Making Braille Signs out of PCBs

[jg] recently passed some damaged Braille signs and took on the challenge of repairing them. Informed by his recent work on PCB lapel pins, [jg] immediately thought of using circuit boards for this project. He’d noticed that round solder pads made for uniform hills of solder, and this reminded him of the bumps in Braille.

 

He began by reading up on the standards of the Braille Authority of North America, which stipulates a dot height of 0.6mm. He loaded up the PharmaBraille font system and laid it out the dots in photoshop, then and imported it into KiCad and laid out the boards. When the PCBs had arrived from OSH Park, [jg] soldering up the pads (lead free, but of course) to see if he could get the hills to 0.6mm. He’s experimenting with different methods of melting the solder to try to get more even results

Building a PCB lapel

I had little experience with fabric, but building a lapel out of PCB seemed like something that might just work. PCBs are typically built with extremely high tolerances for its copper and mask layers and still acceptably accurate for the silkscreen.

PCB art is getting better and better every year.  This year, though, is knocking it out of the park.  In March, Andrew Sowa turned me into money.

More recently, Trammell Hudson has explored the layers of OSH Park soldermask and silk to create a masterpiece.

Now, we’re moving up to full-blown art. Blake Ramsdell worked with OSH Park to create a full panel of art in gold, fiberglass, soldermask, and silkscreen. It’s 22×16 inches, and it’s fantastic.
