This is a design overview video which I made for Part Two of Learning the Art of Electronics (which was all about transistors). It is a circuit that uses a photoresistor and transistors (made into a voltage comparator) to turn an LED on if it is 'dark' and off if it is 'light'. Honestly it is the most technically complex circuit I have made so hopefully it turns out well.
This circuit was based on a circuit found on page 124 of Art of Electronics.

thank you sir for sharing your knowledge
Hey great vid. I reckon adding copper pours and thicker traces to minimise resistance.
Thank you. That is exactly what I was thinking. At least adding a ground plane. The next iteration will happen later in December because that is when I will be going through the Voltage Regulator chapter of learning the art of electronics. I'm trying to design with only the stuff I've read in that book just to help solidify the knowledge in my head. If you have any other suggestions please give them I am looking to learn!
Thank you for sharing your knowledge
Thank you for watching! I hope you got something from it
No annoying intro, no annoying music. I'm using KiCAD 8 and still solid!!! Well done.
Cool.
the result of the doping material to create the LED colour. good to know when creating a battery powered project.
Thank you! I always knew that their was different voltage drops but never connected it to the doping material
nice!
Thanks!
A concise video that actually answers the question is a rare, refreshing find. Thank you sir.
Glad it was helpful!
you fixed my issue
Awesome!
THANK YOU😃
just found your videos, Liked and Subscribed, Thank-you for your time and effort.
Amazing!
KiCad 8. Right mouse click on rectangle -> Shape modification.
Cool. Thank you for sharing
Bro tell us how to decide width before start please!!!!
Sorry. For this video I just want to show how to change it. There are many guidelines and stuff out there. One day I may do some videos on it.
Thank you Kody, super helpful even in KiCad 8. Cheers!
check shape modification when you right click on rectangle.
Thanks
It was so helpfull thank you Mr. Kody Rogers
Thanks!
No problem!
Add from where to where?
This video shows how to add a library of symbols (assuming you've downloaded one from somewhere) into KiCad so that you can use it in your schematics.
What is the name of this device?
I called it simply the annoying buzzer. It was a project I made to learn more about 555 timers. I did have some for sale at one point but do not now (maybe in the future?) There is something similar called the annoyatron.
@@enbyhackeror the Annoying PCB
thank Kody
Thank you!
Perfect video! Less than 1 minute to explain something. Thanks!
Glad it helped!
@LeanderSeige I'm thinking of doing this series again for the latest KiCAD and doing a similar series for FreeCAD. Would that be interesting to you?
Nice video ,thanks :)
Thank you I am glad you liked it. It is fun learning how to use the different tools involved
In 46 seconds my question was answered, many, many thanks ;)
Thank you!
I know this video is over two years old, but here's my two cents regarding this design: The video itself: 1. The microphone is echoing and low quality, not saying you need a super expensive mic but a blue Yeti for $80 might be worth investing in or something that can fit your budget. The same can be said for your face camera. 2. There's no thumbnail, I'd recommend looking at ones online where you can make them for free, Canva is a good example 3. Longer videos like this are fine. However, try putting more time codes for the schematic section and how long you're working on each part, rather than just having the PCB section and ordering it. 4. If the video doesn't show all the screens you are working on, it's worth re-recording. Though it's a hassle people want to actually see what you're working on rather than you just talking and claiming you're searching for a part, if you record bite-size clips (2-4 min) for each section then re-recording becomes way easier. Schematic: 1. GND and Power Symbols are sideways, always keep them facing vertically. You also don't need to show "GND" on your GND symbol as you only use one GND plane on this board. 2. Connector symbol text needs to be flipped vertically, though it's still easy to read it can look messy when placed horizontally like the way you have it. 3. You said that you put a zener diode for your pressure sensor to protect the MCU as it can only handle up to 3.3V. Why not use a resistor voltage divider instead like you did for the other resistor and thermistor? It'd be cheaper than using a diode, and while it would increase power consumption would be higher for this project it wouldn't be a big deal. 4. How important is temperature accuracy for you? If it is, a sensor that can be controlled via I2C or SPI would work a lot better than a thermistor and a resistor in series. 5. References for symbols should never be placed sideways, the same comment as GND and Power Symbols mentioned previously. 6. You put your PWR flags separate from the shield when it should be tied directly. Although this is not an electrical error, it's rather confusing for someone trying to read and understand your schematic. 7. Parts are missing their vendor part number and price, also wouldn't hurt if you put their respective datasheets as well. 8. Net labels are missing on each connection from the pressure and temperature sensor to the Arduino shield. 9. More of a preference but try and stick to surface mount components for the resistors and diodes, you'll be able to fit a lot more on your board without actually having to expand the size. PCB: 1. Reference designators for parts are horizontal, again keep them all vertical if you can there's plenty of space on your board to do so. 2. All 3D models are missing for your components. 3. Why does only half the board have a GND plane? You said something about not wanting to interfere with power traces but a board like this could really use a two-layer stack-up with the front and back copper as GND. This won't create any shorts as you're GND plane will fill around each power trace you make, and so long as stitching vias are present and the entire board is covered you won't have any problems. 4. The pressure sensor and Arduino shield are missing proper labels, I would put them near the connector if possible. 5. More of a nitpick but rounding the corners on the board itself is more aesthetically pleasing. If you have any other questions I'd be happy to help anytime.
