For everyone struggling with the SMD electrolytic capacitors (I know I was!). Here's a method I found working for me (using a soldering iron).
I'm using a 1.6mm chisel tip at 300deg C and soldering paste (plus a tiny bit of leaded solder). You'll also need some tweezers.
In this post I will document my journey of building a Eurorack sequencer from scratch. I will try to be as detailed as possible and include all the steps I'm taking. I will also try to include all the resources I'm using and all the mistakes I'm making. I hope this will be helpful for someone out there.
For the impatient: find the code here
