  • I do not plan to do this but it was interesting to see a bit of insanity and science at the same time. I have wondered about combining chargers like this. Very interesting. I think it would be wild to split this and do ½ in serial and the other in parallel. Thanks again for doing this.

  • Ok. I will try to make that work.

  • Or maybe just nine as that is more standard level.

  • I would rather have 7 volts as the regulators often drop the power too much on my projects. I find 5V hard to use. Thoughts?

  • Very interesting article. Vape is something I am against, but facts are always good. I was wondering how all this works. I think building a miniature smoke machine has got my interest and doing it within the safe discharge levels has also my interest. I was thinking a big capacitor discharge might also be a variation. Charge the cap safely and then discharge the cap to avoid battery surprises.

  • Nice story. I like seeing care taken to work with electronics that we no longer build. Thank you!

  • Excellent display of engineering. We makers sometimes forget about heat and long running issues. Nice to see a study like this.

  • This is an interesting article. So far I have not needed lots of anything, but I need many of few. I have purchased complete sets as I hate not having little components. I have Sparkfun’s capacitor and resister sets. From others-lines suppliers I have complete sets of ICs, transistors, even more capacitor and resisters sets, and sets of various LEDs. So I would say that sets of items with an organizer and labels which I have purchased are more what folks might want. Thanks for the nice article.

  • I usually only buy those with headers installed. I hate having to source the headers and buy them. I can solder since I was eight, but I usually only buy things with headers. I am always plugging them into breadboards and building prototypes. I hate to do it myself and I am always worried that this time I will mess up the board–never do but still possible.

  • Order had exception on it. Have to tell SF where I will use it before they will ship it.

No public wish lists :(
