Introducing a minimalist style Printed Circuit Board LoRA trained on a dataset of 2-color, monochrome images of circuit boards and traces. This model has no electronic components, only the bare-boards! I tried using other LoRAs for circuit board traces, but kept getting halation, blurry lines, faces and other unwanted stuff in the output. Since I mainly make animations with Deforum, I really need consistent results and prompt engineering just wasn't specific enough for this style.
This LoRA works great with anything technology-themed and fills a gap in every base model I've ever used. I regularly have technology themes in my work and I've tried to get circuit board and traces from every major base model on civit.ai without any luck. Even with all prompt engineering tricks I've learned to date, I still always get random chips, VRMs, capacitors and other components popping up and 2D or Vector-image styles are simply Unobtanium. Prompting alone is not enough, in my experience.
If you like clean, high-contrast designs with solid colors and no glowing lines, bloom, halation, and OMG anything with no shadows, raytracing, depth, or other 3D effect, you should find this LoRA useful.
To use, put the file in your Lora directory and paste this text in your prompt:
<lora:PCBv2:0.5>
Adjust "0.5" between 0.1-1 to suit your needs. This will vary, depending on many factors. This model works well at any strength and worked well with every SD 1.5 model I tried.
If you find this model useful, please consider buying me a coffee:
More non-portrait LoRAs to come!
Description
More diversity in the choice of images in the dataset and the result is better traces, which is all I wanted. I also included some aesthetically pleasing CAM schematics as well as photos of more PCB with no components on them. I also reduced the amount of random dots appearing in output. In real life, these would be vias or contact patches, but they serve no aesthetic purpose, here. The annotation was also better, so you can specify traces on a circuit board, for example.
