after about 2 weeks of getting components together from Digikey and other sources (for emitter, battery holder, and slide switch), and designing the schematic and routing the board as well as etching it and a lot of teeny soldering...the prototype is finally done.
my girlfriend needed a flashing indicator cause she is on track and cross country and she runs at night and doesnt feel like getting run over. also, she has a thing for blue.
i'm still trying to figure out how to design the cover but the electronics will be coated in a dome of clear epoxy...or maybe matt epoxy to scatter the light. i think it's bright enough that it will distract drivers and cause accidents, but thats not my problem : )
it flashes at about 1.5Hz at 15% duty cycle. which means it runs forever and a day on 1 x CR123A cell.
i'm still trying to figure out how to attach a clip to it and how to design a good outer casing.
i'd prefer it run off a cr2, and i'll prolly make a smaller version of it that is somewhat more flat than this, i think the cr123A cell makes it too deep and awkward to attach to anything other than a belt, i dunno if a cr2 cell will be able to provide enough energy though. that remains to be seen. in the mean time i'm testing its runtime.
this is actually Rev2...Rev1 had the components much more spread out and i had to reroute the board to make the components much closer to account for the smaller version i'll be making in a while with the CR2, i think thats as tight as they'll get with my skills. but i'm having prototypes quoted atm...solder mask and all. this ended up being a neat little project.
any input welcomed, thought i'd share my excitement.
