This page is a work in progress. A directory of useful tools and resources. Including any tools that I create myself! Such as: build instructions, calculator widgets, Zoomable GUI for system design… etc.

Interesting article, albeit poorly written, about flexible PCB’s
https://www.pcbway.com/blog/News/What_is_Flex_PCB____An_Overview_of_Flex_and_Rigid_Flex_PCB.html
Interesting overview of EMI/EMC related qualification. https://interferencetechnology.com/mil-std-461g-compleat-review/#:~:text=MIL%2DSTD%2D461G%20makes%20the,net%20increase%20of%20one%20requirement.
Along the research path of microfabrication and lithography, and the history of semiconductor devices, the individual https://en.wikipedia.org/wiki/Bijan_Davari is an interesting point of entry.
Hyugens optics is another valuable youtube resource. The critical parameter to minimize is gate capacitance of individual CMOS cells and this leads to a reduction in dynamic power.

PMMA Resist
Pmma resist is the standard for electron beam lithography
SYZYGY is an open standard for FPGA peripherals similar to Diglent’s PMOD standard. These are useful to cover in blog posts for rapid development. https://syzygyfpga.io/

This is a fascinating post about building a pick and place. I think a gear reduction approach might be nice though, the issue with free bearings is that its still basically dependent on human motor skills
Should I ever need to get an mp3 codec or similar running to bring more audio channels through a limited amount of bandwidth… nice overview https://soundbridge.io/audio-formats-file-types/
Good to know about optical subassemblies https://www.glsunmall.com/fiber-optic-articles/what-is-tosa-rosa-and-bosa-in-optical-transceivers.html
good to know about fiber termination types https://community.fs.com/blog/pc-vs-upc-vs-apc-connector-selecting-the-right-fiber-connector-type.html
good place to get resources on nanofabrication https://nanohub.org/
good to know about sma vs smb https://blog.elecbee.com/the-difference-between-sma-connector-and-smb-connector/
TOOLS AND CALCS to build into this site:
frequency / period with orders of mag calc. e.g. a 10 ns resolution measurement needs a 100 MHz BW probe.
power dB to signal dB… general dB calcs
power budget
signal budget
satellite link budget with pass quality equalization
