DIY Discrete Logic LED Countdown Timer

This digital countdown timer displays the remaining time set for a deadline/event. The USP of this project is that it is built without using any microcontroller unit. So, It is about going through a fair journey to hardcore digital electronics involving concepts of the clock, counter, and digital logic design: bit.ly/2UUYdmB

Really enjoyed this, great to see some discreet logic and breadboards. This video really could have been much longer demonstrating things on the boards as it went. Thanks!

[@mohak555]

Cool Project....amazingly explained 💯👌🏻

[@lazylad7465]

First time on this channel and subscribed because it delivered what exactly I clicked it for. Thank you ma'am

[@oldbutstillcurious3615]

Excellent presentation, many thanks - exactly the tutorial I wanted.

[@Davedarko]

I understood "let's get through it", but only because I have a big unfinished logic gate project that is haunting me :D
Great video!

[@patstandley5373]

One way to fix that!

I didn't know about this CD4060BE chip. Really useful to build clock generators from quartz. I just ordered a bunch of them, thanks for this!

[@andywest5773]

Great project! Nice to see some lower-level stuff than just SBCs and microcontrollers.

[@ayurrastogi3251]

Good explanation.👍👍

[@user-he9si6py4l]

hello! may i know what software did you use for this project?

[@sarvadnyadesai4962]

Wonderful Project...... its great to watch something built from discrete logic :D

[@thom1218]

I see some "Great Scott" influence in this presentation!

[@LATOZAROSSANTHONBSECEA]

Ty so much mam, im doing my lab atm, using ttl istead cmos IC, im using 74192 for DCB crcuit and 7447 for 7 segmnt display, i have this problem on designing the whole circuit to stop counting on 0 can someone help me with this?

[@dawsonzinza1671]

Good video. Thank you for the tutorial.

[@josefjelinek]

Cool.Just missing the soldering and enclosure building parts....

[@mcrogaming960]

Goodevening Madaam can I have the full schematic diagram of this project? Thank You

[@MAYERMAKES]

Great premiere! It was about time for a descrete logic project!

[@debojitacharjee]

can we use a AC oscillator used inverter to crrate a desired hertz and then convert the sine wave to square wave and feed it to the counter logic circuit?

[@thepeppertech]

You can certainly do that. But are you sure that your waveform is going to be that (quartz like) stable?

[@debojitacharjee]

@@thepeppertech That can be done using a NPN transistor NOT gate, isn't it? I am also thinking about creating the whole clock counter/decoder using only transistors.

[@1995yashasvi]

A Well explained DIY stuff. Great work by the mentor and the team. 👏

[@leandrobrunner1706]

could you send the whole schema please?

[@Jimseang2099]

Someone has the schematic diagram in PDF?

[@navadeep.ganesh]

Cool project. Gone full-stack with digital!

[@ChadKapper]

The link to the seven segment display does not work. Can you post a link to the product you used?

[@adiigeak8568]

remind me of my digital electronics class.
thanks a lot for explanation.

[@anitarastogi9454]

👍excellent video

[@olusatosin6887]

Pls, can the schematics for the whole circuitry be made available by anyone that understood it?

[@petergray453]

Subtitles please.

[@kaosthecosmicreviewer1055]

what was the value of the crystal timer?

[@OndryAulin]

2(15) - 32.768kHz

[@nishantkumar5816]

Good

[@shishiracharya4870]

What dees scratch mean?

[@partytempo]

To start with nothing and then build every piece until finished without any pre-assembled components. Like baking bread with water+flour+egg+yeast and not going to the market to buy a premade loaf.

[@shobhitverma2478]

I am the person who is always fascinated with electronics. I like to build the electronics stuff from scratch.

[@deh_developer2725]

Damn karnaugh

[@uvatham]

👍

[@smhedge]

Not bad, but to make it truly discreet, you have to do it with transistors instead of ICs.

[@element14presents]

Maybe next time ;)

[@billfield8300]

@@element14presents Actually very interested in a 'truly' discreet level clock. Even just a schematic would be great. But the logic and examples would be super!

hard to understand - india english :(

[@Hacker-at-Large]

Dealing with accents takes practice. Keep at it. I can say with some authority that her accent is easier to decode than a Liverpudlian or Geordie (Liverpool and New Castle England respectively).

[@Davedarko]

Andreas keep at it, you will get better at understanding the Indian accent, especially once your English improves.

[@element14presents]

Way aye pet.

[@petergray453]

@@Hacker-at-Large So true. That is why no company would ever make a video in Geordie.
