This DIY kit will help with your soldering skills, while you learn about the standard 555 timer IC.
The kit learns you how the IC can be used to get a set time for powering the relay ON.
It intergrades a voltage-follower NPN transistor and Zenner as a stable voltage regulator.
So you can power it with a wide voltage range and no need to worry about the timing varying between the on-off times of the Relay.
