bad current regulation

This is how the current limiting of my power supply reacts to 'shorting' the output into a 0.22R resistor. Various I and U settings.

Some shrinking tube
New clip
Lecroy probe alligator clip
Lecroy probe ground clip cable

This is the always too short cable of the probe's ground clip. It is almost impossible to solder as the insulation starts to disintegrate at 120°C.
Quite small PIR sensor

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.
Upgrades!

Now it works with IR + PIR control. I had to sacrifice the onboard LED for that. Why aren't there any DIP-10 chips?
Plugged right into the ISP header.
Fresnel is everywhere
And this is why...
Ohhh, didn't expect that.
Finally got these, too.

A new negative record - 4 weeks and a couple of days... I ordered these boards a couple of days before the other ones and got them a couple of days later...
