+ Prob a nfc card(nutt)


# Prob a nfc card

Uhm, I'm making a nfc card, What it does is its gonna transfer some info(Byte size) to the supported device via near field communication.

it is gonna cost $38.18(+ shipping)

the challenge of designing this pcb is my laptop is dying mid way and i didnt save :sob: and i have to feed  my cat

16KeyKeyboardPico


I was inspired by my younger brother who got the grant to try a larger scale version of wheat he did. m It will be a 16 key macropad powered by a raspberyy pi pico board using kmk software.

The cost after shipping is: $76.32

# NFS TRANSMITTER CARD FOR FTC TEAM 18221 FOR SHIRT FORMS

I made a custom PCB with a help of a tutorial that will use a NFS chip that will record and send out a link that redirects users to FTC Team 18221 shirt form for the Chicago Robotics Invitational.

$40.34

The tutorial was very helpful, although the part about false positives in the PCB was a little confusing.

1933y-555chaser


# 1933y-555chaser

This board has two sides with different functions. One is a simple LED chaser which utilizes a 555 timer with a variable resistor for adjustable clock. The generated signal is also brought out to a header on the board for other projects, such as driving a simple microprocessor. The second purpose of the board is to demonstrate my learning about computer science through a 6502 based sbc, where I can learn about machine language.

$99.91

My design process for the 555 timer was simple. I followed a prewritten tutorial guiding me through the design and operating principle. I then decided that I could make more of this opportunity than just a simple timer. So, I implemented an OSI 300 compatible 6502 based SBC alongside the simple 555 LED chaser. I had some difficulty in choosing which parts would be preassembled by JLPCB due to component cost, and difficulty in assembling the rest of the board myself. As I am still learning, there are likely some flaws in my board design, but I hope for this to be a good learning experience such that I can improve from my mistakes.

1_PCB_Hacker_Card


# 1_PCB_Hacker_Card

I am making a PCB Hacker Card, my 1st ever PCB Project! Essentially, it is a business card that can transmit a URL and light up when tapped, and is unique to me!

I believe it costs ~$2.00 according to the website, and the shipping cost is ~$17.80 -> Total amounts to: $19.80. 

Created a schematic, converted it to a PCB design, placed components, and customized the card with text and images. The tutorial by Hackclub really guided me in this process, especially since it was my 1st time ever creating a PCB or anything of that sort. Thank you so much, I really had a lot of fun!

2NAC Hub


# The 2NAC Business Hub

Description:\n
USB Hubs are awesome, but as times are changing, we can't really be limited to **only 2 USB-A ports** can we? I added 2 extra USB Type-C Ports in the mix (supporting data transfer as I connected the D+ and D- pins) to the base USB hub, taking full advantage of the microprocessor.
NFCs... are also cool, but just one? I compressed the USB Hub and already existing NFC tag to add ANOTHER NFC tag!
And finally, the board also contains buttons, some doing nothing while some light up a wonderful data tree, for times when you need a simple fidget toy (battery needed).
Perfect for promoting yourself to employers, being an actual useful PCB, and having a bit of a stress reliever, all in one.
2NAC: 2 NFCs, 2 USB-As, 2 Type-Cs. In a Hub!

Cost:
Costs $93.51 for the total package in JLCPCB.
- $77.71 Total PCBs (and some assembly) cost
- $15.80 shipping costs

Design Process:
- I took inspiration from the USB Hub but found it lacking, so I took advantage of the remaining 2 slots to add Type C ports (since my laptop only had one) with data transfer support.
- As for the NFCs, funny enough other than vehicle RFIDs, I never ever touched an NFC tag ever in my life yet, much more interact with it. So, I found just one tag lacking and wanted one more!
- For the extra lighting and buttons, to be honest I wanted more fun features like LEDs on plug or Linux on board or a 2FA key like yubikeys, but lacked budget, knowhow, and most of all, space. Thus, I settled with simple fidget stuff!
- Design wise, I wanted it to be actually interesting and show me for me, instead of just being a boring "wow okay PCB business card", so I attached drawings at the back and a QR code that leads to a wonderful YT video (rickroll)

Challenges? Excluding budget, I lack know-how. I really want to learn more PCBs now since they can REALLY do a lot. I found so many interesting projects in the project folder I WANTED to give a shot at but lacked experience.

Maybe someday I too will have Linux on a Card!

2_Switch_Keyboard


# 2 Switch Keyboard

## Summary

I am trying to make a 2 switch keyboard, that can be used as a macropad, as a switch tester, or just a fidget tool.

## Plan

I plan to order the 5 pcbs from JLCPCB, which quotes them at a total of 2 dollars. 
I then plan to purchase some promicros with headers, and each one costs around 12 dollars.
I'll also need some mill max headers, which will be around 5 dollars. 
So, adding in costs for switches, assembly, and shipping, total cost might be around 80 dollars ish. 

## Design

I was inspired after seeing the 2% milk keyboard, and used it as the basis of my design. I then followed Maggie's tutorial and this [tutorial](https://www.youtube.com/watch?v=ajjujZ0f_sk) from Datulab Tech on how to make a pcb!
