An up/down counter can indeed be constructed using only JK flip-flops, as mentioned by a lab TA. The discussion highlights the method of creating an up counter by utilizing the Q prime output from one flip-flop as the clock input for the next. Participants are encouraged to explore additional resources, such as a specific document on counters, to gain further insights. The complexity of designing counters is acknowledged, indicating a common challenge among learners. Overall, the conversation emphasizes the feasibility of building an up/down counter solely with JK flip-flops.

So as an aside during class my ECE lab TA mentioned that you could make an up/down counter using nothing but JK flip flops, we've already done an up/down counter using JKs, AND gates, and OR gates, and I understand how you could make an up counter by taking the Q prime from one flip flop and making it the clock for the next one. Is it possible to make an up/down counter using nothing but JKs and if so how?

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...
