Challenge: A key defroster for opening bike locks in winter. Answered
So I live in Montreal, winter is long here. Every morning opening our bike locks is problematic. We fixed it partially with lube, but this post is not about these solutions.
I have been looking for a device that could heat the frozen core of the lock. You can see an image attached of a product not available anymore to get the idea. I guess it was not working very well...
I have zero knowledge in electronics/electricity. I thought this question could be interesting/challenging for some of you.
So ideally the gadget would be:
Small enough to be carried on the key chain or in a commute bag.
Able to be inserted in any type of locks
Built with a safe way to prevent unwanted switch on (to avoid burning bags/pockets/houses...Lol)
Able to produce enough heat to defrost the lock
Rechargeable would be best (USB best best), capacity of 5mn maybe to operate twice a day...
Reasonably quick to unfreeze the lock, so you don t freeze yourself (That s why I abandon using hot pouches around the lock, pouring hot water will fix it quickly but then it will freeze again)
As I said, I don t have the skills to even begin to find a solution, but I saw a lot of smart stuff here and I am curious to see what you guys would answer to that. My guess is that it must be very difficult, if not I can t see why a similar product is not widely commercialized. I think a lot of people would buy it.
Thanks for the reading, I hope I picked your interest. Have a good day.
