For a research project and demonstrator at HSLU university I have to measure voltage a DC voltage and current. For this I’m planning to use the Texas Instrument Texas Instruments INA260, so I had to quickly develop a software driver for it.
Implementing low power in embedded applications implemented can be challenging. Measuring current consumption is a first step to see if the software changes indeed have an effect on the current consumed. The PEmicro Universal Multilink FX debug probe comes with a useful feature to provide power to the target and the same time to measure the current consumption and to show the current used in the Eclipse IDE:

The question has been: If I buy such a 50 Watt cheap laser cutter from China, how many Watts does it really have? I have read all these stories that usually what is advertised is only the theoretical maximum I could get, and will not be realistic at all. This article is about how I tuned the machine and how much I got out of it.
