Electronic Fuse Controlled by a Basic Stamp This Project is almost done

sam_sam_sam

Hi· Every One

I took a·Transformer···from a Low Voltage 12 volt AC Light

Removed the winding for the 12 volt part
I put· 3 pairs of wire Two Turn Each Back on the Transformer

This will work for 5 amp @ 120 volt AC as you can see in the photo below

Then I used a ADC 0831 and a 4N33 Optic Sensor to work with the Basic Stamp

I also have a 2 line Parallax 2 LCD Display that I am using

The Photo is not there yet

Here is what I have so far

The reason for this Project is because it has a 2 Amp fuse for the Speed Controller for the·Milling Machine Controller·that·I keep blowing so

I though this some thing that a Basic Stamp could do

I have not·written the part for the trip the relay· yet but i have circuity for it working· this will be easy to do

·I have the LCD displaying the amps··

What I want LCD Display is·if I can get it to work the way i want it to work For each charter·I want to use a (*) to show 100 millamps this just an example

I would like to have this on line two instead what I have now

Wouldn't it be better to find out why the fuse is blowing in the first place?

Thank You For your Reply

I know the reason why the fuse keep blowing is if you try to cut to fast then you will blow the fuse·I want some thing that dose two thing

One I want to see a display when i am going to fast

Two When i have gone way to fast the Basic Stamp Take over and shut down the Milling Machine

By The Basic Stamp taking Over the control before the fuse blows

I just do not have the shut down writen yet maybe i will write it today

Hi every one

This has been the hardest project that done so far

The biggest problem has been getting the display work right

When I would add the INPUTS 3 and 4 The LCD would not want to work or·just not·come on at all or just freeze

after many hours of working on this project I think I have it working the way i want it

One thing·I found my self doing a lot was using··· laps = laps + 1 and DEBUG DEC5 ? LAPS to see where it was hang· at· BUT very use full routine

·

It has same file name but is very different

Hi Again Every One

I found one more problem I had the display working OK· when testing it but as soon as·I put the routine in to control the Power Relay then the Display

was acting up and·So·I went back to using the ADC Demo in Stamp Works again then This Demo would not work right either

It turn out that the resister that i was using with a 2N2222A was to low of a value

I was using a 220 ohm so·I changed it to a 560 ohm resister and now it works a lot better

I am not sure·which one was happing

The Basic Stamp was to draw to much current on that pin·or the Basic Stamp was Resetting it self because of it


The Routine has been changed again because I found that some of what i had before would not work right
