SpaceX CRS-5 Launch

2015-01-12 Dan

Let’s start Monday morning with a blast.

I’m working hard right now on my robot arms. As you know from my about page, when they’re up and running I want to ship them to the moon and build a moon base by remote control.

SpaceX is my favorite choice right now because they seem to be the only company that’s really trying anything new. In most rocket launches the rocket falls apart as it goes up, throwing off parts it doesn’t need when they have been used up. These parts are really really expensive and are never used again. SpaceX is trying to land the expensive throwaways on a drone boat so they can be reused, saving money and lowering the cost of shipping to space.

Excellent.

Also there are some Makelangelo upgrades in the works. Expect a software update later today.

How to fix 9 common Polargraph drawing problems

Here is a picture I’ve correctly drawn on a polargraph machine. Here are nine examples of common mistakes that can happen on any polargraph drawing robot – including the Makelangelo – and how to fix them. They are all a result of miscalibration. These should only need fixing once, so take the time to do it right: Slow is smooth, smooth is fast.

DIY 3D Printing a Slew Bearing

2014-05-06 Dan

Printed this bearing to try and reduce number of parts and shave weight without breaking the bank.  Pretty good for a first try.  Right now I’m mostly getting ready for the Bay Area Maker Faire, then I’m going to put some bevelled gears in the wrist and move up to 5DOF.  There’s a lot of people asking for a 3D printer nozzle on this thing, so I’m going to get in the gear and see about making that happen over the summer.

Oh yeah, follow the link above to get the STL file and the Instructables link if you want to make your own.  Please tell your friends, skull, and comment.
