Robchiz Posted April 10, 2011 Author Share Posted April 10, 2011 .....everything started from front panel cutting and drilling. Main project materials is stainless steel and aluminum profiles. Link to comment Share on other sites More sharing options...
Robchiz Posted April 10, 2011 Author Share Posted April 10, 2011 After cutting and drilling goes accurate polishing. Link to comment Share on other sites More sharing options...
Robchiz Posted April 10, 2011 Author Share Posted April 10, 2011 With the back panel do the same thing. Stainless steel just eat's one by one cutting disc's , thath's why i like to use my old school "Dremel" Link to comment Share on other sites More sharing options...
Robchiz Posted April 10, 2011 Author Share Posted April 10, 2011 S.Steel is still hungry and eats last useful diameter drill bits so back panel drilling i leave for later time. Next step is aluminum profile assembling for sides from smaller profiles to get desired case length.

Robchiz Posted April 11, 2011 Author Share Posted April 11, 2011 Next step is electronic part. Important thing is PSU, and there is 2 choices: buy PicoPSU or create my own PSU I choose to get more experience building psu's and spend less money. My PSU design is based on buck-boost controllers with max. power ~80W (enough for Atom). Mobo with created-assembled power supply start like a charm. After deeper test i measured to big voltage spikes and was disappointed because i don't have time to fight with them. Also i think that overall looking must be much better with PicoPSU so ordered that small good thing. Experiments with own design PSU: Link to comment Share on other sites More sharing options...
Robchiz Posted April 11, 2011 Author Share Posted April 11, 2011 For power on/off i use unusual own design touch sensitive button with LED lighting. There are two lighting colors for two modes: Power off/hibernade and Power on/standby. Power off/hibernade mode : Power on/standby mode : Link to comment Share on other sites More sharing options...
