Footprints for connectors are not specified?

thank you so much for your KiCAD guide video, it really helped me a lot!♡

Am I right with my guess that a bipolar transistor is used instead of a small mosfet like the BS170 because the driver transistor's switch time doesn't matter much compared to the power MOSFET's switch time?

In the Fast Push-Pull Circuit, are the push-pull transistors backward in their position?

dont forget these are inverting circuits so will apply full power to the 4.8ohm load when your Arduino is switched off ! or when the input is zero volts !

you wait for mosfet driver circuit then three come along !

what is the software you used? i like it

To my surprise, I found from digikey some P-Channel mosfets that don't cost that much but are similar to the N-Channel RDS(on) levels. E.g. G040P04T has less than 3.7mΩ and is only $1.82. The G050PO3T has less than 5mΩ costing $1.17.

Very cool, I wonder why they didn't continue this feature into Arduino IDE 2.X? Either way it seems useful for running on linux live USB systems without internet, which is a scenario I use often. Thank you.

This is very creative and the video is very clear and well put together. Thank you very much, this is exactly the kind of video I wish there was more of.

very well explained, even though i am in mechanical field and learning electronics now. i can understand your video at a good pace. Thank you very much.

My God, this is actually really easy - I've been putting off using PCB software for 20 years but recently I have genuine need of it and thanks for making this video!

Coming from Eagle, i didn't need an entire bare basics session, just a quick run-down from start to finish. For that this is a great tutorial!! Now to start the tedious process of migrating and updating all my libraries. Hard to believe i'm actually making the switch honestly. When i started in 2011: KiCad was a mess and CadSoft Eagle was what i was trained to work with in college. But then CERN got involved with KiCad and Autodesk with Eagle. Now there is a open-source powerhouse while the former champion is slated for deprecation...

if you try again, fix your audio BYE

with this knowledge, I feel I am ready to build My robots ARMY HAHAHAHAHAHAHA!

hi sir, i´m having some issues related to the drazzy's and digistump url's for the arduino board manager, Digistump's website was shut down, or at least that's what I think,do you know what happened to both repositories? and also, do you still have the files for arduino IDE board manager core by any chance? I was thinking if windows 11 is the problem, cause the drivers don't work here. Thank you in advance.

How hard it is to get multiple PCB designs and combine them onto one file? For if multiple people make PCB parts to be combined into a single, larger PCB.

what should i do if i want to use circuit at 650 khz ?

High-quality tutorial! Love to see more

Great small tutorial

Thank you for making this fantastic video. I got my logic analyser working as a result of following your instructions. This now will allow me to diagnose the data on my NMEA 2000 network.

Great !! ⭐⭐⭐⭐⭐

What is the footprint for connector and led?

thanks \o/

hi, great tutorial. I apologize if this is very basic knowledge I'm missing, but why can't we directly connect the MCU's GPIO pin to the gate of the MOSFET? MOSFETs have insulated gates so they won't draw any (or perhaps very little) current, right? much less than the base of a bipolar transistor for sure; so why go through the trouble of connecting a separate NPN for example in the first circuit? Thanks.

Nice video, good explanations. But a comment on the use of "current sink" (BJT with emitter resistor) to drive the boot-strap circuits. The **minimum** voltage achievable at the collector of the level-shifter BC547 (call this Q1) is about 4.5V, due to the output voltage from the Arduino, and the Vce (sat) of Q1. Add to this the Vbe of the pull-down PNP in the buffered boot-strap, means that the mimum voltage at the gate of the MOSFET will be about 5.2V. In most cases this should be sufficiently low to ensure the MOSFET stays OFF, but not always. Is there any particular reason you did not just connect the emitter of Q1 directly to GND, and insert a suitable resistor in series with its collector if current or power dissipation became a concern?

Nice presentation 😅

so ive got my hall sensor triggering my arduino and then arduino into a gate driver chip and then gate driver chip into a mosfet. but the coils are being turned on for wayy to long and its over heating the coils very quickly and not even getitng up to speed, very un smooth, i have a 100 ohms resistor between gate and driver output and10k across gate/source. and a 4k7 ohm reisstor between arduino out and gate driver logic input. can you suggest what im doing wrong here ??

