I noticed there are no CLR's on the LED's. Does the IC75154 somehow limit the current to the LED's? I'd like to make this out of wood with a bunch of LED's I have, but they are all 3V-3.2V only.
You can refer to the 25 LED chaser circuit video by this guy. You have to use 2 4017 ICs, and stop the second one at 2 And use the 1hz circuit instead of 555 timer, and you'll get perfect timings
From local market. 100 rupees each (1.35 US dollar). In electronics market, it should be around 70 or 80 rupees. Not all components are available, for some uncommon components, I ordered them from Amazon.
@@EEWave wow. I wish we had that kinda stuff locally. I live in a small municipality on the east coast of Canada. The closest city is 5 hours away and they wouldn't have a place to buy ic and such locally and if they did it would cost more than I already pay
I had this exact idea few days ago. Didn't think it's practical. Now I have proof it isn't practical. I was thinking just cascading 3 4017s for minutes, and one set of LEDs would represent 2 minutes. And 2 more to show hours. The hand configuration was exactly the same as yours. I don't remember what I thought for seconds.
74154 is pricey in Canada man. Like 4 bucks each. Is there a replacement I can use?

Circuit is good and best keep it up, bt what's about 1,2,3 and 4 minutes?
how to count up to twelve seconds with this circuit? I want to install the led from 1 to 12 seconds

Incredible
I sucked it up and ordered 5 74ls154 demux chips. 5 dollars each haha also a pack of 74ls92 ic lol
Very costly
@@EEWave where do you get your parts and such?

Please share the circut digram
Circuit diagram is in the video
Your accent is like VIRUS of 3 Idiots.. well jokes apart great efforts. Thanks for sharing such information
Wow, thanks
