Most hobbyists start off with a cheap and nasty soldering iron which takes minutes to heat up, and provides no temperature control. Whilst a decent soldering station is a significant upgrade from a typical beginners iron, the cost can be prohibitive. Thankfully, GreatScottLab has put together a great instructable detailing how you can build your own fully controllable soldering station.
Not only is building your own significantly cheaper than buying a soldering station, but the process of building the electronics and 3D printing the enclosure provides a fantastic educational opportunity!
