Lord Helmet

I want [inhale]...[exhale] this PCB factory operational in fiiiiive minutes!
Inspired by this drill file output. Too bad I didn't find a free spot on the silkscreen for this one.
Looks a bit like...

the heavily asthmatic lead character of the Star Wars movies. This is in fact the drill pattern of a printed circuit board that I'm waiting for.
Maybe I should give it the code name 'Lord Helmet' ;-)
Added another 8x 0805 LEDs

I had to change the small vias to 25/13mil. Nevertheless the board was barely routable. Initially I wanted individual control of the 0805 LEDs, but that was impossible to route. Now they all just turn on/off.

Yesterday I saw a light bulb with PLCC2 LEDs. They were 'speaking to me' ;-) So I just added a 'dual footprint' to the board. If you only need one color, just use PLCC2 LEDS and only populate one LED driver chip.

A small SMD potentiometer of the 'Bourns' brand. 2kΩ
I ordered 100 and got 101 ;-)
Now where are my PCBs, the P-MOSFETS, ... I really despise waiting for deliveries.

The switch died, so I put in a LED

This LED indicates that the lamp is on ;-)
It is driven from the same pin that feeds PWM to the PT4115.

I've added a signal wire going to the 'dim' pin and wires getting the rectified voltage.

It works beautifully now. The lamp starts up at full brightness and can be controlled by touching the contacts on either side. The ATtiny13 only has one 8-bit timer, so PWM resolution is limited - but sufficient.
PT4115 full blast

This time I just soldered a wire to the 'DIM' pin (otherwise floating) and connected that straight to one PWM output.
