yeah... if only my order for the tekgems drive had gone through :'( :'( :'( do you know any examples or schematics where someone has done that with the opamp or sensing ic.?

for sure. Sooooo moving on...... high side amps, or something. Used to allow a negative ground so u can heatsing the diode ( case is negative) I dont understand how to incorporate one into woops schematic, or anything for that matter. or when you cannot ground the case..... or why. anyone know...

i love you guys!!!!!!!!!!!!!!!!

half toked, half....

wow, you are pro. I get it now, and partially from what I thought. The 100v globe also has a much higher resistance then.makes sense. Were you like this when you first started learning..??

like magic..... its just weird because i think of a power supply, like ones i have, that i set the voltage, and that is what comes out, but with these, you can set it to step up and it goes to the right voltage. I just misunderstand how you can have different voltages, for the same current...

Re: Options for Lenses I appreciate your help. But I will be making my own heatsink, meaning I will be using a metal lathe to mill a round aluminum cylinder with a hole and set screw for the diode. I just need to know the size of the lens casing. So I cant use the aixiz housing or lens because...

Oh IgorT... I know that I'm not dumb! I am confused as to how, when in constant current, you can drive a blu ray diode (5V) and a red (2.5V). What is deciding the voltage for the diode. How come when you attach the blu, to a red setup, it doesn't feed it 2.5v, or does it? Does it just figure the...

oh god, that sucks. i think im like half swedish. EDIT: yeah thats what my dad said. sweet. so wheres everyone from?

What are my options for lenses? All I see is the aixiz acrylic or glass, or a merideth. I just need the little metal enclosure, and the lens, so that I can put my diode in it and make a heat sink for it. Can someone give me a summary of the different lenses, and their size or use. I know their...

oh, im a little white kid.

Oh thank you so much I completely get it now. All I needed to hear was But I thought of another questions while I was trying to sleep last night. Supposedly, you can use these buck boost drivers to drive a blueray, or a red. Lets assume blue is 5v required and red is 2.5v. If the chip...

WTF kim jung whoever denied me! refun! BOOOOOOo!... And i thought i was getting in on this... :( so sad now. hopefully some way better deal arises :( :( ahh :'( :'( :'(

resize it but change the dpi. but then you have to change it back for the printer... so just dont resize it.

:( I just cant put together how the CC works. Only sort of. Anyone care to explain it more. I read the datasheet but it only explains voltage regulation and I barely understand that, let alone understand the logic of how it works to apply it for current..... Sorry....

alright i completely understand now i read a little more. the chip cannot just do it by itself, inductors are hard to incorporate into semiconductors, so they make you add your own, and so you can change it. its required for the chip to work and thats how it works, thats why its called a...

yeah but you have to trick the vreg and that uses voltage unless you use a high side current sense amp which pretty much eliminates it. i want to try to modify this schematic by woop to run with that amp, he said hes going to do it but im impatient. :D anyone want to help?

no way thats your name amk? thats sweet! and greg stoner is a sweet name! lol my name is boring common swedish name. erik.

the first chip i posted is gonna work out failr well i think. it will make things MUCH easier with the current regulation instead of tricking vreg. the only problem i see is its step up only, so less efficiency than it could be, but still pretty high. but you can just put batteries in parallel...

hey so while ive got some knowledgeable people here I had a question. Where can I get a "normal" lens with case. What I mean is not the crappy aixiz lens, and not an expensive merideth glass lens. Pretty much the merideth lenses, but cheaper or something, I like their little cases, but theyre...
