Dry Martini WiFi operated neon sign


The allure and aesthetics of Neon Signs are indisputable but if you ever research the subject, real Neon signs are expensive and complicated to make. You have to heat glass tubes filled with color gases and apply thousands of volts. Fortunately there are now continuous led strips that could do the job really well. This project shows a simple method to make your own Neon like signs with a 3d printed frame, no acrylic and glue involved. And, better than that, you can operate the neon sign from your smartphone or browser.
