? Post # 159 = yes.
On Stream #2, C1, 555-2 is .2 uF. Either 74LS164 or 74HC164 will work but as the LS has poor high output
it was wired as low side output with a disadvantage of if the Clear is low, all LED's would be on. Not a problem
if Wendy's timer-power control were used. The 74HC164 has = output drive high or low so Stream #3 is configured for high output V, making Clear available for logic disable.View attachment 100344
Wow, how is it that both of you know so much about electronics? Are both of you like professors? I'm such a beginner so I am happy to learn from both of you. My background is commercial photography, welding, powder coating and cooking. Especially BBQ! I just love building stuff. I want to strengthen my electronics because that was my Dad's background and chemistry. Thanks for taking the time to help me out.
