Lee torch came apart very easily; the main mechanical components can be seen below. I wanted only a couple modes and wanted to get rid of the SOS and Strobe functions. Kindly do publish the range of applications the circuits support, and also any more additions to the circuits with regards sottapilla.
Small micro SMDxt package together with minimum number of external components is a best fit for handheld devices. The markings on the IC indicate it is a CX Electronic component search and free cx285 site.

The torch appeared to be mechanically well made, however after inserting the battery it became clear that it did not work. With a battery connected I checked the voltages at various points on the circuit board.
Removal of the cap which measured 2uF once out of circuit had NO effect on the mode cycling. There are many controls available for audio synchronization to get desired lighting effect, including gain, speed, and different filter settings.
Flashlights and Parts WTS: Results 1 to 17 of I simply machined my own collar, press-fit it into the host and make sure the collar is tight enough to fit an AMC driver.

How to disable mutli mode on this driver driver pict included Well the answer in short is yes. I came to the conclusion by experimentation that the cx2895 change you can make is to make the driver board a single high only. How to disable mutli mode on this driver driver pict included I tried playing with this cz2859 issue myself 6 months ago for the same reasons. If you can find a datasheet for the CX IC, that would probably help.
Image resizer by SevenSkins. I was very sceptical about how good the torch would be; with such a low retail price cost the BOM cost would have been pennies.
It should always start on high with this mod. How to disable mutli mode on this driver driver pict included Hi! If so then I may use a heat -sink. Different lighting patterns and blinking sequences can be programmed to driver registers. All times are GMT Hence it is not possible to drive beyond to mw LEDs.
Last edited by m4a1usr; at After waiting 3 weeks the torch finally arrived. As always, you get what you pay for! How to disable mutli mode on this driver driver pict included You could try drawing a pencil line heavily from one end of the capacitor to the other joining the shiny ends.
It emits a spectral band of radiation at nm.

Unfortunately everything seemed fine indicating that it was likely to be the driver IC that was faulty. Leave a Reply Cancel reply Your email address will not be published.
The circuit can be powered from two torch cells connected in series. You might want to check out this thread since it appears to have a driver that might work in your application.
