555 timer Timer

Click For Summary

Creating a 556 timer using two 555 timers is indeed possible, as a 556 timer is essentially two 555 timers integrated into one chip. Users can wire the two 555 timers to function in a similar manner to a 556, allowing for dual timing applications. This approach may require additional components for stability and functionality. While using two 555 timers can replicate the 556's capabilities, it may not be as space-efficient. Overall, utilizing two 555 timers can serve as a viable alternative to purchasing a 556 timer.

Thanks

Yes. A 556 is simply 2 555s in a single chip.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
