PIC controllers like most modern controllers have intensive power saving modes. Most hobbyist don't use them unless it's an application requirement.

Energy harvesting Device.
But one day I will hopefully be designing products, and by then energy use WILL matter and matter alot, the more time goes by, the more energy saving will matter.
Thats partly my point, Pics do have sleep modes, but unless you pay out for a REAL ICE and use a pic32
The MPLAB REAL ICE POWER MONITOR enables designers to identify and eliminate code that consumes high current, in real time. Combined with the MPLAB REAL ICE in-circuit emulator and MPLAB X IDE, this development platform allows users to measure, graphically profile and optimize code power consumption for all of Microchip’s more than 1000 8-bit, 16-bit and 32-bit PIC® microcontrollers. Additionally, it offers unsurpassed micro-Amp current measurement, with an overall dynamic range up to 1 Amp, and a voltage range of 1.25V to 5.5V, making it ideal for a broad range of battery-powered, digital power-supply, motor-control and metering applications.
Hmmmm, ok sod it! I will keep loops and just use a car battery for my designsThat would mean abandaning loops-inside-loops programming style in favor of sleeping and interrupts
I didnt know it was for all chips!the bit I read only said 32bit, stll its a hefty price all the same, with EFM its built in and free (ok no such thing as free, but you know what I mean).If you have REAL ICE this works on almost everything but you don't need fancy tools to do basic power tracking.

Remember:
Crusades are great motivators but are often misguided paths to the future.
This has been done for years in recreational vehicles like boats and campers.or there will be a day when we have two power circuits in a house, one low power for LED light etc, and a higher power one (240V).
So my thinking is, as electric keeps going up, then you will reach the point were its possible to be off grid and worth while, or there will be a day when we have two power circuits in a house, one low power for LED light etc, and a higher power one (240V).
Thats interesting, I assumed higher loss with 240V. Each LED needs to be dropped and has to have half cycle protection? so wouldnt a 12/5V circuit be better?We have already reached this point here. Low voltage LED circuits are not a good idea though because of much higher losses in the wiring.
Thats interesting, I assumed higher loss with 240V. Each LED needs to be dropped and has to have half cycle protection? so wouldnt a 12/5V circuit be better?
I dont get the higher loss? or is it distance to each house?
so working on an assumption that beer is now £3.20? a pint, they used to cost over 2 pints, or in todays beer over £6 each!!!
