Thanks to Rich Olson for sharing this neat method of making circuit boards! Check out his full blog post about it here.
I’ve “rabbit-holed” on various projects – but I may have spent more time trying to come up with new ways to make circuit boards than any other. Over the last few I’ve months developed several new approaches – this one is my favorite.
When you print on glossy inkjet photo paper with a laser printer – something interesting happens. The toner sticks to the photo paper – but doesn’t really embed itself the way it does into normal paper. Hobbyists have found it’s possible to transfer the toner to PCB blanks – and use it as a “resist” to make etched circuit boards.
What I recently figured out is that certain silver adhesive will stick to the printed toner – but not the photo paper. If you apply a few layers of the adhesive – it’s possible to make circuit boards of useful quality.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
