Raspberry Pi and Raspberry Pi Pico Team Up for Robot Lawnmower Project
This may look like a normal robot lawnmower, the sort that trundles mindlessly around suburban lawns all over the country, but OpenMower is more than that, thanks to the clever use of two Raspberry Pi boards. The brainchild of German tech entrepreneur Clemens Elflein, and reported on by Hackster, OpenMower upgrades the internals of a standard robot mower to make it smarter using a Raspberry Pi 4, and the $4 Raspberry Pi Pico.

Reverse-engineering the LM185 voltage reference chip and its bandgap reference
Many circuits, such as a computer power supply or a phone charger, require a stable voltage reference, but it's harder than you might expect to keep a voltage stable when the temperature changes. One integrated circuit that does this is the LM185.1 I looked at the die of this chip and found some interesting features. The same silicon die is used for three different integrated circuits, using tiny internal fuses to change its functionality. The chip uses a special circuit called the bandgap reference to keep the voltage stable even if the temperature changes. In this blog post, I'll discuss the circuitry of the LM185 and its implementation in silicon.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
