I intended to hot glue it as well, but coincidentally it fit firmly. The lighting circuit was wrapped in shrinktube for insulation. The wire supports most of the weight, while the glue keeps it from shifting. I used a clever mixture of wire and hot glue to secure the bulb in the bezel. A hole saw created the circular opening, and the paint job was created with the same method as the nameplate. The bezel was constructed out of two drive bays, welded together with acetone. This will prevent the paint from tearing around the edges.īy masking half the nameplate, a dual-colour effect can be achieved. Remove the letters when the paint is nearly dry to the touch, but still tacky. Mask off half the nameplate, place the digits on the other side, and have at it with the spray paint. I've found the knife works well to separate the layers. Once the letters are cut out, carefully peel the masking tape off the paper. A sheet of cardboard underneath will prevent damage to the working surface. I stuck a piece of blue painter's tape to the backside, and slowly cut through both the paper and tape with a sharp hobby knife. Yes, I know I used Arial, but only because I couldn't find Helvetica at the time. Print out a set of large Helvetica font letters in reverse. The components attach nicely to the single chip, and the whole thing is small enough to fit through the opening in the light bulb. The circuit is so simple, I decided to dead-bug it. The dual op-amps create a relaxation oscillator, which make the LED slowly fade in and out over a period of about five seconds with the values given. It doesn't make much difference, but I find gloss easier to work with. I would say I used flat black paint because the glass provides specular highlights, but really I just ran out of gloss. This will block extra light behind the lens. Once the gel is set, mask off the front of the bulb, and give it a heavy coat of black spray paint. ![]() A ringstand or roll of tape works well for this. When fully melted, place it upright to cool and harden. Once liquid, gently stir it to help remove air bubbles. Melt the gel with a hot air gun, or by boiling it in water. Cut up a few chunks and shove them into the bulb. I tried polyurethane, gelatin, paraffin wax, and even epoxy, but one clearly stood out as the best: candle-making gel. It needed to be clear, easy to use, and stable enough to not degrade. I tried many different materials, looking for a substance with the right properties. Next we make a lens to focus and diffuse the light. Rinse it out with a bit of distilled water to leave perfectly clean glass. I went a bit further and ground the sharp edges down with a diamond rotary tool. Who ever though beige boxes would be appealing? Not to worry: help is on the way!įirst, we need to hollow out the bulb.