Hey! Thank you so much for your input. I will definitely be looking it over!
Hi. Again sorry for my delayed reply. I wanted to sit down and go through all your suggestions when I had time to do it properly. 1. That was a serious issue at the start. I have a nexiogo camera that appears to help, and I have made better use of OBS studio filters. I probably should spend more money on this issue, but I tend to spend my money on more electronics and other tools. 2. I do try and make some with Gimp and I have definitely noticed that the click rate is much higher. I am not sure why I didn't make one for this video, and I think I'll make one for it and it later. 3. I definitely should put more time codes in for a long video like this. Thank you for pointing that out. 4. This is also a great suggestion. I think that in a hurry to get things finished (I tend to pile projects on top of projects and it slows everything down), but next time I make a longer video I'll take your advice. I will respond to the rest of your suggestions soon. Thank you again for taking the time to watch the video and write such a detailed response!
I'll now respond to the schematic part. 1, 5. I had this comment before on a board that I made for work. I made the first version of the board and then insisted to get a review of it, and they commented on the same thing. For the comment on not needing to use the 'GND' symbol I think I would still prefer it because I think it makes it clearer. 2. I will keep that in mind. 3. I don't really have a good reason for using the zener other than I think I had it in the shop at the time and decided to use it. Thinking about it more now a voltage divider would probably be a better choice. 4. For this particular application it was not very important and really I was just trying stuff out and was just learning about how to read themistors. 6. This time I was actually following someone else and how they did things. For the most part I do agree with you about it being potentially confusing. 7. I have always meant to do this and really just need to be more disciplined and try not to jump to the PCB part so quickly. 8. Yah this would probably tie into my response for 7 with my eagerness to jump to the PCB and finish the project. A few steps tend to get skipped by me at the moment because I am not disciplined enough to complete it all. 9. When I made this board I had not yet even soldered surface mounted devices, so I intentially avoided them. I have used them now and would think about things differently.
Now it is time for the PCB replies 1. I think I just left them however the footprint had them. Do you know if there is like a checklist somewhere where all the directional conventions like this is listed. 2. Yah. I never have bothered to add 3D models if they were not there initially. Is it good/common practice to do so? 3. This more goes to me not quite having the best intuitive sense of what is good when designing a board. Currently I am making an effort to 'get back to basics' by reading/going through the Learning the Art of Electronics. I am doing all the labs and then at the end I do a small project and make a video about it. I am hoping this effort will get me more experience designing and henceforth make me a better designer. 4. That was definitely an oversight. Thank you for pointing it out! 5. I also agree with that and since this is an earlier PCB I made I probably did not know that it was a good idea to do that yet. Again thank you for checking out my video and giving me such great feedback. Since this video I have gotten better, but still have alot of bad habits and not much experience (my day job does not involve much electronics). I will be incorporating or at least referencing your recommendations in my next PCBs.
@@enbyhacker What’s your email? Maybe we can do a google meets call sometime.
When I click s, nothing happens, is there another way/shortcut to set the origin?
Hi. Sorry I was not able to help you. I'll try and find out why it was not working.

Hi. I'm sorry are you correcting my grammar or was that a question?
great !! but audio sucks ...
Yah. I know. Still fiddling with OBS and stuff. Cheers
thank you, you are a friend
Thank you!

Hi, jean-yves from france. Thank but when you have many, it should be good to automate that.
Yes, you are right
The video quality of your tutorials is very poor; they are almost illegible.
Thanks for your feedback
How this is not working for me? I'm using KiCad 8.
Hey. Sorry for replying late. I have not actually used KiCad 8 so I can't help you unfortunately
@@enbyhacker No worries, problem is solved and I've already received my JLCPCB-order :)
Usually you put drilling holes into your schematics. It's like a component you place on the board. Search for mounting hole in your library.
@@samael5782 Yeah I figured it out and I have the PCB in my hands already :)
thank you!
You're welcome!
