Re: Corrugated conduit to hide wires

How wide is the stand between model and base? I would think a long piece of shrink tube would coral your wires and fit nicely down a hollow stand and be flexible.

Re: PCB design

Failing that, you could use a small breadboard, 170 points/ties at a size:1.85*1.38*0.33inches.

I kept thinking and how about this? https://www.sparkfun.com/products/12702

A solder-able breadboard.

Re: Micro Electronics Soldering Station

Check out reviews on amazon. Do you just need a station or the iron as well. A 20 watt iron was not hot enough for me. I'm also using non leaded solder as well so a hotter, variable temp iron has worked out better.

Re: Powering LEDs without resistors

Or buy pre-wired leds and smds that have a resistor already soldered in at specific voltage values.

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. Well, I still don't understand it. Plus, I cannot get it to work the way the instructions...

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.

Diode: 1N4005 Why do you need this? It's a rectifier to control high voltage surges from what I am reading.

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...

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.

looks like this.

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.
