NiMH/NiCad Charger

I found this charger at...

http://digilander.libero.it/mircose/elettronica/cbat819/cbat819.htm

Somebody tried it? Looks cool...

I made a PCB in my spare time :D

Is site in Spanish? I could not get a good translation...with bablefish

was the source code available??? my nicad charger needs a 16 bit adc to handle the battery range I want...1-15 cells.. or some magic way of measuring the dynamic voltage change when charging 15 cells...
10 mv with 10 bit adc and 25 volts is hard to see....

It is Italian...cannot find the guys e-mail address...also no source only hex.

Hi off topic but ...
If you cut a main title from the main page and past it into Google it will translate it all :).
I.E. "CBAT819 Caricabatterie programmabile a microprocessore"

Much quicker as well.

I tried to program the pic but it does not pass the verify test probably due to my programmer.
I would like to know if it is the same for you.

hadihf,

Can you post your lay out PCB?
What type of toroide it use? I didn't understand.

Hi all,

I have built this charger but it's not working properly.
Charging 2 NICD, power supply 12 volts and charger set in 500 mA.

Power supply indicates 250 mA and multimeter between charger and batteries indicate 370 mA.
Voltage on LCD has some oscilation (0.1 to 0.3 v.) and current has some oscilation too.
The charger detect peak after 5,10,20 and 30 minutes.
The IRF 530 becomes hot, burn the fingers if I try to hold it.
For L1 I have used a toroid with high permeability and only 30 turns to get 2 mH, I don't konw if it is acceptable.
Anyone can help me, pls?
