Today I take my time to explain the table of all basic gates. Anytime you face a project with your Arduino or Raspberries of any kind, you may be in the situation of measuring at the inputs or outputs of various packages. If these packages contain simple gates, instead of printing their specs, all you need is this table, together with the packages pinout, you can also download from my google dr...

If you just want to have all the six basic logic gates in one table, here they are. The seventh gate included - the XNOR - is a bonus, as an extension of the XOR. From a practical perspective, this truth table can become a real tool with your troubleshooting measurements. You can download a much better looking such paper tool - drawn in Altium Designer, thanks to my former student Alex btw, her...
The “NOR” gate on PLC contacts. Logic Circuits, 14/101
Просмотров 70521 день назад
If you already know the “OR” from the video #9 of the "Binary and Logic Circuits" playlist, the NOR should be easy, as it only adds an inverter to the OR output. In order to appreciate its value in diagrams, I included an application of what we call “negative logic” of the NOR function. The electric diagram looks extremely simple, two contacts in series. The tricky thing though is, that both co...
The “NAND” gate in very few steps. Logic Circuits, 13/101
Просмотров 57028 дней назад
Among all the basic gates, the NAND is surely the most used one, and present in practically countless electronic diagrams. The little application included in the video uses two NAND gates to “correct” / de-bounce µSW contacts. In my time, the professional keyboards were having “reed” relays behind the keys, so there were two NANDs attached to each key. For a standard 104 keys, this is equivalen...
The math behind the “AND” gate. Logic Circuits, 12/101
Просмотров 414Месяц назад
Well, all logic functions come with some math calculation attached. Luckily for the “AND”, what it does looks similar to the pocket calculator multiplication, so regardless how many inputs A, B, C,…N, this gate has, the Out= A x B x…x N. Really straightforward. Just to make sure, here are the two pdf pages as a reminder: AND_gate_description.pdf , Examples of AND gate packages.pdf : drive.googl...
The “AND” function, a marvel of simplicity. Logic Circuits, 11/101
Просмотров 534Месяц назад
If it was a coin, it was having the “OR” on one side, the “AND” being on the other. Maybe the most straightforward function, the “AND” is than making pair with the “OR”. The OR does logic addition, the AND performs the multiplication. How do you translate that into practical understanding? Simply by watching the app in the video. All elements are safety oriented, on no less than 4 levels. On th...

Well, not only as in the title, but even 1 1 1=1 and so on. Excepting, this is not what you hit on the keys of your pocket calculator when doing arithmetic calculations.

The 7.62mm and TTL ICs. Logic Circuits, 6/101
Просмотров 4202 месяца назад
Before NATO switched their favorite round caliber for small arms to 5.56mm, the 7.62mm was king. If I’ve got it right, the today’s flavor is 6.8mm? I am not a historian, and not skilled in ammunition details at all. However, after reading a number of books about the Integrated Circuits history, that unexpected coincidence looks still striking: how come the distance between the 2 rows of termina...
TTL Voltage Levels for “High” / “Low”. Logic Circuits, 5/101
Просмотров 4372 месяца назад
If you connect your voltmeter to an inverter package - or any other TTL circuit actually - you may expect the display to show you some clear value. For instance if the expected logic state is “0”, you may expect to see 0.0V on the DMM display. If the expected logic state is “1” or High, you are looking for 5.0V on the DMM display. In reality, as the power supply voltage for TTL circuits is 5V, ...

As great as usual. Thanks
@zakizaki1197 Thank you Zaki, you made my day with your comment😁
Awesome presentation! 😍
@SandyG-w4u Thanks for watching!
Thank you very much for your very informative and entertaining videos. As an educator, I'm learning a great deal of educational content as well as great ways of delivery, many thanks to you! Also, I would like to draw your attention to the idea that when you calculated the resistor dissipation power you multiplied the current by the resistor only [40:11]. I think it should have been the current squared multiplied by the resistor, right?
@ihhazmi I am very grateful for your remarks. Thank you for your sense of observation. In the enthusiasm to do the calculation too quickly, I should have noticed that. It escaped from my attention to multiply the amperage times the resistor voltage, not only the resistor ohmic value. The resistor voltage was in the adjacent column -if you take a look in the attached doc "10mm_LED_test_and_distroy.pdf" and I just missed it, sorry. Your observation is right, thanks again. Cheers!

