Now it works with IR + PIR control. I had to sacrifice the onboard LED for that. Why aren't there any DIP-10 chips?

Added a description.

Sensitivity is not adjustable. Range is a couple of meters. It needs some external intelligence to be useful as a lamp controller (off-time hysteresis). By changing the position of a 0-Ohm resistor (from L to H) it can be adjusted to re-trigger-able mode. When using a micro this is not really necessary.

I bet the designer tested it him or herself. This works perfectly.

I got these from Adafruit. I simply couldn't find something similar locally. They should work well for remote controlling all sorts of LED gadgets. Now I need to have a look at decoding the IR data. Some C- code .

Pretty close to what the Arduino measured ;-) Some C- code for receiving that kind of data.

Forgot to get the quartz, diode footprint doesn't quite match, still missing the programming adapter board... the usual stuff.

The thing is real. I just removed the headers by overlaying rendered gerber files.

Completed the first board of the 2nd revision. The 3rd revision has some minor changes, more suitable footprints and better locations for parts. This one works nicely too. Total power consumption is about 6mA - with the LED on (powered by the pull-up). So far the only power-relevant code shuts off the analog comparator. Maybe the ADC should go to sleep as well.

The MCP1804 is quite a good regulator, very low standby consumption, smaller footprint too. So I switched to that and shrunk the board by 2mm. Can't make it much smaller without moving to insanely small parts. Code and design files . Let's see how long I have to wait this time. On the positive side, OSHPARK shouldn't be affected by this year's Chinese New Year (10. and 11. Febr. 2013) and the accompanying celebrations.

It works reasonably well, although in real-world applications the IR sensor would probably have to be placed elsewhere (i.e. add wires).

If there should be a reincarnation of this board at some point, it would probably have dedicated PWM drivers. To allow for further shrinkage, I will have to use a tinier AVR package and probably get a hot-air thingy.

No more chip frying... assuming I don't reverse the supply voltage ;-) I had to sacrifice some of the axial symmetry. Oh well...
