I forgot to consider internal resistance of battery, been using bench power supply at 1.5 V with 3 amp limiter.

http://www.mouser.com/ds/2/90/LEDModules_LMH2-275215.pdf here is the led I have been messing with. I powered it up from power supply and the current draw was 350mA. I only need ideal components.

Wanting to know if it is possible to power a LED with a forward voltage of 29.3V and forward current of 440ma from a 1.5V source with a 2400mAh Capacity? No particular need for this, more for challenge/knowledge. Have tried methods with a transformer, DC-DC converter, and lm350 constant...

HAHA, thanks, had a feeling it was going to be something stupid. Lesson learned

not sure why I am getting a syntax, I am new to programming so trying something simple. Can somone please explain why I am getting this error? int LED = 11; // on/off battery 2 control int LEDP = 5; void setup() { pinMode (LED, OUTPUT); pinMode (LEDP, INPUT)...

Great advice man, thanks.

Thanks, Ill check it out. Wouldn't I have the issue of someone running off with the idea though?

I see what your saying, and I wouldn't have the mindset to discredit someones skill or undervalue the need of the programmer. My field is in electronics, if someone came to me and said they had an idea for an electronic device and they needed me to build the circuit with the incentive...

That is a good point, maybe contracts and some legal terms should be placed. That is crappy people can be like that.

Even if I'm asking for a partnership which means you would be getting 50% of whatever revenue it brings in? and I handle all the funding and marketing? This would not be a for hire position, so no one would be getting paid during the development stage, nor should they quit their day job. I...

So I have no background in web development. I can build a blog or an online store via wordpress. but let's say I want to build a "sort of" social network. I would not even no where to start. Would it be a dumb question to ask a pro for partnership if I handle the marketing and funding? If I was...

yes, I forgot I reset the o-scope to its default settings, the 10x probe was the issue. haha. thanks. to get I have rid of the ringing, I added a capaccitor filtor to the source input. attached the new signal output

Jim Hardy that was a great and helpful explanation, thank you. I am using a CMOS. so I increased the resistance and the components better match the formula now. also the pull up resistor had no affect. I did however ad a capacitor from source to ground to filter noise, and that help clean up...

I have reconfigured the circuit. It looks a lot better mathmaticaly. But just for fun I am going to try a pull up resistor with a 10K pot from source to output. I have checked the connections multiple times and even reset the scope. Ill have to try these new things a little later when I get...

No I don't have a pull up resistor, but ill try it. I wouldn't know what value to use though
