Battery Sensing and switching for Bedini Systems

[aladinlamp]

I just bulit the entire thing today but nothing happen. A bad sign is the batteries

are getting warm so something definetly wrong with it. i have good background

knowledge on the bedini motor but still something must be wrong with. If you

can give me some advice ,or maybe i can send u some pic if u can point some

thing out on the pic i going to send u would greatly be please. Didn't want to

solder all of my connection so instead i used alligator clips. Just in case i want to

replace my transistor. I don't know if it matter i solder all of the connection are

not. I want so bad to make the motor run, but the trobleshooting is me making so

upset.

My the parts i pick are the source of the problem here is a list of them

- Power Battery (werker wka12 1.3F 12v 1.3Ah Lead Acid)
- Charge Battery ( YUASA 12V NP2.3-12 2.3Ah)
- Potentiometer 1-Megohm Liner-Taper
- Transistor 2N3055
- Resistor 10K-Ohm 1/2 watt 5% tolerance
- Diode 1N4007 1000V & 1N4001 diode
- Alligator clips for connection expect transistor i solder 1N4007 & 1N4001 diode to the Base with Emitter and collector
-Magnets are facing north

The coil doesn't turn to a eletricmagnet i connect the batteries to it, but it's suppose to arract the magnets to the electricmagnet coil

get rid of

- Potentiometer 1-Megohm Liner-Taper
- Resistor 10K-Ohm 1/2 watt 5% tolerance

use just 10K-10turn precision potentiometer, more expensive but perfect for tuning and understanding the role of resistance in this circuit

You might want to switch to the SSG thread is about making a bettery swapper.

Also check out some cool videos that have been made for SSG newbies.

Hi Everybody,

Is anyone currently using this Power analyzer or have an opinion as far as tracking the battery perfomance and other parameters of the SSG .Thx for the input in advance .

Update on battery swapper

Currently the software that came from Dune Buggy is running on the pic. It is now operating the relays, however, for what ever reason the keyboard input via the com port is not working. I can receive from the com port and I see that it is testing the batteries.

I have on order a 12V power supply for this, ( might be some of the problems now I am running at 9V )

But I cannot figure out why the Pic will not receive commands from the com port. I have tested this with a program put onto the pic that allows you to test the com port and that works. So I believe the problem is in some way I am loading this hex file to the pic, or some change in pic or program. Dune buggy had stated to use the program Winpic to program this, but it does not work with my K150 programmer. So I have been using a program called MicroPro that i have loaded the hex file and ran.

I have reverse compiled Dune buggy's program to assembly language, but I have no clue what I am looking at.

Battery Swapper..... WWOOOORRKKSS !!!

HIP HIP HURRAY

I can now swap batteries from my keyboard, or set a threshold voltage for the batteries to swap! At last my 12V power supply came in tonight and after fooling around with it some more, It is working!

Video of the details.

RE: battery swapper.

I have had a request for the instructions to flash the pic. I asked Dude buggy, if I could share it, when I got the code, and he said YES Three cheers for Dude buggy!

However...

I am having trouble uploading this file to this forum I keep getting the message "invalid file". I have tried...

1. Uploading as .hex error.
2. Renaming to .txt error.
3. Zipping the file error.

Any suggestions how I can upload this?

I went through the process of trying to find the problem with attachements Mart. It looks like you can only use the following file extensions 'bmp doc gif jpe jpeg jpg pdf png psd' Should work with .doc .

Pic program .hex file for Dude Buggy's battery swapper

Ok, rename the attached file to .hex and should be good to go.

thanks

got the hex file. thanks. now looking for hardware.
Are you using a capacitive discharge for your charging batteries in your circuits?

I have a dual monopole SSG with 5 - 12volt 4.5ah (1 primary, 4 secondaries), 16 ceramic magnets on aluminum rim, set up draws 210ma from primary for both of the bifilar coils (850 windings of #23 and #26) and achieves an average of 180 rps. I've changed the grease in the wheel bearings to a graphite product called Jig-a-loo.

Here is web page i threw up to illustrate where i'm at on this project. Darcy Klyne's Bedini Monopole Replication
I am at a point where i am unsure of the best way to charge my battery banks. Seems like research is prudent at every stage of the game from now on in. I am a bit of a electronics novice and appreciate any help from anyone. :P

Thanks for getting the pic program for us.

ModVid - Watch and Learn TV is a youtube clone that i host to compile a good collection of rare or important video. Please feel free to share your vids there. In the upload section i have set up a youtube downloader. (makes it easy to move video)

RE: swapper.

No, my charge goes straight to the other batteries not using a capacitor discharge yet. I will need one, but I have a friend that is designing a good dump for capacitors does a slow dump, more effiecient, as I understand will let you know how that goes...

I also am a novice at electronics, I owe a BIG debt to this board and Youtube for the search feature. Has helped me understand many things simply by looking at the how to videos on youtube.

Check out this web page as well...

If you have not been there... Excellent replications there.

I HIGHLY recommend this site for beginners who know little of electronics

Swapper

Marthale: I like your pc based battery swapper (nifty stuff) and might try it later on but what Im looking for is a battery swapper circuit that is part of the swg so the whole thing is self-contained.

I have had 4 others that are now in process of building it. Again, I want to give full credit to Dune Buggy for pioneering this project, I just followed where he paved the way.

You do not have to have the computer hooked up to the swapper, it is good for setting the initial settings of hours it runs, you can say 1 - 48 hours of run time before swaps. I guess it could run off a batter, but I am just running it off of the wall power it pulls 1 watt of power.

But once it is set, you can disconnect the computer and it will run and record the data, then you can pull this data for later.

I ran my 6 Golf cart batteries from 11.71 V to 11V in about 3 weeks time. I am now fully charging them so I can give them another run on the swapper.

I am working on programming my own code so I can record voltages as it goes. Slow going getting the assembler, and figuring out all the registers inside..

holding relay without power

You might want a latching relay. ( with other parts too! )

Just pulse it to change states. No constant current.

like here ... > http://www.goodymt.com/viewproduct_5_e.html

google " latching relay "

Now some designs require constant power ...

I am referring to the old style mechanical or newer magnet type

----------------

That does sound interesting, but as of now I have 8 of the old style relays and will stay with them. I still think you would need like 9 V to initally fire the relay.

I would like to know if there is such a thing as a double pole triple trow relay.

I would like to add another position to the relays that would be to off. I would like to give the batteries a rest after they have done the work of charging to let the battery naturally raise it's own voltage then add it to the mix about 1 hours later.

I have compiled my first assembly language program, and I am trying to figure out how to get the mplab ide software to do what I want it to do with the mpasm software. I am unclear how to get the internals of the chip to do what I want. I have ordered a book of Amazon that should help me get past these hurdles....

Wow working at last

I have just completed my first from scratch assembly program for the battery swapper! I can now switch only two banks instead of the 4 that Dude Buggy's program does.

Boy LOTS to learn in assembly langage testing that it works now, it has swapped two times and seems to be a ok!
