NYbill puts up a ‘Lost Episode’ recorded in October, 2016. A comment for Ep. 2369 asking if I have ever built one of the many Transistor Kits available jogged my memory. I still had the recording so, I’ll just throw it up. I’m not sure how many pics I can find for the episode. I’ll put up what I can.

And just for Mike Ray, I’ll leave in some bench noises I would usually edit out. ;)

The soldering vice being used:

The kit (This looks like the one I ordered. But, it's been about a year gone by now. This one shows firmware running on the chip in the pics. You can take a gamble on it if you’d like):

New Version

FYI: Seems there is a new version of these kits for 2017. There are multiple options of ordering just the kit, just the parts, or fully assembled boards. I might pick up the $16 kit with the plexiglass case just for fun.

On Aliexpress.

I still plan to try and flash this 2016 kit I have. Then I can do a followup to this episode.
