Price changes

I got the price on jlc PCB down 12 bucks

Plus in the AliExpress cart try looking at the subtotal area on the right and you'll see 20 bucks in taxes. The original price was 20 bucks on my items. This isn't my fault that my country has high import costs

Nice project but it's still too expensive! I can't see the entirety of your aliexpress cart so I'm not too sure why it comes to $46, but try to bring that down a BUNCH, maybe try getting it from somewhere else. Please re-submit when you can get your project below $50, and if you need any help, feel free to reach out in #blueprint!

Reviewer Notes

hello again.
the price is high because of import taxes (excluding customs)
i had talked about this with a HQ member and they said that they would take it up with the rewiers:

PCBA was more expensive as in my previous cart screenshots ($120)
while soldering myself saved me around 20 bucks

here is the components cart:

heres the pcb cart:

Wdym you can't see the full cart it's literally the full cart screenshot

Cute project :D It's got a bit of a price problem though, you're buying way too many components, from a really expensive place which is making your board really expensive. I'd suggest finding a cheaper place like LCSC to get your part at, or even getting PCBA for your board would be cheaper. Your shipping costs are also really high, could you please provide a screenshot that includes all of your shipping costs! Your entire project should be under $50 because as it currently stands, your board is a tier 4! It looks good so far, just needs some major price changes ;)

Your cart screenshots only show as $5 (one single screenshot), you don't have your PCB in your BOM or cart screenshots!
Since your cart screenshots don't add to the requested ($99) amount, I will have to reject it :(

hi! Like nimit said, this bom is quite expensive, please listen to reviewer feedback and take action based on it.

NOTE FOR REVIEWERS

I didn't add YouTube demo link because yk it's just a design.

I am submitting for tickets now as ordering the components from online will be a compilacyed process, especially multiple and components which get expensive after taxes

Nice work, but your BOM is too expensive! For this project, I'd suggest using larger footprints and sticking to standard PCBA components on JLC. Alternatively, you can solder them yourselves, as the components on this aren't too small

"https://blueprint.hackclub.com/admin/design_reviews/N/A" Your demo link goes to that link which returns 404 not found. Additionally you are not asking for funding? Does this mean you already bought the pcb and don't need funding? If not attach the pcb cost in cart and request funding!

Final finishes

I forgot to set an edge for the board, so i set it up so the PCB can look like a real sneaky PCB 😝😝

Done routing the PCB

Finally done with the routing. It's literally so simple but still it was difficult to routem I wish kicad had an AI router 🙏😭.

AI should be smart enough for routing.

ContinentalDrip added to the journal 12/4/2025 at 8:57 PM ago

Started Routing

I started routing the PCB. Idk why but every PCB I try to route, it's just too damn difficult. Hats off to the engineers who design these PCBs.

Drew the Schematic

I drew the Schematic for the atmel tiny 85 MCU. I tried to copy the attiny 85 due to its form factor and small size.

Here's the schematic for the complete board:

I designed a custom footprint for the PCB USB connector.
