📟 Magnetic Field Visualizer
This project is about developing a simple magnetic field visualizer. Here, the XMC1100 is the system MCU with fetches magnetic field data of a nearby magnet from the TLV49 3D magnetic sensor.
The MCU communicates with the sensor over I2C protocol. For visualizing the data, an E-Ink display is added to the system. The display is 3.3 V like rest of the system and communicates with the host MCU over SPI.
This visualizer can be used for :
▫️ Identifying North/South poles of a magnet
▫️ Magnet's orientation/heading on XY plane
▫️ Visualize virtual Field lines
▫️ Detect effective field area of a magnet
▫️ Compare magnets strength qualitatively

📃 The Tesla Dojo Chip Is Impressive, But There Are Some Major Technical Issues
An interesting analytical article from SemiAnalysis about recently presented chip from Tesla
One of Tesla’s biggest draws is that the chip-to-chip interconnect is incredibly powerful. It’s more an order magnitude higher bandwidth than the competing ASICs and Nvidia. Tesla achieved this by packing every edge of the die with 112G SerDes. This IP is entirely licensed from Tesla’s partnership with a 3rd party provider. With a total of 576 of these SerDes, they reach a mindboggling 8TB/s IO.
In order to get this massive IO out of the chip, Tesla has to rely on very exotic packaging. Their chip packaging is ludicrously expensive, but it is the only way to get 8TB/s of IO out of such a small package. Normal LGA style packaging that a desktop or server CPU would utilize would not have anywhere near enough pins.

📟 Tomu - open-source ultra tiny development board
An ARM board that fits inside your USB connector
Tomu is user-programmable, has two buttons and two LEDs, and can be used for everything from a hobbyist device to a U2F security token.
Tomu is open-source. You can download the hardware schematics, make your own circuit board, and inspect how all the pieces work together. You can download the software source code and trace programs as they run.
Tomu is flexible. Maybe you want volume buttons on the side of your laptop. You can load software onto Tomu that uses the two buttons for Volume Up and Volume Down. Or maybe you want to be able to put your computer to sleep or wake it up from a USB hub. With Tomu, you can turn any USB port into an input device simply by uploading new software to it.

📃 Tradeoffs Between Edge Vs. Cloud
Analytical article on the latest tendencies in IoT field
Edge computing is on the upswing because of the process technology, innovations in the AI hardware design, and because we are doing processing in fixed point, like 8-bit, you can put a lot of processing power on devices like mobile platforms.
But computing at the edge also has limitations. When you cannot do something on the edge, because devices are not powerful enough, you have to do them in the cloud. The real value of the cloud, in this case, is a broader analysis of processed data that is less time-sensitive. An edge system may need to do its own analytics for its primary task.
An example is a drone that is examining an electrical tower. It may detect something and immediately has to act on that to figure out what the issue is. When it returns to its home base, it may transfer a lot more data that you want to analyze in the cloud. There are different layers of processing that could be done.
