Instant Start 18 fet Infineon Boards are here...

Thats got to be the most enviromently friendly burnout Hu?
 
check my sig for my burnout on youtube... i thought that was pertty good lol

-steveo
 
Yup I love being me! And a am very happy I found a guy like methods to show me the way :wink:

Got a bit of a video up, check sig! :lol:

Outstanding video Arlo! LOL! Top notch stuff! :) Burnouts till the tires blow always will have a special place in my heart. :)
Thanks man/guys. I have alot more footage but the helmet cam I put on my helmet would not focus where I wanted so most of the video from it is useless.
I will buy one my self soon!
 
The part in the vid where you go to burn out, but the tire hooks solid, and you've got a bizzilion amps on tap at the battery, and the controller just takes it and no magic smoke escapes. That is a damn strong controller. You're doing your best to try to make something break, but you went with invincible LiPo, a Methy controller, and an X5. Damn good choices in parts to make something able to handle loads of abuse. :) Great build, and great video Arlo!

Its funny you say that Luke because after I had it spining for a while I remember pulling back on the handdle bars slightly for more smoke! I never was trying to push forward to lighten the rear wheel I was trying to hold the front wheel down to prevent it from launching out from under me and causing damage to my balls or my friends truck in front of me. :twisted: And yup I would not bag my x5 like this if I hadn't of built a cooling system for it!

Credit where credit is due - he built up that controller himself :)
All I did was sell him the parts at an incredible loss :roll:

Why did you do that? Man I sure am happy you did though. :mrgreen:
As for credit lets just pass that to luck! I don't think you will want to see how hacked the inside of my bord is now. Next one wiil be nicer I promiss. Just need to quit blowing fets. And as long as I don't take it apart again it may be ok. Last time I took it apart I needed to test settings so I powered it up without a cover on it and BAM lightling flashed through the house. My GF was on the phone with her dad and she said she is pretty sure there isn't suposed to be lightning in the house! Once I could see again I saw the conectors we about done. I figure that was all because of a tiny little peice of metal or something in between the traces, good news is it doesnt exsist anymore. So how many volts/amps does it take to be leathal? 8)

The ninnys will tell you otherwise, but IMO it's pretty tough to kill yourself with just 100v. I've hit myself with 100v about a zillion times, and it's not that bad as long as it doesn't pass through the chest. That's kinda the name of the game in getting shocked, try to avoid it passing through the chest. You can take a hell of a lot of shock on one arm, and just have sore muscles in that arm. Sometimes even minor shocks that go from one arm to the other arm feel like they reset your heart. If you put on some latex gloves, and then a pair of thin clean cotton gloves over the top to protect the latex gloves from getting shreded, it seems to provide quite a bit of protection from shocks.

Also, I've held one lead in my hands, and stuck the other end of 48v on my tounge, and you get a mild tickle with the rapid prodution of hydrogen via electrolisis on your tounge, but it's hardly a shock. 48v on the skin is virtually undetectable. 72-100v is about the threshhold of getting shocked IMO.
 
Mind the amps men... or in this case the mA... It's the mA's that kills not the volts directly. Your skins's contact resistance is key, as is the path thru the heart as Luke mentioned. Left hand thru right foot and you end up in a wooden box. I am thinking of gloving my left hand as I work on these guitar amps... When you work alone, if you go over the edge, you cannot bring yourself back. It's a one way trip. I've watched a 2 inch spark jump to my index finger on my right hand from an unexpected conductive vacuum line on an ion source floating at 150 KV... it blew me off the platform and into a rack of gas bottles... It is on my list of the 6 reasons why I should still not be walking the earth... :wink:

Cool stuff I find my self wondering what the other 5 reasons are?
And in college I was told it old takes 300mA to put you down. I do under stand you should to try not to give it a path through the heart. But when conecting battery leads up it usual takes both hands. I have a better system now though. I hook my charger up to the controller and power it up then connect the battery and that gets rid of the Zaps lol.

