Introducing 3e8blueprint. A tool for turning an Idea into hardware.

2026 side quest unlocked hardware vibecoding

Output tscircuit and you can make PCBs with this!

Nice idea but it went with an approach that wasn't really low power as i asked... And the BOM is pretty high... I literally made a prototype of this with <10 bucks of hw... Let it able to respond more in the chat, interactions cannot rely solely on the section to the right.

So good!!! I was doing all the visualizations + product list by hand with prompting but it does it in one shot

A quick release mounting bracket for a CNC table. really cool that you link to BoM Is this just doing nano banana image gen? No STL or anything?

This is great, I was building something similar literally this morning. My version exclusively uses adafruit's stemmaQT ecosystem to make wiring easier.

it made this:

Made this MVP 220Vac > 20dc 1.5A in one minute

@yacineMTB what's the verdict here big dog

@TowerofAdam1, @RollingHedge and @db_fink this seems like a good way for start-ups to rebuild UK industry.

Very cool... And here's the next step, Vibe-Code the embedded code for the hardware:

I love this

The fun part of hardware is doing your own research, learning through failure, finding new things, techniques, options and solutions. Not to use Ai like a stupid shit to Let Ai do all that and become an factory assembly line worker.

Nice

this is cool. is there a company that can take these an inputs and make prototypes?

@grok does this support the following: McMaster-Carr parts list, sendcutsend price quotes, cad customizations window and recommendations for filament specifics and print settings (enhanced slicer)?

@grok No CAD stuff rn, its for off the shelf electrical components

bless you and your 3am zyn build sessions for this

Ok i tested it , it seems to be sketch friendly and not pcb ready or am i missing something , and it dont give you simple thing , he told me to take an esp32 for a job that a attiny85 can do

Designed for off the shelf components, you can always prompt again to change parts

Ok i'll try to me it prompt the best composent possible to fit perfectly in the project

love these real world building copilots

Mind-blowing. With just two commands, I got steps to build a mini robotic arm. Every detail is 90% perfect. If possible, I'll use it as an assistant for my hobby project. Hardware engineers can also vibe-prototyping. Keep up the good work! 😊

What’s the story behind the name?

@samthecyberguy 3E8 - Speed of Light in [m/s]

clever I like it 👍

Very cool!

this is awesome

Really cool 🤗🔥

this is so cool great job

This is really cool. Makes it easy to see a future where we can vibe code and vibe engineer customer products we want. I want a e-ink smarthome alarm clock for my mother with dementia that's customized to her.

Cooked

This is so good! It needs a bit more tweak but given the time it will get there. Awesome job Good work

Ok this is cool

This is amazing. I've wanted to build this for years. Thank you for beating me to it!

This is awesome.

This is very good. I tested it with a two-sentence description of something i buit this summer and the suggested parts were almost identical. Great for building early prototypes using off the shelf parts. Congratulations!

Very cool

Very cool

This veey cool
