Reworking a Dell Latitude XT in 2024
Intro
I had an old Dell Latitude XT (first generation) in my posession since... quite a long time. One of the first tablet/convertible laptops by Dell, released in 2007.
It was quite a nice machine, but it suffered from multiple issues. On the one hand, the ULV Core2Duo and internal 1 GB of DDR2 memory are nothing to write home about - but the biggest problem in my opinion -

RAK3172T in Arduino
As the RAK11300 did not really match my requirements (it uses way too much energy), I looked further and found the RAK3172 which is based on an STM32WLE5CCU6 - an STM32 chip which usually include good powersaving modes. As with the RAK11300, I did not want to go down the Wisblock way and designed my own breakout board:
This was act

Turing Pi 2 - Retrofitting an EMC2301 Fancontroller
The Turing Pi 2 (v.2.4) has actually some secrets that just start to get uncovered. Looking closely at the board, you will find the red marked area with what seems to be an unpopulated 4-pin fan header (J16) and an unpopulated IC spot (U109).
These spots were, as found out by Sam Edwards (CFSworks) actually a place to install Molex 47053-1000 4-p

The Turing RK1 Compute Module is powered by Rockchip RK3588 SoC. This chip utilizes an 8nm LP process and boasts an 8-core (Cortex-A76x4+ Cortex-A55x4) 64-bit CPU, capable of speeds up to 2.4 GHz. Incorporating an ARM Mali-G610MP4 quad-core GPU and a dedicated AI accelerator NPU, the Turing RK1 can ...
