What is Your Choice for the Next "Experimenting with [Name Your Component]" Design Challenge

We have announced our Grand Prize Winner for our Experimenting with Polymer Capacitors Design Challenge, who will DSOX1102G Keysight Digital Oscilloscope. We had 7 other finishers who will receive a Tenma Pen Type Digital Multimeter. Congratulations to everyone who participated in this competition.

 

But what about the next Experimenting with [Name your Component] Design Challenge? What would you like to experiment with?

 

Please vote below.

    Incredibly nice Rachael! I loved this video.

    I voted for these things,

    though I was more thinking of experimenting with the kind of power BJTs that used in an amplifier design last autumn than of trying to make my own MOSFETs.

     

    On a completely different tack, 'Experimenting with Instrumentation Amplifiers' might be interesting.

    Yep I agree Doug! And here is the ultimate in experimenting..... make your own! Courtesy of Jeri Ellsworth:

     

  • Transistors - the component that makes modern electronics possible

    There are probably more transistors made than all other components combined.

    There are many parameters used to characterize transistors with lots of scope for test techniques.

    Have you ever used a "curve tracer" to plot transistor characteristics?

    Do you have a meter that can measure HFE?

    What is the weirdest transistor application you ever saw?

  • Inductors would seem a natural follow on from the Capacitor Challenge but are there any new technologies entering that field?

     

    How about circuit protection - I see there is a great new fuse holder called Littelfuse plus lots of learning about the correct type of fuse regarding characteristics. Might require a few fuses if non-resetable as this would result in descructive testing ! However the pack could also include resting fuses so the challengers can see how long they take to reset, do they degrade, overheat etc?

     

    The other area that doesn't get much thought is timing - crystals and resonators could be fun and a great opportunity to learn. Perhaps including some back-to-basics oscillator designs? Other may opt to check crystal accuracy in some homebrew way.

  • I miss good ole vacuum tube circuits, that would be interesting.

  • Given the special types of diodes, I think we could have a lot of very good experiments with the simple diode devices.

     

    Just look at all of the circuits that rely on diodes.

  • I think inductors could be a lot of fun to play with!
