Ok,

So Raspberry Pi Zero is out for $5.  https://www.raspberrypi.org/blog/raspberry-pi-zero/

This makes the fully functional Raspberry Pi competitive with Ardunio for taggers and give alot more capability.

Time to resurrect this thread?
Also pay attention to it.
Very interesting!
How much energy it consumes?

Is it?

Very Similar to A+
This shows us clearly that the Zero uses pretty much the same amount of ‘juice’ as the A+. This is hardly surprising, given that the processor is the same and there’s not a lot else on either board (just USB keyboard/mouse dongle). They both draw about 100 mA when idle and 140 mA when pushed. It’s possible that the peak current on loading LXDE is a tad higher on the Zero because the CPU is overclocked to 1 GHz and the core L2 cache is also clocked faster – but it could equally just be random measurement error. WJDK!

Voltage under load was 5.09V, so the Pi Zero uses 0.5-0.7 Watts.




That power draw is running wide open.

In any case - the theme is interesting, promising direction.
If that - I'm on the team. ;) :)

Old thread ... but still relevant.

I'm working on this now... but since I'm a Java dev, I'm trying it in Java on a RPi zero w.  First, I tried using pi4j for it all, but it's too slow to pulse the IR in under 600 microseconds. :( Never thought I'd ever run into that kind of problem.  Java is definitely fast enough on the pi zero, but the pi4j lib is not.

Now I'm seeing if I can use diozero http://rtd.diozero.com/en/latest/ and lircj https://github.com/caprica/lircj on a raspberry pi zero w.  Just started that last night and today.  I'll post stuff here as I go along.
