It tells the IC to stop boosting the voltage when no load is attached, without it the IC will try to boost the voltage til it fries itself :D

I have to double check that with other caps but it was on my desk so I gave it a shot :D and I can't remember how bad were they now, too much stuff on my mind, I will check it again tomorrow . :)))))))))) but it will work on the rectangular too, and on the hexagon one :D

Just replace the output cap with 22uF X5R and remove the one between LD+ and LD-. 10uF for the input is enough :)

and you get the internal optics which might be used in some fancy project :D

I think this thread went way off course :D

delicious :D:D:pop::pop:

Is this a spam? :D

No pots in that resistance range. Sorry :D I really would have loved to have some like that but they just don't exist. :D There are some tolerances that might affect the equation. Give or take 5% of the final value. I=0.25V/R +- 5% It might be 0.2V but most likely it's not. :D Some...

Great, I was thinking of making it double sided but I am not sure of the heatsinking issue. Perhaps I will give it a shot when I can order some proto boards. I am really tired of making my own etching. It's a pain for double sided :D

I am almost certain thats the AX2003 IC. Try leaving only the R150 resistor on and see what current you will be getting.

yeah I got mine in little box type and apply it with a screwdriver :D

a little paste goes a long way. Use little dips on the pads and it will do the trick.

I am not sure what you mean by tacky? :D anyway if that is the stuff that is like semitransparent paste then that is just flux that helps wetting the joints and makes soldering easier. It's already in the solder paste but when reworking or soldering on dry joints it's a must. I don't know how...

It all depends on the current that goes throught the diodes. Larger currents will result in larger voltage drop. It's not three for 445nm or four for 445nm... It can be 5 or 6 for 445nm running at 200mA for example. The more current the more voltage drop across each diode. Do some experimenting...

Kent you can get probably a little bit more than 2.2A in boost mode and around 3A in buck mode. :)

Re: Warning about LPF member "pr0jkt" Damn man, this really is baaaaaad..... :( Paypal always goes to the buyers side.... which is good for scUm buyers! They can say whatever they think of and paypal is on their side. A friend of mine sent a rare gold plated watch for about $1000 and the...

Hey luke, the OVP voltage by the TPS is 6.8V or 6.9V. I have already measured it. The caps don't seem to fail with a no load. Are those 6.3V caps? I think they can withstand the little above voltage at least for some time. What do you think?

Thanks Kent, here is another ones I took tonight, 3 days til Full Moon .... can't wait...... :D:drool:

You bet, Let me know if you are coming :beer: I am going to try a full moon on 2nd of August it's going to be full moon here. Sure hope there are no clouds :D

Thanks man, yeah I would have been cool to hang out with you :beer:
