#MACVIM GREEN EXTRA CHARACTERS SERIES#
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. 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. 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. 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. 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 UPDATE#
Update Dec 2013 – Check out the forum at for the latest news about JeeLabs. 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. 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. 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. I can assure you that my interests and passions have not changed, and that I’ll remain as active as ever w.r.t. For a glimpse of of what I’m considering doing next, see this page. I’d like to think that I’ve played my part in this and wish you a lot of happy tinkering. 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.
Please don’t ever stop exploring and pushing the boundaries of imagination and creativity – be it your own or that of others.
For 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. 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. Your encouragement, thank-you’s, insightful comments, corrections and additions – I’m deeply grateful for each one of them. This is post # 1400, with over 6000 comments to date. Unfortunately, I really need to find a new way to push myself forward. I know from the many emails I’ve received over the years that many of you have been enjoying this weblog – some of you even from the very beginning, almost 5 years ago. But this weblog will remain online, and so will the forum & shop. There will be no new posts after this one. It’s also my way of announcing that I’ve decided to wrap up this daily weblog and call it quits.
A bit like my energy levels, I think :)īut this post is not just about reporting ultra low-power consumption. As you can see, the battery is getting weaker, dropping in voltage after each 25 mA transmission pulse, but still recovering very nicely before the next transmission:įascinating stuff. The battery voltage is also tracked, using a nice little trick which lets the ATtiny measure its own supply voltage. It’s running the radioBlip2 sketch, sending out packets with an incrementing long integer packet count, roughly once every minute: I’m writing this post while one of the test JeeNode Micro’s here at JeeLabs is nearing its eighth month of operation on a single coin cell:
