Hey everyone!

As you know the Design Lab residency has officially ended, and as of last week I was scrambling to get the noggin I have been working on for the past four months fully functional.

Luckily on Friday, literally the last day of the residency, Ed and I were able to get the Barnabas noggin to function as intended. The two issues from last week, not getting power from the barrel jack and the board not being recognized by Arduino (or my laptop in general), have been fixed.

Like I suspected, the board was not getting power from the barrel jack due to a burnt out diode. As soon as that was replaced the board received power as expected. The other issue it turns out was due to a very silly mistake on my part. I had linked the Tx of each chip to each other and the Rx of each chip to each other when they should be swapped. Luckily some McGyvering let us remedy the situation;

So what comes next? Well I don't intend to stop giving updates any time soon, as there's a lot that still needs to be done before this board is truly ready for production.

So until next time,
