This project is a five-panel cap, with lights embedded in the brim, that reacts to an audio signal passed in through a standard 3.5mm headphone jack. As for how it works: it (mostly) doesn’t. Click the picture below for a feel of the current effect, then we can talk about why the video […]

Pictures: First picture is the best toner transfer I’ve been able to pull off so far. Spent most of the week trying to just get a resist going. You can still tell there are some breaks, but those should be fixable with a really fine sharpie. I’ve been experimenting with […]

Images: I finished up routing the traces for the lights in the brim. You can see the circuit in the middle picture. Note the lights don’t go all the way around the brim – see the problems section. I’m gonna forge on ahead as-is, but this might be a spot […]

Well, I think I arrived at a decent solution to the planar embedding: The issue is really those two pads in the middle. They provide a power and ground signal for the circuit. This graph is totally flat, and needs no jumpers, but I have to connect to those pads […]

IMAGE: Turns out open-source software can be a pain to use. The power is all there, but the interface is terrible and there’s been a lot of bugs to sort through. The embedded image is part of the trace layout for the circuit board, as well as a badly-done rendering of […]

1. Image or video: Boom. That’s the substrate I’ll be using as the backbone of the circuit. It’s in a ziploc, so you can’t tell the thickness, but you’ll just have to trust me when I say it’s super thin. It’s also incredibly flexible, to the point I had to […]

1. Image or video: What you see is the brim of a cheap hat I deconstructed. There’s a few things to take away from the way it’s put together. Firstly, the material is plastic – it looks like cardboard, but it’s a cheap recycled plastic material similar in composition to […]
