Re: Why is my 555 timer not blinking?
I ain't no Geordi and I figured it out from the same link that I posted above. I think you have to watch out for polarity. If it doesn't work lined up in one direction, turn it around and try it the other way.

Re: Why is my 555 timer not blinking?
1N4148. It's in the link I posted above, just scroll down to duty cycle stuff.My circuit with it has been working fine for 2 years.

Re: Why is my 555 timer not blinking?
Does anybody have any comparison diagrams for monostable vs astable? This is new to me. Incidentally, was just farting around with this stuff last night on my breadboard, trying to get a strobe to work. I am able to get an LED to blink, but not strobe. Like, the off time resistor was a 120k or a 20...

This is my 556 timer. The signal diode is a 1N4148. This gives me about a 1/10 of a second on and 3/4 second off.

Re: Why is my 555 timer not blinking?
Diode: 1N4005 Why do you need this? It's a rectifier to control high voltage surges from what I am reading.

Re: Why is my 555 timer not blinking?
Hope my picture helps. Ignore the trim pot to the bottom right as that fades my torpedo tube for my d7. http://i.imgur.com/LFO41ur.jpg Additional thought. Are you trying to make a strobe blink? I use a signal diode in parallel to r2 for strobing, which gives the short duty cycle. No diode if just go...

Magnet wire is what you are after. Check Boyds' video again. I saw it as well.

Re: How do I strip WG28 wire?
look for wire stripper that can handle smaller gauge. I picked up one a few years ago that goes to 30 gauge.

I'll assume you are using 3 or 5mm LEDs, probably white and as such likely require 3 to 3.4 volts each. 2 such LEDs in series would require 6 volts to get them to light nicely. ( 3+3=6 ) I use 330 ohm resistors for my projects, though I usually see others using 470 for protection. 200 won't be havin...

Best bang for the buck LED double density strips?
Looking around and so far this seems like the best price in north America.

With what do you secure LED wires to your model?
So far I have only lit a d-7. I glued the LED in place and let the wires lay where they were. I am working on the 1/537 refit and trying the Raytheon effect. So far epoxy as well as lepages' ultra gel super glue have failed to hold the led/wire in place. What do I need to use hold the LED and wiring...

Use your basic layout for making a nav flashing led and then put a signal diode (1n4148) in parallel with R2. It works well. Picture is in this link.
