Trying to get a hand on just how much case to sink thermal resistance I’m dealing with. Getting a temperature prob on the case to see what is the real case temperature.

In the exploration of my new programming toy. I’m throwing something quite old at it, an ATtiny13A. While old, not obsolete. The ATtiny13A is still in production and available in the 100,000s. And that did surprise me. But can I twiddle the bits in it from the new PICKit 5?

Curiosity can surely lead to some wasted time and a bit of a mess. Ever since I got the Canon imagePROGRAF PRO-4000 to teardown, the intermittent ink leak that caused it to be scrapped has puzzled me. I finally got a couple of hours to tear into the troubled ink tank unit to see what I could find.
Testing the OIVO IV-P5211B PS5 DualSense charging cradle. Tearing it apart to see what’s inside. Drawing up a schematic diagram to explore the workings of the device.
I’m using the ATtiny402’s USART module to output a variable from the microcontroller. This is geared more toward a debugging setup, as I’m only going to be dealing with the USART’s transmit section. Outputting both ASCII data as well as formatted raw data. And I discovered the MPLAB X Data Visualizer. Which makes the viewing of the raw data very easy.
