Let me start by saying I have a small knowledge of electronics but nowhere near the level of a lot of the people in this forum, so I apologize in advance for any "noob-ness" or ignorance on my part associated with these questions.
I am trying to organize my first mod, in which I plan on using a dna-20. I would like to do a few odd things with it like installing 3 conformation leds for the fire, up and down external buttons I want to use. Please correct me if I am wrong but, from what I understand thus far is that the board uses "logic" for the fire button and that the button itself doesn't handle the actual voltage going to the load...(not sure what that means)
Does anyone know what is really going on here? is there just a small amount of voltage being supplied to one side of the contact like I assume? If so does anyone know what the voltage is? Is this going to be the same situation on the up/down buttons?
My plan is to use a DPDT fire button and dedicate one set of contacts to the control of the dna 20 and the other set to come off the battery to the led. Does anyone think this will work, and what negative effects could I run into?
The next problem I see is that the led I want to use is rated for 2.8v. I believe I can use a resistor to run the led with the 3.7 volt battery, is this correct? and will the voltage drop of normal use of the mod before the next charge effect the led?
I honestly think I am going to have to abandon the idea of using leds with the up/down buttons, but my plan was to use a extremely small relay (or 2) to control the up/down functions back from and back to the dna 20 as well a separate set of contacts for the leds. Do small DPDT relays like this even exist? I think I am over complicating this lol. It seems like a lot of work for something so small, but I would like to do it if possible.
Thanks in advance for any help or advice it is greatly appreciated!
