Op-Amp-a-Palooza: What's Something Fun We Could Do with the Upcoming Op-Amp Contest?

Greetings Best Community Members in the Galaxy!

Op-Amps will be the next Project14 competition.  This will be a contest featuring low cost components.  There's so much that can be done with OpAmps: Amplifiers and buffers, measurement, active filters, voltage references, current measurement, audio vs RF vs HT, precision circuits low noise circuits making one from discrete components

We will be doing something a bit different with this contest.   You are free to choose whatever components but we'll be offering a kit with low cost components from as many as four different suppliers.  What we were wondering is if you had any cool ideas on what we could do to make this next contest more fun?  For example,  we recently had a Spy Nerd Contest that included cool spy gadgets as prizes.   What are your ideas on what you would like to see in this contest?   It could be a fun prize or something we would have never thought of.   The Op-Amps contest is suppose to start on February 14th but to accommodate some last minute planning we'll likely move the launch date to February 18th.

    Random thoughts: replace (or re-design) an existing circuit with a (different) op-amp. Break into categories (amplifier, reference, transconductance, etc) and judge based on the component count. e…

    A special prize for the best quality of the photos and videos of the project and as a prize any gadget that allows us to improve the quality of the photos and videos that we upload to element14 would be…

    Perhaps you can get Digilent to sprinkle some more ADP3450s around

    I got started early on a PWM controller for small servos using op-amps.  It was a good chance to play with KiCad 6 and I wanted to get some PCBs made before the Chinese New Year.  So I already have something in hand.

    Audio used to be all analog, but now it is often digital all the way from the microphone to the speaker.

    However there are all kinds of audio devices out there that might make interesting prizes:

    How about a podcast audio mixer? There are many types out there, but they might improve our blogs.

    Or How about a small MIDI keyboard.

    I can't recall any contest for autonomous vehicles. It seems like a big gap that needs to be filled.

    You can include other components to make a device.   The contest will be open-ended.

    Going through the boxes for things I had once started with op amps and never finished was a line follower vehicle project without a microcontroller. How about a remote competition of line following vehicles.
