Simplight and prototyping

I started working on a new project tonight.  I’m going to build a compact, cheap LED light that runs on a single AA battery.  I’ll be using the MCP1640 voltage regulator booster from MicroChip.

I created the Eagle-Layout for it tonight and ordered a test board from OHSPark to verify the layout.  I also created a SOT23 to breadboard adapter and ordered 3 of those as well.  That will make it easier to prototype the chip and figure out how to set it up.

I also made a variant of the TO92 package for Eagle.  I find it annoying to bend the pins for transistors when putting them in boards.  I can’t think of a good reason it’s needed so I built a straight layout for the BC517.  I added it to the test layout board that I ordered.
