Week Four – Envelope Filter Build
This week went really well with the soldering. I got a chance to look back at my first build and compare the solder joints from the previous week to this week, and saw a lot of improvement. In fact, I’m a bit surprised that the confidence boost even worked.
I started my session by checking the parts against the parts list and testing needed parts with my multi-meter. Checking the colors or resistors is always a bit difficult, even with good lighting so the multi-meter really came in handy. I completed most of the soldering in two sessions.
I am currently looking for a 95 – 99% alcohol solution such as isopropyl alcohol or grain alcohol to clean the flux off of the printed circuit board. I’m using no clean solder, but it is still suggested that one clean the traces and residue on the board.
Next week, I will wire up the pots, switches and hopefully give it a test run.
