  1. What about connected more super capacitors in parallel so that the voltage drop to 2.5 volts takes longer . You should have showed that.

  2. I sell a low-cost breakout board for the LTC3108 on my website (link below). Dave, I would love to send you a free sample if you are interested. I am a big fan of EEVBlog, keep up the good work!

  3. Its such as you learn my thoughts! You appear to grasp so much approximately this, like you wrote the book in it or something. I believe that you just can do with a few to force the message home a little bit, however other than that, this is fantastic blog. An excellent read. I’ll definitely be back.
