[Carl] sure has come a long way with laser modifications, now introducing his portable RGV Full Colour Laser. Although it feels just like yesterday when he showed us his green spiro and his Lego diffraction grating projector.
But enough of the past, the RGV laser is built using a White Fusion Mixing Kit and his own Full Colour Driver Extension. We couldn’t find any circuit diagrams or code to build your own at the moment, but it appears fairly straight forward and you can always take a look at [c4r0's] Colour Laser.
Everyone Remembers Free day right? [The Ideanator's] Bus Pirate came in such a nice red box – he decided to make it his permanent case.
[Chico] is in the middle of making a CNC, but decided to make some music with the steppers in the mean time.
What looks like an old wooden box is actually [Ludvig's] super sweet retro arcade cabinet. Complete with a giant emergency stop red button.
Who says Legos are dead? [Carl] used them to create a simple and cheap diffraction grating projector. Including video!
[Torchris] used an Ethernet shield exactly as it was designed, sending data over Ethernet. Still a nice hack for those needing help working with Ethernet shields and Arduino.
Finally [Robert] let us know about a friends Arduino Binary Clock. But we think his elegant use of tape and a sand blaster to engrave glass is cooler.
