What do you recommend if wireless is not necessary

What are your recommendations if wireless connectivity is not necessary?

Thank you :)

I made my first PCB my junior year in college. I remember uploading the files and asking my professor when the feeling of panic and apprehension would go away. He told me I would start feeling better after I had done 20+ boards. I had done 10+ by the time I graduated and who knows how many since that first one in 2006. By now I'm confident that feeling will never go away.

Does ESP 32 come with certification for FCC DOC and Europe/CISPR intentional emitters

My Atomstack X20 Pro Laser engraver/cutter has a ESP32-WROOM-32U as the heart of it's motherboard.

Altium is terrible and way overpriced. Plus they will borderline harras you to buy it if you get the trial. I suggest eadyeda it's easy to use and has a massive component library ready to go.

This is so helpful! Thank you

With sls tech you don't need mold

I use ESYEDA to design my PCBs

Probably you never used PADS from Mentor

I just threw my prototype in the bin after watching this.

Fantastic overview, thank you!

Another fantastic video! Thank you for continually providing invaluable insights. Your content is a game-changer.

Are you the kid from the Mr Bean vacation video or related to him? You look so similar, and the timing is about right XD I am really glad I found your channel, enjoying it very much. Thank you

Great information Thank You.

🤩 Illuminating!

Hey Sir, I’ve been watching your videos across the board: electronics to injection molding. After watching your injection molding videos, I’m still unsure how to design parts that take the injection molding into account first. Is it possible to design injection molds with Fusion 360? It would be cool if you made a video that applies injection molding concepts using Fusion 360 or some other free CAD software.

The 'ignoring my wife' part yaayyyy that is what i call a risky business

When I started making PCB's in the mid 70's, I used everything from fingernail polish to tape on mylar sheet. Things have certainly come a long way. Like programming, it's become so easy and so cheap that every 9 year-old can do it. Almost takes the fun out of it, but not quite. 😄

Is there an MCU available today, even a very basic 8 bit one, that does not require an expensive hardware component (programmer) or a specific required IDE in order to program it? I have quite a few 12 to 24 VDC contraptions that I would like to develop, and have already started on the first. While MCU isnt strictly necessary in every application I have in mind, they could be helpful. In my case, arduino et al, as great as they are, would be overkill, with the vast majority of features unused. I want a MCU that I can program without expensive specialized hardware using code that I supply to it in Assembly or C written in any text editor I choose. Does such a thing exist? For now I am making my first version of my first project, and also going through the Mimms Radioshack learning lab circuits ... I realized at an early point that I needed to understand more about circuits than just wiring and programming a programmable IC. A lot of what I need can be done with non programmable ICs, like 555 or op amps. Enjoyed the video, new sub. Thanks for sharing, please be encouraged to keep sharing with us!

I love Arduino, mainly because how easy is to start with, the boards are usually well done. Now I'm trying to design own boards, Arduino and shields are good source of referece designs, such as power supply, mcu connections, antenna design, ,..

I've used eagles for a while Till one time i checked my designs And to my surprise I've found that i lost all my designs hours of works Because of a silly bug in this shitty software

Most have SPI and I2C controllers, but to execute program in such memory you must copy it in internal RAM and set that as executable. So that is a hassle and slows down execution, but you can store lots of data in I2C or SPI memories

YESSS. THANK YOU. My university makes us use Eagle for our courses but on the student design teams we use altium (it’s free for us since we are students) and eagle is SO BAD. It’s like nails on a chalkboard

This is what I need at this moment, thank you.

It's really helpful to hear real life stories, I'm so interested to contact you for further communications.

😂😂😂 very similar experiences

Designing - producing - selling in highly competitive markets. No piece of cake. Specially when you are a newcomer. You have to have a promising IDEA and you have to have BALLS. Entrepreneurs are inspiring.

Wow - a 6 unit test at an Ace Hardware is awesome. That's such a great testing ground

stm32f103 is the best because it is used in st-link, china price 1$

Phew! My boards don't have these errors. Thanks for the handy quick reference list :)

This is all great info, I am going through this process right now. I spent the last 7 years working for a startup until i left to start my own company. I know my product and market very well.

Was using kicad but notice jobs in my field all want altium including the work I currently has, luckily work pays for the license I might as well learn it

Hello John I appreciate your work on the Hardware Academy platform, but my observation is that the subscription prices on your platform are very high, which does not allow beginners or students to learn. Personally, I am a new graduate. I am trying to enter this field and learn from experienced people like you, but I cannot pay a large sum of money for this platform even though I love its content. This number is approximately equivalent to my income for more than two months in Africa. I hope that subscription prices will be reduced

yeah, but for that temp humidity example ESP 32 might actually be perfect because of the ULP capabiity and deep sleep features, plus wifi bluetooth and there are just bucketloads of them around

Hello! Great video. How would I modify this schematic to include the option of powering this setup using EITHER the usb source OR a battery, making it able to be entirely wireless?

Hey John, how did you approach and convinced him to invest in your project ?

What is considered high speed frequencies? Is there a rule of thumb when to seriously consider delay lines (kHz, Mhz, GHz)? Or do you have to calculate it yourself every time?

Do you did made some IP protection before contacting these companies or in general? Thanks!

Well already happened but no network access for this thing. You still have to certify and let you module be checked. Well the RF design is trivial for a real manufacturer that creates mass products.

I agree EAGLE was the worst user interface ever presented in a Windows environment. They reinvented what is a computer mouse and before interacting with an object you had to tell what to do. Especially MOVE was crazy where one click would stick the object to the pointer and the next click would unstick it. Also KiCAD is near crazy but not the user interface. Where EAGLE actually does a decent job. Associating a symbol with a footprint and then with a 3D appearance takes forever. There is an enormous lack of overview when libraries are loaded and inspected. The things it produces is ok, but working with components could have been arranged in one page. Sometimes you have to know you should DoubleClick an item because a right click does not offer the open function. The application is full of closed doors where you have to take another path.

hey, do teardown on Rabbit R1.

The way I see it is, if you're a hobbyist making ESP32 boards with bad routing techniques, use KiCad which is quite decent. If you're a professional then use Altium Designer for complexil multilayer stackup impedance controlled high speed designs.

Any thoughts on Allegro/orCAD?

LibrePCB is another FREE and open source you might want to give it a try!

When this started I immediately went "Kicad does everything I need" it's a little unintuitive at times, but for 99% of projects it does the trick.

Thanks Jon. Highly appreciated ❤

Thank you so much. Im doing my bachelor thesis and i have to do pcb design a lot. These Tipps are fantastic and explained efficiently and clearly!

Wi-fi feature can be disabled, if not needed. On the other hand, #1 strength of ESP based modules is offering 4MB+ eprom.
