  • I created an Anlog Clock demo using Mark’s example code and graphics primitives from Jim Lynch’s tutorial. Youtube demo and source at:

  • I use the USB dongle to download data from the iButton to laptop. I might add a feature to download straight into the data logger programmer in the future. I have not had a need yet to leave the iButton in the field long enough to run out of sample memory to warrant the extra complexity.

    I think Amazon may have a better approach with their Lightning deals and deal of the day. I think a lot of traffic would be generated by people coming in to see what happens to be on sale each day…

No public wish lists :(
