Doing a few initial tests of the ATtiny402 in low-power states. And some of the complications involved in measuring intermittent tiny currents.

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?
I’m trying out a tinyAVR 0 series chip, the ATtiny402. Seeing as all my small pin count microcontrollers seem to date to over 10 years ago. I wanted to try something with a bit more modern release date. So this is a getting acquainted with the tinyAVR 0 family, well the 8-pin sibling.
I’m putting the Zhenyu 5-color fully insulated banana plug kit to use. Digging in a bit on the quality of the plugs. Noting some of the strong points and some of the shortcomings.

Wondering if there really is any difference between solder wicks. I decided to do a comparison of a few. Turns out there are differences and enough for me to have a favorite.

Now that I’m finally happy with the power supply. It’s time to move on to making it work. As the constant current mode will work in a different manner than the other 3 modes. And it should be the simplest. I’m going to tackle that first. Also testing to see what kind of temperature drift I’m going to have to deal with.
