Your encouragement, thank-you’s, insightful comments, corrections and additions – I’m deeply grateful for each one of them. I hope that the passion which has always driven me to explore this computing stuff tied to the physical world technology and to write about these adventures, have helped you appreciate the creativity that comes with engineering and invention, and have maybe even tempted you to take steps to explore and learn beyond the things you already knew. Please don’t ever stop exploring and pushing the boundaries of imagination and creativity – be it your own or that of others.įor those visitors, here’s a quick summary of the recent flashback posts, to help you find your way around on this weblog: In fact, I sincerely hope that these pages will continue to encourage and inspire new visitors who stumble upon this weblog in the future. There is infinite potential in each of us, and I’m certain that if we can tap even just a tiny fraction of it, the world will be a better place. I’d like to think that I’ve played my part in this and wish you a lot of happy tinkering. For a glimpse of of what I’m considering doing next, see this page. I can assure you that my interests and passions have not changed, and that I’ll remain as active as ever w.r.t. The whole point of this change is to allow me to invest more focus and time, and to take the JeeLabs projects and products further, in fact. Following the advice of some friends I highly respect, I’m making this last weblog post open-ended: it’ll be the last post for now. So let’s just call this a break, until further notice :) Maybe the new plans don’t work out as expected after all, or maybe I’ll want to reconsider after a while, knowing how much joy and energy this weblog has given me over the years.
#MACVIM GREEN EXTRA CHARACTERS UPDATE#
Update Dec 2013 – Check out the forum at for the latest news about JeeLabs. One of the really fun things I always like to work on, is to push the envelope on power savings in the JeeNode.
#MACVIM GREEN EXTRA CHARACTERS SERIES#
Here’s the most primitive approach, inserting a multimeter in series with the power supply to measure the static current consumption: It all started long ago, but over the years, I did refine the measurement process as my insight and instruments both got better. Only static idle current can be measured this way.Īnother approach was to use a second JeeNode as power consumption tracker with some extra circuitry, to measure the voltage drop repeatedly: The big problem with this is that a multimeter is far too slow to really see what’s going on.
This design can capture spikes by performing lots of repeated measurements, and in this particular case it even had a fairly large measurement range of 1 ♚ to 60 mA. This was done by using two separate sensing circuits and switching between them as needed.īut the real breakthrough came mid 2010, when Jörg Binkele sent me an oscilloscope snapshot of the voltage over a small series resistor.