I havent used KidCAD is 10 years, was using Altium and mentor , I need a refresh course form Kicad 8 this video puts me back on track..KiCAD came a long way

ive just bought all the components needed to make your cascode circuit !! i couldnt resist !! to infinity and beyond ! : )

i have another question for you master of mosfets ! now i have my mosfet, 600V CoolMOSª P7 Power Transistor IPA60R08, im not using gate driver yet, but i have my pulse motor that the mosfet is triggering a coil on and off for. the voltage for the gate/source is coming from a trigger coil. the magnets spin passed it and create a voltage etc. And the coil is getting a bit hot, is there a solution to keep my coil COOLER? the coil is significantly hot. the mosfet is a bit warm, but only a little bit, with a small heat sink. but its normally cool when i run the pulse motor at 12 volts. i would like to figure out how to keep things cool at 24 volts. because i get a much better output @ 24 volts input. what i am doing is charging battery's on the output of my motor with the energy pulses that occur when the coil turns ON and off. the transient spikes. do you have any ideas about keeping my motor coil cool in this situation ? its always been a challenge for me. would my coils stay cooler with a higher power rating of mosfet? or is this not how things work ? and do you think the ON time of the mosfet is too long and is perhaps whats causing the excess heat ? the mosfet says 4volts is the max gate voltage, but my trigger coil generates a higher voltage than that, 7 - 17 volts is this naughty to give the mosfet gate a higher voltage than the datasheet says is its maximum? should i be limiting the voltage to the recommended maximum voltage for the gate ? i plan to replace the trigger coil, with a hall sensor and gate driver soon ! thanks for your help so far ! : )

what footprint did you use for battery cell

the cascode circuit: Is the 100nf cap connected to the arduino ground ? and im slightly confused about the 12v arrow, where do i get the 12 volts ? i understand if my source voltage is 24 volts for my main load then i have 24 volts for my mosfet drain/source but im not sure what the 12 volts is ?

You rock the damn house!!! 🙂 I liked, subscribed and really appreciate this super informative video. Thanks!!

If you don't live in a lab it's of any use?

isn‘t the pinout of an USB connector 1-5V, 2-D-, 3-D+ and 4-GND?

Hey thanks for the tutorial, it helped me a lot! However, even though it works, i believe there is a mistake in the schematic. There should be a capacitor between DTR and the RESET pin of the ATTiny (1), thats correct. But then RESET pin should be pulled high. The way you have it, the DTR pin is pulled high and RESET pin is floating, which is wrong. If you check the schematic of arduino UNO for example you see that its designed the way i described. I believe your version works only because of imperfections of the capacitor. The rest of the video is amazing tho and thank you for the tutorial!

it works very well in my simulator as well, however when I built it with real transistors, the speed is very slow. Have you tried it ?

can you make me one please ! : ) i can buy it ! i want to do fast switching without burning my mosfet !! : )

Excellent. Much appreciate the time and effort that went into making this video (and others). Concise, clear and absolutely fascinating - I have a degree in Electrical and Electronic Engineering from UCL in England, but still find this channel to be educational and insightful.

Hi, there, Why did you set "pinMode" to 1 and "digitalWrite" to 1, when the led is connected to 6 ?

Very interesting! I was hoping to see a comparison with the simpler P channel high side switch circuit, particularly since that one can be driven at zero Hz. I'll make that my suggestion for a future video :)

Can the company you order the PCB from do the soldering of components for you?

Exactly what I needed, thanks!!!

Excellent tutorial, Thank you.

Sir can you provide me the footprints you used in every components?? It was fast forwarded when you added the components. I've watched it several times but couldn’t understand. I want to make this PCB. I need your help sir🙏

These are incredibly helpful videos

Great topic for a video! I'll definitely mess around with a few of these drivers. I use PWM and PWM drivers in a lot of my projects

excelente clase y aplicacion del analizador logico, un nuevo suscriptor

just out of curious. what is the memory unit. ATtiny?
