    I would like to present but don't know the best time. Should there be a standardised/recommended best time/place?

    @rajputaman04: contact me via e-mail kgracey@parallax.com and let me know your idea - we'll schedule it in.

    The same power pole hit two weeks in a row. Gas, liquor, EBT, deli, boat, BOOM!!! I never realized the power pole was right outside the front door.


    This did not work even in a Bond movie.... Think the operative words here seem to be liquor and boat...

  • Are there no more videos? None from last week.
    Any scheduled from this week?

  • I'm currently prepping the videos for this week for posting. Check back later today; I know this is very important to all of us!

  • Hi

    I've looked everywhere and cannot find where you have hidden the live forum zoom videos.
    The last posted in post 1 of this thread was for January 27th two whole weeks ago.

    Sorry to make you look around, Dave. We have a YouTube Playlist for the P2 Live Forum (click in the hamburger in the upper right corner to see the other videos):

    I've become too busy at Parallax and need some help, but I have no time to train anybody to help me. Sort of a management problem, I guess.

    I have posted the last two videos, but I've also fallen behind. This weekend I hope to come clean on my duties and get all of the missing videos posted! I think I'm only three or four videos behind.

    Ken Gracey

  • Hi Ken

    Thanks- appreciate times are difficult.
    I'd volunteer to come and give a hand for free if I lived in the US.

    Dave

  • Thank you Ken for your efforts on these. My current employment makes attendance impossible.

    Yes, thank you Ken. I also can't make it to most of the meetings, but it's always nice to be able to see the video afterwards.

    Ken, Let me know how I can help.

  • Registration link for JonnyMac's Spin2 for Beginner's Series with XBee!

    Optional materials:

    (2) XBee Series 3 PCB Antenna Low Power or (2) XBee Series 3 PCB Antenna Long Range
    (2) XBee 3.3V/5V Adapter Boards or (2) XBee SIP Adapters (or a mix of these)

    I often recommend the XBee USB Adapter for configuring the XBee modules, but it may not be necessary. All XBee modules (including the newer Series 3) are configurable by the host microcontroller. Further, the XBee Series 3 are also discoverable and configurable using an iPhone or Android phone app.

    Ken, the JonnyMac Spin2 series YouTube videos are kind of long and time consuming to find the part one wants to watch for reference for the quickbits etc.
    So it's easier to find what people are looking for, would you like to post the time stamps for the videos? I have them if you want them.

  • There is a way to add chapters: https://www.tubics.com/blog/youtube-chapters/
    But who should/can do this. For sure not Ken. It's timeconsuming.

  • Time stamping is a work in progress. It has been happening from oldest video to newest. It will catch up to the current week soon.

  • @dnalor Thanks for the link. Will implement that.

  • I'm just saying, I watched all the the JonnyMac series videos 2 -7 on YouTube and recorded the timestamps for myself. I was just offering them because maybe someone else wants to save themselves about 15 hours of viewing to get them. That would mean about 10 minutes of work for whoever posts them to those videos. If someone has the interest and access to do that with these timestamps I'm offering them. Otherwise doesn't matter to me. I already have them.

  • For example:

  • Hi @Patter
    FANTASTIC !

    Thank you so much for sharing all those timestamps.

    Being in Europe I'm in the group of people rarely able to watch live, and rarely having enough time to catch up later. The timestamps really do help.
