I built this because I kept stopping to check by rack
Built by a SeaSucker user
Kraken Rack Monitor started as a personal side project after I bought a vacuum-mounted bike rack and realized I had no way of knowing whether the vacuum mounts were still secure while I was driving.

The Story
From one nervous first drive to a real product
Last fall, I bought a vacuum-mounted SeaSucker bike rack so I could transport my bike without installing permanent racks on my Mustang. It worked great, but the uncertainty took the fun out of the drive: were the vacuum mounts still secure?
The first time I used it, I even had a friend drive behind me the entire trip, just in case. The rack itself was doing its job, but I had no way to see the vacuum indicators while driving.
So I built a small monitoring system for myself. It monitored the position of the vacuum plungers, showed their status on my phone, and alerted me if one moved past the alert threshold.
With that in place, the rack finally felt complete. I still installed and checked the rack properly, but now I had extra visibility while driving.
Reddit changed the plan
I shared the prototype. People told me to keep going.
I posted a video of the homemade prototype on Reddit expecting a few comments. Instead, it got almost 800 upvotes and more than 100 comments. A lot of people recognized the same feeling and encouraged me to protect the idea and make it real.
