Why You Should Take the Time to Build Yourself the Proper Tools
I came to regret that tonight. I bumped the setup, and managed to short the 15V power pin to the /LOCK pin, putting 15V onto all of the logic, and made both my Rb reference and power supply very cranky. This released the magic blue smoke from my Rb reference, which now has little use beyond being an impressive, but painfully expensive, heated drink coaster...
It isn't glamorous, and it doesn't feel like you're getting anything useful done, but the 15 minutes I just spent building this would have saved me a $50 part, and now it's sitting in my "connectors" junk box, ready to go the next time I need to probe a DB-9 connector for something.
