For the full description of this project, please consult this post on my website.
I also have 2 videos. The first one showing the project operating a small LED without any problem. The second video shows the

On the second video, the power supply (HPK-PM01) was not in used yet. The power is provided by the 5V serial connector.
I do not have any idea yet what the problem is. Do not hesitate to contact me if you have a clue of what the problem can be. I'm most likely missing something related to high voltages and noise.
