Hi,

I am Vishal Soni , checkout my youtube channel for more videos.

I made a digital business card, it is like remote control in your pocket, it can automatically open all of your website and write all your business details on notepad.

Why i made this :-

In this digital era people are still using old business card or visiting card to introduce there business. So i was thinking to make a advance card which can show all of the card information in PC. The process i have used is very simple and easy to customize.

But why squid games business card :-

Actually, squid games is a famous web series, and the card used in that series was unique and well designed. Ao i used a reference of that series to make this card, i have shared the PCB design of the card so this is also very customizable according to requirements.

This is a PCB based Digital Business Card, it has USB interface to easily plug in and plug out. The card is based on theme of famous web series, which is Squid Games.

There is no need to connect battery or any cell to this device, it will take power itself from USB. This easy to carry business card can contain all of your details in your hand. The card can be customized with little bit of code knowledge.

Let's build it.

• Digispark Board
• Squid Games Digital Business Card PCB
• oldering iron

Firstly we will take Digispark Board, it has built in usb driver so it can be directly program with PC.

Because this has usb driver we can perform HID with it.

HID (HUMAN INTERFACE DEVICE) :-

The Human Interface Device Class (HID) is mainly used for devices that allow human control over a PC for an example, keyboard and mouse is human interface device, so human can write and click inside the pc.

Secret:- people also use as rubber ducky.

By using this HID feature, i made a digital business card PCB, the PCB looking beautiful because it has same look as the business card in famous web series.

The PCB for This project is sent by PCBWay, checkout there website to order PCBs.

If you are programming Digispark board first time then you have to install the board in Arduino IDE.

Download the folder from my GitHub page from link given below.

GitHub :- https://github.com/vishalsoniindia/Digital_Busine...

Extract the folder, in the folder there is a text file.

Open the text file and copy the link given in the text file or also the link is given below.

Digispark Board link :- http://digistump.com/package_digistump_index.json

Copy the link and open Arduino IDE.

In Arduino IDE go to the files and then preferences.

Paste the link in additional board option, if there is other link then separate it by comma.

Click on ok, Now go to the Tools >> boards >> board manager, here type Digispark and install the board.

• Find the code in the same folder which is download from GitHub.
• Open the code and select board as Digispark 16.5Mhz.
• Click on upload.
• When you see connect your board below then connect Digispark board with PC.
• After a sec you will see the code is uploaded successfully.

Customisation of code is very simple, just replace the website to your website, and text of note pad with your text. If you comment the line, it will no long exicute in code.

Firstly i made a schematic in kicad, and routed the pcb.

Every pcb trace and components routed in such a way so it looks good on pcb.

After routing i have made some designs using silkscreen, solder mask, and copper finish.

The theme of the card is squid games so i made it same as card used in series.

After designing the pcb i uploaded the Gerber on PCBWay.

The thickness of pcb is 2.4mm, so it is perfect for usb slot. Also i selected gold finish which looks cool.

Afer arriving pcb,

I have transferred all the components from Digispark board to th pcb.

I have recorded a stop motion of transferring components, but this is not what it looks like.

I have de-soldered all the components with soldering iron, it will be easy if you use a hot air rework station.

Then i soldered all components to our main pcb.

Wooo laaaa !!!!!

It's done now just put it in your PC and see the magic.

It will write all of your information and open all the website.

If this will not work go through all the steps again to check if anything is wrong.

Bonus:- you can still program it 😉, becouse the data bus are still connected with pc.
