Now it's on right direction

A project log for SD card sized board, let's say "SDuino"!

Once I was excited to see Intel's announce that they will release "SD card sized computer" but it was not true. This time I made it true!

The previous "SDuino on wrist" was a bit hard to read its digit and Nyancat, so this time,,

I rotate 90 deg to read well !

The function and circuit is exactly the same (Lipo battery and charging circuit), but

I inserted a string of plastic sheet (actually it is SD card holder cut by scissors...)

and it is working as "very low-efficiency light-wave waveguide". When it turns green, battery inside is full, and will turn red during charging....
