Sorry, I hadn't read the forum post. The original circuit will work, but it *will not* drive LEDs directly (and that'sa bad idea in any case). Build some buffers to drive those LEDs.
You can't connect and LED between the output of a 40-series chip and ground and expect it to work well because the chip can't source enough current. You'd need to connect it (with a suitable series resistor) between the pin and +5V and then arrange to turn the pin *off* to turn the LED *on*. The reason for this is that the output of the chip consists of two transisors, one to +5V and one to 0V. Due to the way the chip is made the one to 0V can turn on harder than the one to +5V - a bit like the difference in strength between your bicep and tricep muscles.
Now, go build a simple logic probe and get that first circuit working, because it *does* work. The point about 555s being utter shit still stands.