Good work 👍
mWh/h is the right an most valid value. The DC/DC converter makes a higher voltage output. This makes it difficult to calculate the mW/h compared to a accu without this converter. So the mAh value is useless to compare the power of Lithium an NiMh accus.
Great video for people getting into microcontrollers or hobbyist electronics. There isnt a lot of info out there on the net that goes over this info in the context of batteries specifically, only in the context of general circuits. I would suggest that you take the time to cut out things like taking and finding the photo on your phone and possibly put the photo in the video. I really like the pen and paper plus talking format that you have used. If it's unscripted, you also did really well at keeping the information on topic. In any circumstance, don't be afraid of or averse to writing a script or to do multiple takes and cut takes together. Other than that, great video! Also, you went over power at the end in relation to the amazon listings; it may have been worthwhile to present that info earlier to show how the battery types compare to each other. 1mAh at 1.2V isn't the same amount of power as 1mAh at 9V or 8.4V; you'll get the 1mA for an hour in all circumstances but if you had voltage converters in a circuit with all three types of batteries to make them all the same voltage the current draw on the battery would change proportionally to the output voltage. I know you know this, I'm just saying that the audience for this video may not connect those dots even though all the info needed is actually in the video.
Very pertinent comment Brenden @ProjektEpic thank you! No, my comment wasn't scripted, I just highlighted on my notebook the general points to talk about, as I manage the subject anyway. My main doubt was about the length of the video. So I decided to cut it short to keep it below half an hour. Also realised that developing to extend it over half an hour will challenge the watchers' patience. And I agree that maybe I should have kept it more on the rechargeable "9V" battery. I always try to stay on the subject, and my goal was to get the attention of the potential users of the 9V batteries over being consistent when comparing numbers... Thanks again and receive my best regards
good video
If you dont have the plastic connector, the pins are set on the ribbon cable side to be exact sizing for a 2.54mm header sizing, so you can just have a 4x10 and place 2.54mm headers on both sides and it should plug directly into the headers allowing you to plug in either a 20 pin or a 16 if you want. You dont need the mounting bracket itself. Also, I recommend you add moisture to fiberglass when you cut it so you arent inhaling fiberglass particles.
Thank you for your feedback, I value others' opinion. For the first observation you've made: surely you can find a different way to connect a flat cable on a breadboard. Here is a link to an adapter without the plastic case: abra-electronics.com/interconnects/connectors/headers/male/2104-ada-idc-breadboard-helper-2x8-16-pin.html Working with beginners for a long time, I noticed what - in my opinion - is the advantage of using the plastic case and soldering the headers along the two rows. Both the connector on the cable and the plastic box have a notch, so reducing the chance to plug the cable wrong way. This is why I chose it. As for the second observation, you are perfectly right, especially if you have several pieces to cut. For the demo, I only cut one sample but yes, I could have given your advice as well. And for cutting fiber PCBs more often, a better protection would be to wear a mask. Have a nice day and thanks again!
I don't understand the reason of the length of this video. like 8 16 and more segments are the most basic electronic you can find, it's on or more LEDs by segment, you connect the led to the right voltage the segment is on, you disconnect it it's off. Also using a 16 segments to display only 8 segment is a waste of money, the price difference is very high.

You seem like a man I could be a best friend with
the access to the google drive looks restricted. Can you do something about it?😮💨
Very ingenius. Im assuming that specific printer has a ethernet port on the back that would make it easy to share the printer with PC's on the same LAN. Im waiting to see how it will turn out!.
Thank you Cesar for your feedback! If you watch 🎥the video clip again, you'll realise that the little project staying between the printer and the two computers is connected to all three devices by simply using their USB ports! Surely more details are on the way! Regards
@@CU_Wiring_Electronic_Projects I meant that the same could be achieved with a LAN cable that can make the same printer usable with other devices on the same LAN via IP. I see this project being useful as a mean of avoiding the device "Calling home" and creating back doors due outdated firmware.
Thanks again Cesar! Excepting for industrial printers where proprietary connectors were employed-I had to build some interface to use such a printer with standard PCs - there are 4 classical ways to connect printers to PCs: #1-parallel cable. This interface is now obsolete, typical for the old style "Line printers", Centronics connector on the printer, DB-25 on the desktop, with LPT1, LPT2, hex addresses 0378, 0278. #2-USB cable: USB-B on the printer, USB-A on the desktop. This USB was designed by the manuf. to allow local hook-up to a desktop. This is also what the present project does btw. if you need to occasionally hook-up a laptop too to the same printer and you don't want to keep removing cables. #3-RJ-45 Ethernet connector is the one you refer to. Big companies or institutions can share printers among several users. Not very practical at home because you have to draw cabling around. #4-Wi-Fi, which is the modern way trough your home router. Older printers won't be provided with. Conclusion: I actually use this little project just as a prop, to make people familiar with PCB relays, as an app to share a printer locally in the same room between two PCs. Regards
Thank you 🙏
Very good explanation and presentation. I assume, the motor stops under dynamic breaking mode. I am wrong?
Thank you Mariana, I'm flattered by your comment. As the PLC lab was organized in a very limited space, the three phase motors run freely with no load so no need for dynamic brake. However, there is another lab only for motor control purpose, and there we attach load and apply dynamic brake to motors.

I take it thiis a preview video? Any chance of providing links - is it a DIY project or just available pre-assembled?
Yes this is a preview video. I'll put my assembling video online on Thursday March 9th, then I'll process the video two of my students made when assembling the kit themselves. If you need any info before Thursday, let me know. And thanks for your feedback btw!
nice but not really a new thing we DIY'ed these things back in de 80s and 90 to f.u. some people hahahaha
Surely the idea to shut off a TV-set is not new. What is interesting however is the size of the project, because the codes of about 115 TV brands are embedded in the 8pin microcontroller. So making the little project very effective. And anyway, the projects I am presenting are not here because nobody saw them before. My goal is just to encourage people to make such projects-smaller or bigger- to improve their troubleshooting skills. And btw, I am very grateful to you for taking a minute to send me your feedback.
