26 AWG solid copper wire: the perfect choice for hand-soldered Arduino projects

This post is my little token of appreciation for the 26 AWG solid core copper wire. Perfect for creating permanent version of Arduino projects, or if not perfect, then at least much simpler than wire wrapping and much, much more practical than using solder traces. Man, I love 26 AWG solid core.

Using a FLIR thermal camera to improve the taste uniformity of a tea-infused cake

Making a layer cake is a serious task. There are... layers... of complexity to it. Make a mistake, miss a step, and the whole thing can turn into a disaster.

Quick look: Voltage drift / instability on Ruideng RD6006 power supply

This post is a quick record of voltage drift / variations I noticed during recent experiments with using a MOSFET as a voltage-controlled resistor, where the MOSFET's Gate-Source voltage was driven by the Ruideng RD6006(W) DC-DC power supply.
