Hello, I would like to try making your tiny tube amplifier and was wondering if you would mind sharing the schematics 

  Are you sure? yes | no

Hey there, would you mind sharing your design files for the USB HUB thing? I can't get mine to work and need something working tom compare designs :D My project is this: #WiFi and USB for pocketbeagle 

  Are you sure? yes | no

I vaguely remember you having computer in SD card (and perhaps some other projects), but I can't see the project anymore... what happened to it?

Hah, was just about to ask... What technique do you use for making your PCBs? As Alpha Charlie said, they're very clean looking!

  Are you sure? yes | no

Hello Esot and Alpha (sorry for very slow response). PCB are made by the CNC aka LPKF (actually not LPKF but a Japanese company, Mits). In my case, limit of PCB fab. is 0.5 mm pitch, and for its completion I always do "same pattern engraving by several times". Three times engraving for one face leads to good result. I know PCB services will provide more clean and stable result, but for my purposes (just prototyping) CNC is enough..

  Are you sure? yes | no

Excellent! Shows what quality a CNC can do... I'm impressed and motivated to get my home-made PCB-router working. I was definitely planning on shards of metal and fiberglass between all the traces as a fact of the technique!

(@Alpha Charlie, did you see Kodera's response?)

Nevermind your tools, you've got some impressive projects, here!

  Are you sure? yes | no

Thank you for the skull!      

BTW - Your PCB's are very clean looking. Nice work!
