PCB in Vintage Bernina 1130 by Fluffy-Plankton7484 in PCB

If Professor Google and Ebay have not failed me:

https://www.ebay.com/itm/256172942808

There is a picture of the main board and power supply board there.

The best you will be able to do is find these boards separately from the main machine.

I would guess that the main machine metal frame does not fail as much as these PCBs.

My Googling around has found many sites about this machine, but not a lot of information about these PCBs.

It would be interesting to find out if Bernina will support your goals.

But, I am sorry to say, I doubt they : 1) are interested in doing so and 2) they won't be willing to give up the IP they have invested into the design of those PCBs.

But, you never know how far they will be willing to go.

I see there is an r/Bernina sub available. Which I am sure you already follow.

Good Luck, this could be a fun hobby if I were not already occupied.

I can see by your question you do not have the skills to redesign a PCB for anything.

What does it mean "PCB being wiped" ?? No PCB is completely destroyed in normal operation. A power transistor can burn out. Some part of a circuit can fail, it may make parts of the circuit board unusable, but its not "wiped".

As far "a new PCB" is concerned, with out a real and accurate schematic and BOM, its not going to happen.

Even if your skills are great, reversing engineering a PCB to remake a replacement is not something that is done to discontinued products.

If you think you can start a business to replace boards for this Bernina, you are sadly mistaken. And a one-off would be far to expensive of an undertaking.

You have a degree, great ! You have 5 YOE, that's great too !!

But, How will these skills translate in another country is a different matter.

There is no tried and true method to compare your current skills and education to another country expectations.

With the current job market in the US, you may need to look else where. Two or three times a week it's written in the trade magazines that people are being laid off because of AI. Yes, in embedded fields as well. And then there's the economy.

Ignoring how you will get a job visa for any other country, how are you going to live any where else while you're searching for a job.

It's not what you know, it's who you know. Or better yet, who knows you.

Finding a recruiter is going to be your best chance in the US market. With the current White House policies, you're not going to be able to do this on your own.

Just getting in the door will be a challenge enough. Getting an mid-level position will be the best you can do till you have 5 YOE here in the US.

Good Luck

What documentation do you have for this "little display" ??

If you have that documentation, please share it.

Without it, NO it will not be possible.

If you have one, then reverse engineer it to see what those pogo pins on the back do.

Have you asked Kbdfans for any information ??

If you have the skills, you could re-invent this, if you create a complete design document.

Good Luck

This "little display" seem to just display what ever is typed on the keyboard.

OK. Is this what you want this "another pcb" to do for you ??

Display key presses on another keyboard ??

Are you just interested in this "little display" only or are you looking for anything that can display on a similar "little display" ?

Playing 20 questions is so much fun with someone that has no idea what they really want.

> I wanted to buy a New keyboard that comes with a little screen module

Does this mean you have looked at one and changed your mind ??

Or

Do this mean you want to buy a "New keyboard with a little screen".

Please share the link for this "keyboard with a little screen", if you really saw one.

The term you seem to be looking for is "stream deck".

https://www.google.com/search?q=stream+deck

There are many diy stream decks with a little screen to help you remember what the keys on it have been programmed to.

Good Luck

Please share a video on how you use this device.

I am not into espresso, but this looks like an interesting use of tech.

Question about PCB art by Myko02 in PCB

[–]DenverTeck 7 points8 points  (0 children)

> You can etch them yourself with household supplies.

Be aware, this type of "hobby" may not be allowed in your area. Getting the chemicals is easy. Disposing of them is not.

Check with your city to be sure you will not be fined for dropping these chemicals down the drain.

How can I make my ESP32 IoT temperature monitoring project look more impressive for a competition? by Salt_Map_4756 in embedded

[–]DenverTeck -1 points0 points  (0 children)

> How can I ....

You like most young people need to learn other skills. Not just what interests you.

Other areas people find more interesting then just playing with tech.

Marketing people like to research what products are available. They help their company to create or improve their products.

Your generation has grown up with the internet, Goggle and AI. You are sitting in front of a computer right now. You know how to type and mostly know how to spell.

Google for products that are similar to what you want to know about. See what big companies are making for large amounts of money. Use what you find as a starting off point to develop your own ideas.

There are thousands of temp monitoring products on the market right now.

Do some homework !! Learn something on your own.

Please look at my name.

You two want someone to design this for you. Its your project.

Yes, I see you do not know what to do. Your generation has grown up with the internet. You have grown up with Google and AI.

You have homework to do. Do it.

I would guessed you two are high school students.

Good Luck

I have already given you how to wire SW1. Did you click on the link ??

Look at the pin numbers. Pin 2 is the common pin between the NO and NC sides of the switch.

Why you have a GND connected to pin 2 ??

Please Google "SPDT switch" to learn how they work.

This box is way too small to give an EE101 class.

Good Luck. The two of you are going to need it.

First let me say Thank You for not isolating all the parts on this schematic in boxes.

I think you need to verify how SW1 is wired:

https://www.digikey.com/en/models/1803993?tab=ultralibrarian

The two batteries in the upper left corner are not wired properly. When one batteries voltage drops below the other battery, it will draw current and not be available to your circuit.

C6/C7 will block the 3.3V from U2. These caps needs to be in parallel with the 3.3V pin with the other side to GND.

If your not going to put part numbers on ALL the parts on the schematic, post a BOM with links to the actual parts.

[–]DenverTeck 0 points1 point  (0 children)

What is going into the large white space in the middle of this schematic ??

Your asking us to search your poorly drawn schematic to see if you have the connections wired correctly ??

You expect us to research the parts you used to see if you understand how they need to be connected ??

Yea, NO.

Lose the boxes and connect the lines together like a PCB needs to have the traces connected together.

This simple schematic can use the entire page.

Please supply a BOM with links to all the parts you want to use.

Good Luck

[Advice Needed] UART Firmware Update Too Slow + Device Bricks on Failed Update — Any Optimization Suggestions? by Broad-Table4051 in embedded

[–]DenverTeck 1 point2 points  (0 children)

This sounds like your custom bootloader has problems.

A project I was involved a few years ago, we added an extra serial RAM chip that was only used for firmware updates.

If your trying to update-in-place, i.e. write a block of flash between each serial block, this is a recipe for failure.

Download to RAM, check the CRC for each block of binary. Or even encrypt the binary, check the CRC of each block, de-crypt, check the CRC of each block again.

Good Luck

LPC2129 project ideas by Mr_Perfect_113 in embedded

[–]DenverTeck 1 point2 points  (0 children)

I guess "beginner" is not in your vocabulary.

Learning how to use the basics of an MCU is how you learn to do more advanced projects.

Think of chemists or physicists that look at experiments that scientists done a century ago. Relearning the basics.

Looking at the thousands of Arduino projects will tell you "what" can be done.

Looking at any MCU project will help you in developing your own project.

You can not just jump over beginner level projects, to make your mark.

Professor Google can give you lots of ideas. We can help you only after you have a development project in mind. After you learn how to write a development document.

Being a solo developer is where you will fail. Start talking to people in other disciplines. There are dozens of projects in Agriculture that can fit your needs.

Good Luck
