What better thing to do on a cold autumn day than to curl up with a nice warm soldering iron.
Join me as I grab a random kit from my pile and do a nice leisurely kit build.
Today's randomly selected kit is a function generator - basically a test signal generator.
This kit only cost about $2.
No surprise I found it on e-bay (https://www.ebay.ca/itm/DC-12V-25V-ICL8038-DDS-Signal-Generator-Module-IC-DIY-Sine-Square-Triangle-Wave/322859593858)
That other less impressive signal generator was another kit build, which you can see here: https://www.youtube.com/watch?v=TvfvN-0VwEE

This isn't the only way to do it.
It's probably not the best way to do it.
But it's how I do it.
