As mentioned in an earlier post
I'll try to do one small PCB project every week and then send for PCB's of it every Monday.
During the last couple of years I've made PCBs in different shapes. Square, Rectangular, Square/Rectangular with round corners, Circular, T-shaped, "Flower"-shaped with arms like RetroTime PAW and boards with various cutouts. But I've never done a triangular or hexagonal board.
So this time I'll do a triangular design. An equilateral triangle is a triangle in which all three sides are equal and I want to have it as large as possible in a 5x5 square PCB. So by rotating it 15 degrees inside the square I can get sides that are 51.7 mm long instead of the 50 mm I get when having the pcb straight along the bottom edge of the square. I admin that the gain is very small, but why not? :-)
So, I've decided the shape of the board and now I need to fill it with some functionality as well. Hm.... I know it sounds a bit silly to first the decide on the PCB and then try to come up with what it should do. But why not - the PAW project is all about doing new things in a new way,to boldly go where no PCB designer has gone before. :-)
I'l leaning towards putting three lines of 10 pcs of 0805 smd leds each from the corners in towards the center. And then make some kind of three-person game out of it. Maybe some reaction-time based or maybe something more like ping-pong... And then maybe have a 8 or 10 mm led in the middle as some kind of signalling or common led. I dunno. I have to think about it a bit more.
I could also put a small microphone in the middle that reacts to sound and make something like a three-band VU-meter that will pump the "bars" in sync with the music it picks up.
Well, let's see what I end up with. The week is still young.