My highschool had some classes on home wiring. The instructor's tip was to put the left hand in your back pocket when working near anything live. Not always practical, but reminds me to watch where my left hand is to avoid becoming a current path.
 
Hey Everyone,

I have a bit of a strange problem with my controller; I programed it this evening to change my speed settings for all 3 speed modes; and now i can't switch through all 3 speed modes after programming.. I can still program the main speed mode or the default one though.. any ideas why it won't go into the 2 other speed modes?

thanks
-steveo
 
Yes.
You have to set the speed mode

One mode allows you to change on the fly
The second mode only allows you to change at power-up

Watch.... Set your controller for low speed and turn it on - it will be stuck on low
Turn off, set to high, turn back on - it will be stuck on high

Toggle the speed mode

-methods
 
Hey steveo, Mine gets stuck in the middle speed setting unless I unhook the programing cable! I just cut the wires out side the case and installed a conector so I can flash it when I want and it wont be stuck in the middle speed setting.
 
Hey Everyone,

I have a 18 fet infineon, which i'm servicing for a member.. i have a few questions ..

If i install a .2500mohms shunt in the controller .. do i just set the cycle analyst in the high range .. set my rshunt to .2500mohms .. and i'm good?? ... will the cycle anlayst display accurate readings?

the problem ..

I was putting this controller on my bike for testing the shunt with the resistor for the .2500mohm shunt installed .. however i wasn't able to test anything .. i found something really strange..

The throttle line is all messed up!!..

it reads ... 0v 5v on the red wire & 5v on the yellow? bassically i have no throttle!

Anyone know why this is happening?

No. You must calibrate the shunt. I can grantee that it wont be 250uOhms. Probably more like 265uOhms or 235uOhms depending on if you leave the stock shunt in. Substantial error.

Also - you are going to reprogram the firmware for the shunt right? Otherwise the current limit could be >120A

Why would you assume that Red is +5 and Black is ground? :D

If the controller has the pigtails that I get from AllElectronics then
Yellow is ground
Red is brake
Black is +5V

If you have the controller open though you would be able to see that right?

Regardless - the pin configuration is correct and follows the Crystalyte standard - any off the shelf throttle should plug right in and work.

thanks methods...

dame wiring LOL ...

Hey Everyone,

Could anyone point out what resistor (I believe) I would have to modify to achieve a 84v cut off?

If i'm not mistaken .. I believe my controller .. with the highest Setting in the sofware cutts of at about 80v? ... i could be wrong ..

thanks

@ Steveo and Mike1

For regen at a higher voltage then 75 you need to make the LVC mod on R12. I have lowered R12 from 1.2K to 960R. This means the real voltage is the programmed voltage +25%. So 75V max regen voltage is now 94V.
See the last lines on my post and the right upper corner of the schematic: http://endless-sphere.com/forums/viewtopic.php?f=2&t=10312&start=315#p169765

The standard R12 value is 1200 ohm. Lowering the R12 value will increase the (programmed) regen voltage limit and also increase the (programmed) LVC.


EXAMPLE:
SAM-Pilot changed R12 to 960 ohm.
So if the regen voltage was programmed to 75V it is now actually 75 x (1200/960) = 93.75 V
AND if the LVC was programmed to 21V it is now actually 21 x (1200/960) = 26.25 V


Nevermind .. i figured it out ... Looking thought this thread is almost like looking though the yellow pages..


-steveo
 
Use the new 100V 100A Crystalyte thread.
The info is in the first few pages.

This is an awsome thread, I need to read ALL this sh..stuff! Sorry for the bump. But I just got one of these boards, got some work to do.

Peace, SS
 
Disaster, my 18 fet controller blew up. I wasn't even using it at the time. Rode a couple of miles day before yesterday and parked up as usual and put it on charge. Ignition circuit was off but main breaker was left on as it usually is.
Came to use it today and main breaker had tripped and wouldn't reset.

Here's the burnt bit.blown.jpg

This is a view where the B and C phase fets meet, near the large cap C201. As you can see the thick trace from the cap to VCC has melted.
What would have caused this? Shorted electrolytic?
