Software developer (in love with C++). Hardware geek (FPGA's, STM32, AVR, crazy stuff from discrete components), love LED indicators (7-segment, alphanumeric). Trying to understand ASIC design & manufacturing better at the moment. Also, trying to wrap my head around lens design, but that is not going to be that easy.

comment Can light emitting diodes be used to generate UV wavelengths?
Now 365nm LEDs are quite common, and even shorter-wavelength ones are available though very expensive.

comment PCB and trace design for high-speed TTL
@secretformula Oh, I was so young and optimistic :-) Not even close, stuck in simulation. Hopefully will get it done eventually (in like 5 more years).

comment Precise measuring of frequency with high-speed ADC
@pjc50 That implies rubidium frequency standard, which could optionally be fine-tuned to GPS clock. Reference and target clocks are around 10Mhz, which could be further multiplied/divided by PLL's as needed. ADC might be something like 100 MSPS / 14-bit.

comment How do filament LED bulbs work, looking very similar to incandescent bulbs?
Implementing multilayer radial LED structure with today's materials is nearly impossible. GaN-based materials are just waaaay to tricky even for planar substrates.
