Hi Friends,

We are nearing the Arduino / MIcrocontroller day of learning with Mitch Altman. We will be meeting at 10 AM CST USA time this Saturday, Sep 26, 2020.

The session will be 4 hours long, plus discussion/questions after. I will give a brief update on OSE and our current plans first thing - and then we'll go right into Mitch's 4 hour session.

You will need a laptop with Arduino IDE software (it's also found on the OSE Linux live USB if you have one), and the parts kit/tools if you are building along with us. You can also get the parts kit later if you don't have it, and are inspired to build yourself.

After Mitch's session, I can stay on and go over any build questions if you ordered the D3D Universal 3D printer kit, and also answer any other questions that you may have.

We will also record the session - so you can view it any time later if you miss any of it.

I look forward to it - see you Saturday.    Thanks,
