Few months ago, I have installed GTX 1060 ti 6GB on desktop PC for using hashcat, but I found out that I rarely used hashcat to crack hash keys. Thus I decided to use AWS for cracking hashes. Kali (2019.03) distro is already in AWS market store. I selected US-West (Oregon) region with GPU enabled instance. I am using p2.xlarge and p3.2xlarge instances on Kali ; those are generally turned off and fair enough for my purposes.
It costs 0.9 CAD/h to 31,218 CAD/h with the Pay-As-You-Go rates depending on performance. The entry option is p2.xlarge(1* Tesla V100, 4 * vCPUs, 61GB RAM), and the highend option is p3dn.24xlarge(8 * Tesla V100, 256GB GPU Mem, 96 * vCPU with 768GB Mem)
Before I found out what Fritzing is, drawing connection map is time consuming work. This tool is intuitive and ease-to-use. We can import libraries for BeagleBone Black here.
We can manipulate brightness of LED by implementing Pulse Width Modulation(PWM), thanks for the Python, integrating these modules were not too difficult. There are two buttons between circuits, it modifies Duty Cycles to change the LED brightness.
As Raspberry 4 is delivering form China, I turned legacy little gadget into retro gamebox just for fun. It could not too complex, but there were some trial errors as always.

Most of setting can be left unchanged, but there might be some madatory changes required depending on environment.
setting:configuration->raspi-config->1.change user password setting:configuration->raspi-config->2.network options->WiFi-setting (need to make sure that the password for WiFi can not have a special character @) setting:configuration->raspi-config->5.interfacing option->enable ssh
After rebooting, then install the lightdm for autologin $sudo apt-get install lightdm setting: configuration->raspi-config->3.boot options->4.desktop autologin
If HDMI interface is default for sound, there is no issue but when using 3.5mm analogue audio out, it requires additional configuration changes.
To get audio through the 3.5 jack: Retropie configuration > Audio > select option 2 (headphones – 3.5mm jack) > OK > restart system
