Key ring

Are you curious about how electronics work and want to try soldering? The Keychain kit is an ideal choice for a start. After assembly, you will have a small functional LED flashlight that you can always carry with you - for example, on your keys. The simple construction and clear instructions make the kit a suitable project even for complete beginners.

Information

For assembly, we will use a soldering station or soldering iron, which we will use to melt tin at temperatures of 250-350 ° C. Therefore, it is very important to be extra careful not to burn yourself.
