed for continuous servos) is based on the difference between the length of time of the pulse it received & the base-time of 1.5ms. The servo itself does not react to the time BETWEEN pulses however. If the signal was inverted, the result would be a pulse with a time being that of the time between pulses of the initial signal. If the width of a pulse and the time between pulses can be independently controlled, then it would be possible to control one servo with the signal directly, and another servo using the inverted signal. I found something similar here [http://www.diyrc.com/reversers.htm] but it seems to be intended for 'reversing' the signal used to control one of the servos.

Triggering a flash circuit with a voltage pulse across a transistor

Hi All,        question from a newbie. I'm working on a project for my (steampunk) daughter. For part of it I've taken the flash circuit from a disposable camera (PDF 1:Flash+MechanicalTrigger). This works just fine when I close the trigger mechanically. What I want to do is trigger it with the same pulse (from a 555 timer) that I'll be using to do other things at the same time. To this end I added a transistor as shown in PDF 2:Flash with transistorTrigger. My intention is to feed the 555 pulse to base, saturating it and triggering the flash. Result, abject failure. Help! The proposed triggering transistor is an MJE340(NPN). When set up as shown the indicator LED glows but voltage across Emitter-Base produces no result. When testing I noticed that if I mechanically make the collector-transformer connection it triggers a flash, even with no voltage across emitter-base. I'm stumped. Any ideas very gratefully accepted. Thanks, Fred.
