Applying GND or VCC plane should be done in a calculated manner. Take this example I have from my experience. If you have a small BGA chip (2x2mm), that doesn't require a lot of current. CAD program will rout the traces thin. BUT!!!!! The GND plane will be thick. The trace of GND will be much much thicker than all other traces. What is bad with this? Manufacturer of the board will face a difficult time to balance the oven since for one pin you need a lot of heat, and other doesn't require so much. Which results in either total melting of the balls of the other pins and shorting them, or if the temperature is not enough to melt the GND pin's ball. It will result in cold-soldring. You need to be careful .. Applying big GND or VCC should be with thoughts.
Great video! Although, when doing it with your finger while grounded, you should use the same hand that's grounded, this will prevent charges going through your body past your heart. At these low currents it doesn't matter much, but just a good safety precaution
I loved the sound of the whole display changing when these updated. So disappointed when the display got "updated" to big LEDs in Edinburgh Waverley. EDITed for clarity.
Awesome. I remember huge panels of these at British railways stations in London like Waterloo when I was a kid in the 70s and 80s. You can't beat the sound of 24 platforms of split flap signs all updating in a wave from left to right. Such a cool technology I'd love to have a crack at building one..... Thanks so much
Thank you so much for this ❤. I have a question....I was being told that ALTIUM is the most used PCB design software in the industry right now. As a first year electronics Engineering student I am really trying my best to learn everything although it's not even being discussed in our University. Is ALTIUM really that needy? What should I do to be ahead in the electronics Industry? Plz answer ❤
Brother can we train siren and recognize using this code if not how to achieve it pls do reply its really urgent :) hope you see this comment and reply :)
Thank you so much, you can also make a lightning colorful cotton cloud project which can be small for hanging below the house roof or installing it throughly below it for make girlfriend or wife happy👍🏻 it will has very good feedbacks, also you can control its visual effects via Bluetooth from android phone. The usual best board for this project is ESP32 and the LED strips which each LED can be programmable is from Neopixel brand, and if you choose its denser strip types and lastest version of it you have more resolution and better colorful effects, which can glow behind the cottons like rainy and lightning clouds in the sky!

my place button (in manufacturer part search) not active. Can you help me?
While updating pcb, it is showing as comparing schematic document and pcb document no difference is detected and there is no Pcb updation, why is it so ? Please tell what’s wrong?
My raspberry pi is not recording my voice i connected the mic using USB sound card all are recognised by raspberry pi but not working I have tried lots of ways like resetting the alsa mixer but it didn't work iam using raspberry pi 3 B+.... the mic and sound card are working perfectly in the pc
I would say one example how you would need to do so. If you want to sort the components you are using by the functional area, you wouldn't let the placements sequence decide the components number. You would like to decide the components number by yourself. That will help manufacturer of your board or yourself when you do rework, or mounting works. I had many time at the job so difficult time to find component where you wanted to find for example after R22, finding R23 which should and supposed to be near to the same area, while I founded R23 at a location which was far away from the R22. That make your life too difficult.
Question, do you also set the grid to 1mm on the Schematic page? (and does it matter if you set the grid before or after you have made your schematic?)
I don't remember about the schematic, but I think that the grid was set on 1 mm in schematic page. And it does not matter if you set the grud before or after, it only changes at what intervals your mouse is locking to points. For myself I always try to use smaller grids like 1 or 2 mm.
