TI deadtime generator
It seems they took Win's circuit way too carelessly: According to the schematic, they use SN75LVC2G14 as the Schmitt trigger. The datasheet says V_T+ is 2.2--3.7V (@5.5V), while V_T- is 1.4--2.5V and...

photodiode
This is a Hamamatsu deep-UV (190 nm) photodiode. They neatly avoid UV absorption in the window by not having a window. https://www.dropbox.com/s/wm3a3cpxa8tcarg/S8551_1.JPG?raw=1

Silicon detector response at 1064nm
I know that the tempco of a Si photodiode is very low up until the point th at the responsibility begins to drop (about 950 nm for a Hamamatsu S1336 di ode). At 1064nm there is about a .6% / degree C...

Re: Gerber print driver
Indirect method would be intercept the Gerber to HPGL output stream and then feed it into a rasterising image application and print from there. You could always write one.

Ultra-efficient bucks
I have been recently working on my current-fed converter. Its only advantage is that it works, but not exactly as advertised. This circuit deserves a separate autopsy thread, but the scope for some...

Wireless keyboard

Re: Cheap Chinese BJT
I'm sorry, when the price of a full reel drops to $10, don't buy in. Pay a bit more for a stable known product. Hottech's semi's are probably fine, but it's not worth it.
