If you want an inexpensive source for large versions of the magnets look for "dead" hard drives. You need to tear them apart CAREFULLY however there are usually 2 large magnets in each drive.

It is entirely possible the wall wort was not supplying clean power.
This could have caused damage to other components.
That might explain why the 555s keep frying.

I think I understand the question. I am working on a similar circuit myself. If I understand correctly, you need to determine the frequency and the duty cycle. Using Kylwell's input as a standard if you set the frequency to 80 htz (72 + 10% approx.) as you reduce the duty cycle to give the impressio...

John, Can you define "too slow". IIRC anything over 15 cycles per second is going to have issues. If you are running slower than that it could be a duty cycle issue. If the LED is on over 50% of the time there will also be and issue. Any details .e.g. the basic circuit (555 or PIC) would also be a h...

As a last resort, find a smooth wire smaller that you want the hose e.g. 12 or 14 ga. house wiring. Wrap the outside with smaller wire e.g. 18 or 20 ga. couple drops of super glue along the way, quick paint job and viola.

Just a suggestion, and not the best one but it should work. I assume you are using pins 1 - 7 , 9, 11 and 12 as the count pins. Cascade "OR" gates and an inverter so the output goes true when all outputs are low (0) and use that signal to drive the 11th LED. Bit of a pain and there is a way to do it...

According to the national standards 28 ga. is good for 1.4 amps (1400 mils) 30 LEDs should draw around 600 mils, "room to spare". If you are using a wall wart check if it can supply that much current.

Are you really planning t install 500 leds in one model? At 20 mils each thats 10 amps. 20 guage would be needed to handle the load. That also means you need to vent the heat created by 50 watts of power. Check your power supply also, a wall wart isn't going to handle that kind of load. If you are o...

If it is a straight edge I vote with the score and snap method.
But score deeply and snap it over a sharp edge or place the score over a large dowel e.g. broom handle and press gently, work your way along the "break".
