Laser-Cut Lego Frames Enclosure

I finally got the panels cut for my USB – four RS232 ports + four 3.3V/5V serial interface today.

The front and back panels are printed circuit boards – a very cost-effective way to get accurate machining and silkscreen artwork. The top and bottom are blue transparent acrylic (got to keep a eye on what's happening in there ). The end panels are plywood for a retro look – contemporary to a lot of RS-232 devices!

Looks like a store-bought thing. It's built around the CH348 USB – octal serial chip. A few bucks and pretty simple to use.
