Contact me

I'm not looking for any PCB manufacturing or 3D printing sponsorship currently.

For any other sponsorships, please email me.

I do not do any engineering consulting, freelance projects or contract work.

I cannot also recommend anyone else.

I won't be able replying to any emails about personal firmware, hardware or debugging questions.

If your question is related to a specific video, please post a comment in that video. You might get a faster response from someone else, get more than one reply with various viewpoints and also help someone else with similar issues.

If your question is a general technical or debugging question, I recommend the following public forums to post your questions instead. I use them myself whenever I am stuck.

I do not have all the in-depth knowledge beyond certain tools and technologies shown in my videos and open source repositories. I wish I could help with everyone's technical questions, but sadly I simply cannot. Thanks for your understanding.
