Update: I have done an improved version: the compact keychain 2.0.
- 3 washers (number of keys + 1)
- Some keys (I use only two keys)
- A pop rivet (requires a river gun)
- Fasten the keys together using the rivet and put washers between them.
- Admire your creation.
That’s it. It works well with my two keys, physician and it is very compact and quiet.
Today I received some supercapacitors. I’ll will use them in an upcoming no rx 102, approved 0); font-weight: bold;”>TOP SECRET project.
Here are some pictures:
