Claude Opus 5.5 just made a completely new PCB for PCBA with JLCPCB. STM microcontroller, usb-c, i2c and power. This summarises the steps taken to make it. Let me know if you want me to provide a longer video with more details.

Since I had existing CAD images to start with, I decided to test Claude Opus 5.5 against Grok 4.7 (xhigh) for animation creation. They started with the same images, hence they look similar but I do like the Opus 5.5 output a lot more. Which do you think has more promise?

Love when more RAM arrives in the mail. My poor-man's DGX Spark build (a Dell Poweredge R730) now has 160Gb of RAM. This will allow a Q6_0 quant on Qwen3.8-flash-next and a bump up in the Context Window. Should get 10-12 token/s.

A preliminary view of a second PCB done completely with Claude Opus 5.5. Only a first draft for review. This is to drive multiple ST3215 Digital Servo from i2c. A few things are missing but not bad Claude for first pass!

but I think that USB-C connector will need to move to th edge 😅

Better USB-C placement

Claude Opus 5.5 continues to amaze me. Claude Opus 5.5 created a 3D printable enclosure for an existing PCB. Then it created this promo video for it. The PCB, the printable STLs and this animation are 100% just from prompting in Claude Code.

Claude Opus 5.5 seems to learn really quickly. Here is the second Kicad Schematic I asked it to build. I didn't need to repeat all the feedback from the first to get a useful artefact. The more you use it for a task like circuit schematics the more it quickly understands.

It is probably because I have a system prompt for Claude not to repeat recent mistakes: github.com/DingoOz/prompts/b…

It came up with a novel-to-me way to print a DIN clip

So I prompted in Claude Code and it used Blender to render the existing STLs and added the annotations as a separate step.

This is my vibe right now. The game has changed for sure.

Letting Claude Opus 5.5 design actual PCB hardware. Prompted on Friday, sent to JLCPCB Friday evening and it is in Production Saturday morning (China time). A project idea I never had the time to complete. Now done in a single afternoon.

And every step of the process is visible to me.

My first Claude Opus 5.5 designed PCB by Claude Opus 5.5. This has been sent to JLCPCB for fabrication and assembly. Input: prompt >> Output: Assembled working board. Can you guess what it does and what I am using it for?

This board allows hot-swapping batteries on a robot and measuring battery levels. Never have to stop ROS2 and robot development to recharge a battery! It is compatible with QWIIC and Piicodev.

It took about 4-5 hours from prompting in Claude Code with Opus 5.5 to generate all the necessary files in Kicad. I'll report back in about a 6 days time when I get it if it works as expected!

This is a pattern for all future labs, I would love to see this the Robotics development space. EE and MechE labs of the future!

In 12 weeks, we built a research facility that is run entirely by AI. AI designs, executes, and observes experiments end-to-end across biology, chemistry, and materials science. We’re introducing SciUniverse: a benchmark that measures AI’s ability to do real-world scientific research.
