Wasn't too familiar with DJ Hero. Took a look... dang. That would be an interesting and challenging project!

Thanks! Appreciate you saying that :)

Thanks! The image recognition is done by OpenCV which I highly recommend checking out.

Honestly, I'm pretty new to robotics and haven't had a chance to mess around with transistors. I was able to find some videos on solenoids and relays and that made it easy for me to get something up and running quickly.

The latency wasn't an issue though. Even on expert mode on TTFATF, I still had to program a delay to time everything up. But that's great to know for future projects if I need a super low-latency solution.

Appreciate you looking through the code and offering that suggestion. I'll take a closer look ;)

Also was not aware of the Ace of Spades robots. Just watched the video and it's epic!

Thanks! Actually had a similar comment on my video:

> Yes! I didn't realize this other robot existed until I was partially through the project and was doing more research. I loved their form factor so I used it for Jon Bot Jovi. IIRC, they struggled to beat TTFATF (they got 60-70%?) because their note detection software struggled to decipher long blocks of notes tightly together

Yes I'm a fan of his! Coincidentally, Stuff Made Here actually commented on this YouTube video. But I have been enjoying and learning from his channel.

Thanks for taking the time to write that. It means a lot to me and I'm really happy you're enjoying the videos.

Good call on the microphone. I'm still testing some things out so will keep that in mind as I produce the next few videos.

Thanks for subscribing and looking forward to hearing what you think of the next video!

Yes exactly! Thank you!!

I don't understand exactly what you mean. There were only 30 frames coming in per second that I could parse. Do you think there might be a way to get 60fps from the PS2 and parse that in the OpenCV code?

Thank you and I appreciate your subscription :) Hope to continue to entertain you in future videos!

I did think of ways to have alternative strumming, but there's something hilarious about it just mashing the strum button as fast as it can. And since the solenoid was able to handle it, I kept it as is :)

Agreed the sustained notes would be a bit of a programming annoyance, but if I had spent more time, I think I could have cracked it. I did get some MVP working for it but it was throwing some other things off, so I abandoned it in an effort to maximize accuracy.

The Raspberry Pi is doing the blob detection!

In terms of 97% and why not 100%:

> There wasn't any limitation from the mechanical perspective. The AI did a nearly perfect job of recognizing notes. I don't know exactly why it missed some notes, but my hypothesis is that it was the speed of notes in quick succession. If I do a follow up video with Jon Bot Jovi, I'll dig into it more!

Thanks!! It was super challenging but it was a fun time and the payoff of it shredding was well worth it

Wow man that's an awesome story. Sounds like it was quite the ride. Thanks for sharing!

A Go-playing robot would be sweet!

I think the biggest improvement for score would be implementing logic to hold down long notes and then implement star power at the ideal time. That would make a dramatic difference!

Lol challenging Boston Dynamics would be awesome

Ah yes. And it worked beautifully!

Thanks a lot!! Yeah it's an epic song and is so nostalgic.

Thanks!! Appreciate it

Hahaha

Will do, thanks!!

Thanks a lot!! Really glad you enjoyed

Thanks! Yes I love Mark and his videos. Huge inspiration for sure :)

Yes! But I don’t think that’d be as cool. I really wanted to replicate the motion of having to press the buttons :)

Lol she’ll love that

Haha thanks for checking out the videos! That company ended up failing. I was almost on Shark Tank again for my company DirtByMail.com (we were talking with the producers of ABC), but didn’t make it on.

Wow how crazy is that! That’s really great. Obviously I had the privilege to leverage modern tech with CV, but amazing that you were able to accomplish it 13 years ago!
