Congratulations to jancumps for Turn a standard oscilloscope into a solder-in one, jc2048 for P14 Prototyping Techniques: Attempting to Measure Op Amp Open-Loop DC Gain , and colporteur for I'm Board...Cutting Board to Printed Circuit Board! You are the first place winners and a $100 shopping cart.

The Circuit Prototype Techniques contest was a joy to watch and it was great to see so many of our regular members share their stories and individual techniques. We've listed a a few honorable mentions but really this was a solid batch of projects from top to bottom. From crazy eyeballs to stacks of schematics to reviving the love of 80s prototyping techniques, this contest had it all. After taking a look at this announcement, we hope you'll take some time to visit some of these posts and learn something useful in the process. We knew going in this was a popular topic among community members and this didn't disappoint.

Bravo to everyone who participated!

Getting quite frustrating finding a suitable PSU for the Pi 4 + MCC172 Measurement card.. the Stontronics PSU that is advertised as Pi 4 capable does work very well as a Pi 4 power supply, but has some noise. I can find (high-end) phone/tablet chargers that have a cleaner output, but they cannot sustain the demand from the Pi 4, and there are brownouts. I've yet to find any PSU that has both low noise, and can run the Pi 4 (with the measurement card). Figure-8 connector would be nice too, but that's just dreaming : )

I'm going to try and compare the adapter above vs a Lenovo laptop brick with the DAQ HAT from the road test.
