Hey Ads! Good to see you’re still around dude! :smiley16:
As for a translation, here’s the link to the site matic posted via the transation program babelfish:
Basically this guy has gotten the datasheet from maxim and put in the values for the resistors where needed based on the attributes of the Bit-CharG batteries.
He has made two chargers actually. One circuit is for charging a NiMH battery, the other circuit is for charging a NiCd battery. You can build either circuit, you don’t need to build both. Each circuit is based on a different charging chip, either the MAX713 or MAX712 respectively.
I’ve got some of these chips from maxim-ic just as Ads says above as free samples. I’ve yet to put a test circuit together, just too little time and too many projects…….
This is the circuit form the german page:
Looking at it closely everything is stock, ie: the same from the datasheets EXCEPT where it is detailed in RED or GREEN, these are the vaules you need to calculate based on the capacity (mAh) of the battery and how many batteries you would be charging, ie: single, dual/tri cells….
My only suggestion is that IDEALY you would need to put a switch in the car that takes the battery out of circuit (ie: disconnects it from the PCB) when it’s being charged. Otherwise you would have some current going into the circuit which would (theoretically) put the sensing circuit on the maxim chips off a bit. I dunno for sure, this is just my thoughts…..

Ok, here’s some more eye candy from the meet.
Here’s one of leonli’s chassis he brought to the meet. He’s got this simple but very effective anti-roll mod thing going on the sides of his dual cell beast!
Next we have Microamps’ modded 4chan controller with “extension sticks” lol….
This peak charger of Micro’s absolutely rocks! We all used it on the day!
Here’s mscharg-ed’s digi-q. Talk about small!
And here’s all our beauties! Too many to list!

Push those boundries!!!!
One thing a lot of us got into was taking our bits out for a serious spin in the dirt. Here’s the casualties of that little exercise.
I gotta say that Betty’s car shown below was the best car of the day! period! The way she handled everything was just beautiful.
Here’s micro’s dual cell 350A, nice bloody car!
Here’s my little TRUCK!!!
Even more pics will be posted (you got it, yeah!) Also gonna get some videos done finaly!
cheers(tired)

OK then, here’s some more shots of tha freaks in action!
Some more show and tell….
The offroad collection of betty’s and mine. Well basically, they’re all betty’s except for the single monster that’s mine. Also is an arse shot of leon’s palm runner clone Skyline…
Ms-charged trying to figure out if his digi-q i working. Like he should know by now, lol…..
So many toys…..mmmmmmm, toys…….
What are these d1ckheads looking at?

Dunno about you punks but I got myself fairly sunburnt! Let that be a lesson to staying outside for 2+ hours in the Melbourne sun!
I was a great day and we had lots of fun! I also got to make whip cream of microamps on the go-karts track. Matter of fact I shat on everyone on that track!:approve:
I’ve got to go out now but I’ll be back later…. Yes kids we took lots of pics and some mad video as well….
Here’s a sampler for now:
