JeeLabs: Micro Power Snitch, part 6

And you thought the MPS was finished, or perhaps abandoned, eh?

This week resumes the development of a little LPC810-/RFM69-powered setup which runs on parasitic power, harvested from either phase of a current-carrying AC mains wire.

To summarise, the last step in the project I went through a few weeks ago, was to create a PCB for it. Here were some builds, with all the hacks and hooks added to try things out:

As it turns out, I had made so many mistakes, one after the other, that it really set me back, irritated me to no end, and kept me busy with complete silliness… but all is well again now.

The articles in this week’s “back in business” MPS episode are:

• The PCB that got everything wrong– Wed
• Back on track – now the hard part– Thu

And with a bit of luck, by next week I’ll have figured out how to send out brief RF packets on an ridiculously minimal energy budget. Because that’s what “The Snitch” is all about!
