The mistery of the Dilda circuit.

oh lol, you're in Europe too, I said you because I forgot you weren't in USA.

sure.. ill test it out with 6V and 7.2V and measure the current comin from it. ill try to get it done by tonight

edit: ok.. i took the readings. ive messed with the pot before but at 6V its 227mA and at 7.2V its 305mA

Thanks for your time, but what I wanted to know is if in your circuit the current draw from the battery equals the current at the diode

ooh.. my bad. ill retry

If for you is not a problem, can you please try also another thing ?

The voltage at the sides of the 6.2 ohm resistor, and from ground to the reference pin, in both the conditions, 3 and 3,7V batteries (or 6 and 7,2V, if you use a power supply) ..... for see if this can influence the loopback/reference part of the circuit ..... just trying to understand why it vary, and this can be one of the reasons.

Ofcourse, if for you is not a problem and don't cause you difficults ..... if you can do it, i marked the points on your image, for more easy operations (for the reference voltage, is more easy to measure it there, than from the IC pin).
