Hello sir, I have a interest in learning pcb design which is like backbone of electronics. Can you please recommend some online course which can help me learning pcb design and electronics.
I am trying to design something with a chip antenna as well, I am a bit lost on how to make sure it works. How did you devide the impedence matching network setup and values used?
hi. Can I ask you a question: Can this display completely lay down on the PCB? It seems like in the video that the display cannot, is that because of the footprint position or the display itself? This is a very good video, I'm planning to make a mini weather station after watching your videos haha.
Hello ! Great development. I would like to try my hand at this development. Can you change the link for this homemade product (Gerber, sketch, radio components diagram...) otherwise the link is dead? Thank you in advance !
how safe is it to use lipo batteries in self-made electronics? Do you have to worry that when you abandon the project somewhere in your closet it could become a fire hazard?
I got some of these modules and I was surprised to see how much current they draw. I went to RU-vid to see if anyone had figured out how to make this portable and battery powered, and after watching your video, it seems the answer is - no! Those current draw tests at the end reveal that with that little half-18650 you could expect maybe 24 hours of battery life if you only record GPS to SD and never transmit over GSM. Maybe 6 hours of battery life if you start using the GSM.
Every time i watch your videos , i get an idea, and your projects are awesome I was wondering where you buy these sensores . Some people sayed you can buy your components from digikey . Digikey is overpriced. I wanted to know where can i buy devices like you Thank you.
I'd like to build the tiny version with a width of about 10mm. The height doesnt really matter and I want to try to build a version with more useable gpio pins. Basically a seeed esp32 just longer so that it has that desired width. How do I do that? Can I just download the original seeed esp32 files anywhere and then make my own pcb and then just use all the components from the seeed esp32 pcb and transfer them to the new one?
Want to track my cat in the house. Instead of attaching one of these to the cat, attach it to the door frame of every door in the house. It needs to support RFID. The cat would carry an RFID tag on its collar and when it enters a room, the LORA tracker on the door frame picks up the RFID tag info and transmits it over WiFi to a computer, web server or mobile device. While it won't tell you where in the room the cat is located, you can at least known which room the cat is located in.
Hello! I am designing a PCB very similar to the one you have designed in your GPS tracker project. I would like to know how you have designed the power circuit. How do you stabilize the voltage at 3.3v when the battery voltage drops below that value? And what voltage does it power the Ai-Thinker A7? Thank you so much!
PLEASE DO NOT IGNORE IF YOU ARE READING THIS..... Moritz i.e makermoekoe I am a student and I want to build the three wheeled version myself but to be honest the video is great but the building tutorial is not the best..... also there is no link for the gerber file for ordering the pcb from pcbway and no list of used electronic components either..... and also the code is not given either.... thus this makes it impossible for someone like me to recreate your project...... You have no Idea how much it will help me if you made a new video on how to properly make the three wheeled robot-car with all the necessary links, components list , code and a perfect tutorial...... please like this comment so it goes on top and hopefully he reads it.......
That chip antenna design seems crazy to me. As a relatively new hobbyist Ive been told over and over that rf is difficult and that you absolutely needed a pi filter and to play with the values. How did you get this to work? Have I been mislead? Does this get good wifi reception without high effort simulation or vna testing?
And the above, broke the law! On internet - public G-- mandatory gay + dopamine! 2. No personal venue allowed - with other - another's product! Tax payer
