 ## Motivation
 
-I wanted a permanent, always-on control panel for my desktop that doesn't depend on the PC being awake — something physical that sits in the case itself. Existing software solutions require the OS to be running. By putting the management logic on a microcontroller with its own Ethernet connection, the panel stays functional for Wake-on-LAN even when the PC is off, and the display shows status without needing the host to render anything. It also gave me a good reason to work with Ethernet, async networking, and SPI displays in embedded Rust.

 ### Week 5 - 11 May
 Connected the modules, and ran some tests on them. Also did schematics, cleared some issues with connections,
 tested and moved every submodule into it's own spi channel( display - spi1, touch - spi2, w5500 - spi3).

 ### Week 12 - 18 May
-Ran extensive testing, and started software development with an http server ran, with OTP auth, to control device
-from the internet. Also testing some touch calibration and different refresh rates, to finalize software for the screen.
+Ran a full round of hardware bring-up tests on the board: ADC + PWM sanity check (joystick on PA0 driving a PWM channel on PB10), W5500 SPI diagnostics, NTP time sync over UDP, and touch/refresh-rate sweeps on the ILI9341. Once the I/O was stable, i started development on the OTP web server
 
 ### Week 19 - 25 May
 
+Switched the display to a new layout that shows CPU temperature, CPU / RAM / GPU usage as live bars plus the host IP, instead of the previous text-only stats screen.
+
+Wrote a small Rust agent that runs on the host PC (`telemetry-host`) and pushes telemetry to the Nucleo over UDP on port 9000. It reads CPU temp from `/sys/class/thermal`, CPU usage from `/proc/stat`, RAM from `/proc/meminfo`, and auto-detects the GPU usage source (NVIDIA via `nvidia-smi`, AMD via `gpu_busy_percent`, Intel via `gt_act_freq_mhz`). The same agent also listens on UDP 9001 for commands coming back from the board — it handles `SHUTDOWN` (tries `systemctl poweroff`, `loginctl poweroff`, `shutdown -h now`, `sudo shutdown` in order) and runs any other payload as a shell command via `sh -c`.
+
+On the board, finished a web management server (`wol_web`) on port 80 with TOTP authentication.
+After login you get a page where you set the target MAC address for Wake-on-LAN, fire the magic packet to the broadcast address on UDP/9, and send arbitrary shell commands to the host agent — the board forwards them over UDP/9001 to `telemetry-host`, which executes them with `sh -c`. The live telemetry coming from the host is also rendered on the page next to the WoL controls, with a small weather box.

+### Housing
+
+I added a 3D-printed housing for the display. I started from the [Housing display 3.2 inch TFT LCD display module ILI9341](https://www.printables.com/model/1435870-housing-display-32-inch-tft-lcd-display-module-ili) model and modified it to fit the Nucleo board and to add a hole for the Ethernet connector.
