Power Measurement with the PEmicro Multilink Universal in Eclipse
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:

tinyK22 Board Rev 1.3 released
The tinyK22 board is a tiny micro controller board we use at the Lucerne University of Applied Sciences and Arts. It is used in many research project, used in lectures and labs and used in most student projects. Because there was no small and breadboard friendly NXP Kinetis board with a debug interface available, we developed one featuring the NXP K22FN512, named the ‘tinyK22‘. Because of the success and high demand we stated a new large production run and used this to upgrade the board to the new Rev 1.3: you might notice already the color change :-).

DIY Portable Video Conference, Sharing and Teaching Device
COVID-19 is by far not over, and in Switzerland the infection rate is going up again (2nd wave?). During the spring 2020 semester university lock-down we moved pretty much everything to a ‘distance learning’ setup. With that experience and with the request to prepare for the fall semester, I have constructed a DIY conference and teaching device which should make things simpler and easier: a combination of video camera, speaker phone and a muting device:
