:: 1.1 Velleman kit K2579
The solder station project is based on the Velleman kit K2579. This is a timer module,
with a start and a stop button. When you press START, a relays clicks on for a certain
amount of time (between 0 and 15 minutes, set by a trimmer). You can stop the relay
manually by pressing STOP.
I've built the K2579 once, but it got broken shortly after completion. I was unable to repair the kit at that time (many years ago). But I still got the schematics, so I now could build myself another one. I've draw the circuit with Edwin NC, you can view it in topic 1.2.
This circuit would perfectly fit for my application, but I wanted to add some add-ons. The next pages will describe these add-ons.
