Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR Just have the DMM connected to be sure, your factory default curent may be higher then mine so you can fry your LD. Do not push the current over 300mA for long. Set your DMM to amper meter mode. When you put off the back cover, with the...

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR And the second mod.

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR Here are the pics.

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR I am sad to hear that. You may be close as mine diode is even not heating up so much after a few minutes. How would I compare the optical output to others', can not I say okay some guy says he has 200mW and can light matches from 4 feet, so...

More info about modding the original driver is available in the 'Experiments & Modifications' section of forum.

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR As I promised, here it is. After bridging the diode (voltage drop on it is only about 0.5V) the stable current is 275mA (@6.66V total), because the initial 7.1V total drops to 6.6V in about 1 minute :( Otherwise it would be the nice...

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR THX, will try it and let you know the result, maybe with this and the 10 Ohm resistor already soldered there I can reach the magic 300mA :) I would not go for that current if I knew that I already had the promised 210mW output.

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR Sure, I have already ordered 2 pcs, but still I would like to find a workaround so the many other users do not have to change the driver anymore and even with 3.6V batts the output power may get increased by modding the driver...

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR What about to get out the 6V protection diode, this could get 0.7V more... Should it be simple desoldered or should both sides get connected afterwards?

Re: DX200 red orig.driver mod to 200mW+ w/ 3.0V CR I am talking about 300mA for the LD only because I have read that in the other's posts and I assume it can be close to the advertised 210mW output power. I have ordered mine from the UK not from DX but it is visually the same circuit and it...

Schematic would definitely help. Until it is available, you may try to decrease the 6.2 resistor + pot value to increase the current for the LD at standard 7.1V. Maybe the more current will not be all eaten by the circuit itself :( And yes, I ve read all the topics regarding DX200 but nobody...

No, you won't :) I am also from Hungary and the last order from DX arrived in 3 weeks.

Hello. Today I tried to modify the original driver to achieve 200mW+ with 3.0V CR2s. There is a big resistor as 6.2 (6.2 Ohm) on the driver. I have added a 10 Ohm/0.6W resistor parallel to it and voila, the original 235mA raised to 268mA stable, when using 7.1V total. No more current can be...

One can even push the output power higher by soldering a 10 Ohm resistor parallel to the big one marked 6.2 (6.2 Ohm) on the driver board. I have 235mA with the standard 3.0V CR2 fully charged, and after soldering the 10 Ohm resistor it went to 268mA stable, decreasing rapidly from 290mA. I...
