Thanks man, I've no words to explain how you helped me. I'm brazilian and I don't understand english so good, but your way of speaking is easier than all the other people. Oh, +1 subscriber
Great video and great presentation style - so easy to watch and listen to. I wanted to know how to use a 74HC04 and now I do. I will be back for the other 74 series chips. Thanks
PAUL can you make video lesson on giving a bunch of examples of using the ADD & Subtract modes on Oscopes and examples of using the EXT external trigger input port on Oscopes. I needs a lot of examples to know how to use these things on oscopes
hello. I been working on my alternators. I checked the rotor coil resistance. it comes to 1.8 ohms. I I don't know if I'm right but I figured it would pull about 6.7amps max. at around 11.9 volts. the voltage can range from 10-14.8. give or take a 1/10volt or two. so what would it pull with 21-29 volts. I kinda think I remember how to do the maths, but there's always the uncertainty. be cause no one has ever said. THIS is How its done. and this is a example. great video. I been thinking about shift registers. are they coming? I had a idea for a lil project. with them and a 555, and dome LEDs and FETs.. I don't have a clue about the inverter. how I could use them anyway. thanks ...
+Robert Gibbons Well the HC are high SPEED CMOS logic. The older LS chips used TTL logic. In my opinion the benefit of the HC is it can be powered by a much lower voltage.
at 8:40 when you charge the capacitors what happens at the negative side of the capacitor does it become a -5 or +5 if the answer is +5 then why does it allow DC ? I have learnt that a capacitor allow AC and blocks DC 😧
I really enjoy watching your videos, but I don't have an oscilloscope, so I can't tell what's going on. Ralph Bacon made a video about the logic analyzer. Can I use that instead of the oscilloscope you guys use?
Obviously you have a computer, hence you could have an oscilloscope. Sure, it is pretty limited, but it is sufficient for the low voltages and low frequencies of this video. It is freeware and uses the soundcard of your computer. Download it from here: www.zeitnitz.eu/scms/scope_en?mid=4.01 Peace... - and have fun!
Just had this idea of making these different logic ICs with transistors on either separate breadboard or perforated board with transistors. duckduckgo.com/?q=perforated+board&iar=images&iax=images&ia=images en.wikipedia.org/wiki/Perfboard Paul already explained logic gates with transistors ruclips.net/video/j4wUERSXQs0/видео.html I dunno, if it is doable or not. And maybe using SMD parts would make it smaller. I guess it is simple in the cases of NOT/AND/OR but I ain't sure about the rest. If one making on separate breadboard, it is better to use tags(some paper like posit note) or a tiny paper stuck/fixated by jumpers then write the pin numbers just like the IC design, maybe obtained from Datasheet. www.futurlec.com/Datasheet/74HC/74HC04.pdf If making a perforated board make it so it stands upright and give it some male header pin. Then make another tiny perforated board(cut the one you need to) with same size as an IC and with both female header pins on top and male header pins on bottom with connecting wires. Just like what this guy did ruclips.net/video/9QZkCQSHnko/видео.htmlm34s Also mark the pin numbers just like the IC. You can put a masking tape on the female head side then write the pin numbers. en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits Good luck

I just started a Digital applications class. And I just found your channel. I think you'll be helping me greatly!
This is going to be a good series. I'm looking forward to seeing what becomes of all these 74xxx ICs. Thanks, Paul!
The inverter, a good solid start. This may end up being one of the basic lectures on ICs I have been looking for. Thanks
Great video and great presentation style - so easy to watch and listen to. I wanted to know how to use a 74HC04 and now I do. I will be back for the other 74 series chips. Thanks
Interesting. I'm interested in making this charge pump.
Also, I learned that there's a series available as kits. Thanks for sharing.

Thank you!
what is a good first project for the 555 timer before I start integrating it into something like this circuit, or should I just go for it?
Thank you for this vid
It is a thump up vid
I joined your channel
I wanna ask what is a 7 channel hex inerter,
good stuf...
have you ever got an electroshock?
7400 logic ICs are loads of fun, when u finish explaining all of them can you build 8 bit computer ??
+Frank Alvarez "all of them" is a heavy load. Let's go with "many of them" and yes, 8 bit computer is the end game. :)
Glad to hear that :)
learnelectronics least hoping you would say that.
Certainly getting hit with are now Paul!

+James stranger yep74hc595 8 bit shift registers...we will get there
great thanks from Azerbaijan! very help me this logic ic information to use H MOST---dc motor control with ic L6384E.
Very interesting. Those are HC. How do they differ from other 74 series or the CD chips?
+Robert Gibbons Well the HC are high SPEED CMOS logic. The older LS chips used TTL logic.
In my opinion the benefit of the HC is it can be powered by a much lower voltage.
Is this a nor gate?
THE VOLTAGE REGULATION IS LIMITED WITH CHARGE PUMPS?
why was this soldered on my gameboy pocket's light attachment?
