I have this idea in my head wondering around for years about a mechanic cold storage/wallet device. The device is build of metals (steel, alumium, brass, copper, silver and maybe some gold or platinum) and glass, no electronics, plastic or paper. As long as it is not stolen or burns in a fire for several hours it should last for many many year (100+). You can setup the device all by your self by hand, your own public and private address so nobody, no even the maker of the device has ever seen or know address or private key. It can be used for any crypto coin as long as it supports a mini private key format (30 characters).
It should be your "life saving" device, set it up, place it in a safe or nice place and when you have some BTC for example you want to save/secure transfer it the address you gave the device and you can check balance on line any time. It is not intended to do transfers with but saving/secure storage for long term.
The design and style is going to be somewhat modern-punk-steam SAFE and has several cool security feature (one of them is something like a Cryptex). They will be of high quality build and materials and each device will have an unique serial number. An extra idea is to make accessories to "pimp" your device to make it even more unique. Besides storage of the address and privatekey there can be an option to store several of your physical coins (like Casascius, Leleana, etc).
I am working on some small drawings now and have an idea who can make the device (2 manufacturers/undustrial designers and 2 artists). But before I going to spend many hours on this project I was wandering if there is interest in such a device. It's going to be expensive but also very collectable and valuable, sales price maybe between $500 - $1500
Please let me know what you think of my idea and if it can be a success. Any suggestion, feedback, idea is very welcome.The picture below inspired me, but it's going to look different:
