I am looking to purchase a linear LED circuit board for making LED strips. So far, I have found only one dealer for this item, and I am pretty...
Well the pad itself lifted up, I assume it was removed from the trace.
Is there a way I could scrape at the pcb to expose a trace and solder it...
So I did a volt mod that required me to desolder a resistor, that that I did successfully, then solder a 50K resistor in its place.
Damn..that LM555 carries some pretty advanced circuitry..out of my league
Alright then. :)
Ok, I have a switch that opens and closes a circuit.
I want to make it so that, with the push of a button, the circuit is opened for about 4...
Good idea..I may have a go at that as well. I do have a 1K pot around here..
Yeah, they're 5mm.
Fine, I will look for some 120ohm resistors.
I see what you mean, but my LEDs are rated around .03-.035A
That gives me a lower resistance value.
My 50 Cent game did not work :(
Thanks anyway Bit-Tech!
Strange--I have the same LED specs as you but it is telling me I need a 60-80ohm resistor.
I guess I'll just get something around that...
I'm guessing it is better to use strips of three than four for reliability right?
Then I am confused on you reasoning for an 85ohm resistor....
By 85R, I'm guessing you mean 85 ohms?
Why not do series of four in parallel and like a 1-5ohm resistor?
Well, I can't say I got "good" LEDs, they are the ones you get for packs of 50 on ebay for $15.
I tested a few and they seem to work just fine...
I am going to be lining my case with this channel metal:
I plan to drill a number of holes in the metal and place LEDs in them.
very cool little things, but the servo controllers are about $75 :\
a bit out of my price range..
No, I just need the servo to push the LCD out and as it comes sliding out of the bay, it is also falling down. The LCD will have some roller...
And what would that help? For some reason, people are telling me to un-modify my servo and limit the rotation lol
I will have no problem un-modifying this servo if that becomes necessary.
The LCD will just slide out , gradually falling downward by the force...
