We're stuck on the USB portion. Currently, the working version using USB needs to install drivers na medyo complicated ang paginstall. The one we're working on does not need any drivers...plug and play na. Unfortunately, we still haven't received the ICs for the USB plug and play functionality. Mga 1 oe 2 weeks wait pa siguro, galing kasi US e, nasabay sa Xmas rush.
Thanks for asking, but do know that we haven't given up on this project yet as many of us will benefit from this.
Happy New Year pala!
