So it turns out not only was the wrench not needed, but if it was, I got the wrong kind. All of the watches I’ve dealt with are opened by prying off the backing. This is how I’ve destroyed a number of screw drivers, so I thought a dedicated tool might do a better job. Turns out I was wrong. This wrench is for “jaxa” style watches which have little grooves on the backing which line up with the wrench. The back is then unscrewed.
6 well spent.So, I got my watch and watch case wrench today and decided to put them to use.
Today was my last first day of school, and when I was taking my bi-annual trip to Staples, I figured I’d pick up a binder to keep all of my data sheets and notes in order. I plan on actually documenting this project!
I realized today that I2C is a universal(ish) standard kind of thing, and if possible, it would make it really easy if all of my components were I2C compatible.
So, I’m going to need a case for my watch to go into, so I ordered a cheap Casio watch off Amazon. Nobody seems to sell watch cases for hobbyists, so I guess I’m just going to have to go about ripping apart watches until I find one that will work.
So I realized this morning that I’m not going to have quite enough I/O pins to drive all of these LEDs. If I set it up like this:
I spent about 6 hours today racking my brain trying to find parts that will both do what I want and feasibly be used in both the prototype and final version.
I’ve made a few different time pieces since I started working on custom electronics and decided that I want to seriously “step up my game” by building something that is at the moment completely over my head.
