Just finished up our build here in San Francisco and thought I'd share a few photos.
We followed the 2.0 beta spec pretty closely. Did all the machining at Tech Shop, a maker space here in SF -- the acrylic was on the laser and the Shopbot, the frame was on the vertical mill, the aluminum for the power supply was on the Tormach CNC. Got the PCB printed at a local shop and hand soldered all the components (wouldn't recommend it!). Everything seems to be working well; all the actuators and sensors are working and connecting through to the UI, and even the webcam is coming through with a little hacking on the UI code.
Overall, was a lot of fun and learned a ton along the way - feel free to reach out if you have any questions! Thanks to the MIT team for a great experience!
