Vik Olliver developed the RepRap 3D printer, an early draft of the holy grail of 3D printing: a printer that can replicate itself. Since then, RepRaps have taken hold of people’s imaginations and workshops around the world. Vik currently runs his own out of his basement, driven by Linux software running off of an XO.
To add another layer of awesome, Vik has been turning out gen-3 viewfinders for the XO. Cruder than gen-2, perhaps, but 10x cheaper. For those of you who don’t regularly use your XO as a camera, here is the evolution of the XOview viewfinder:
- from Mike Lee’s lego construct (modeled here by a fine shock of curly hair)
- to a beautifully precise 3D-printed model by Phil Carizzi, the next month (modelled here by an enthusiastic Cici)
- to this simpler and lower-cost reprapped version, first noticed by us in the taniwha’s hands last fall.
But I just today saw my first of these third-generaiton XOviews, when Mike passed out a stack for our Cambridge office. (Thanks!)
As to how an XO is driving this machine making XO parts, OLPC NZ posted a lovely ‘how do they do that?’ video last fall as well. I’ve watched the video a couple of times, and I still want to see it in person. Are any local reprap owners willing to give a live demo?
